VEHICLES COVERED
VEHICLES COVERED
All 1996 and newer vehicles (cars and light trucks) sold in the United
States are OBD2 compliant. Coverage for new model vehicles may be
limited and will be available once released by the automaker. Availability
is typically 12 to 24 months after the release of the model year.
Federal law requires that all 1996 and newer cars and light
trucks sold in the United States must be OBD2 compliant; this
includes all Domestic, Asian and European vehicles.
Some 1994 and 1995 vehicles are OBD2 compliant. To find out if a
1994 or 1995 vehicle is OBD2 compliant, check the following:
1. The Vehicle Emissions Control Information (VECI) Label. This
label is located under the hood or by the radiator of most vehicles. If
the vehicle is OBD2 compliant, the label will state “OBD II
Certified.”

Onboard Diagnostics
OBD2 TERMINOLOGY
OBD2 TERMINOLOGY
The following terms and their definitions are related to OBD2 systems.
Read and reference this list as needed to aid in the understanding of
OBD2 systems.

Powertrain Control Module (PCM) - The PCM is the OBD2
accepted term for the vehicle’s “on-board computer.” In addition to
controlling the engine management and emissions systems, the
PCM also participates in controlling the powertrain (transmission)
operation. Most PCMs also have the ability to communicate with
other computers on the vehicle (ABS, ride control, body, etc.).

Monitor - Monitors are “diagnostic routines” programmed into the
PCM. The PCM utilizes these programs to run diagnostic tests, and
to monitor operation of the vehicle’s emissions-related components
or systems to ensure they are operating correctly and within the
vehicle’s manufacturer specifications. Currently, up to fifteen
Monitors are used in OBD2 systems. Additional Monitors will be
added as the OBD2 system is further developed.
Not all vehicles support all fifteen Monitors.
8

Enabling Criteria - Each Monitor is designed to test and monitor the
operation of a specific part of the vehicle’s emissions system (EGR
system, oxygen sensor, catalytic converter, etc.). A specific set of
“conditions” or “driving procedures” must be met before the computer
can command a Monitor to run tests on its related system. These
“conditions” are known as “Enabling Criteria.” The requirements and
procedures vary for each Monitor. Some Monitors only require the
ignition key to be turned “On” for them to run and complete their
diagnostic testing. Others may require a set of complex procedures,
such as, starting the vehicle when cold, bringing it to operating
temperature, and driving the vehicle under specific conditions before
the Monitor can run and complete its diagnostic testing.

Monitor Has/Has Not Run - The terms “Monitor has run” or
“Monitor has not run” are used throughout this manual. “Monitor
has run,” means the PCM has commanded a particular Monitor to
perform the required diagnostic testing on a system to ensure the
system is operating correctly (within factory specifications). The term
“Monitor has not run” means the PCM has not yet commanded a
particular Monitor to perform diagnostic testing on its associated part
of the emissions system.

Trip - A Trip for a particular Monitor requires that the vehicle is
being driven in such a way that all the required “Enabling Criteria”
for the Monitor to run and complete its diagnostic testing are met.
The “Trip Drive Cycle” for a particular Monitor begins when the
ignition key is turned “On.” It is successfully completed when all the
“Enabling Criteria” for the Monitor to run and complete its diagnostic
testing are met by the time the ignition key is turned “Off.” Since
each of the fifteen monitors is designed to run diagnostics and
testing on a different part of the engine or emissions system, the
“Trip Drive Cycle” needed for each individual Monitor to run and
complete varies.
ZR11
Onboard Diagnostics
DIAGNOSTIC TROUBLE CODES (DTCs)

OBD2 Drive Cycle - An OBD2 Drive Cycle is an extended set of
driving procedures that takes into consideration the various types of
driving conditions encountered in real life. These conditions may
include starting the vehicle when it is cold, driving the vehicle at a
steady speed (cruising), accelerating, etc. An OBD2 Drive Cycle
begins when the ignition key is turned “On” (when cold) and ends
when the vehicle has been driven in such a way as to have all the
“Enabling Criteria” met for all its applicable Monitors. Only those
trips that provide the Enabling Criteria for all Monitors applicable to
the vehicle to run and complete their individual diagnostic tests
qualify as an OBD2 Drive Cycle. OBD2 Drive Cycle requirements
vary from one model of vehicle to another. Vehicle manufacturers
set these procedures. Consult your vehicle’s service manual for
OBD2 Drive Cycle procedures.
Do not confuse a “Trip” Drive Cycle with an OBD2 Drive Cycle. A
“Trip” Drive Cycle provides the “Enabling Criteria” for one specific
Monitor to run and complete its diagnostic testing. An OBD2 Drive
Cycle must meet the “Enabling Criteria” for all Monitors on a
particular vehicle to run and complete their diagnostic testing.

Warm-up Cycle - Vehicle operation after an engine off period where
engine temperature rises at least 40°F (22°C) from its temperature
before starting, and reaches at least 160°F (70°C). The PCM uses
warm-up cycles as a counter to automatically erase a specific code
and related data from its memory. When no faults related to the
original problem are detected within a specified number of warm-up
cycles, the code is erased automatically.
DIAGNOSTIC TROUBLE CODES (DTCs)
Diagnostic Trouble Codes (DTCs) are

service procedure in the vehicle’s
Codes (DTCs) are

consulting the vehicle’s service manual
for proper testing procedures for that
particular system, circuit or component.
DTCs are alphanumeric codes that are used to identify a
problem that is present in any of the systems that are
monitored by the on-board computer (PCM). Each trouble
code has an assigned message that identifies the circuit,
component or system area where the problem was found.
OBD2 diagnostic trouble codes are made up of five characters:

The 1st character is a letter (B, C, P or U). It identifies the
“main system” where the fault occurred (Body, Chassis, Powertrain,
or Network).

The 2nd character is a numeric digit (0 thru 3). It identifies the
“type” of code (Generic or Manufacturer-Specific).
Generic DTCs are codes that are used by all vehicle manufacturers. The standards for generic DTCs, as well as their
definitions, are set by the Society of Automotive Engineers (SAE).
9
Onboard Diagnostics
DIAGNOSTIC TROUBLE CODES (DTCs)
Manufacturer-Specific DTCs are codes that are controlled by
the vehicle manufacturers. The Federal Government does not
require vehicle manufacturers to go beyond the standardized
generic DTCs in order to comply with the new OBD2 emissions
standards. However, manufacturers are free to expand beyond
the standardized codes to make their systems easier to
diagnose.

The 3rd character is a letter or a numeric digit (0 thru 9, A thru F).
It identifies the specific system or sub-system where the problem is
located.

The 4th and 5th characters are letters or numeric digits (0 thru 9, A
thru F). They identify the section of the system that is malfunctioning.

ZR11
Onboard Diagnostics
DIAGNOSTIC TROUBLE CODES (DTCs)
DTCs and MIL Status
When the vehicle’s on-board computer detects
a failure in an emissions-related component or
system, the computer’s internal diagnostic
program assigns a diagnostic trouble code
(DTC) that points to the system (and subsystem)
where the fault was found. The diagnostic
program saves the code in the computer’s
memory. It records a “Freeze Frame” of
conditions present when the fault was found, and lights the Malfunction
Indicator Lamp (MIL). Some faults require detection for two trips in a row
before the MIL is turned on.
The “Malfunction Indicator Lamp” (MIL) is the accepted term
used to describe the lamp on the dashboard that lights to warn
the driver that an emissions-related fault has been found.
Some manufacturers may still call this lamp a “Check Engine”
or “Service Engine Soon” light.
There are two types of DTCs used for emissions-related faults: Type “A”
and Type “B.” Type “A” codes are “One-Trip” codes; Type “B” DTCs are
usually Two-Trip DTCs.
When a Type “A” DTC is found on the First Trip, the following events
take place:

The computer commands the MIL “On” when the failure is first found.

If the failure causes a severe misfire that may cause damage to the
catalytic converter, the MIL “flashes” once per second. The MIL
continues to flash as long as the condition exists. If the condition
that caused the MIL to flash is no longer present, the MIL will light
“steady” On.

A DTC is saved in the computer’s memory for later retrieval.

A “Freeze Frame” of the conditions present in the engine or emissions
system when the MIL was ordered “On” is saved in the computer’s
memory for later retrieval. This information shows fuel system status
(closed loop or open loop), engine load, coolant temperature, fuel trim
value, MAP vacuum, engine RPM and DTC priority.
When a Type “B” DTC is found on the First Trip, the following events
take place:

The computer sets a Pending DTC, but the MIL is not ordered “On.”
“Freeze Frame” data may or may not be saved at this time
depending on manufacturer. The Pending DTC is saved in the
computer’s memory for later retrieval.

If the failure is found on the second consecutive trip, the MIL is
ordered “On.” “Freeze Frame” data is saved in the computer’s
memory.

If the failure is not found on the second Trip, the Pending DTC is
erased from the computer’s memory.
The MIL will stay lit for both Type “A” and Type “B” codes until one of
the following conditions occurs:
11
Onboard Diagnostics
OBD2 MONITORS

If the conditions that caused the MIL to light are no longer present
for the next three trips in a row, the computer automatically turns the
MIL “Off” if no other emissions-related faults are present. However,
the DTCs remain in the computer’s memory as a history code for 40
warm-up cycles (80 warm-up cycles for fuel and misfire faults). The
DTCs are automatically erased if the fault that caused them to be
set is not detected again during that period.

Misfire and fuel system faults require three trips with “similar
conditions” before the MIL is turned “Off.” These are trips where the
engine load, RPM and temperature are similar to the conditions
present when the fault was first found.
After the MIL has been turned off, DTCs and Freeze Frame
data stay in the computer’s memory.

Erasing the DTCs from the computer’s memory can also turn off the
MIL. See ERASING DIAGNOSTIC TROUBLE CODES (DTCs) on
page 46, before erasing codes from the computer’s memory. If a
Diagnostic Tool or Scan Tool is used to erase the codes, Freeze
Frame data will also be erased.
OBD2 MONITORS
Currently, fifteen Monitors are supported by OBD2 systems. Additional
monitors may be added as a result of Government regulations as the
OBD2 system grows and matures. Not all vehicles support all fifteen
Monitors. Additionally, some Monitors are supported by “spark ignition”
vehicles only, while others are supported by “compression ignition”
vehicles only.
Monitor operation is either “Continuous” or “Non-Continuous,”
depending on the specific monitor.
Continuous Monitors
Three of these Monitors are designed to constantly monitor their
associated components and/or systems for proper operation.
Continuous Monitors run constantly when the engine is running. The
Continuous Monitors are:
Comprehensive Component Monitor (CCM)
Misfire Monitor
Fuel System Monitor
Non-Continuous Monitors
The other twelve Monitors are “non-continuous” Monitors. “Noncontinuous” Monitors perform and complete their testing once per trip.
The “non-continuous” Monitors are:

Preparation for Testing
BEFORE YOU BEGIN
BEFORE YOU BEGIN
Mechanical problems such as low
oil level or damaged hoses, wiring
or electrical connectors can cause
poor engine performance and
may also cause a fault code to set.
Fix any known mechanical
problems before performing any
test. See your vehicle’s service manual or a mechanic for more information.
Check the following areas before starting any test:

Check the engine oil, power steering fluid, transmission fluid (if
applicable), engine coolant and other fluids for proper levels. Top off
low fluid levels if needed.

Make sure the air filter is clean and in good condition. Make sure all
air filter ducts are properly connected. Check the air filter ducts for
holes, rips or cracks.

Make sure all engine belts are in good condition. Check for cracked,
torn, brittle, loose or missing belts.

Make sure mechanical linkages to engine sensors (throttle, gearshift
position, transmission, etc.) are secure and properly connected. See

CODE RETRIEVAL PROCEDURE
CODE RETRIEVAL PROCEDURE
Retrieving and using Diagnostic Trouble Codes (DTCs) for
troubleshooting vehicle operation is only one part of an
overall diagnostic strategy.
Never replace a part based only on the DTC definition.
Each DTC has a set of testing procedures, instructions and
flow charts that must be followed to confirm the location of
the problem. This information is found in the vehicle's
service manual. Always refer to the vehicle's service manual
for detailed testing instructions.
Check your vehicle thoroughly before performing
any test. See BEFORE YOU BEGIN on page 15 for
details.
ALWAYS observe safety precautions whenever working on a
vehicle. See IMPORTANT SAFETY INFORMATION on page 1
for more information.
1. Turn the ignition off.
2. Locate the vehicle's 16-pin Data Link
Connector (DLC). See page 2 for
connector location.
Some DLCs have a plastic cover
that must be removed before
connecting the Code Reader
cable connector.
If the Code Reader is ON, turn it
OFF by pressing the POWER/LINK
button BEFORE connecting
the Code Reader to the DLC.
3. Connect the Code Reader cable connector to the vehicle’s DLC.
The cable connector is keyed and will only fit one way.

If you have problems connecting the cable connector to the DLC,
rotate the connector 180° and try again.

If you still have problems, check the DLC on the vehicle and on
the Code Reader. Refer to your vehicle’s service manual to
properly check the vehicle’s DLC.
4. Turn the ignition on. DO NOT start the engine.
5. When the Code Reader’s cable connector is properly connected to
the vehicle’s DLC, the unit automatically turns ON.

16
If the unit does not power on automatically when connected to
the vehicle’s DLC connector, it usually indicates there is no
power present at the vehicle’s DLC connector. Check your fuse
panel and replace any burned-out fuses.

Using the Code Reader
CODE RETRIEVAL PROCEDURE

Yellow LED – Indicates one of the following conditions:
A. A PENDING CODE IS PRESENT –
If the yellow LED is illuminated, it
may indicate a Pending code is
present. Check the Code Reader’s
display for confirmation. A Pending
code is confirmed by the presence
of a numeric code and the word
PENDING on the Code Reader’s
display.
B. MONITOR NOT RUN STATUS – If
the Code Reader’s display shows a
zero (indicating there are no DTC’s
present in the vehicle’s computer
memory), but the yellow LED is
illuminated, it may be an indication
that some of the Monitors
supported by the vehicle have not
yet run and completed their
diagnostic testing. Check the Code
Reader’s display for confirmation.
All Monitor icons that are blinking
have not yet run and completed
their diagnostic testing; all Monitor
icons that are solid have run and
completed their diagnostic testing.

Red LED – Indicates there is a
problem with one or more of the
vehicle’s systems. The red LED is
also used to indicate that DTC(s)
are present (displayed on the Code
Reader’s screen). In this case, the
Malfunction Indicator (Check Engine)
lamp on the vehicle’s instrument
panel will be illuminated.

DTC’s that start with “P0”, “P2” and some “P3” are considered
Generic (Universal). All Generic DTC definitions are the same on all
OBD2 equipped vehicles. The Code Reader automatically displays
the code definitions (if available) for Generic DTC’s.

DTC’s that start with “P1” and some “P3” are Manufacturer specific
codes and their code definitions vary with each vehicle manufacturer.
13. If more than one DTC was retrieved,
and to view Freeze Frame Data, press
and release the DTC/FF button, as
necessary.

Using the Code Reader
THE SYSTEM MENU

Freeze Frame Data (if available) will display after DTC #1.
If more than one malfunction is present that causes more than
one DTC to be set, only the code with the highest priority will
contain Freeze Frame data. The code designated “01” on the
Code Reader display is referred to as the PRIORITY code,
and Freeze Frame data always refers to this code. The priority
code is also the one that has commanded the MIL on.
14. When the last retrieved DTC has been displayed and the DTC/FF
button is pressed, the Code Reader returns to the “Priority” Code.
15. Determine engine system(s) condition by viewing the Code
Reader’s display for any retrieved Diagnostic Trouble Codes, code
definitions and Freeze Frame data, interpreting the green, yellow
and red LEDs.

If DTC’s were retrieved and you are going to perform the repairs
yourself, proceed by consulting the Vehicle’s Service Repair
Manual for testing instructions, testing procedures, and flow
charts related to retrieved code(s).

To prolong battery life, the Code Reader automatically shuts
“Off” approximately three minutes after it is disconnected from
the vehicle. The DTCs retrieved, Monitor Status and Freeze
Frame data (if any) will remain in the Code Reader’s memory,
and may be viewed at any time by turning the unit “On”. If the
Code Reader’s batteries are removed, or if the Code Reader is
re-linked to a vehicle to retrieve codes/data, any prior
codes/data in its memory are automatically cleared.

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the Code Reader’s ERASE function is used to erase
DTCs from the vehicle's on-board computer, "Freeze Frame"
data and manufacturer-specific-enhanced data are also
erased. Unlike other codes which can be removed from the
vehicle's control module, PERMANENT codes cannot. This
holds true regardless of the tool being used or color of the
status LED display. PERMANENT codes will automatically
erase when the control module no longer detects the fault
that originally caused the code.
If you plan to take the vehicle to a Service Center for repair, DO NOT
erase the codes from the vehicle's computer. If the codes are erased,
valuable information that might help the technician troubleshoot the
problem will also be erased.
Erase DTCs from the computer's memory as follows:
When DTCs are erased from the vehicle's computer memory, the
I/M Readiness Monitor Status program resets the status of all
Monitors to a not run "flashing" condition. To set all of the Monitors
to a DONE status, an OBD2 Drive Cycle must be performed.
Refer to your vehicle's service manual for information on how to
perform an OBD2 Drive Cycle for the vehicle under test.

I/M READINESS TESTING

If the erase was not successful, an
advisory message shows on the
display indicating the erase request
was sent to the vehicle’s computer.
Press the SYSTEM MENU
button to return to the System Menu.
Erasing DTCs does not fix the problem(s) that caused the
code(s) to be set. If proper repairs to correct the problem that
caused the code(s) to be set are not made, the code(s) will
appear again (and the Check Engine Light will illuminate) as
soon as the vehicle is driven long enough for its Monitors to
complete their testing.
I/M READINESS TESTING
I/M is an Inspection and Maintenance program legislated by the
Government to meet federal clean-air standards.
The program requires that a vehicle be taken periodically to an
Emissions Station for an "Emissions Test" or "Smog Check,” where the
emissions-related components and systems are inspected and tested
for proper operation. Emissions Tests are generally performed once a
year, or once every two years.
On OBD2 systems, the I/M program is enhanced by requiring vehicles
to meet stricter test standards. One of the tests instituted by the Federal
Government is called I/M 240. On I/M 240, the vehicle under test is
driven under different speeds and load conditions on a dynamometer for
240 seconds, while the vehicle's emissions are measured.
Emissions tests vary depending on the geographic or regional
area in which the vehicle is registered. If the vehicle is
registered in a highly urbanized area, the I/M 240 is probably
the type of test required. If the vehicle is registered in a rural
area, the stricter “dynamometer type” test may not be required.
I/M Readiness Monitors
I/M Readiness shows whether the various emissions-related systems on
the vehicle are operating properly and are ready for Inspection and
Maintenance testing.
Emissions Inspection and Maintenance (I/M) Readiness
Monitor Status Information
I/M Readiness Monitor Status shows which of the vehicle's Monitors
have run and completed their diagnosis and testing, and which ones
have not yet run and completed testing and diagnosis of their
designated sections of the vehicle's emissions system.

48
If a Monitor was able to meet all the conditions required to enable it
to perform the self-diagnosis and testing of its assigned engine
system, it means the monitor "HAS RUN.”
ZR11
Using the Code Reader
I/M READINESS TESTING

If a Monitor has not yet met all the conditions required for it to
perform the self-diagnosis and testing of its assigned engine system;
it means the Monitor "HAS NOT RUN.”
The Monitor Run/Not Run status does not show whether
or not a problem exists in a system. Monitor status only
indicates whether a particular Monitor has or has not run
and performed the self-diagnosis and testing of its
associated system.
Performing I/M Readiness Quick Check
When a vehicle first comes from the factory, all Monitors
indicate a “HAVE RUN” status. This indicates that all Monitors
have run and completed their diagnostic testing. The “HAVE
RUN” status remains in the computer's memory, unless the
Diagnostic Trouble Codes are erased or the vehicle's
computer memory is cleared.
The Code Reader allows you to retrieve Monitor/System Status
Information to help you determine if the vehicle is ready for an
Emissions Test (Smog Check). In addition to retrieving Diagnostic
Trouble Codes, the Code Reader also retrieves Monitor Run/Not Run
status. This information is very important since different areas of the
state/country have different emissions laws and regulations concerning
Monitor Run/Not Run status.
Before an Emissions Test (Smog Check) can be performed, your
vehicle must meet certain rules, requirements and procedures legislated
by the Federal and state (country) governments where you live.
1. In most areas, one of the requirements that must be met before a
vehicle is allowed to be Emissions Tested (Smog Checked) is that
the vehicle does not have any Diagnostic Trouble Codes present
(with the exception of PENDING Diagnostic Trouble Codes).
2. In addition to the requirement that no Diagnostic Trouble Codes be
present, some areas also require that all the Monitors that a
particular vehicle supports indicate a "Has Run" status condition
before an Emissions Check may be performed.
3. Other areas may only require that some (but not all) Monitors
indicate a "Has Run" status before an Emissions Test (Smog Check)
may be performed.
Monitors with a "Has Run" status indicate that all the
required conditions they needed to perform diagnosis and
testing of their assigned engine area (system) have been
met, and all diagnostic testing has completed successfully.
Monitors with a "Has Not Run" status have not yet met the
conditions they need to perform diagnosis and testing of
their assigned engine area (system), and have not been
able to perform diagnostic testing on that system.
The green, yellow and red LEDs provide a quick way to help you
determine if a vehicle is ready for an Emissions Test (Smog Check).
Follow the instructions below to perform the Quick Check.
49
Using the Code Reader
I/M READINESS TESTING
Perform the CODE RETRIEVAL PROCEDURE as described on page
16, then interpret the LED indications as follows:
Interpreting I/M Readiness Test Results
1. GREEN LED - Indicates that all engine
systems are "OK" and operating
normally (all Monitors supported by the
vehicle have run and performed their
self-diagnostic testing). The vehicle is
ready for an Emissions Test (Smog
Check), and there is a good possibility
that it can be certified.
2. YELLOW LED - Determine from the
CODE RETRIEVAL PROCEDURE
(page 16) which of the two possible
conditions is causing the yellow LED to
light.

If a "PENDING" Diagnostic Trouble
Code is causing the yellow LED to
light, it is possible that the vehicle will
be allowed to be tested for emissions
and certified. Currently, most areas
(states / countries) will allow an
Emissions Test (Smog Check) to be
performed if the only code in the
vehicle's computer is a "PENDING"
Diagnostic Trouble Code.

If the illumination of the Yellow LED
is being caused by monitors that
“have not run” their diagnostic
testing, then the issue of the vehicle
being ready for an Emissions Test
(Smog Check) depends on the
emissions regulations and laws of
your local area.
- From the code retrieval procedure, determine the status of
each Monitor (a solid Monitor icon shows Monitor "Has Run"
status, a flashing Monitor icon indicates "Has Not Run" status).
Take this information to an emissions professional to
determine (based on your test results) if your vehicle is ready
for an Emissions Test (Smog Check).
3. RED LED - Indicates there is a problem
with one or more of the vehicle's
systems. A vehicle displaying a red LED
is definitely not ready for an Emissions
Test (Smog Check). The red LED is
also an indication that there are
Diagnostic Trouble Code(s) present
(displayed on the Code Reader's
screen). The Malfunction Indicator
(Check Engine) Lamp on the vehicle's
50
ZR11
Using the Code Reader
I/M READINESS TESTING
instrument panel will light steady. The problem that is causing the
red LED to light must be repaired before an Emissions Test (Smog
Check) can be performed. It is also suggested that the vehicle be
inspected/repaired before driving the vehicle further.
If the Red LED was obtained, there is a definite problem present in
the system(s). In these cases, you have the following options.

Repair the vehicle yourself. If you are going to perform the
repairs yourself, proceed by reading the vehicle service manual
and following all its procedures and recommendations.
Take the vehicle to a professional to have it serviced. The
problem(s) causing the red LED to light must be repaired before
the vehicle is ready for an Emissions Test (Smog Check).
Using the I/M Readiness Monitor Status to Confirm a Repair
The I/M Readiness Monitor Status function can be used (after repair of a
fault has been performed) to confirm that the repair has been performed
correctly, and/or to check for Monitor Run Status. Use the following
procedure to determine I/M Readiness Monitor Status:
1. Using retrieved Diagnostic Trouble Codes (DTCs) and code
definitions as a guide, and following manufacturer's repair
procedures, repair the fault or faults as instructed.
2. After the fault or faults have been repaired, connect the Code
Reader to the vehicle's DLC and erase the code or codes from the
vehicle's computer memory.

See page 46 for procedures for ERASING DIAGNOSTIC
TROUBLE CODES (DTCs) from the vehicle's on-board
computer.

Write the codes down on a piece of paper for reference before
erasing.
3. After the erase procedure is performed, most of the Monitor icons on
the Code Reader’s display will be flashing. Leave the Code Reader
connected to the vehicle, and perform a Trip Drive Cycle for each
"flashing" Monitor:
Misfire, Fuel and Comprehensive Component Monitors run
continuously and their icons will always be on solid, even after
the erase function is performed.

Each DTC is associated with a specific Monitor. Consult the
vehicle's service manual to identify the Monitor (or Monitors)
associated with the faults that were repaired. Follow the
manufacturer's procedures to perform a Trip Drive Cycle for the
appropriate Monitors.

While observing the Monitor icons on the Code Reader’s display,
perform a Trip Drive Cycle for the appropriate Monitor or
Monitors.
51
Using the Code Reader
I/M READINESS TESTING
4. When a Monitor's Trip Drive Cycle is performed properly, the
Monitor icon on the Code Reader’s display changes from "flashing"
to "solid,” indicating that the Monitor has run and finished its
diagnostic testing.
52

If, after the Monitor has run, the MIL on the vehicle's dash is not
lit, and no stored or pending codes associated with that
particular Monitor are present in the vehicle's computer, the
repair was successful.

If, after the Monitor has run, the MIL on the vehicle's dash lights
and/or a DTC associated with that Monitor is present in the
vehicle's computer, the repair was unsuccessful. Refer to the
vehicle's service manual and recheck repair procedures.

Live Data Mode
VIEWING LIVE DATA
The Code Reader is a special tool that communicates with the vehicle's
computer. The Code Reader lets you view and/or "capture" (record)
"real-time" Live Data. This information includes values (volts, rpm,
temperature, speed etc.) and system status information (open loop,
closed loop, fuel system status, etc.) generated by the various vehicle
sensors, switches and actuators.
In effect the Code Reader lets you view, in "real time", the same signal
values generated by the sensors, actuators, switches and/or vehicle
system status information used by the vehicle's computer when
calculating and conducting system adjustments and corrections.
The real time (Live Data) vehicle operating information (values/status)
that the computer supplies to the Code Reader for each sensor,
actuator, switch, etc. is called Parameter Identification (PID) Data.
Each PID (sensor, actuator switch, status, etc.) has a set of operating
characteristics and features (parameters) that serve to identify it. The
Code Reader displays this information for each sensor, actuator, switch
or status that is supported by the vehicle under test.
WARNING: If the vehicle must be driven in order to perform a
troubleshooting procedure, ALWAYS have a second person
help you. One person should drive the vehicle while the other
person observes the Code Reader data. Trying to drive and
operate the Code Reader at the same time is dangerous, and
could cause a serious traffic accident.

O2 Sensor Test
The O2 Sensor Test function lets you retrieve and view O2 sensor
monitor test results for the most recently completed tests from your
vehicle's on-board computer.
Vehicles are equipped with multiple O2 sensors. O2 sensors are installed
both upstream of (before) and downstream of (after) the exhaust system
Catalytic Converters. The name of an O2 sensor identifies its location in the
exhaust system. The name of each O2 sensor is made up of three parts:
O2S XX YY -or- O2S X Y
O2S - this is the basic designation for all O2 sensors.
X or XX - These characters identify the location of the O2 sensor in
relation to a cylinder bank. An O2 sensor for cylinder bank 1 is
identified by the designation “1” or "B1"; a sensor for cylinder bank 2
is identified as “2” or "B2."
”Bank One” indicates the side of the engine where cylinder
number one is located (V-type engines). Bank Two is opposite
of Bank One.
Y or YY - These characters identify the location of the O2 sensor in
relation to the exhaust system catalyst. An O2 sensor located upstream
of the catalyst is identified by the designation “1” or “S1”, a sensor located downstream of the Catalytic Converter is identified as “2” or "S2."
For example, O2S12 or O2SB1S2 is the designation for the
downstream O2 sensor for cylinder bank 1.
The Code Reader does not perform O2 sensor tests, but
retrieves results from the most recently performed O2 sensor
tests from the on-board computer's memory. You may retrieve
O2 sensor test results for only one test of one sensor at any

Q:
Why can I not erase some codes?
A:
Unlike other codes which can be removed from the vehicle’s
control module, PERMANENT codes cannot. This holds true
regardless of the tool being used or color of the status LED display.
PERMANENT codes will automatically erase when the control
module no longer detects the fault that originally caused the code.
