Vehicle Connection & Diagnostics
Connecting the SCANNER to the Vehicle
This section of the manual gives you drawings of the vehicle diagnostic
connectors and tells you which SCANNER adaptor to use. The
carmakers are listed alphabetically for quick-reference.
After you identify the vehicle, the SCANNER display then tells you where
to find the diagnostic connector and which vehicle adaptor to use.
CAUTION: Ensure vehicle identification as entered on the screen is
same as the vehicle connected to the SCANNER. Ensure SCANNER
adaptor is connected to correct vehicle pins as failure to observe above
can damage the diagnostic equipment and the cost of repairs is not
covered by warranty.
Note on Functional Tests
Functional tests are not applicable to Ethos software.
Important Information on Graph Mode
Note that not all vehicle systems will be able to be displayed in the
Graph Mode due to the communication type. It may also take several
attempts to establish communication in Graph Mode. This is not a fault
of the scan tool or vehicle.

CODES ONLY
This test menu heading is for displaying the ECU codes. When selected
the SCANNER will request codes from the Engine ECU.
Any codes displayed may be either currently active or may have been
previously set.
When these codes are displayed only the codes set in the ECU are
displayed on screen.
When a code is transmitted by the vehicle to the SCANNER the code
will indicate there may be problem either in the WIRING between the
ECU and the indicated sensor/actuator or in the indicated sensor/
actuator.
These codes can be cleared by selecting CLEAR CODES from the
SCANNER exit menu. See Clear Codes later in this section.
DATA ONLY
This test menu selection will display ECU live data only (no codes will
be displayed). Some parameters may show a value when the engine
is not running for example RPM, this is a normal function and does not
indicate a fault in the vehicle or SCANNER. When the vehicle is running
the value should read correctly.
See the Parameter Listing section in this Manual for descriptions and
explanations of the parameters.
NOTE: For Leganza vehicles fitted with the 2.2L engine refer to the
OBD-II and EOBD Vehicle Communication Manual for engine testing
information.
Clear Codes
Clear codes are usually available on the data list exit menu for all
Daewoo engines but if not displayed then remove a battery terminal for
a period of at least 1 minute.
NOTE: When removing battery terminals it is good practice to check
radio stations settings and for security system operation prior to terminal
removal.

Daewoo
Daewoo – Automatic Transmissions
Codes & Data
The SCANNER will display automatic transmission data and any
automatic transmission codes transmitted by the vehicle on the screen.
Any codes present are displayed at the top of the on-screen data list,
if there are no codes present the SCANNER will display (NO CODES
PRESENT).
The SCANNER can display “CURRENT CODES” or “HISTORICAL
CODES” for the automatic transmissions except for the Espero
automatic transmission.
Current Codes, or hard codes, are codes that are present at the time of
testing - the fault is still there. Historical Codes, or soft codes, are codes
that have been registered in the past but are not present at the time of
testing – either the code has been set by an intermittent fault or was
repaired previously and the code not cleared.
Current codes are displayed first and Historical codes second.
Espero Only Notes
Codes & Data communication with the Espero auto trans takes longer to
establish than other model Daewoo’s, this is a characteristic of the TCM
(Transmission Control Module) communication type and is not indicative
of a problem with the vehicle or the SCANNER.
The Espero transmission does not distinguish between a current code
and a historical code. While the SCANNER is communicating with the
Espero if a code is set the SCANNER will not beep.
NOTE: When a code is transmitted by the vehicle to the SCANNER
the code will indicate there may be a problem either in the WIRING
between the ECU and the indicated sensor/actuator or in the
indicated sensor/actuator.

There are various tests available under this menu option, including
Injector tests, Purge solenoid valve tests, Fuel Pump test and Idle speed
actuator tests. The SCANNER provides on-screen instructions on how to
perform the tests.
Injector Tests
Test type 1
There are two different types of injector tests available on Hyundai
vehicles, the type of test is determined by the vehicle system and the
SCANNER automatically presents the correct tests.
One type of test is carried out with the engine RUNNING, it disables a
selected injector for a set time and the engine accordingly should run
rough while it is disabled. This can be used as a cylinder balance check
or to check for a ‘dead’ cylinder or injector.
Test type 2
The other test is carried out with the engine OFF and ignition ON, it
switches the injector from the engine ECM/PCM and can be checked by
taking a voltage reading from the switch side of the injector. The reading
should ‘spike’ as the injector is opened, it can also be checked with the
MODIS Labscope, a Snap-on Vantage or oscilloscope for a conventional
injector pattern showing the injector opening, holding and then closing.
The fuel pump does not operate during this test.

Special Notes on Vehicle Communications
Using MODIS on Hyundai vehicles with the Hyundai-2 adaptor
NOTE FOR MODIS:Side power must be supplied to the Hyundai-2
adaptor on the following Hyundai vehicles:
9/94-95 Excel 1.5L SOHC
11/92-95 S Coupe 1.5L
92-95 S Coupe 1.5L Turbo
Waiting for Data
On some vehicles when CODES & DATA, CODES ONLY or DATA
ONLY is selected the SCANNER can take some time to establish
communication with the vehicle system selected. This is a normal
operation of the SCANNER and the vehicle and is not indicative of a
vehicle or SCANNER problem. This can apply to Engine, Auto trans,
ABS and Airbag systems.
Data Refresh Rates
On some systems on Hyundai vehicles the rate at which live data
information is updated on the screen can appear to be slow.
This is normal for the communication type on these vehicles.
For vehicles that have the TEST MENU selection (NOT vehicles with
the CODES & DATA selection) a faster update rate of the information is
achieved by using the Custom Data List selection on the DATA ONLY
exit menu.
By selecting only a few parameters for viewing the update rate can
be enhanced. For example if only the RPM, IGN ADVANCE, MAF and
INJECTION mS were of interest, these can be selected from the Custom
Data List and then only these parameters will be displayed on the
screen.
Data Appears Frozen
On some Scoupe (11/92 to 95), Sonata (1990 to 1998) and Excel
(9/94 to 2000) models when viewing a live data display with the key
on and the engine off (KOEO) the data will appear to be frozen on the
screen. This a normal function of the vehicle, it will not update live data
information with the engine not running. Codes may be read and erased
with the KOEO, but the vehicle ECU cannot set codes in this mode,
codes will only be set while the engine is running.

Hyundai
Hyundai – General Notes
Code Definitions
When a code is transmitted by a vehicle ECU to the SCANNER, the
code will indicate there may be a problem either in the indicated sensor/
actuator or in the wiring for that sensor/actuator.
Use the codes as a guide when repairing vehicle systems – remember
wiring and connectors are far more likely to cause problems than faulty
sensors and actuators.
Clear Code exceptions
There are various Hyundai systems that do not support electronic clear
codes, this means that the vehicle system itself has no provision for
clear codes from a scan tool. The following is a list of those vehicle
systems:
Excel Automatic Transmission 1990 – August 1994
Excel Engine July 1992 – August 1994
Sonata 2.4L Automatic Transmission 1989 – 1991
To clear codes from these systems, disconnect a battery terminal for 1
minute. When disconnecting battery terminals observe all necessary
precautions.
Setting Codes
If the SCANNER module is communicating with a vehicle and a code
is set the MODIS may or may not beep depending on what type of
communication system the vehicle has.
If you are unsure of whether the SCANNER is displaying codes correctly
create a code by removing the connector from a known sensor and then
check on the screen to see if the code has been set by the vehicle and
sent to the SCANNER. You may need to run the engine at operating
temperature for a while or cycle the ignition off and on to get the code to
set in the vehicle’s computer.

CAUTION FOR ABS AND SRS SYSTEMS
Before attempting any repairs on vehicles fitted with ABS or SRS Airbag
systems observe all precautions the manufacturer specifies for these
systems.
Used Import Vehicles
Used Import vehicles are vehicles that were sold new in Japan and have
since been exported to other countries including Australia and New
Zealand. The SCANNER does not list every model that is available but
does cover the more popular vehicles that are available.
CAUTION: Although every effort has been made, due to the many
models available and the lack of information available for these
vehicles the information that is contained in the SCANNER for these
Used Import vehicles may not always be accurate for the particular
model being tested.
SCANNER Communication Types
The SCANNER supports Subaru live data as well as Auto Code Read
and Manual Code Read. Live Data systems include Engine systems for
selected models, Automatic Transmissions for selected models and ABS
for selected models. See applicable coverage sheets for more coverage
details.
The SCANNER will specify what is available on specific vehicles.

Important notes on Subaru Live Data
1. Subaru Vehicles that use the Multi-2 Adaptor
When testing Subaru vehicles that use the 9-pin Multi-2-C connector, the
adaptor must have side power supplied to it for communication. Use the
battery power lead to supply the Multi-2 adaptor with side power.
2. Refresh Rate
Due to the speed at Subaru Electronic Control Units (ECU’s)
communicate with the SCANNER the data refresh rate may be slow
compared to some other live data systems. This is not controlled by the
SCANNER but by the vehicle ECU.
3. Communication Dropouts
As above the Subaru Electronic Control Units may be delayed
in responding to the SCANNER, this may manifest itself in a very
intermittent loss of communication with the vehicle. This is not controlled
by the SCANNER but by the vehicle ECU.
Communications may also dropout if the vehicle is started while the
SCANNER is communicating.
4. Establishing Communication
Some vehicle systems may take up to 10 seconds for the SCANNER to
establish communication.
If there is no response after 20 seconds or the no communication screen
appears, exit by pressing “N” and press “N” again to clear the vehicle ID
information. Re-enter the vehicle ID and try to communicate again with
the vehicle. If no communication occurs again then refer to Appendix B
in this Reference Manual.

Subaru
Code Type 08 – Subaru
– Engine, Auto Transmission, ABS and SRS Airbag
Subaru uses two types of code patterns: type 8a for engines, 4EAT
(version 2) transmissions, ABS and Airbag and type 8b for 4EAT (version
1) transmissions.
Code type 8a flashes a two-digit (long/short) code. The LED flashes
each 10’s place digit as 1.2-second pulses, with 0.3 second between
each pulse. The LED flashes each 1’s place digit as 0.2-second pulses,
with 0.3 second between each pulse. There is a 0.3-second pause
between each digit, and a 1.8-second pause between multiple codes.
Code type 8b consists of a 2-second flash, followed by a 1-second
pause, followed by a series of short (0.1-second) flashes. FWD vehicles
will have ten short flashes, 4WD will have eleven short flashes. The short
flashes represent code numbers 1 through 10 (or 11). A long (0.6second) flash indicates a fault at the indicated position. For example,
SHORT—SHORT—SHORT—SHORT—LONG—SHORT—SHORT—
SHORT—SHORT—SHORT—SHORT indicates code 5 because the fifth
flash is long. If no codes are present the eleven flashes will all be short
(0.1-second). The code sequence is followed by a 2.5-second pause, a
2-second flash, and then the pattern repeats itself.

Auto Code Read
When using Auto Code Read the SCANNER is connected to the vehicle
and will read and display any engine codes transmitted by the vehicle
on the screen. Any codes present are displayed on the screen with the
code number and description of the code.
NOTE: When a code is transmitted by the vehicle to the SCANNER
the code will indicate there may be a problem either in the WIRING
between the ECU and the indicated sensor/actuator or in the
indicated sensor/actuator.
Subaru uses three types of diagnostic connectors for transmitting
trouble codes. The 13-pin and 17-pin connectors require Multi-1 adaptor
hookup. The 9-pin connector requires the Multi-2C adaptor.
IMPORTANT: Use the Multi-1 adaptor and yellow terminal converters for
the 13-pin and 17-pin connectors. Connect the ground extension from
the Multi-1 black lead to vehicle ground.
All vehicles with 9-pin connector use
Multi-2-C adaptor.
All models
Use ground

Subaru Auto Code Reading
During Subaru auto code reading, you must perform certain diagnostic
checks on the vehicle. Two different checks must be performed: ECS
check (U-check), and D-check. The specific steps you must perform
depend on the Subaru model and year you are testing:
• ECS Check (U-Check) — All Subarus, you do this only if the ECS
lamp on the dash is lit
• Pre-1987 MPI D-Check — All 1983-86 vehicles with multipoint
injection (MPI)
• MPI D-check — 1987-91 multipoint injection (MPI) vehicles.
Failure to follow the required procedure may result in misreading codes
or inaccurate diagnosis. The following sections tell you how to perform
these checks. Use these procedures with the AUTO CODE READ
instructions in the previous section.
ECS Check (U-Check)
On pre-1987 vehicles the ECU does not have memory capability.
CAUTION: On these vehicles, do not turn off the ignition if the ECS lamp
is lit or the trouble codes can be lost.
If the ECS lamp is not lit, proceed to the D-check procedure for the
vehicle you are testing. If the ECS lamp is lit:
1. On vehicles with ECU memory capability, continue with step 2. On
vehicles without ECU memory capability, leave the engine running
and skip to step 3.
2. On vehicles with ECU memory, turn the key off and connect the
vehicle read-memory connectors together. Some cars have black
connectors, some have clear connectors.
3. Identify the vehicle, connect the SCANNER, and confirm the
identification. On vehicles with ECU memory capability, turn the key
on and leave the engine off.
4. Select CODE FUNCTIONS from the MAIN MENU. Then select AUTO
CODE READ and follow the instructions in the previous section,
“Using AUTO CODE READ.”
At this point, the SCANNER will read and display any codes stored in
the ECU memory
5. Disconnect the read-memory connectors previously connected.
6. Proceed to the D-check procedure for the vehicle you are testing.
60
Subaru
Subaru – Engine
Subaru Pre-1987 MPI D-Check
Use this D-check procedure for all 1985-86 vehicles with multipoint
injection (MPI). If the ECS lamp is lit, perform the ECS check (U-check)
before doing this D-check. With the SCANNER connected to the vehicle,
proceed as follows:
1. Connect the green D-check connectors.
2. Turn the ignition on but do not start the engine. The ECS lamp
should light.
3. Start the engine. The ECS lamp should go off.
4. Idle the engine 2 minutes; then snap the throttle fully open 5 times.
5. Briefly race the engine to activate the pressure switch test; then
drive the car above 6 mph. (This can be done carefully on a service
rack, if necessary.) Run the engine at 2500 rpm until the ECS lamp
lights. A flashing lamp means the system is OK. A continuously lit
lamp means trouble codes are present. The SCANNER will read the
codes.
6. Select AUTO CODE READ from the CODE FUNCTIONS menu and
follow the instructions in the section, “Using AUTO CODE READ.”
7. Repeat this procedure until no trouble codes are found.
8. Disconnect the D-check connectors.
1987-91 MPI D-Check
Use this D-check procedure for all 1987-91 multipoint injection (MPI)
vehicles. If the ECS lamp is lit, perform the ECS check (U-check) before
doing this D-check. With the SCANNER connected to the vehicle,
proceed as follows:
1. Start the engine and warm it to normal operating temperature.
2. Turn off the engine and connect the green D-check connectors.
3. Turn the ignition on, but do not start the engine. The ECS lamp
should light.
4. Depress the accelerator completely, release it halfway, hold it for two
seconds, and then release it.
5. Start the engine. The ECS lamp should go off.
61
Subaru
Subaru – Engine
6. Drive the vehicle at least 7 mph for at least one minute. (This can
be done carefully on a service rack, if necessary.) Shift a manual
transmission vehicle into 4th gear.
7. Warm the engine at 2000 rpm until the ECS lamp turns on. A flashing
lamp indicates the system is OK. A continuously lit lamp indicates
trouble codes are present. The SCANNER will read these codes.
8. Select AUTO CODE READ from the CODE FUNCTIONS menu and
follow the instructions in the section, “Using AUTO CODE READ.”
9. Repeat this procedure until no trouble codes are found.
10.After verifying the repair, repeat the D-check procedure with the
read-memory connectors connected to clear codes from ECU
memory.
11.Disconnect the D-check connectors.
Subaru Identity Codes
Some pre 1994 Subaru’s output an identity code which the SCANNER
will read. This code is for vehicle identification and is NOT a trouble
code. The code is displayed when there are no trouble codes present
and is not displayed with trouble codes. No description will be displayed
after this identity code.
If in doubt remove a known sensor to induce a code, run test to confirm.
After testing replace disconnected sensor (and clear codes).

Manual Code Read
During Manual Code Read the SCANNER is not connected to the
vehicle but the SCANNER may display on-screen instructions. When a
vehicle system is Manual Code Read the codes must be activated by
bridging pins together in the diagnostic connector and then read on the
Check Engine Lamp. The SCANNER provides on screen information
on how and where to do this under the CODE FUNCTIONS selection.
Refer to the diagrams below for the correct pins to bridge to initiate code
reading.
The SCANNER provides a list of the code numbers and their
descriptions on screen, located also under the CODE FUNCTIONS

Manual Code Read
During Manual Code Read the SCANNER is not connected to the
vehicle but the SCANNER may display on-screen instructions. To read
the codes on Subaru Automatic Transmissions a procedure must
be followed to activate code output by the vehicle. The instructions
for these procedures are listed on the SCANNER under the CODE
FUNCTIONS selection as well as the list of codes for the particular
vehicle ID entered.
The transmission control systems are placed in the diagnostic, codedisplay, mode by performing vehicle-specific diagnostic routines. These
routines consist of a series of ignition cycles, throttle movements, and
gear selections.
To read Subaru transmission codes manually, you must follow the
appropriate diagnostic procedure. Failure to follow the procedure may
result in misreading codes or inaccurate diagnosis. The Subaru control
systems are placed in the diagnostic, code-display, mode as explained
in the following sections.
NOTE: When a code is transmitted by the vehicle to the SCANNER
the code will indicate there may be a problem either in the WIRING
between the ECU and the indicated sensor/actuator or in the
indicated sensor/actuator.

1987-91 4EAT Transmission (Version 1)
Use this procedure to test the 4EAT transmission in 1987-94 L-series,
and 1988-90 Leone.
You can determine if any codes are present by simply turning the
ignition on (engine off). Codes are present if the POWER lamp flashes
four times, after the 2 second bulb check. If the POWER lamp remains
on, there is a problem in the lamp circuit or with the controller. If the
lamp remains off after the 2 second lamp check, no codes are present.
To place the transmission controller in the diagnostic, code-display
mode, proceed as follows:

together in the diagnostic connector and then read on the ABS or SRS
Lamp. The SCANNER provides on screen information on how and
where to do this under the CODE FUNCTIONS selection. Refer to the
diagrams below for the correct pins to bridge to initiate code reading.
The SCANNER provides a list of the code numbers and their
descriptions on screen, located also under the CODE FUNCTIONS
selection.
NOTE: When a code is transmitted by the vehicle to the SCANNER
the code will indicate there may be a problem either in the WIRING
between the ECU and the indicated sensor/actuator or in the
indicated sensor/actuator.

If a control system fails to communicate with the SCANNER, a problem
may exist with the wiring or other circuit parts on the car; or the vehicle
identification to the SCANNER may be incorrect. The vehicle’s failure to
communicate can be an important symptom for diagnosing a driveability
problem.
NOTE: Also check vehicle specific
information in Part 2.

Appendix B — Vehicle Does Not Communicate
General Checks
Check the following points first:
1. Vehicle identification — Check the vehicle identification entered.
The control modules do not all transmit the same amount of data
at the same speed. Nor do they all transmit the same information
in the same order. Additionally, the SCANNER must address,
or “question,” some modules to establish communication. All of
these points mean that the SCANNER must know exactly what year
and model module it is connected to. If the SCANNER thinks it is
receiving data from one car and it is connected to another (through
incorrect identificaton), it will either not communicate at all or display
some data readings that are clearly incorrect. Always enter a new
vehicle identification when testing a new vehicle, even if two vehicles
are exactly the same model with the same engine.
2. SCANNER connections — See "Check SCANNER Connection and
Operation" for information on SCANNER cables and connections.
3. Loss of power to a control module — The modules receive battery
voltage through one or more fuses or fusible links in the wiring
harness. Use a wiring diagram to check module connections for
battery voltage and ground. If a module fuse or fusible link is open,
the module cannot communicate with the SCANNER.
3. Ignition off when connecting SCANNER — Be sure the ignition is
off when connecting and disconnecting the SCANNER. If the ignition
is on when the SCANNER is connected or disconnected, SCANNER
memory may be disrupted. Erase and reenter vehicle identification if
this occurs.
No Codes are Displayed
Most data stream vehicles transmit trouble codes along with their data.
Therefore, if the data is displayed, an absence of trouble codes does
not indicate a communication problem. Some vehicles transmit trouble
codes separately from the data stream.
Some vehicles with AUTO CODE READ capability transmit a "pass
code," others do not. Therefore, the absence of trouble codes may or
may not indicate that there is a communication problem. However, if the
car you are testing will not start, or has a driveability symptom, and no
codes are present, there probably is a communication problem.
83
Appendix B — Vehicle Does Not Communicate
You can diagnose a communication problem on some AUTO CODE
READ cars by attempting to manually gather codes. Refer to "Reading
Different Code Types" in Scanner Plug-in User’s Manual for vehiclespecific manual code gathering instructions. However, many AUTO
CODE READ cars do not provide manual code gathering as an option.
You can also try inducing a trouble code. Unfortunately, there is no
common way to do this. The method will vary, depending on the
vehicle make and model year. Generally, you can induce a code
by disconnecting a resistive-type sensor, such as a TPS or coolant
temperature sensor. However, the best method is to use your experience
based on what you have seen on similar cars in the past.
Kia Vehicles with Auto Code Read
The Kia electronic control assembly for engine and auto trans
continuously monitors engine and transmission operation for conditions
that would set codes. If no codes are present, the system will not
transmit any for the SCANNER to display. When you press Y in this
case to select either key-on, engine-off or engine-running self-test, the
SCANNER will display:
SELF TEST INITIATED ... WAITING FOR CODES.
Because no codes are present for the system to transmit, the display will
not change. If the system does not respond within a few seconds, press
N to return to the SERVICE CODE MENU.
IF NO CODES DISPLAYED AND YOU WISH TO VERIFY THAT
THE VEHICLE IS OK PULL A KNOWN SENSOR, RUN TEST AND
KNOWN CODE SHOULD APPEAR – REPLACE SENSOR AND
CLEAR CODES.
Engine Will Not Start and ECU Will Not Communicate
With Ignition On
If the engine does not start and the PCM will not communicate with the
ignition on, follow the instructions in the section titled "Check the CHECK
ENGINE Lamp" to see if the vehicle will display codes on the instrument
panel lamp. Also make these basic tests:
• Battery — Check the battery state of charge and cranking capacity.
Note: The SCANNER may appear to operate normally even if the
battery does not have enough power to crank the engine or operate
the vehicle computer.
84
Appendix B — Vehicle Does Not Communicate
• ECU supply voltage — Check a wiring diagram for the location of
the ECU fuses or fusible links and test for an open circuit.
• ECU ground — Use a wiring diagram to identify the location of the
ground connection. An open ground can keep a fuel-injected engine
from starting. A high-resistance, or “dirty,” ground can cause overall
poor operation.
An open ground or battery voltage (B+) circuit on a fuel-injected engine
will remove power from the PCM and keep the engine from starting.
A carbureted engine may start and run even if the power circuit to the
PCM is open. It probably will run very poorly, however, because it will be
running without feedback fuel control or spark advance control.
Engine Runs But Will Not Communicate
The way in which the engine runs can be a clue to the cause of a test
problem. If the engine seems to run normally but the PCM will not
communicate with the SCANNER, the cause may be a wiring problem
to the diagnostic connector that does not affect the rest of the system.
If the engine runs poorly, the cause may be a poor system ground or a
voltage problem that affects the PCM or the entire system.
Refer to the sections, "Check the CHECK ENGINE Lamp" and “Check
the diagnostic Connector” for troubleshooting instructions.
Check SCANNER Connection And Operation
Begin troubleshooting the test or communication problem by
determining if the SCANNER is working normally. If the SCANNER
works properly on other vehicles, particularly same-model vehicles, the
problem is probably in the vehicle, not the SCANNER. If the SCANNER
fails to light up or if the readings are unsteady, the SCANNER may be at
fault or there may be a power problem on the vehicle.
If the SCANNER intermittently resets or goes blank, a wire may be
opening intermittently in one of the cables or in the adaptor. Use an
ohmmeter to check continuity of the SCANNER data cable from pin to
pin between the D-shaped connectors at either end of the cable.
85
Appendix B — Vehicle Does Not Communicate
Check the CHECK ENGINE Lamp
Many cars and trucks with PCM diagnostic capabilities have a CHECK
ENGINE lamp on the instrument panel. On some vehicles, the lamp
is labeled simply ENGINE, or has a symbol to indicate the PCM.
Regardless of the label, they all can be referred to as the CHECK
ENGINE lamp.
The CHECK ENGINE lamp can be an important device for checking the PCM’s
ability to transmit to the SCANNER. If the SCANNER cannot communicate
with the vehicle, disconnect the SCANNER and see if the PCM will flash
trouble codes on the CHECK ENGINE lamp. This applies only to some
vehicles.
Turn the ignition on and verify that the CHECK ENGINE lamp lights with
the ignition on and the engine off. If it does not, troubleshoot and repair
the problem before going farther. It could be as simple as a burned out
lamp bulb or a blown fuse. Refer to the carmaker's shop manual for the
CHECK ENGINE lamp troubleshooting procedure on the specific vehicle
you are testing. Common causes of CHECK ENGINE lamp circuit
problems include:
• A blown circuit fuse (GAUGES or other lamp fuse)
• A burned-out lamp bulb
• A wiring or connector problem
• A defective lamp driver
• A diagnostic connector problem
Special Cases — Specific Vehicles
The vehicles listed in the following sections are specific models that may
have problems communicating with the SCANNER.
1989 and later Hyundai Sonatas
Models with 2.4-litre 4-cylinder, or 3.0-litre V6 sohc engines transmit data
at 63 baud. These vehicles can appear to have communication problems
when actually, they simply tranmsit data at a very slow speed. This also
applies to Scoupe late 1992 to 1995 and Excel 1994 to 2000.
The baud rate determines how fast the SCANNER responds to the PCM
and how fast the data readings change on the screen. It also affects
the time that it takes to record a movie. Readings from these vehicles
can take up to seven seconds to change. This display speed, or “data
update rate” depends on the ECU; it is not controlled by the SCANNER.
86
Appendix B — Vehicle Does Not Communicate
Using MODIS on Hyundai Excel and S Coupe vehicles
that use the Hyundai-2 adaptor
The following Hyundai vehicles require side power supplied to the side
of the Hyundai-2 adaptor for communication to establish with the engine
system. Use battery power or cigarette power lead to supply side power
to adaptor.

1.5L SOHC
1992-1195 S Coupe1.5L
1992-1995 S Coupe1.5L-T
Subaru vehicles using the Multi-2 adaptor
Note: Subaru vehicles that use the Multi-2 adaptor must have side
power supplied to side socket of adaptor to establish comunication. Use
battery power or cigarette power lead to supply side power to adaptor.
NOTE: Also check vehicle specific
information in Part 2.
