1. Introduction
Thank you for purchasing the CANDooPro Diagnostic System! The system has numerous
features to help you effectively maintain and diagnose Sea Doo Watercraft, Yamaha
Waverunners, Kawasaki Jet Skis, and Ski Doo Snowmobiles.
Please refer to the Help sections applicable for the make and model of powersports you wish to
diagnose.. Please also note that the Sea Doo and Yamaha Sportboats use basically the same
control systems as the Sea Doo and Yamaha Personal Watercraft. In general, if you are working
on a Sportboat, please refer to the section that details the type of engine you are working on.
If you cannot find the answer you are looking for in the Help files, feel free to contact us via:
Our forum at http://forums.candoopro.com/
Via Email at sales@candoopro.com
Or via phone at 1-218-4CANDOO (1-218-422-6366)
Families of Sea Doo Watercraft:
The Help files are structured by the type of engine and electronic control system. This is because
the main differences between engine types and control systems affect both the way that you
connect to the watercraft and the features that are available with the electronic control system on
that type of watercraft.
Here is a general listing of the common Sea Doo Watercraft families:
2-Stroke carbureted models: (Use DESS protocol to connect and
communicate)
7
CANDoo Professional
Sea Doo began using the DESS system on a few models in 1995 (e.g. the 1995 XP800), and
began using the DESS system more broadly in 1996. Please note that there were a few models
built until around 2000 that did not use the DESS system (like the GTS model) Please note that the
CANDooPro system will not work on systems that do not have DESS. Sea Doo built the last
carbureted model in 2005 (the 2005 GTI)
2-Stroke RFI models (the early 1998-2004 models that use DESS to
communicate)
The RFI came out in 1998 and used the same way to communicate (DESS) as the carbureted
watercraft built at that time. The last RFI to use the DESS communication was the 2004 GTI.
2-Stroke RFI Models (the late 2004 and 2005 models that use CAN 250K to
communicate.)
Sea Doo introduced the 3D RFI in 2004, using a totally different engine control system than the
earlier RFI models. In 2005, they switched the GTI over to the same control system. 2005 was the
last year of production for both the 3D and GTI RFI models
2-Stroke DI Models (2000 to 2007 using the DI protocol to communicate)
The Direct Injection watercraft was introduced in 2000. The DI electronic control system uses a
different means of communicating than the 2-Stroke carbureted and RFI watercraft. The DI system
was last used in the 2007 3D.
4-Stroke 4-TEC models (2002 to present, using CAN 250K and CAN 500K to
communicate)
Sea Doo introduced the 4-TEC system in 2002, and is the only system in production today for Sea
Doo watercraft. The system uses the same standard protocol as the 2005 RFI (called CAN), and
used a speed of 250K until they came out with the iControl system in 2009. The iControl models
(like the GTX iS, 2012 RXP-X) uses a faster 500K version of the CAN protocol to communicate.
Families of Yamaha Watercraft:
The Yamaha Waverunners are more straightforward than either the Sea Doo or Kawasaki
watercraft, as there is only one way to connect to them, regardless of year or model. However,
please note that there are quite a few differences in the electrical systems, depending upon model.
The CANDooPro system automatically detects the features appropriate for each model. Yamaha
began to offer diagnostic capabilities beginning in 2003. (the 2002 and earlier WaveRunners do
not have any external diagnostics capabilities, although there are limited fault capabilities for some
earlier models through the dash gauges.)
There are two different families of Yamaha Waverunners:
2-Stroke GPR 1300 (2003 to 2008)
All 4-Stroke models (2003 to 2012)
8
CANDoo Professional
Families of Kawasaki Watercraft:
Kawasaki began offering diagnostics with the 1999 STX-1100 Direct Injection skis, but this was
because the Fuel Injection system was supplied to Kawasaki by Fitch. Kawasaki started offering
external diagnostics capability upon the release of the 4-Stroke STX-12F in 2003. Setting up a
diagnostic session with a Kawasaki Jet Ski is much more complex than the other brands, as
Kawsaki apparently added this capability as an afterthought. While the early DI diagnostics is
relatively plug and play, the 4-Stroke skis all require the use of an additional bypass cable to keep
the ECU powered up during the diagnostic session. Getting at the proper location to install the
bypass cable can be time consuming, compared to the other brands. Once connected, the
CANDooPro system automatically detects the features appropriate for each model.
There are three different families of Yamaha Waverunners:
2-Stroke STX-1100 DI (1999-2003)
The 2-Stroke DI system came out in 1999. These systems were provided to Kawasaki by Fitch,
who also supplied Polaris and Arctic Cat/Tigershark in the same era. They all have fairly basic
diagnostics capabilities, with some unique injector capabilities, as the injectors were matched to the
ECU.
4-Stroke STX-12F/15F (2003-2012)
Kawasaki began offering diagnostic capabilities with the launch of the STX-12F in 2003. All the
skis in this family, including the 2008 STX-R, share the same basic set of capabilities
4-Stroke Ultra LX/250X/250LX/260X/260LX/300X/300LX (2007-2012)
Kawasaki began a new diagnostic system with the introduction of the 250X in 2007. While this
system has more capabilities than the earlier models, it has a disadvantage that the ECU
communications is much slower than earlier models, and extremely slow compared to either Sea
Doo or Yamaha models.

2. Getting Started
The help files are structured in two main sections:


The Getting Started section, which covers the basics about the CANDooPro
system
The main Vehicles section that covers specific details and features about working
with specific vehicle types
Please review the Getting Started section first to familiarize yourself with the
CANDooPro system, then you can jump to the specific section pertinent to the type
of vehicle you are working on.
2.1 Computer Requirements
CANDooPro has been designed to run on most laptop and desktop
computers available today that run the Windows operating system. (It will
NOT work with Mac operating systems, or Linux-based systems!)
Basic Computer Requirements:
1. Windows XP, Vista, or Windows 7 operating system (will not work with older Windows 2000, ME,
98, or 95)
2. USB port
3. Internet connection (required for downloading program and updates; not required while using
system)
Some points to consider:
1. The CANDooPro Developers used inexpensive Acer AspireOne Netbooks for development and
testing of the system. The reason we did this is to make sure the system will work well with a basic
low-cost computer.
2. Inexpensive Netbooks like the Acer, HP, Asus, or others can be purchased for less than $300 at
your local Walmart, BestBuy, Target or other retailers.
3. You can certainly use a more expensive laptop or desktop computer, especially if you are a
home user and only using the system occasionally. My experience is that the nicer the laptop is,
the more likely that I will drop it off the ski, or get it really greasy!
10
CANDoo Professional
4. The downside of a small inexpensive computer is that the screens are a little hard to read,
especially outside.
2.2 CANDooPro Hardware
CANDooPro Hardware
When you purchase the Sea Doo, Yamaha, or Kawasaki version of the CANDooPro System, it will
come with everything you need to work on that brand of vehicle. This section will describe the
hardware included with the system.

2. “ Waking up” the engine ECU to enable the Candoopro system to talk to the ECU
Connecting the Diagnostic Cable to the Waverunner:
Some Yamaha engines (like the outboard motors) have a dedicated 3-pin diagnostic connector ,
18
CANDoo Professional
but Waverunners do not have a dedicated diagnostic connector. The gauges/clusters on
Waverunners “ speak” to the ECU in the same way that their diagnostics tools communicate with
the ECU, so Yamaha Waverunners have a standard 3-pin connector in the front storage area that
is used to communicate information to the cluster during normal ski operation, and is used for the
diagnostic tool (Candoopro diagnostic system) for a diagnostic session.
Steps to connect:
1. Locate the 3-pin cluster/diagnostic connector in the front storage compartment of the ski. You
may need to open an access panel on some models to get to the connector. The connector is a
three-pin dark gray connector:
2. Disconnect this connector, and plug the Candoopro Yamaha adapter cable light gray connector
into the mating connector on the Waverunner harness:
19
CANDoo Professional
3. You are now ready to “ wake up” the ECU and start a diagnostic session.
Waking up the ECU:
In order to initiate a diagnostic session, you need to “ wake up” or turn on the ECU. This is done
by starting the ski. (or attempting to start the ski if it will not run!)
1.
Start the Waverunner engine. If you wish to do an active diagnostic session while the
engine is running (for example, using the engine monitor function, or to drop a cylinder
while running) please follow the instructions and warnings in the service manual for this
vehicle, and make sure you supply cooling water to the engine per the service manual.
2. If you do not wish to run the engine while doing diagnostics (for example, to read and clear
faults) you can just start the ski, start the diagnostic session with Candoopro, and shut off
the engine. Once the ski is in diagnostic mode, the ECU should continue to stay active. (if
it should happened to shut down, just restart the ski and start the diagnostic session over)
Starting the Diagnostic Session:
When the Candoopro application is running, and the ECU has been woken up, you are ready to
start the diagnostic session.
20
CANDoo Professional
Once the ECU is woken up, the Candoopro application should detect the Yamaha ECU, indicated
by the ski icon on the lower left of the screen changing from red to green, and the status should
change from “ Looking for Vehicle” , to “ Yamaha Detected” .
Once “ Yamaha Detected” appears, go to the upper left of the screen, select “ Vehicle” , then
“ Read Vehicle” .
The Candoopro system will read the data from the ECU. You are now ready to read and clear
faults, view operating history, activate various functions available for that particular model.
General Faq’ s:
• CANDoo Professional checks for updates on startup, if there is an active internet connection.
• The hardware box must always be connected to the PC when you startup the program to enable
the system to check for new updates.
• If you are using wireless and get out of range, it can cause CANDoo Professional to freeze up
while trying to connect to the website on startup. We suggest disabling the wireless on your laptop
if you are moving out of wireless range.
• Make sure you have a fully charged battery, failure to do so can cause data corruption!
• When you are done, always close the program first before disconnecting the USB cable to the
Candoopro box. If you disconnect the USB cable before closing the program, the program will
freeze and you may need to stop the program manually via the Task Manager to exit the program.

3.1.1.1 Connecting & starting a session
To connect to a 2 Stroke DESS system, and start a
session (Applicable for 1995-2005 carbureted and 1998-2004 RFI
models, not DI models)
1. Connect the 9pin/6pin adapter cable to the CANDoo box, by inserting the 9-pin end of
the cable into the Vehicle connector on the CANDoo box.
40
CANDoo Professional
NOTE: The thumbscrews on the cable do NOT attach to the box! This was
intentional by design, for a very good reason. You will notice that the
CANDooPro cables are very strong and heavy, and the CANDooPro interface
box is very light. If we put the mating nuts on the box so the cable is
fastened tightly to the box, and the box falls off the bench or ski while you
are working on it (which WILL happen!), then the internal connection from
the box connector to the internal PC will be damaged. Without the nuts, the
cable connection will simply pop off the box if it falls, so the box connector
will not be damaged.
2. Connect the DESS post adapter cable to the 9pin/6-pin cable, by sliding the two cables
together until they click..
41
CANDoo Professional
3. Insert one end of the USB cable into the USB connector on the CANDooPro box.
42
CANDoo Professional
4. Insert the other end of the USB cable into a spare USB port on your computer.
43
CANDoo Professional
5. Startup the CANDooPro application.
NOTE: Upon startup, the CANDooPro application contacts the CANDooPro application server over
the internet to check for new updates. Please note that if you have a wireless connection to the
internet, and your computer has a weak (or no) connection to the internet when you launch the
CANDooPro application, it will take some time for the application to launch. (this is because the
CANDooPro application attempts to contact our server to check for updates. )
If you have a weak (or no) internet connection in your shop, it is advisable to turn off your
computer's wireless connection if you have the most recent updates, as it will allow the program to
launch much faster.
Upon launch, the program will show the following screen:
Notice that when the program launches, it gives indication of the program connection status at the
lower left hand of the screen, as follows:
44
CANDoo Professional




USB Connection Status indicates if the CANDooPro box is communicating to the computer
over the USB bus
o Green is connected
o Red is disconnected or not communicating
Vehicle Connection Status indicates if the CANDooPro system has detected or is
communicating with the vehicle
o Green is detected or communicating
o Red indicates no vehicle is detected or is not communicating
Number of Connections indicates the total number of modules on the Vehicle that are
communicating with Candoopro system
o Zero indicates no modules are communicating
o One is typical for most Carburated, DI, and RFI vehicles (MPEM)
o Two is typical for early 4-tec models (ECU and MPEM)
o Three is typical for some later 4-tecs (ECU, MPEM, Cluster)
o Late model iS vehicles can have 5 modules communicating
Current Process shows the current activity
At this point, the CANDooPro program is looking for communication from the ski, and the zero
indicates that it does not have any communication with a ski.
6. Attach the DESS Adapter to the DESS post on the ski.

Place the DESS adapter upright and to the side of the DESS post as shown in the photo
below:
45
CANDoo Professional

Slide the DESS adapter over the DESS post as shown below, with a quick motion. You
may need to wiggle it a bit to enable it to slide all the way on to the post:
46
CANDoo Professional
The DESS Adapter contains a magnet, which closes the reed switch in the DESS post, and turns
on the MPEM. The MPEM should start communcating with the CANDooPro system. Once the
CANDooPro system detects communcation with the MPEM, it should indicate that it is talking to the
MPEM by a change in the status bar on the lower left of the screen.
You should see the Vehicle Connection icon change from Red to Green, the number of
connections change from zero to one, and "DESS Detected" appear in the lower status bar, per
the screenshot snippet below:
The vehicle is now ready for a CANDooPro session!
47
CANDoo Professional
7. Reading Information from the MPEM
After sliding the DESS adapter onto the post, click the Vehicle tab at the upper toolbar of the
screen, and click "Read Vehicle".
The CANDooPro system will now read the information from the MPEM. On most DESS skis, you
will also hear a series of beeps from the buzzer during the transfer of data.
IMPORTANT NOTE: You have a very limited amount of time to read the vehicle after you
slide the DESS adapter onto the post, typically 15 seconds. If you do not read the vehicle
within this time window, the green vehicle icon will change back to red, and the Current
Process will change back to "Looking for Vehicle". You can either remove the DESS
adapter and slide it back on to reactivate the MPEM, or simply just press the Start button.

KeysOverview:
The DESS keys/lanyards contain two distinct critical parts:


A powerful magnet
A microchip with a 64 bit serial number
The DESS post on the vehicle contains a reed switch, a center post, and a grounding ring around
the outside of the post. When a DESS key is inserted on the post, the magnet in the key closes the
reed switch in the DESS post. This "wakes up" the MPEM from hibernation, and the MPEM sends
out a signal on the center of the DESS post. Since the DESS key makes contact with the center
lug and the grounding ring, it sees this signal from the MPEM, and it sends its internal serial
number information to the MPEM. The MPEM compares this serial numbers to the serial numbers
contained in its internal list of keys.
If the serial number of the key matches one contained in the MPEM internal list of key serial
numbers, the MPEM gives the 2-beep signal and allows the operation of the vehicle. However, if
the serial number does not match, it gives the single long beep, and does not allow operation of the
vehicle.
The MPEM for 2-stroke Sea Doo's allows storing up to 8 key serial numbers in its list. CANDooPro
allows you to manage the list of keys, to add new keys up to a total of 8, and to erase keys.
The carbureted 2-stroke skis only have one type of key function available (Normal Keys). Please
note that ALL Sea Doo DESS lanyards are identical internally. They simply use a different color
float for the different function keys, (Normal Keys are Yellow, Learning Keys are White, Rental
Keys are Orange). You can use any kind of key for any purpose. For example, you can use a
White Learning key for two stroke carb skis, as it will be programmed in the MPEM as a Normal
key.

(See
3.1.1.2.2.2.4)
Erasing Keys:
Often you will find that the key listing contains a number of keys that are no longer used. This can
happen over the years as keys are lost, and new keys are added without removing the old key
numbers. Candoopro makes it easy to remove these old unused key numbers.
To determine if your listing contains old, unused key numbers, simply test each key you have with
CANDooPro, write down the serial number of the key, and compare it to the ones in the list. You
can then remove any that are not valid.
60
CANDoo Professional
To Erase a Single Key:
For any actions to be performed on keys, click on the far left column in the row for the particular key
you wish to delete. The entire row for that key must be completely highlighted in blue:
Once you have highlighted the key you wish to delete, simply click "Erase Selected Key", and the
selected key will disappear from the key listing:
Now that the key has been deleted, you must Write this change into the MPEM. Select "Vehicle" in
the upper tab, then "Write Vehicle".
61
CANDoo Professional
The CANDooPro program will write the information into the MPEM and read the information back
from the MPEM to ensure the information was written properly.
To Erase All Keys:
Pressing the "Erase All Keys" button will remove all keys from the listing.
Note that if you erase all keys, you must add back at least one key to the
listing before writing the change, otherwise unpredictable results may occur!
After you have added one or more keys to the listing, then you can write the change into the MPEM
with the Vehicle, Write Vehicle command.

Adding Keys:
The MPEM can store up to 8 keys. To add a new key, you must have an available key slot (empty
row) in the key chart. If the chart has all 8 keys filled, you must erase a key before CANDooPro will
allow you to add a new key.
To Add a new Key:
Insert the key you wish to add to the MPEM onto the post on the CANDooPro interface box.
Ensure the key is pushed all the way down onto the post and is square on the post.

Disabling DESS
The developers of CANDooPro have included an experimental feature to disable the DESS
function. The reason it is called "experimental" is because it doesn't always work, and appears to
render some early MPEM's useless. After turning a few early MPEM's into expensive
paperweights, we decided not to do a full listing of what MPEM's it works on, and which it doesn't.
We have had good success with 97 and newer MPEM's that are not installed inside the sealed
electric boxes.
Users of the CANDooPro system are strongly advised not to disable dess on your MPEM's unless
you accept the risk that it may become inoperable. We have successfully disabled DESS on a few
older MPEM's for the 717 engine, but have noticed that the procedure kills the MPEM's on the 9596 787 engines as well as the 98-99 787 engines installed in the X-4 hull (like SPX).
Disabling DESS:
In the Keys tab, select the Disable button. A box will warn you that you are about to perform a
risky operation.

To change Ignition Settings:
CAUTION: CANDooPro gives the capability to change several ignition settings.
The only documented setting is the Ignition Correction setting. Please refer to
the Service Manual for the model ski you are working on, and follow the procedure
noted in the manual for properly setting the ignition offset number into the Ignition
Correction setting. Many models also have a Curve and Limit setting available,
but these are not documented anywhere, and we have no idea what effect these
have, or the amount of change. Changing these values could have a detrimental
result, including catastrophic engine failure due to excessive ignition advance.
The feature is provided for tuners and racers that have the means to properly
assess the effects of these changes.
To change Ignition Correction setting:

5. Startup the CANDooPro application.
NOTE: Upon startup, the CANDooPro application contacts the CANDooPro application server over
the internet to check for new updates. Please note that if you have a wireless connection to the
internet, and your computer has a weak (or no) connection to the internet when you launch the
CANDooPro application, it will take some time for the application to launch. (this is because the
CANDooPro application attempts to contact our server to check for updates. )
If you have a weak (or no) internet connection in your shop, it is advisable to turn off your
computer's wireless connection if you have the most recent updates, as it will allow the program to
launch much faster.
Upon launch, the program will show the following screen:
Notice that when the program launches, it gives indication of the program connection status at the
lower left hand of the screen, as follows:


USB Connection Status indicates if the CANDooPro box is communicating to the computer
over the USB bus
o Green is connected
o Red is disconnected or not communicating
Vehicle Connection Status indicates if the CANDooPro system has detected or is
communicating with the vehicle
o Green is detected or communicating
o Red indicates no vehicle is detected or is not communicating
Number of Connections indicates the total number of modules on the Vehicle that are
communicating with Candoopro system
o Zero indicates no modules are communicating
o One is typical for most Carburated, DI, and RFI vehicles (MPEM)
o Two is typical for early 4-tec models (ECU and MPEM)
o Three is typical for some later 4-tecs (ECU, MPEM, Cluster)
o Late model iS vehicles can have 5 modules communicating
Current Process shows the current activity
At this point, the CANDooPro program is looking for communication from the ski, and the zero
indicates that it does not have any communication with a ski.
6. Attach the DESS Adapter to the DESS post on the ski.

Place the DESS adapter upright and to the side of the DESS post as shown in the photo
below:
74
CANDoo Professional

Slide the DESS adapter over the DESS post as shown below, with a quick motion. You
may need to wiggle it a bit to enable it to slide all the way on to the post:
75
CANDoo Professional
The DESS Adapter contains a magnet, which closes the reed switch in the DESS post, and turns
on the MPEM. The MPEM should start communcating with the CANDooPro system. Once the
CANDooPro system detects communcation with the MPEM, it should indicate that it is talking to the
MPEM by a change in the status bar on the lower left of the screen.
You should see the Vehicle Connection icon change from Red to Green, the number of
connections change from zero to one, and "DESS Detected" appear in the lower status bar, per
the screenshot snippet below:
The vehicle is now ready for a CANDooPro session!
76
CANDoo Professional
7. Reading Information from the MPEM
After sliding the DESS adapter onto the post, click the Vehicle tab at the upper toolbar of the
screen, and click "Read Vehicle".
The CANDooPro system will now read the information from the MPEM. On most DESS skis, you
will also hear a series of beeps from the buzzer during the transfer of data.
IMPORTANT NOTE: You have a very limited amount of time to read the vehicle after you
slide the DESS adapter onto the post, typically 15 seconds. If you do not read the vehicle
within this time window, the green vehicle icon will change back to red, and the Current
Process will change back to "Looking for Vehicle". You can either remove the DESS
adapter and slide it back on to reactivate the MPEM, or simply just press the Start button.

Keys Overview:
89
CANDoo Professional
The DESS keys/lanyards contain two distinct critical parts:


A powerful magnet
A microchip with a 64 bit serial number
The DESS post on the vehicle contains a reed switch, a center post, and a grounding ring around
the outside of the post. When a DESS key is inserted on the post, the magnet in the key closes the
reed switch in the DESS post. This "wakes up" the MPEM from hibernation, and the MPEM sends
out a signal on the center of the DESS post. Since the DESS key makes contact with the center
lug and the grounding ring, it sees this signal from the MPEM, and it sends its internal serial
number information to the MPEM. The MPEM compares this serial numbers to the serial numbers
contained in its internal list of keys.
If the serial number of the key matches one contained in the MPEM internal list of key serial
numbers, the MPEM gives the 2-beep signal and allows the operation of the vehicle. However, if
the serial number does not match, it gives the single long beep, and does not allow operation of the
vehicle.
The MPEM for 2-stroke Sea Doo's allows storing up to 8 key serial numbers in its list. CANDooPro
allows you to manage the list of keys, to add new keys up to a total of 8, and to erase keys.
The carbureted 2-stroke skis only have one type of key function available (Normal Keys). Please
note that ALL Sea Doo DESS lanyards are identical internally. They simply use a different color
float for the different function keys, (Normal Keys are Yellow, Learning Keys are White, Rental
Keys are Orange). You can use any kind of key for any purpose. For example, you can use a
White Learning key for two stroke carb skis, as it will be programmed in the MPEM as a Normal
key.

Erasing Keys:
Often you will find that the key listing contains a number of keys that are no longer used. This can
happen over the years as keys are lost, and new keys are added without removing the old key
numbers. Candoopro makes it easy to remove these old unused key numbers.
To determine if your listing contains old, unused key numbers, simply test each key you have with
CANDooPro, write down the serial number of the key, and compare it to the ones in the list. You
can then remove any that are not valid.
92
CANDoo Professional
To Erase a Single Key:
For any actions to be performed on keys, click on the far left column in the row for the particular key
you wish to delete. The entire row for that key must be completely highlighted in blue:
Once you have highlighted the key you wish to delete, simply click "Erase Selected Key", and the
selected key will disappear from the key listing:
Now that the key has been deleted, you must Write this change into the MPEM. Select "Vehicle" in
the upper tab, then "Write Vehicle".
93
CANDoo Professional
The CANDooPro program will write the information into the MPEM and read the information back
from the MPEM to ensure the information was written properly.
To Erase All Keys:
Pressing the "Erase All Keys" button will remove all keys from the listing.
Note that if you erase all keys, you must add back at least one key to the
listing before writing the change, otherwise unpredictable results may occur!
After you have added one or more keys to the listing, then you can write the change into the MPEM
with theVehicle, Write Vehicle command.

Disabling DESS
3.1.2.1.2.2.2.4)
(See
3.1.2.1.2.2.3)
The developers of CANDooPro have included an experimental feature to disable the DESS
function. The reason it is called "experimental" is because it doesn't always work, and appears to
render some early MPEM's useless. After turning a few early MPEM's into expensive
paperweights, we decided not to do a full listing of what MPEM's it works on, and which it doesn't.
We have had good success with 97 and newer MPEM's that are not installed inside the sealed
electric boxes.
Users of the CANDooPro system are strongly advised not to disable dess on your MPEM's unless
you accept the risk that it may become inoperable. We have successfully disabled DESS on a few
older MPEM's for the 717 engine, but have noticed that the procedure kills the MPEM's on the 9596 787 engines as well as the 98-99 787 engines installed in the X-4 hull (like SPX).
Disabling DESS:
In the Keys tab, select the Disable button. A box will warn you that you are about to perform a
risky operation.
Simply select Yes, and the write the information to the MPEM by selecting Vehicle and Write

The RFI Faults Page:
The RFI Faults page displays the status of the faults detected by the RFI ECU. Please note that
the detection system of the RFI depends upon the engine to be running to detect most faults. Note
that the RFI Faults page displays a listing of all possible faults; only faults indicated with Active or
Occurred status are problems!
NOTE: Fault P0335, Engine Speed Signal Not Detected will always be active if the engine is
not running!

Fault Code:
The fault codes are special codes assigned to particular problems. More information about the
fault codes can be found in the Service Manual.
Source:
The Source tells you which component is sensing the problem.
State
The RFI Fault system has three fault states:



Inactive
Active
Occurred
Inactive Faults
"Inactive" means the fault is not currently detected; it is not really a fault.
Active Faults
"Active" means that the fault is currently happening now; the underlying problem causing the fault
still exists and must be fixed.
100
CANDoo Professional
Occurred Faults
"Occurred" means that a fault became active at some time in the past, but at this moment, it is not
active.
Working with Faults.
Please follow the steps below:
Step # 1- Start engine. (Ensure your cooling water is attached, and do not run over 5 minutes or
damage to the carbon seal may result!)
The engine must be running for the fault detection system to detect faults
Step #2- Read fault table
Look for the existance of any Active and Occurred Faults.
Step #3 - Address problems noted by faults
Any Active faults must be corrected by repairing the affected component
Step # 4 - Clear faults
Press the Clear Faults button, and the Vehicle, Write Vehicle to save the changes to the MPEM

3.1.2.2 Late RFI Models (2005)
NOTE: This section covers the Late RFI models, which includes the
following models:


2004 3D RFI
2005 3D RFI, GTI LE RFI, and GTI STD RFI
3.1.2.2.1 Connecting and Starting a Session
Connecting CANDooPro to a Late 2005 RFI Watercraft:
The Late RFI models all have a 6-pin Diagnostic Connector to attach the Candoopro system.
WARNING: Do NOT use the Aluminum DESS adapter cable to connect to
a Late RFI watercraft!
The 6-pin diagnostic connector is in front of the VCM/ECU modules, up against the gas tank on GTI
RFI models , and adjacent to the oil tank on the 3D RFI models. It is a 6-pin gray Deutsch
connector that has a special sealing cap on it.
Disconnect the 6-pin connector from the sealing cap:
105
CANDoo Professional
WARNING: Always remember to put the cap back on the diagnostic
connector when you are finished with a Candoopro session! Otherwise your
Maint light will be on and stay on!
Steps for Starting a Candoopro session with the 4_TEC watercraft:
1. Plug the USB cord into the Candoopro box and the PC. The Green Power light on the
Candoopro box should light up.
2. Plug the 9 pin connector on the 9 pin/ 6-pin harness cable into the Candoopro box.
3. Plug the 6 -pin connector on the 9-pin/6-pin harness cable into the diagnostic connector on the
PWC.
4. Start the Candoopro program. Upon launch, the program will show the following screen:
106
CANDoo Professional
Notice that when the program launches, it gives indication of the program connection status at the
lower left hand of the screen, as follows:


USB Connection Status indicates if the CANDooPro box is communicating to the computer
over the USB bus
o Green is connected
o Red is disconnected or not communicating
Vehicle Connection Status indicates if the CANDooPro system has detected or is
communicating with the vehicle
o
Green is detected or communicating
107
CANDoo Professional


o Red indicates no vehicle is detected or is not communicating
Number of Connections indicates the total number of modules on the Vehicle that are
communicating with Candoopro system
o Zero indicates no modules are communicating
o One is typical for most Carburated, DI, and RFI vehicles (MPEM)
o Two is typical for early 4-tec models (ECU and MPEM)
o Three is typical for some later 4-tecs (ECU, MPEM, Cluster)
o Late model iS vehicles can have 5 modules communicating
Current Process shows the current activity
At this point, the CANDooPro program is looking for communication from the ski, and the
zero indicates that it does not have any communication with a ski.
5. Put a DESS key/lanyard on the DESS post on the ski. (Does not need to be programmed to the
ski; it can be any DESS key..) You should hear a single beep if the key has not been programmed
in memory, two beeps if the key has been programmed into the ECU
6. The CANDooPro program should detect the 4-TEC ski, the Vehicle Connection Status
indicator should change from red to green, and the Current Activity bar at the lower left should
indicate "CAN Detected" as well as the speed that it is communicating (2002-2010 models without
iControl connect at 250K, late iControl models communicate at 500K)
7. Select the Vehicle tab at top, select "Read Vehicle ", and the CANDooPro system should begin
to read the information from the modules (MPEM, ECU, Cluster) on the ski
8. Once the information is read from the modules, the main Vehicle page should appear. If you
are using the Limited version of CANDooPro and this is the first time you have connected to this
watercraft, you will be prompted if you wish to have this watercraft count towards your total
available VIN numbers. Pressing Yes will add this watercraft to your list of VIN's used. You are
now ready to begin a diagnostic session.

3.1.2.2.2 Working with CANDooPro
The subjects contained in this section describes the process for
working with RFI data using the CANDooPro system.
In general, you must go thru the following steps to change or modify information in the RFI ECU.
1. Read the modules on the watercraft, using the Read Vehicle command contained in the
Vehicle tab of the program
2. Modify the information (for example, reset service hours, add new key, etc)
3. Write the changes back to the ECU, using the Write Vehicle command contained in the Vehicle
tab of the program:
4. Some changes on the Late RFI models are instantaneous, for example, clearing faults. These
changes do not need to be written to the modules using the Write Vehicle command.

Overview:

CANDoo Professional
The DESS keys/lanyards contain two distinct critical parts:


A powerful magnet
A microchip with a 64 bit serial number
The DESS post on the vehicle contains a reed switch, a center post, and a grounding ring around
the outside of the post. When a DESS key is inserted on the post, the magnet in the key closes the
reed switch in the DESS post. This "wakes up" the ECU from hibernation, and the ECU sends out
a signal on the center of the DESS post. Since the DESS key makes contact with the center lug
and the grounding ring, it sees this signal from the ECU, and it sends its internal serial number
information to the ECU. The ECU compares this serial numbers to the serial numbers contained in
its internal list of keys.
If the serial number of the key matches one contained in the ECU internal list of key serial
numbers, the ECU gives the 2-beep signal and allows the operation of the vehicle. However, if the
serial number does not match, it gives the single long beep, and does not allow operation of the
vehicle.
The RFI ECU allows storing up to 8 key serial numbers in its list. CANDooPro allows you to
manage the list of keys, to add new keys up to a total of 8, and to erase keys.
The RFI models have two main key operation profiles, Normal and Learning .
Normal Keys allow full operation of the watercraft.
Learning keys limit the amount of speed to approximately 35 MPH, perfect for learning/first time
users (or that close friend or relative that always manages to ruin your stuff...)
Please note that ALL Sea Doo DESS lanyards are identical internally. They simply use a different
color float for the different function keys, (Normal Keys are Yellow, Learning Keys are White, Rental
Keys are Orange). You can use any kind of key for any purpose. For example, you can use a
White Learning key programmed as a Normal key, a Normal Key programmed as a Learning key,
etc.

Testing Keys:
To test if the microchip in the key is good, you can use the Test Key function of candoo.
To test a key:
128
CANDoo Professional

Insert the key you wish to test on the DESS post mounted to the CANDooPro box

At the top toolbar, selet Key and then click Test Key as shown below:
If the microchip in the key is working properly, you will see the popup box similar to the one shown
below :
129
CANDoo Professional
The key number shown by the popup box is the 64 bit serial number of the key. (Shown in
Hexidecimal format) Note that this only tests the microchip in the key; it does not check for a weak
magnet.
If you receive a pop up box stating " Key Not Found", try repositioning the key again on the post.
If you still receive the "Key Not Found " message after repeated tries, remove key, clean the
stainless metal contacts on the key with a pencil eraser and try again. If it still will not read, the key
is likely no good.
3.1.2.2.2.2.2.3 Erasing Keys
CANDooPro > Vehicles > Sea-Doo Watercraft > 2 Stroke RFI Models(See 3.1.2) >
Late RFI Models (2005)(See 3.1.2.2) > Working with CANDooPro(See 3.1.2.2.2) >

Erasing Keys
(See
3.1.2.2.2.2.2.2)
(See
3.1.2.2.2.2.2.4)
Erasing Keys:
Often you will find that the key listing contains a number of keys that are no longer used. This can
happen over the years as keys are lost, and new keys are added without removing the old key
numbers. Candoopro makes it easy to remove these old unused key numbers.
130
CANDoo Professional
To determine if your listing contains old, unused key numbers, simply test each key you have with
CANDooPro, write down the serial number of the key, and compare it to the ones in the list. You
can then remove any that are not currently needed.
To Erase a Key:
For any actions to be performed on keys, click on the far left column in the row for the particular key
you wish to delete. The entire row for that key must be completely highlighted in blue:
Once you have highlighted the key you wish to delete, simply click "Erase Selected Key", and the
selected key will disappear from the key listing:
Now that the key has been deleted, you must Write this change into the MPEM. Select "Vehicle" in
the upper tab, then "Write Vehicle".
131
CANDoo Professional
After you select Write, a popup box will instruct you to remove the key and wait until the connect
light is off to complete the write operation. (a box will not popup on 2009 and newer models with
the iControl system; you do not need to remove the key on these models) Follow the instructions in
the box, and especially take note that on 2007 and newer models, you need to take the key off, put
it back on, then remove again to complete the write operation.
To Erase All Keys:
Pressing the "Erase All Keys" button will remove all keys from the listing.
Note that if you erase all keys, you must add back at least one key to the
listing before writing the change, otherwise unpredictable results may occur!
132
CANDoo Professional
After you have added one or more keys to the listing, then you can write the change into the MPEM
with the Vehicle, Write Vehicle command.

Adding New Keys
(See
3.1.2.2.2.2.2.3)
(See
3.1.2.2.2.2.2.5)
Adding Keys:
The ECU can store up to 8 keys. To add a new key, you must have an available key slot (empty
row) in the key chart. If the chart has all 8 keys filled, you must erase a key before CANDooPro will
allow you to add a new key.
To Add a new Key:
Insert the key you wish to add to the ECU onto the post on the CANDooPro interface box. Ensure
the key is pushed all the way down onto the post and is square on the post.
133
CANDoo Professional
Once the key is on the post, click the type of key you wish to add. For example to add a normal
key, click the "Add Normal Key" button. A box will appear indicating the key has been added to
the key listing.
NOTE: If a key is not on the post, is not properly seated on the post, or is not
a good key, you will see an error message "Key Not Found".
Once you have added the key to the list, you must now write the new key into the MPEM. Select
"Vehicle" in the upper tab, then "Write Vehicle".
134

Disabling DESS
The developers of CANDooPro have included an experimental feature to disable the DESS
function. The reason it is called "experimental" is because it doesn't always work, and appears to
render some early MPEM's useless. After turning a few early MPEM's into expensive
paperweights, we decided not to do a full listing of what MPEM's it works on, and which it doesn't.
We have had good success with 97 and newer MPEM's that are not installed inside the sealed
electric boxes.
We strongly advise not to try disabling DESS on the 2005 RFI watercraft

Fault Overview
The 2005 RFI Engine Management System continually checks the various components in the
system for proper operation. If it detects a problem with any component in the system, it will create
an active fault related to the problem. Anytime this happens, the system logs these faults within the
fault table. For many of these faults, it also logs a range of engine operating conditions. Note that
not all faults are stored. Some faults, once fixed, have no record in the fault table.
The Fault Page:
The 2005 RFI fault system displays data associated with faults that have been logged since the last
time the faults have been cleared. For any faults listed in the box on the left side, simply click on
the fault code number to have the page display the information associated with the fault code.
Many, but not all faults will have information stored with the fault that will assist in troubleshooting
the problem associated with the fault.
Fault Code:
The fault codes are special codes assigned to particular problems. More information about the
fault codes can be found in the Service Manual.
Source:
140
CANDoo Professional
The Source tells you which component is sensing the problem.
Status
The 4-TEC Fault system has two fault states:


Active
Occurred
Active Faults
"Active" means that the fault is currently happening now; the underlying problem causing the fault
still exists and must be fixed.
Occurred Faults
"Occurred" means that a fault became active at some time in the past, but at this moment, it is not
active.
Count
The first time the system detects a fault, it adds the fault to the list (if not already there), and
increments the fault counter by one. Note that it only adds one per each time the system has been
powered up. For example, it may detect a fault 20 times during a ride, but it only adds one to the
count during the entire time the watercraft has been running. Next time the watercraft is powered
up and has the fault, it will add one more to the counter. Note that not all faults will have a count.
Hours:
The system logs the engine hours when the fault first occurred.

2005 RFI Fault Diagnosis
The Fault page gives you details about faults logged by the ECU. The following steps can be used
to diagnose issues by reviewing the fault data.
Step #1- Review the Fault data
As described in the Overview, an Active fault means the problem is present now, and an Occurred
fault means it has happened some time in the past.
141
CANDoo Professional
Review the data in the fault table, and review each fault listed in the box on the left hand side by
clicking each fault and reviewing the data associated with the fault.
Step #2 - Fix any Active Faults
Look in the table for any Active faults. The underlying problem causing these faults must be
fixed. Refer to the Diagnostic Procedures section of the Service Manual for the watercraft for
instructions related to troubleshooting problems related to the component(s) indicated by the fault.
Step #3- Analyze the Occurred Faults
Understanding Occurred Faults can be tricky. While transient problems (those that happen briefly
and then go away) will log an occurred fault, not all faults are stored by the system, so when you
shut off the watercraft, the fault is lost. Additionally, if faults have not been cleared for
quite awhile, you may not have a good indication if an occurred fault in the table is still a problem.
For example, you or a customer may notice a fault occur while running the watercraft. Let's say the
Exhaust Temperature Sensor has a bad connector that randomly disconnects. The watercraft may
signal a fault, but this particular fault is not stored. It will show Occurred while the watercraft is
running, but when you shut it off and restart, it may not be present if the connection is OK when you
start.
142
CANDoo Professional
Or let's say you notice an Occurred P0122 TPS fault, with a count of 3. When did this happen? Is
it still an issue that needs to be fixed?
For some Occurred Faults, sometimes you need to clear the fault, and run the watercraft again to
see if it is a current issue.
Step #4 - Clear the faults
To clear the faults, you simply press the Clear Faults button. The Faults will be cleared in the
modules
Step #5 - Run watercraft to verify problems are fixed
It is always advisable to run the watercraft again after fixing and clearing faults to ensure that all
problems are fixed. If you are running the watercraft while CANDooPro is connected, you can hit
the Refresh button at any time to check for new faults.

3.1.3 2 Stroke DI Models
NOTE: This section covers the Direct Injection models as follows:
2000 - GTX DI, RX DI
2001 - GTX DI, RX DI
2002 - GTX DI, RX DI, RX DI LE, LRV DI
2003 - GTX DI, RX DI, LRV DI, XP DI
2004 - XP DI
2006 - 3D DI
2007 - 3D DI
3.1.3.1 Connecting & starting a session
Connecting CANDooPro to a Direct Injection Watercraft:
The Direct Injection (DI) models all have a 6-pin Diagnostic Connector to attach the Candoopro
system.
WARNING: Do NOT use the Aluminum DESS adapter to connect to a DI!
152
CANDoo Professional
The 6-pin diagnostic connector is usually near the MPEM in the front storage compartment on GTX
DI, RX DI, LRV DI and 3D DI models, and in the very front of the engine near the hood hinge on the
XP DI models. It is a 6-pin Deutsch connector that has a special sealing cap on it, with a small
black "loopback wire". (the cap is a modified connector, usually gray with little white plugs in
the unused wire holes in the orange insulation of the connector.)
Disconnect the 6-pin connector from the sealing cap:
153
CANDoo Professional
NOTE: Always remember to put the cap back on the diagnostic connector
when you are finished with a Candoopro session! Otherwise your Maint
light will be on and stay on!
Steps for Starting a Candoopro session with the DI watercraft:
1. Plug the USB cord into the Candoopro box and the PC. The Green Power light on the
Candoopro box should light up.
2. Plug the 9 pin connector on the 9 pin/ 6-pin harness cable into the Candoopro box.
154
CANDoo Professional
3. Plug the 6 -pin connector on the 9-pin/6-pin harness cable into the diagnostic connector on the
PWC.
4. Start the Candoopro program. Upon launch, the program will show the following screen:
155
CANDoo Professional
Notice that when the program launches, it gives indication of the program connection status at the
lower left hand of the screen, as follows:


USB Connection Status indicates if the CANDooPro box is communicating to the computer
over the USB bus
o Green is connected
o Red is disconnected or not communicating
Vehicle Connection Status indicates if the CANDooPro system has detected or is
communicating with the vehicle
156
CANDoo Professional


o Green is detected or communicating
o Red indicates no vehicle is detected or is not communicating
Number of Connections indicates the total number of modules on the Vehicle that are
communicating with Candoopro system
o Zero indicates no modules are communicating
o One is typical for most Carburated, DI, and RFI vehicles (MPEM)
o Two is typical for early 4-tec models (ECU and MPEM)
o Three is typical for some later 4-tecs (ECU, MPEM, Cluster)
o Late model iS vehicles can have 5 modules communicating
Current Process shows the current activity
At this point, the CANDooPro program is looking for communication from the ski, and the
zero indicates that it does not have any communication with a ski.
5. Put a DESS key/lanyard on the DESS post on the ski. (Does not need to be programmed to the
ski; it can be any DESS key..) You should hear a single beep if the key has not been programmed
in memory, two beeps if the key has been programmed into the MPEM.
6. The CANDooPro program should detect the DI ski, the Vehicle Connection Status indicator
should change from red to green, and the Current Activity bar at the lower left should indicate "DI
Detected "
7. Select the Vehicle tab at top, select "Read Vehicle ", and the CANDooPro system should begin
to read the information from the MPEM.
8. Once the information is read from the MPEM, the main Vehicle screen should appear, and the
Current Activity bar at the bottom should alternate between "DI Detected" and "Real Time
Monitor". If you are using the Limited version of CANDooPro and this is the first time you have
connected to this watercraft, you will be prompted if you wish to have this watercraft count towards
your total available VIN numbers. Pressing Yes will add this watercraft to your list of VIN's used
You are now ready to begin a diagnostic session.

Overview
(See
3.1.3.2.3.2.2)
Overview:
The DESS keys/lanyards contain two distinct critical parts:


A powerful magnet
A microchip with a 64 bit serial number
The DESS post on the vehicle contains a reed switch, a center post, and a grounding ring around
the outside of the post. When a DESS key is inserted on the post, the magnet in the key closes the
reed switch in the DESS post. This "wakes up" the MPEM from hibernation, and the MPEM sends
out a signal on the center of the DESS post. Since the DESS key makes contact with the center
lug and the grounding ring, it sees this signal from the MPEM, and it sends its internal serial
number information to the MPEM. The MPEM compares this serial numbers to the serial numbers
contained in its internal list of keys.
If the serial number of the key matches one contained in the MPEM internal list of key serial
numbers, the MPEM gives the 2-beep signal and allows the operation of the vehicle. However, if
the serial number does not match, it gives the single long beep, and does not allow operation of the
vehicle.
The DI MPEM allows storing up to 8 key serial numbers in its list. CANDooPro allows you to
manage the list of keys, to add new keys up to a total of 8, and to erase keys.
The DI models have two main key operation profiles, Normal and Learning . (You can also
program Rental Keys, but they are basically the same as Learning )
Normal Keys allow full operation of the watercraft.
Learning/Rental keys limit the amount of speed to approximately 35 MPH, perfect for learning/first
time users (or that close friend or relative that always manages to ruin your stuff...)
Please note that ALL Sea Doo DESS lanyards are identical internally. They simply use a different
color float for the different function keys, (Normal Keys are Yellow, Learning Keys are White, Rental
Keys are Orange). You can use any kind of key for any purpose. For example, you can use a
White Learning key programmed as a Normal key, a Normal Key programmed as a Learning key,
etc.

176
CANDoo Professional
Often you will find that the key listing contains a number of keys that are no longer used. This can
happen over the years as keys are lost, and new keys are added without removing the old key
numbers. Candoopro makes it easy to remove these old unused key numbers.
To determine if your listing contains old, unused key numbers, simply test each key you have with
CANDooPro, write down the serial number of the key, and compare it to the ones in the list. You
can then remove any that are not currently needed.
To Erase a Key:
For any actions to be performed on keys, click on the far left column in the row for the particular key
you wish to delete. The entire row for that key must be completely highlighted in blue:
Once you have highlighted the key you wish to delete, simply click "Erase Selected Key", and the
selected key will disappear from the key listing:
Now that the key has been deleted, you must Write this change into the MPEM. Select "Vehicle" in
the upper tab, then "Write Vehicle".
177
CANDoo Professional
The CANDooPro program will write the information into the MPEM and read the information back
from the MPEM to ensure the information was written properly.
To Erase All Keys:
Pressing the "Erase All Keys" button will remove all keys from the listing.
Note that if you erase all keys, you must add back at least one key to the
listing before writing the change, otherwise unpredictable results may occur!
After you have added one or more keys to the listing, then you can write the change into the MPEM
with the Vehicle, Write Vehicle command.

Disabling DESS
The developers of CANDooPro have included an experimental feature to disable the DESS
function. The reason it is called "experimental" is because it doesn't always work, and appears to
render some early MPEM's useless. After turning a few early MPEM's into expensive
paperweights, we decided not to do a full listing of what MPEM's it works on, and which it doesn't.
We have had good success with 97 and newer MPEM's that are not installed inside the sealed
electric boxes.
Users of the CANDooPro system are strongly advised not to disable dess on your MPEM's unless
you accept the risk that it may become inoperable. We have successfully disabled DESS on a few
older MPEM's for the 717 engine, but have noticed that the procedure kills the MPEM's on the 9596 787 engines as well as the 98-99 787 engines installed in the X-4 hull (like SPX).
Disabling DESS:
In the Keys tab, select the Disable button. A box will warn you that you are about to perform a
risky operation.

Simply select Yes, and the write the information to the MPEM by selecting Vehicle and Write

Using features in the Settings tab:
In the DI Settings tab, you can do the following:


Reset the Throttle Position Sensor (TPS). The TPS must be reset anytime changes are
made to the throttle body on the DI watercraft, for example, if you replace the throttle body
or either throttle position sensor (DI throttle bodies have two TPS's). Please refer to the
Service Manual for more details about TPS.
Modify the Ignition Angle setting. The Ignition Angle setting should be checked anytime
the engine is rebuilt. Please refer to the Service Manual for more details, as the process to
check the current ignition angle setting is pretty complex. Please note that the procedure
in the Service Manual uses a very expensive angular Dial Indicator Gauge with a roller tip,
because the procedure in the manul uses the spark plug hole to mount the dial indicator,
which is inclined at an angle relative to the cylinder. While this is fairly easy since the
spark plugs are easy to remove, it is pretty dumb since virtually nobody is going to pay the
money to get the special roller tip dial indicator. Instead, you can remove the fuel injector
rail assembly and use a standard straight tipped dial indicator. Please note that while this
182
CANDoo Professional
method isn't in the description of the manual, you will find the proper value for using a
straight tipped dial indicator in the Specifications section.
Throttle Position Sensor Reset:
To change TPS setting:


Ensure that the throttle cable has slack, and that the throttle is against the idle stop screw.
Do not alter the throttle stop screw; just make sure the throttle is closed.
Press the Reset button in the Reset TPS section, and note that the throttle opening setting
is at zero.
Modify Ignition Angle setting:
NOTE: Please follow the instruction in the Service Manual for the watercraft you are
repairing for details on determining the proper ignition angle value. Note that
improper igntion angle can result in severe engine damage! The procedure in the manual
assumes using a special roller dial indicator. Refer to the notes at the top of this page
regarding the use of a standard dial indicator.
183
CANDoo Professional
To determine the Igntion Angle setting:
NOTE:The watercraft MUST BE RUNNING to check and change the igntion angle setting!



Once the engine is running , click the Lock (Disable Advance) button. This keeps the
advance from altering the base timing setting.
Using an appropriate timing light, check that the marks you scribed on the flywheel and the
pointer are in alignment.
If not, you will need to alter the timing angle
To Change the Igntion Angle setting:
Press the arrow in the white box to the left of the Set button, which will bring up a
drop down listing of igntion angle settings:
184
CANDoo Professional
Choose a value higher or lower than your current setting (depending upon the offset of the mark
from the pointer) and press Set.
Note the direction the mark has moved relative to the pointer, and if your change moved the mark
in the right direction. This will give you an idea if you are moving in the right direction and the
magnitude of how far off you are.
Try a setting in the proper direction, and continue until the marks align perfectly.
Once you have the proper setting, simply press the Unlock (enable advance) butting, and you are
done.

DI Faults and Diagnosis
The Direct Injection engines have a fairly powerful fault logging capability, but it has a number of
quirks that can be confusing. CANDooPro recommends that users carefully study the terms and
procedures outline in this section before using the system to diagnose faults. Please read the
Overview section before moving on to the Fault Diagnosis section.

DI Fault Overview
The DI Fault system is probably the least understood part of diagnosing and repairing DI
problems. In fact, many dealer technicians do not understand it, so the CANDooPro user is
encouraged to review the fault overview and diagnosis sections to better understand how to
interpret the information before trying to diagnose problems.
187
CANDoo Professional
Sea Doo introduced the Direct Injection system in 2000. In general, the DI's are pretty reliable,
start easily, and have excellent fuel economy. The downside of these watercraft is that they are
hard to work on, especially if you do not have a diagnostic system like CANDooPro. The DI MPEM
has a decent fault monitoring system, so if a problem occurs and the watercraft trips a fault that
results in the Maintenance light coming on, that fault is logged internally to enable you to zero in on
the problem that caused the fault to occur. More severe faults also cause the watercraft to go into
"Limp" mode; a reduced RPM situation to prevent engine damage.
Please note that there are a number of problems that can occur with DI's that do not cause a fault
to occur. For example, the DI system does not monitor Fuel or Air pressure. If either one of these
are not proper, the ski will not run right, but a fault may not be tripped in the MPEM. Additionally,
the Regulator/Rectifier on DI's are a well-known problem area. If the regulator does not put out the
proper voltage, there may or may not be a fault generated for the condition. An additional failure
mode is the regulator putting out an excessive amount of what is called "AC ripple". This will not
throw a fault, but the watercraft will not run over a certain RPM without misfiring.
The Fault Page
The fault page shows details of all of the possible 32 DI faults, as well as displaying information
about the first fault that was triggered after the faults and conditions were cleared.
First of all, let me say that the DI Fault detection and logging system is actually pretty simple and
straightforward, once you understand the terminology and how it works. It has some severe
limitations that add to the problem, but once you understand the limitations, you can easily put a
plan in place to get around the limitations.
188
CANDoo Professional
In the table above, please note that the first row of the table is not an actual fault, rather it is a total
snapshot of all faults combined.
Fault States
The DI Fault system has three fault states:



Inactive
Active
Occurred
Inactive Faults
"Inactive" means that a fault is not currently active, and has not been active since the ski has been
powered up
Active Faults
"Active" means that the fault is currently happening now; the underlying problem causing the fault
still exists and must be fixed.
Occurred Faults
"Occurred" means that a fault became active since the ski was powered up, but at this moment, it is
not active.
Fault State Examples
An example will help illustrate the fault states and how the fault states can confuse technicians that
don't undstand them fully. First, let me describe how the DI engine management system works in
the context of faults. The DI Engine Management System (EMS) uses input from a large number of
sensors to calculate the proper amount of fuel to inject as well as the ignition timing. If the EMS
loses a signal from a critical sensor, like the TPS for example, or gets input from the sensor that
doesn't make sense, it cannot compute the proper fuel to inject so it throws a fault, lights the Maint
light, and puts the ski into Limp Mode (reduced engine RPM capability).
Example 1:
You (or your customer) is riding the DI, and hits a wake. The connection to the Manifold Air
Pressure Sensor (MAPS) loses contact temporarily from the abrubt jarring when the ski hit the
wake. The EMS system senses this, throws a fault, ski goes into Limp Mode. Immediately after
the ski hits the bump, the connection to the MAPS is now good again, and the user rides the ski
back to the dock. At this time, the fault is not Active, but the ski is still in Limp mode. For this
particular fault, the ski must be shut off and restarted to resume normal operation. (most faults that
result in limp mode resume normal operation once fault cause goes away and the ski is returned to
idle, but a few (like MAPS or TPS) require the ski to be shut off and restarted)
Upon returning to shore, if you were to read the faults using Candoo before shutting off the ski , you
would notice that the fault shows to be Occurred. However, it is very rare that you would return to
shore, connect CANDooPro, and read the ski. Most of the time, ski is shut off, and the next time
you power it up and read the ski, the MAPS fault would show as inactive. Most DI faults are
189
CANDoo Professional
transient in nature, which means they happen, throw the ski into Limp Mode, and go away just as
fast as they happen. You (or your customer) bring the ski in to have it looked at, you read the ski,
and there are no active faults.
You see this often on the various Sea Doo forums. Someone posts they have a problem with the
ski going into limp mode, and they bring it into their local dealer, only to be told "there are no
faults". This is only partially true; there may not be any active faults, but there always is evidence
that a fault had happened before. It is all logged in the fault table.
Example 2:
Let's suppose that the rider in the above example hit the wake, and the connector actually fell off
the Exhaust Temperature Sensor. In this case, if you read the ski anytime after it happened, the
state of the ETS fault would be Active. In this example, you can quickly zero in on the problem and
fix it. Unfortunately, this type of problem is the exception rather than the rule. Most difficult
troubleshooting on the DI involves transient faults. They are not presently active, so how do you
figure out what it is? The answer is in the Count column.
The Count Column
Anytime a fault is triggered and the ski lights the Maint light and/or goes into Limp Mode, the fault is
logged in the Count column for that particular fault. This provides the evidence you need to zero in
on the problem. However, there is a major issue, a problem that makes it very difficult for the
typical dealer technician to zero in on the problem. The following screen illustrates the problem:
190
CANDoo Professional
As you can see, there are many faults with counts in the table above! This is very common to see;
many faults in the Count column, which have continued to build up over the years. Plus, the faults
have never been cleared since the ski was new! Please refer to the Fault Diagnosis for strategies
on how to zero in on recent faults.
The First Column
The First column is actually the first occurrence, in engine minutes, of a fault since the ski was new,
or since a fault has been cleared. In the example above, the faults have never been cleared. Take
a look at fault code P0562, Battery Voltage Low. The first time this ski had this fault, it happened
with only 21 minutes of engine time. Since that time, the fault has happened 21 times.
The Clear Column
The Clear column indicates the number of times that a particular fault has been cleared in the
past. The counter will only increment by one, and only if the fault is inactive and has a count.
The Last Column
The Last column indicates the last time a particular fault has been cleared, in engine minutes.
Please note that this is NOT the last time a fault has occurred!

Fault Diagnosis
As noted in the Overview Section, the DI engine management system logs the occurrence of faults
anytime they happen. The main problem with this system is that there is no way to tell which of the
many faults in the log are recent. I have personally read the MPEM's on many DI's, and every
single one had a large number of faults recorded in the fault table.
This section describes a strategy for zeroing in on a problem using the Fault logging capability
within the DI MPEM.
Step #1- Review the Fault data
191
CANDoo Professional
As described in the Overview, an Active fault means the problem is happening right now, an
Occurred fault means it has happened since the watercraft has been powered up, and Inactive
fault means the fault is not happening right now and has not happened since the watercraft has
been powered up.
Review the data in the fault table, and look first at the top line of the fault table. The first line is not
an actual fault; it is a total of all of the faults, so it gives you a quick snapshot of all faults. In the
example screenshot below, the fact that "Occurred" appears in the State column means that there
is an occurred fault on the watercraft. If there was an active fault, this cell in the table would set to
Active. The Count of 119 in the table means that there have been 119 instances of faults since the
faults were last reset. (in this case, since the watercraft was new) The "21" in the First column
means that the first instance of a fault happened at 21 minutes of engine operation. (If you look
down the list, you see that fault P0562, Battery Voltage Low, happened at 21 minutes of engine
operation. The battery was probably low from sitting when the watercraft was new, and triggered
the fault) Since the Clear and Last columns are at zero, this means the faults have never been
cleared.
NOTE: When you are reading faults, you will normally have an occurred fault for fault P1601
(Diagnostic Cap). This is OK, because the cap is not on during the diagnostic session with
CANDooPro. Please disregard this fault.
Step #2 - Fix any Active or Occurred faults
192
CANDoo Professional
Look in the table for any Active or Occurred faults. The underlying problem causing these faults
must be fixed. (Disregard the P1601 Diagnostic Cap fault) Refer to the Diagnostic Procedures
section of the Service Manual for the watercraft for instructions related to troubleshooting problems
related to the component(s) indicated by the fault.
Step #3 - Clear the faults
Most difficulties in diagnosing DI problems are related to Transient Faults. (a
Transient Fault happens briefly, then goes away) In the example presented in the Overview
Section, a transient fault is triggered by hitting a wake, then it immediately goes away. How do you
handle this type of situation? The solution is to clear the faults, and then run the watercraft again
until the fault happens again.
To clear the faults, you simply press the Clear Faults button. The Faults will be cleared in the
MPEM, and CANDooPro will display an updated table once the faults are cleared.
The Fault Clearing process does the following:





Resets the Count column to zero for any faults that have a count value
Resets the First column to zero for all faults
For any faults that have a count, the Clear column will increment up by one. For example,
if you show a count value of 10 for a particular fault, and a Clear value of 2, after clearing,
the count value will be set to 0, and the Clear value will be set to 3.
For any faults that have a count, the Last column will be set to the current engine hours, in
minutes. For example, if you have a P0563 faut with a count, and your present engine
hours are 95 Hours, 24 minutes, the Last cell for that fault will be set to 5604.
Resets the Conditions table to blank.
Step #4 - Run watercraft until fault reappears
Although this step is hard for an independent shop, (because you need to tell the customer to run it
again until fault happens again and bring it back) it is something that makes CANDooPro very
valuable for the DI owner. You can clear the faults and go out and run it until the fault comes back.
Step #5 - Read faults again
Once you have cleared the faults and run the watercraft again until the fault reappears, you have
everything you need to determine what caused the fault. The DI MPEM logs every fault by
incrementing the Count by one anytime the fault appears. For example, you have cleared the
faults, you take the watercraft out for a run, and when you hit a wake, the watercraft displays Maint
and it goes into limp mode. You take the watercraft back to the dock, shut off the watercraft, and
attach CANDooPro and read the fault table. All faults show Inactive (except the Diagnostic Cap
fault). However, when you look at the Count table, you notice that only one fault has a Count (of 1)
and it is fault P0475 RAVE Solenoid. You now know for sure that the fault that caused the limp
mode and Maint light was something related to the Rave solenoid. In this example, it could be the
RAVE solenoid is faulty, but it is more likely that the wiring or connector to the RAVE solenoid is
making a bad connection when a bump was hit.
193
CANDoo Professional
Additionally, please note that the large box below the fault table is called the First Fault Conditions.
After you clear the faults, when a new fault is logged, the very first fault that is logged will have a
set of data logged with it. This is helpful for diagnosing problems that are not necessarily related to
a component that creates the fault (such as high temperature), but may be related to other engine
conditions or how it is being operated.
Step #6- Fix the problem
In the examples cited above, you can see that by using the above strategy, you can easily zero in
on what transient problems have happened. You can now refer to the Diagnostic Procedures
section of the Service Manual for the watercraft for instructions related to troubleshooting problems
related to the component(s) indicated by the fault with the Count value, as well as the First Fault
Conditions logged with the first fault logged after the clearing of the faults.

3.1.4.2 Connecting & starting a session
Connecting CANDooPro to a 4-TEC Watercraft:
The 4-TEC models all have a 6-pin Diagnostic Connector to attach the Candoopro system.
Warning: Do NOT use the Aluminum DESS adapter cable to connect to a 4TEC watercraft!
The 6-pin diagnostic connector is usually in the front storage compartment on 2002 to 2012 2seater models (e.g. RXP) without the iS control system, in the engine bay near the battery on the
2002 to 2012 3-seater models (e.g. GTX. GTI, RXT) without the iS control system, and is in the
rear compartment on late models with the iControl system, near the battery. It is a 6-pin gray
Deutsch connector that has a special sealing cap on it.
216
CANDoo Professional
Disconnect the 6-pin connector from the sealing cap:
217
CANDoo Professional
Warning: Always remember to put the cap back on the diagnostic connector
when you are finished with a Candoopro session! Otherwise your Maint
light will turn on and stay on!
Steps for Starting a Candoopro session with the 4_TEC watercraft:
1. Plug the USB cord into the Candoopro box and the PC. The Green Power light on the
Candoopro box should light up.
2. Plug the 9 pin connector on the 9 pin/ 6-pin harness cable into the Candoopro box.
218
CANDoo Professional
3. Plug the 6 -pin connector on the 9-pin/6-pin harness cable into the diagnostic connector on the
PWC.
4. Start the Candoopro program. Upon launch, the program will show the following screen:
219
CANDoo Professional
Notice that when the program launches, it gives indication of the program connection status at the
lower left hand of the screen, as follows:


USB Connection Status indicates if the CANDooPro box is communicating to the computer
over the USB bus
o Green is connected
o Red is disconnected or not communicating
Vehicle Connection Status indicates if the CANDooPro system has detected or is
communicating with the vehicle
o
Green is detected or communicating
220
CANDoo Professional


o Red indicates no vehicle is detected or is not communicating
Number of Connections indicates the total number of modules on the Vehicle that are
communicating with Candoopro system
o Zero indicates no modules are communicating
o One is typical for most Carburated, DI, and RFI vehicles (MPEM)
o Two is typical for early 4-tec models (ECU and MPEM)
o Three is typical for some later 4-tecs (ECU, MPEM, Cluster)
o Late model iS vehicles can have 5 modules communicating
Current Process shows the current activity
At this point, the CANDooPro program is looking for communication from the ski, and the
zero indicates that it does not have any communication with a ski.
5. Put a DESS key/lanyard on the DESS post on the ski. (Does not need to be programmed to the
ski; it can be any DESS key..) You should hear a single beep if the key has not been programmed
in memory, two beeps if the key has been programmed into the ECU
6. The CANDooPro program should detect the 4-TEC ski, the Vehicle Connection Status
indicator should change from red to green, and the Current Activity bar at the lower left should
indicate "CAN Detected" as well as the speed that it is communicating (2002-2010 models without
iControl connect at 250K, late iControl models communicate at 500K)
7. Select the Vehicle tab at top, select "Read Vehicle ", and the CANDooPro system should begin
to read the information from the modules (MPEM, ECU, Cluster) on the ski
8. Once the information is read from the modules, the main Vehicle page should appear. If you
are using the Limited version of CANDooPro and this is the first time you have connected to this
watercraft, you will be prompted if you wish to have this watercraft count towards your total
available VIN numbers. Pressing Yes will add this watercraft to your list of VIN's used. You are
now ready to begin a diagnostic session.
221
CANDoo Professional
3.1.4.3 Working with CANDooPro
The subjects contained in this section describes the process for
working with 4-TEC data using the CANDooPro system.
In general, you must go thru the following steps to change or modify information in the 4-TEC
modules.
1. Read the modules on the watercraft, using the Read Vehicle command contained in the
Vehicle tab of the program
2. Modify the information (for example, reset service hours, add new key, etc)
3. Write the changes back to the MPEM, using the Write Vehicle command contained in the
Vehicle tab of the program:
4. Some changes on the 4-TEC are instantaneous, for example, clearing faults. These changes do
not need to be written to the modules using the Write Vehicle command.
3.1.4.3.1 Resetting Maintenance Light
Resetting the Maintenance Light
There are two causes for the Maintenance Light to be blinking on a 4-TEC
1. The internal Service Interval counter indicates that the watercraft is due for maintenance. (It is
simply a Maintenance reminder light)
2. The 4-TEC Engine Management System detects an active fault.
It is recommended that anytime the Maintenance light is blinking to try resetting the Maintenance
Reminder light first.
To turn off the Maintenance Reminder light:
The Maintenance Reminder light is turned off by resetting the "Last Service" counter on the main
Vehicle tab. See the Vehicle Tab for more information
To turn off the Maintenance light due to faults:
If the 4-TEC Engine Management System detects an Active Fault, it will indicate this condition on
the cluster. The Active Fault must be fixed to turn off the blinking light. Please refer to the
procedures outlined in the 4-TEC Faults Tab section to diagnose which fault is active, and correct
the problem associated with that fault.

Overview
(See
3.1.4.3.2.2)
(See
3.1.4.3.2.2.2)
Overview:
The DESS keys/lanyards contain two distinct critical parts:


A powerful magnet
A microchip with a 64 bit serial number
The DESS post on the vehicle contains a reed switch, a center post, and a grounding ring around
the outside of the post. When a DESS key is inserted on the post, the magnet in the key closes the
reed switch in the DESS post. This "wakes up" the ECU from hibernation, and the ECU sends out
a signal on the center of the DESS post. Since the DESS key makes contact with the center lug
and the grounding ring, it sees this signal from the ECU, and it sends its internal serial number
information to the ECU. The ECU compares this serial numbers to the serial numbers contained in
its internal list of keys.
If the serial number of the key matches one contained in the ECU internal list of key serial
numbers, the ECU gives the 2-beep signal and allows the operation of the vehicle. However, if the
serial number does not match, it gives the single long beep, and does not allow operation of the
vehicle.
The 4-TEC ECU allows storing up to 8 key serial numbers in its list. CANDooPro allows you to
manage the list of keys, to add new keys up to a total of 8, and to erase keys.
The 4-TEC models have two main key operation profiles, Normal and Learning . (You can also
program Rental Keys on the 2007+ GTI Rental PWC )
Normal Keys allow full operation of the watercraft.
Learning keys limit the amount of speed to approximately 35 MPH, perfect for learning/first time
users (or that close friend or relative that always manages to ruin your stuff...)
225
CANDoo Professional
Rental Keys limit the speed to approximately 45 MPH.
Please note that ALL Sea Doo DESS lanyards are identical internally. They simply use a different
color float for the different function keys, (Normal Keys are Yellow, Learning Keys are White, Rental
Keys are Orange). You can use any kind of key for any purpose. For example, you can use a
White Learning key programmed as a Normal key, a Normal Key programmed as a Learning key,
etc.

Testing Keys:
To test if the microchip in the key is good, you can use the Test Key function of candoo.
To test a key:

Insert the key you wish to test on the DESS post mounted to the CANDooPro box
226
CANDoo Professional

At the top toolbar, selet Key and then click Test Key as shown below:
If the microchip in the key is working properly, you will see the popup box similar to the one shown
below :
227
CANDoo Professional
The key number shown by the popup box is the 64 bit serial number of the key. (Shown in
Hexidecimal format) Note that this only tests the microchip in the key; it does not check for a weak
magnet.
If you receive a pop up box stating " Key Not Found",try repositioning the key again on the post. If
you still receive the "Key Not Found" message after repeated trys, remove key, clean the stainless
metal contacts on the key with a pencil eraser and try again. If it still will not read, the key is likely
no good.

Erasing Keys
(See
3.1.4.3.2.2.2)
(See
3.1.4.3.2.2.4)
Erasing Keys:
Often you will find that the key listing contains a number of keys that are no longer used. This can
happen over the years as keys are lost, and new keys are added without removing the old key
numbers. Candoopro makes it easy to remove these old unused key numbers.
228
CANDoo Professional
To determine if your listing contains old, unused key numbers, simply test each key you have with
CANDooPro, write down the serial number of the key, and compare it to the ones in the list. You
can then remove any that are not currently needed.
To Erase a Key:
For any actions to be performed on keys, click on the far left column in the row for the particular key
you wish to delete. The entire row for that key must be completely highlighted in blue:
Once you have highlighted the key you wish to delete, simply click "Erase Selected Key", and the
selected key will disappear from the key listing:
Now that the key has been deleted, you must Write this change into the MPEM. Select "Vehicle" in
the upper tab, then "Write Vehicle".
229
CANDoo Professional
After you select Write, a popup box will instruct you to remove the key and wait until the connect
light is off to complete the write operation. (a box will not popup on 2009 and newer models with
the iControl system; you do not need to remove the key on these models) Follow the instructions in
the box, and especially take note that on 2007 and newer models, you need to take the key off, put
it back on, then remove again to complete the write operation.
To Erase All Keys:
Pressing the "Erase All Keys" button will remove all keys from the listing.
Note that if you erase all keys, you must add back at least one key to the
listing before writing the change, otherwise unpredictable results may occur!
230
CANDoo Professional
After you have added one or more keys to the listing, then you can write the change into the MPEM
with the Vehicle, Write Vehicle command.

(See
3.1.4.3.2.2.3)
(See
3.1.4.3.2.2.5)
Adding Keys:
The ECU can store up to 8 keys. To add a new key, you must have an available key slot (empty
row) in the key chart. If the chart has all 8 keys filled, you must erase a key before CANDooPro will
allow you to add a new key.
To Add a new Key:
Insert the key you wish to add to the ECU onto the post on the CANDooPro interface box. Ensure
the key is pushed all the way down onto the post and is square on the post.
231
CANDoo Professional
Once the key is on the post, click the type of key you wish to add. For example to add a normal
key, click the "Add Normal Key" button. A box will appear indicating the key has been added to
the key listing.
NOTE: If a key is not on the post, is not properly seated on the post, or is not
a good key, you will see an error message "Key Not Found".
Once you have added the key to the list, you must now write the new key into the MPEM. Select
"Vehicle" in the upper tab, then "Write Vehicle".
232
CANDoo Professional
After you select Write, a popup box will instruct you to remove the key and wait until the connect
light is off to complete the write operation. (a box will not popup on 2009 and newer models with

Disabling DESS
The developers of CANDooPro have included an experimental feature to disable the DESS
function. The reason it is called "experimental" is because it doesn't always work, and appears to
render some early MPEM's useless. After turning a few early MPEM's into expensive
paperweights, we decided not to do a full listing of what MPEM's it works on, and which it doesn't.
We have had good success with 97 and newer MPEM's that are not installed inside the sealed
electric boxes.
233
CANDoo Professional
We strongly advise not to try disabling DESS on 4-TEC watercraft


Always refer to your Service Manual for the proper instructions for your watercraft. In
general, ensure that the throttle cable has slack, and that the throttle is closed against the
idle stop screw, by opening and closing the throttle several times. Do not alter the throttle
stop screw setting!; just make sure the throttle is closed.
When the Settings page is first accessed, the TPS setting will not be displayed, because
the monitor function that detects the TPS setting is not running. Press the Start Monitor
button to observe the TPS reading.
The TPS reading should be zero. If not zero, then you should reset the TPS.
Press the Reset button in the Reset TPS section.
A popup box will appear to instruct you to remove the key to complete the TPS setting
operation. Follow the instructions in the popup box.
After you remove the key per the instructions, you can put the key back on and ensure that
the TPS setting is zero.
To Reset Throttle Position Sensor (TPS) on 2009+ models with Bosch ECU
(iControl watercraft):




Always refer to your Service Manual for the proper instructions for your watercraft.
The idle speed on this model is controlled actively by the electronic throttle body, so the
throttle butterfly is always open sufficiently to allow proper idle.
The TPS value on this model will never be zero after reset; typically it will show a value
around 9-10.
A pop-up box will not show after you reset the TPS, as this is done actively by the ECU,
and you do not need to Write the ECU to store the new value.

To Change MPEM/ECU Options on Siemens ECU models :
NOTE: The options selected must match the options you have on your watercraft. Check your
wiring diagram and watercraft carefully to ensure that you have all the proper options selected. It
has been observed that these watercraft "lose" their options settings for no apparent reason (it is
speculated that it happens if the battery is disconnected or low for a long period of time). If the
options selected do not match what is installed on the watercraft, the option will not work properly
and may trigger a fault. NOTE: Bosch ECU models automatically determine the proper settings,
there will be no check boxes on these models.




For each option present on the watercraft, ensure that a check mark is in the box next to
the option.
If an option is present but there is no checkbox, simply check the box next to the option.
If an option is not present on the watercraft, but there is a check in the box next to the
option, click on the box to remove the check mark
Any changes need to be written to the ECU. Select Vehicle and Write Vehicle.
After you select Write, a popup box will instruct you to remove the key and wait until the connect
light is off to complete the write operation. (a box will not popup on 2009 and newer models with
the iControl system; you do not need to remove the key on these models) Follow the instructions in
the box, and especially take note that on 2007 and newer models, you need to take the key off, put
it back on, then remove again to complete the write operation.

Marrying Clusters :
Starting in 2006, Sea Doo implemented a security feature to require matching, or marrying the
cluster to the ECU, since the cluster reports running hours. (To prevent the user from putting on a
cluster with low hours). The ski will not start if you put a new cluster on these models, and you
must marry the cluster to the ECU.
To marry the cluster:




Read the vehicle, and go to the Settings tab
A section indicating "new cluster detected, do you want to marry it?" will appear.
Check the box, and Write the vehicle. The new cluster will now be married to the ECU
Make sure the ski starts, if not, check to see if the message appears in the settings tab and
try again.
Warning: Starting in 2008, BRP began selling clusters with no internal profiling software in them.
These replacement clusters are for 2006-2012 models. The appropriate software must be loaded
into them before they will work properly. This is done with the BUDS dealer software. CANDooPro
will not load this software, as it is the copyrighted property of BRP

Overview
(See
3.1.4.3.2.4)
(See
3.1.4.3.2.4.2)
Fault Overview
The 4-TEC Engine Management System continually checks the various components in the system
for proper operation. If it detects a problem with any component in the system, it will create an
active fault related to the problem. Anytime this happens, the system logs these faults within the
fault table. For many of these faults, it also logs a range of engine operating conditions. Note that
not all faults are stored. Some faults, once fixed, have no record in the fault table.
The Fault Page:
The 4-TEC fault system displays data associated with faults that have been logged since the last
time the faults have been cleared. For any faults listed in the box on the left side, simply click on
the fault code number to have the page display the information associated with the fault code.
Many, but not all faults will have information stored with the fault that will assist in troubleshooting
the problem associated with the fault.
238
CANDoo Professional
Fault Code:
The fault codes are special codes assigned to particular problems. More information about the
fault codes can be found in the Service Manual.
Source:
The Source tells you which component is sensing the problem.
Status
The 4-TEC Fault system has two fault states:


Active
Occurred
Active Faults
"Active" means that the fault is currently happening now; the underlying problem causing the fault
still exists and must be fixed.
Occurred Faults
"Occurred" means that a fault became active at some time in the past, but at this moment, it is not
active.
239
CANDoo Professional
Count
The first time the system detects a fault, it adds the fault to the list (if not already there), and
increments the fault counter by one. Note that it only adds one per each time the system has been
powered up. For example, it may detect a fault 20 times during a ride, but it only adds one to the
count during the entire time the watercraft has been running. Next time the watercraft is powered
up and has the fault, it will add one more to the counter. Note that not all faults will have a count.
Hours:
The system logs the engine hours when the fault first occurred.

3.1.4.3.2.4.1)
(See
3.1.4.3.2.5)
4-TEC Fault Diagnosis
The Fault page gives you details about faults logged by the various modules (MPEM, ECU, Cluster,
etc) The following steps can be used to diagnose issues by reviewing the fault data.
Step #1- Review the Fault data
As described in the Overview, an Active fault means the problem is present now, and an Occurred
fault means it has happened some time in the past.
Review the data in the fault table, and review each fault listed in the box on the left hand side by
clicking each fault and reviewing the data associated with the fault.
NOTE: When you are reading faults, you will often have occurred faults for faults P600 and
P1680. These two faults often occur simply because of the way CANDooPro detects the
watercraft. You can usually disregard these faults, but ensure that you do not have an
active fault for either one. This could indicate a bad MPEM or ECU.
240
CANDoo Professional
Step #2 - Fix any Active Faults
Look in the table for any Active faults. The underlying problem causing these faults must be
fixed. Refer to the Diagnostic Procedures section of the Service Manual for the watercraft for
instructions related to troubleshooting problems related to the component(s) indicated by the fault.
Step #3- Analyze the Occurred Faults
Understanding Occurred Faults can be tricky. While transient problems (those that happen briefly
and then go away) will log an occurred fault, not all faults are stored by the system, so when you
shut off the watercraft, the fault is lost. Additionally, if faults have not been cleared for
quite awhile, you may not have a good indication if an occurred fault in the table is still a problem.
For example, you or a customer may notice a fault occur while running the watercraft. Let's say the
Exhaust Temperature Sensor has a bad connector that randomly disconnects. The watercraft may
signal a fault, but this particular fault is not stored. It will show Occurred while the watercraft is
running, but when you shut it off and restart, it may not be present if the connection is OK when you
start.
Or let's say you notice an Occurred P0122 TPS fault, with a count of 3. When did this happen? Is
it still an issue that needs to be fixed?
241
CANDoo Professional
For some Occurred Faults, sometimes you need to clear the fault, and run the watercraft again to
see if it is a current issue.
Step #4 - Clear the faults
To clear the faults, you simply press the Clear Faults button. The Faults will be cleared in the
modules
Step #5 - Run watercraft to verify problems are fixed
It is always advisable to run the watercraft again after fixing and clearing faults to ensure that all
problems are fixed. If you are running the watercraft while CANDooPro is connected, you can hit
the Refresh button at any time to check for new faults.

3.2.2 Connecting & Starting a session
NOTE: Yamaha Waverunners do NOT have a dedicated Diagnostic
Port! Please read instructions below how to connect the diagnostic
system!
Vehicle Connection:
255
CANDoo Professional
NOTE: Before connecting to a ski, please read the service manual for the particular
model of Waverunner!
In general, starting a diagnostic session involves two steps:
1. Connecting the Candoopro system to the Waverunner diagnostic connector
“ Waking up” the engine ECU to enable the Candoopro system to talk to the ECU
2.
Connecting the Diagnostic Cable to the Waverunner:
Some Yamaha engines (like the outboard motors) have a dedicated 3-pin diagnostic
connector , butWaverunners do not have a dedicated diagnostic connector. The
gauges/clusters onWaverunners “ speak” to the ECU in the same way that their
diagnostics tools communicate with the ECU, so YamahaWaverunners have a standard 3pin connector in the front storage area that is used to communicate information to the
cluster during normal ski operation, and is used for the diagnostic tool (Candoopro
diagnostic system) for a diagnostic session.
Steps to connect:
1. Locate the 3-pin cluster/diagnostic connector in the front storage
compartment of the ski. You may need to open an access panel on some
models to get to the connector. The connector is a three-pin dark gray
connector:
256
CANDoo Professional
Disconnect this connector, and plug the Candoopro Yamaha adapter cable light gray connector
into the mating connector on theWaverunner harness:
2.
257
CANDoo Professional
3. You are now ready to “wake up” the ECU and start a diagnostic session.
Waking up the ECU:
In order to initiate a diagnostic session, you need to “ wake up” or turn on the ECU. This
is done by starting the ski. ( or attempting to start the ski if it will not run!)
1. Start the Waverunner engine. If you wish to do an active diagnostic session
while the engine is running (for example, using the engine monitor function,
or to drop a cylinder while running) please follow the instructions and
warnings in the service manual for this vehicle, and make sure you supply
cooling water to the engine per the service manual.
2. If you do not wish to run the engine while doing diagnostics (for example, to
read and clear faults) you can just start the ski, start the diagnostic session
with Candoopro, and shut off the engine. Once the ski is in diagnostic
mode, the ECU should continue to stay active. (if it should happened to
shut down, just restart the ski and start the diagnostic session over)
Starting the Diagnostic Session:
When the Candoopro application is running, and the ECU has been woken up, you are
ready to start the diagnostic session.
258
CANDoo Professional
Once the ECU is woken up, the Candoopro application should detect the Yamaha ECU,
indicated by the ski icon on the lower left of the screen changing from red to green, and
the status should change from “ Looking for Vehicle” , to “ Yamaha Detected” .
Once “ Yamaha Detected” appears, go to the upper left of the screen, select “ Vehicle” ,
then “ Read Vehicle” .
The Candoopro system will read the data from the ECU. You are now ready to read and
clear faults, view operating history, activate various functions available for that particular
model.

3.2.3.2 Faults Tab
Please refer to each section below for more details about Faults and
diagnosis
3.2.3.2.1 Overview
Fault Overview
The Yamaha ECU continually checks the various components in the system for proper operation.
If it detects a problem with any component in the system, it will create an active fault related to the
problem. Anytime this happens, the system logs these faults within the fault table. For many of
these faults, it also logs a range of engine operating conditions. Note that not all faults are stored.
Some faults, once fixed, have no record in the fault table.
The Fault Page:
The Yamaha fault system displays faults that have been logged since the last time the faults have
been cleared. For any faults listed in the box on the left side, simply click on the fault code number
to have the page display the information associated with the fault code.
260
CANDoo Professional
Fault Code:
The fault codes are special codes assigned to particular problems. More information about the
fault codes can be found in the Service Manual.
Source:
The Source tells you which component is sensing the problem.
Status
The Yamaha Fault system has two fault states:


Active
Occurred
Active Faults
"Active" means that the fault is currently happening now; the underlying problem causing the fault
still exists and must be fixed.
Occurred Faults
"Occurred" means that a fault became active at some time in the past, but at this moment, it is not
active.
Hours:
The system logs the engine hours when the fault first occurred.

3.2.3.2.2 Fault Diagnosis
Yamaha Fault Diagnosis
The Fault page gives you details about faults logged by the ECU. The following steps can be used
to diagnose problems.
Step #1- Review the Fault data
As described in the Overview, an Active fault means the problem is present now, and an Occurred
fault means it has happened some time in the past.
Review the fault information by clicking the fault number in the listing on the left side of the page
Step #2 - Fix any Active Faults
Look in the table for any Active faults. The underlying problem causing these faults must be
fixed. Refer to the Diagnostic Procedures section of the Service Manual for the watercraft for
instructions related to troubleshooting problems related to the component(s) indicated by the fault.
Step #3- Analyze the Occurred Faults
Understanding Occurred Faults can be tricky. While transient problems (those that happen briefly
and then go away) will log an occurred fault, not all faults are stored by the system, so when you
shut off the watercraft, the fault is lost. Additionally, if faults have not been cleared for
quite awhile, you may not have a good indication if an occurred fault in the table is still a problem.
For example, you or a customer may notice a fault occur while running the watercraft. Let's say the
Exhaust Temperature Sensor has a bad connector that randomly disconnects. The watercraft may
signal a fault, but this particular fault is not stored. It will show Occurred while the watercraft is
262
CANDoo Professional
running, but when you shut it off and restart, it may not be present if the connection is OK when you
start.
For some Occurred Faults, sometimes you need to clear the fault, and run the watercraft again to
see if it is a current issue.
Step #4 - Clear the faults
To clear the occurred faults, you first press the Clear Faults button. The Faults will be cleared in
the ECU. Then you must power off the vehicle, and re-start the CANDooPro diagnostic session for
the fault to disappear from stored status.
Step #5 - Run watercraft to verify problems are fixed
It is always advisable to run the watercraft again after fixing and clearing faults to ensure that all
problems are fixed. If you are running the watercraft while CANDooPro is connected, you can hit
the Refresh button at any time to check for new faults.
3.2.3.3 Monitor Tab
The Engine Monitor tab:
The Engine Monitor feature allows you to monitor several engine parameters, primarily for
observing sensor readings while engine is stationary, and then while running.
Also note that you can use the engine monitor for checking the operation of the TPS, by moving the

Fault Overview
273
CANDoo Professional
The Kawasaki DI EMM continually checks the various components in the system for proper
operation. If it detects a problem with any component in the system, it will create an active fault
related to the problem. Anytime this happens, the system logs these faults within the fault table.
For many of these faults, it also logs a range of engine operating conditions. Note that not all faults
are stored. Some faults, once fixed, have no record in the fault table.
The Fault Page:
The Kawasaki DI fault system displays faults that have been logged since the last time the faults
have been cleared. For any faults listed in the box on the left side, simply click on the fault code
number to have the page display the information associated with the fault code.
Fault Code:
The fault codes are special codes assigned to particular problems. More information about the
fault codes can be found in the Service Manual.
Source:
274
CANDoo Professional
The Source tells you which component is sensing the problem.
Status
The Kawasaki DI Fault system has two fault states:


Active
Occurred

Active Faults
"Active" means that the fault is currently happening now; the underlying problem causing the fault
still exists and must be fixed.
Occurred Faults
"Occurred" means that a fault became active at some time in the past, but at this moment, it is not
active.
Priority
The Kawasaki DI system has three priority states for faults:
"A" faults are the most severe case, and can result in engine damage if continued to run
"B" faults are the second level of faults, and are not as severe, and may result in improper
operation
"C" faults are the least severe level of faults, and generally do not result in any
275
CANDoo Professional
Limp
This indicates whether the fault puts the ski into Limp mode
Warning
Some faults activate warning signals, such as the Check Engine light. This field
indicates what warnings are given with the fault.

Kawasaki DI Fault Diagnosis
The Fault page gives you details about faults logged by the ECU. The following steps can be used
to diagnose problems.
Step #1- Review the Fault data
As described in the Overview, an Active fault means the problem is present now, and an Occurred
fault means it has happened some time in the past.
Review the fault information by clicking the fault number in the listing on the left side of the page
276
CANDoo Professional
Step #2 - Fix any Active Faults
Look in the table for any Active faults. The underlying problem causing these faults must be
fixed. Refer to the Diagnostic Procedures section of the Service Manual for the watercraft for
instructions related to troubleshooting problems related to the component(s) indicated by the fault.
Step #3- Analyze the Occurred Faults
Understanding Occurred Faults can be tricky. While transient problems (those that happen briefly
and then go away) will log an occurred fault, not all faults are stored by the system, so when you
shut off the watercraft, the fault is lost. Additionally, if faults have not been cleared for
quite awhile, you may not have a good indication if an occurred fault in the table is still a problem.
For example, you or a customer may notice a fault occur while running the watercraft. Let's say the
Exhaust Temperature Sensor has a bad connector that randomly disconnects. The watercraft may
signal a fault, but this particular fault is not stored. It will show Occurred while the watercraft is
running, but when you shut it off and restart, it may not be present if the connection is OK when you
start.
For some Occurred Faults, sometimes you need to clear the fault, and run the watercraft again to
see if it is a current issue.
277
CANDoo Professional
Step #4 - Clear the faults
To clear the occurred faults, you first press the Clear Faults button. The Faults will be cleared in
the ECU. Then you must power off the vehicle, and re-start the CANDooPro diagnostic session for
the fault to disappear from stored status.
Step #5 - Run watercraft to verify problems are fixed
It is always advisable to run the watercraft again after fixing and clearing faults to ensure that all
problems are fixed. If you are running the watercraft while CANDooPro is connected, you can hit
the Refresh button at any time to check for new faults.

Kawasaki 2007+ Ultra 250X/260X/300X/LX Fault History
The Kawasaki 2007+ Ultra 250X/260X/300X/LX models have fault storing/ logging capability that is
quite different from the earlier models. The basic concept is when a fault occurs, it stores this fault
in the history table, along with a large number of operating parameters. This is a pretty powerful
feature that is helpful for capturing transient (intermittent) faults, that are hard to replicate.
However, there are a number of quirks with this system:




Not all faults that occur get captured in the History table. There is no good guide to what
faults get stored, and which do not.
A maximum of 3 faults can be stored in the History table. If a particular fault happens
repeatedly, it will store the same fault repeatedly in all three positions.
The Kawasaki ECU's do not store running hour information. Therefore, they cannot track
when a fault occurs. Is it a recent fault in the History table? Did it happen many hours
ago?
Kawasaki did not give any method of clearing faults. They are always stored, until a new
fault occurs and overwrite old faults in the table.

Activate Features:
The Activate page allows you to dynamically test a number of components to simplify
troubleshooting
NOTE: Most of the activate features on the 2007+ Ultra 250X/260X/300X/LX models are used
while the engine is running!
Description of Activate Features:



The Disable Injector and Disable Ignition Coil buttons shut off the fuel and ignition to
the selected cylinder while the engine is running. Pressing the selected cylinder should
cause the engine to run roughly and slow down slightly. Each cylinder should affect the
overall running by the same relative amount.
The ISC Valve button moves the idle valve in and out to check that the valve is
operational. The engine speed should vary when this button is pressed
The Fuel Pump button operates the fuel pump only while the engine is off.
