2 General Information
On-Board Diagnostics (OBD/OBDII)
The first generation of On-Board Diagnostics (called OBDI) was developed
by the California Air Resources Board (ARB) and implemented in 1988 to
monitor some of the emission control components on vehicles. As technology
evolved and the desire to improve the On-Board Diagnostic system increased,
a new generation of On-Board Diagnostic system was developed. This second
generation of On-Board Diagnostic regulations is called “OBDII.”
The OBDII system is designed to monitor emission control systems and key
engine components by performing either continuous or periodic tests of
specific components and vehicle conditions. When a problem is detected, the
OBDII system turns on a warning light on the vehicle instrument panel to alert
the driver typically by the phrase of “Check Engine” or “Service Engine Soon.”
The system will also store important information about the detected
malfunction so that a technician can accurately find and fix the problem. Here
below follow three pieces of such valuable information:
1) Whether the Malfunction Indicator Light (MIL) is commanded “on” or “off.”
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored.
3) Readiness Monitor status.
Diagnostic Trouble Codes (DTCs)
OBDII Diagnostic Trouble Codes are codes that are stored by the on-board
computer diagnostic system in response to a problem found in the vehicle.
These codes identify a particular problem and are intended to provide you
with a guide as to where a fault might be occurring within a vehicle. OBDII
Diagnostic Trouble Codes consist of a five-digit alphanumeric code. The first
letter identifies which control system sets the code. The four numbers provide
additional information on where the DTC originated and the operating
conditions that caused it to set. Here below is an example to illustrate the
structure of the digits:
4
Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is a
standardized 16-cavity connector where diagnostic scan tools interface with
the vehicle's on-board computer. The DLC is usually located 12 inches from
the center of the instrument panel (dashboard), under or around the driver’s
side for most vehicles. If the DLC is not located under the dashboard, a label
should be there telling the location. For some Asian and European vehicles,
the DLC is located behind the ashtray and the ashtray must be removed to
access the connector. If the DLC cannot be found, refer to the vehicle’s
service manual for the location.
5
OBDII Readiness Monitors
An important part of a vehicle’s OBDII system is the Readiness Monitors,
which are indicators used to find out if all of the emissions components have
been evaluated by the OBDII system. They run periodic tests on specific
systems and components to ensure that they are performing within the
allowable limits.
Currently, there are eleven OBDII Readiness Monitors (or I/M Monitors)
defined by the U.S. Environmental Protection Agency (EPA). Not all monitors
are supported by all vehicles and the exact number of monitors in any vehicle
depends on the motor vehicle manufacturer’s emissions control strategy.
Continuous Monitors — Some of the vehicle components or systems are
continuously tested by the vehicle’s OBDII system, while others are tested
only under specific vehicle operating conditions. The continuously monitored
components listed below are always ready:
1. Misfire
2. Fuel System
3. Comprehensive Components (CCM)
Once the vehicle is running, the OBDII system is continuously checking the
above components, monitoring key engine sensors, watching for engine
misfire, and monitoring fuel demands.
Non-Continuous Monitors — Unlike the continuous monitors, many
emissions and engine system components require the vehicle to be operated
under specific conditions before the monitor is ready. These monitors are
termed non-continuous monitors. For different ignition engine types, the
available monitors are different too.
6
The following monitors are to be used for spark ignition engines only:
EGR System
O
2
Sensors
Catalyst
Evaporative System
O
2
Sensor Heater
Secondary Air
Heated Catalyst
The following monitors are to be used for compression ignition engines only:
EGR System
NMHC Catalyst
NOx Aftertreatment
Boost Pressure System
Exhaust Gas Sensor
PM Filter
OBDII Monitor Readiness Status
OBDII systems must indicate whether or not the vehicle PCM’s monitor
system has completed testing on each component. Components that have
been tested will be reported as “Ready,” or “Complete,” meaning they have
been tested by the OBDII system. The purpose of recording readiness status
is to allow inspectors to determine if the vehicle’s OBDII system has tested
all the components and/or systems.
The power-train control module (PCM) sets a monitor to “Ready” or
“Complete” after an appropriate drive cycle has been performed. The drive
cycle that enables a monitor and sets readiness codes to “Ready” varies for
each individual monitor. Once a monitor is set as “Ready” or “Complete,” it
will remain in this state. A number of factors, including erasing of diagnostic
trouble codes (DTCs) with a scan tool or a disconnected battery, can result
7
in Readiness Monitors being set to “Not Ready.” Since the three continuous
monitors are constantly evaluating, they will be reported as “Ready” all of the
time. If the testing of a particular supported non-continuous monitor has not
been completed, the monitor status will be reported as “Not Complete” or “Not
Ready.”
In order for the OBD monitor system to become ready, the vehicle should be
driven under a variety of normal operating conditions. These operating
conditions may include a mix of highway driving and stop and go, city type
driving, and at least one overnight-off period. For specific information on
getting your vehicle’s OBD monitor system ready, please consult your vehicle
Owner’s Manual.
OBDII Definitions
Power-train Control Module (PCM) — OBDII terminology for the on-board
computer that controls engine and drive train.
Malfunction Indicator Light (MIL) — Malfunction Indicator Light (Service
Engine Soon, Check Engine) is a term used for the light on the instrument
panel. It is to alert the driver and/or the repair technician that there is a
problem with one or more of vehicle's systems and may cause emissions to
exceed federal standards. If the MIL illuminates with a steady light, it indicates
that a problem has been detected and the vehicle should be serviced as soon
as possible. Under certain conditions, the dashboard light will blink or flash.
This indicates a severe problem, and flashing is intended to discourage
vehicle operation. The vehicle onboard diagnostic system cannot turn the MIL
off until necessary repairs are completed or the condition no longer exists.
DTC — Diagnostic Trouble Codes (DTCs) identify which section of the
emission control system has malfunctioned.
Enabling Criteria — Also termed Enabling Conditions. They are the vehicle-
specific events or conditions that must occur within the engine before the
various monitors will set, or run. Some monitors require the vehicle to follow
a prescribed “drive cycle” routine as part of the enabling criteria. Drive cycles
vary among vehicles and for each monitor in any particular vehicle.
OBDII Drive Cycle — A specific mode of vehicle operation that provides
conditions required to set all the readiness monitors applicable to the vehicle
to the “ready” condition. The purpose of completing an OBDII drive cycle is
8
to force the vehicle to run its onboard diagnostics. Some form of a drive cycle
needs to be performed after DTCs have been erased from the PCM’s memory
or after the battery has been disconnected. Running through a vehicle’s
complete drive cycle will “set” the readiness monitors so that future faults can
be detected. Drive cycles vary depending on the vehicle and the monitor that
needs to be reset. For vehicle specific drive cycle, consult the vehicle Owner’s
Manual.
Freeze Frame Data — When an emissions related fault occurs, the OBDII
system not only sets a code but also records a snapshot of the vehicle
operating parameters to help identify the problem. This set of values is
referred to as Freeze Frame Data and may include important engine
parameters such as engine RPM, vehicle speed, air flow, engine load, fuel
pressure, fuel trim value, engine coolant temperature, ignition timing advance,
or closed loop status.
OBDII Modes of Operation
Here is a basic introduction to the OBDII communications protocol.
Mode Byte: The first byte in the stream is the mode number. There are 10
modes for diagnostic requests. The first byte in the response data bytes is
this same number plus 64. For example, a mode 1 request would have the
first data byte = 1, and the response would have the first data byte = 65. Here
is a brief description of the modes:
Mode $01 — Identifies the Power-train information and shows the current
data available to the scan tool. This data includes: DTC set, status of on-
board tests, and vehicle data such as engine RPM, temperatures, ignition
advance, speed, air flow rates, and closed loop status for fuel system.
Mode $02 — Displays Freeze Frame data. Same data as in mode 1, but it
was captured and stored when a malfunction occurred and a DTC was set.
Some of the PIDs for mode one are not implemented in this mode.
Mode $03 — Displays the type of power-train or emission related DTCs
stored by a 5-digit code identifying the faults. There may be more than one
response message if there are more trouble codes fit in the data bytes of the
response message, or if there are more than one ECU responding.
9
Mode $04 — Used to clear DTCs and freeze frame data. This clears all
diagnostic trouble codes that may be set including freeze frame data and
readiness monitors.
Mode $05 — Displays oxygen sensor test results. This mode displays the
oxygen sensor monitor screen and the test results gathered about the oxygen
sensor.
There are nine terms available for diagnostics:
1. $01 Rich-to-Lean O
2
sensor threshold voltage.
2. $02 Lean-to-Rich O
2
sensor threshold voltage.
3. $03 Low sensor voltage threshold for switch time measurement.
4. $04 High sensor voltage threshold for switch time measurement.
5. $05 Rich-to-Lean switch time in ms.
6. $06 Lean-to-Rich switch time in ms.
7. $07 Minimum voltage for test.
8. $08 Maximum voltage for test.
9. $09 Time between voltage transitions in ms.
Mode $06 — Non-continuously Monitored Systems test results. There are
typically a minimum value, a maximum value, and a current value for each
non-continuous monitor. This data is optional, and it is defined by a given
vehicle maker if it’s used.
Mode $07 — A request for DTCs (pending) from Continuously Monitored
Systems after a single driving cycle has been performed to determine if repair
has fixed a problem. This is used by service technicians to verify whether
repair was performed properly after diagnostic trouble codes are cleared.
Mode $08 — This special Control Mode requests control of the on-board
system, test, or component bi-directionally (where applicable). The mode is
manufacturer-specific.
10
Mode $09 — Reports vehicle information. This information includes vehicle
VIN number and calibration information stored in the vehicle ECUs.
Mode $0A — Requests Emissions-Related Diagnostic Trouble Codes with
Permanent Status. This mode is required for all emissions-related DTCs. The
presence of permanent DTCs during an inspection without the MIL
illuminated is an indication that a proper repair was not verified by the on-
board monitoring system.

Vehicle Coverage
The AutoLink
AL549 OBDII Scanner is specially designed to work with all
OBDII compliant vehicles, including those equipped with Control Area
Network (CAN) protocol. The EPA requires all domestic, Asian and European
vehicles, 1996 and newer vehicles (including light trucks), sold in the United
States must be OBDII compliant.
A small number of 1994 and 1995 model year gasoline vehicles are OBDII
compliant. To verify if a 1994 or 1995 vehicle is OBDII compliant, check the
Vehicle Emissions Control Information (VECI) Label which is located under
the hood or by the radiator of most vehicles. If the vehicle is OBDII compliant,
15
the label will designate “OBDII Certified.” Additionally, government
regulations mandate that all OBDII compliant vehicles must have a “common”
sixteen-pin DLC.
For your vehicle to be OBDII compliant, it must have a 16-pin DLC under the
dash and the Vehicle Emission Control Information Label must state that the
vehicle is OBDII compliant.
In addition to OBDII diagnosis, the AL549 scan tool also supports the ABS
diagnostics function, dealing with more than 20 US, Asian and European
vehicles, including Toyota, Honda, Benz, BWM, Ford, GM, Volkswagen, Audi,
Chrysler, Hyundai, Infiniti, Jaguar, Kia, Land Rover, Lexus, Mazda, Mini,
Scion, Volvo, Dodge, Lincoln, Acura, and Nissan.
Product Troubleshooting
This section describes problems that may be encountered while using the
scan tool.

Ensure the scan tool’s OBDII connector is securely connected to the
vehicle’s DLC.
Verify that the vehicle is OBDII compliant.
Turn the ignition off and wait for about 10 seconds. Turn the ignition on
again and continue the testing.
Verify the control module is not defective.
Operating Error
If the scan tool freezes, then an exception occurs or the vehicle’s ECU is too
slow to respond to requests. You need to do the following steps to reset the
tool:
Reset the scan tool.
16
Turn the ignition off and wait for about 10 seconds. Turn the ignition on
again and continue the testing.
Scan Tool Does Not Power Up
If the scan tool will not power up or operates incorrectly, do the following steps:
Check if the scan tool’s OBDII connector is securely connected to the
vehicle’s DLC.
Check if the DLC pins are bent or broken. Clean the DLC pins if
necessary.
Check the vehicle battery to make sure it is still good with at least 8.0
volts.

4 OBDII Diagnostics
The OBDII Diagnostics function is a fast-access option that allows you to
carry out a quick test on the engine system of OBDII vehicles.
When more than one vehicle control module is detected by the scan tool,
you will be prompted to select the module with retrievable data. The Power
train Control Module (PCM) and Transmission Control Module (TCM) are
the most commonly scanned modules.
IMPORTANT
DO NOT connect or disconnect the scan tool while the ignition is on or the
engine is running.
1) Turn the ignition off.
2) Locate the vehicle’s 16-pin Data Link Connector (DLC).
3) Plug the scan tool into the vehicle’s DLC.
4) Turn the ignition on. Engine can be off or running.
5) Turn on the scan tool. From the Main Screen, use the UP/DOWN scroll
button and LEFT/RIGHT scroll button to select OBDII/EOBD.
Figure 4-1 Main Screen
18
6) Press the OK button and wait for the Menu to display. The tool will
display OBDII protocols and the vehicle information when the vehicle’s
communication protocol is detected.
If the scan tool has failed to communicate with the vehicle’s ECU
(Engine Control Unit) more than three times, a “LINKING ERROR!”
message appears on the tool.
Verify the ignition is ON.
Check if the scan tool’s OBDII cable is securely connected to
the vehicle’s DLC.
Verify that the vehicle is OBDII compliant.
Turn the ignition off and wait for about 10 seconds. Turn the
ignition back on and repeat step 5.
If the “LINKING ERROR!” message continues to display, contact
your local distributor or customer service for assistance.
7) View a summary of the system status (MIL status, DTC counts, monitor
status) on screen. Wait a moment or press any key for the Diagnostic
Menu to appear.
Figure 4-2 System Status Screen
If more than one module is detected, you will be prompted to select
a module before testing.
Use the UP/DOWN scroll button to select a module and press the
OK button to confirm.
Read Codes
The Read Codes function can be performed with the key on engine off
(KOEO) or with the key on engine running (KOER).
19
Stored Codes are also known as “hard codes,” which are fault codes,
or trouble codes that have been stored in the vehicle computer memory
because the faults have reoccurred for more than a specified amount of
key-cycles. These codes will cause the control module to illuminate the
malfunction indicator light (MIL) when emissions-related faults occur.
Pending Codes are also referred to as “maturing codes” or “continuous
monitor codes.” They indicate problems that the control module has
detected during the current or last driving cycle but are not as yet
considered serious. Pending Codes will not turn on the malfunction
indicator light (MIL). If the fault does not occur within a certain number
of warm-up cycles, the code clears from memory.
Permanent Codes are DTCs that are "confirmed" and are retained in
the non-volatile memory of the vehicle’s computer until the appropriate
monitor for each DTC has determined that the malfunction is no longer
present and is not causing the MIL. Permanent DTCs are stored in non-
volatile memory and cannot be erased by any diagnostics service or by
disconnecting power to ECU.
1) From the Diagnostic Menu screen, use the UP/DOWN scroll button to
select Read Codes and press the OK button.
Figure 4-3 Diagnostic Menu Screen
2) Use the UP/DOWN scroll button to select OBD Codes or Enhanced
Codes and press the OK button.

“Freeze Frame” data and manufacturer-specific enhanced data. Further,
the I/M Readiness Monitor Status for all vehicle monitors is reset to Not
Ready or Not Complete status. Do not erase the codes before repairs
or services have been performed.
2. Even if deleted, codes will again display if the underlining fault causing
the code is not addressed.
This function is performed with key on, engine off (KOEO). Do not start
the engine.

I/M Readiness
I/M Readiness function is used to check the operations of the Emission
System on OBDII compliant vehicles. It is an excellent function to use prior
to having a vehicle inspected for state emissions compliance.
NOTE
Clearing trouble codes also clears the readiness status for the individual
emission system readiness tests. In order to reset these monitors, the
vehicle must be driven through a complete drive cycle with no trouble codes
in memory. Amount of time needed for reset vary by vehicle.
33
Some latest vehicle models may support two types of I/M Readiness tests:
A. Since DTCs Cleared — indicates status of the monitors since the DTCs
are erased.
B. This Driving Cycle — indicates status of monitors since the beginning
of the current driving cycle.
An I/M Readiness Status result of “NO” does not necessarily indicate that
the vehicle being tested will fail the state I/M inspection. In some states, one
or more such monitors may be allowed to be “Not Ready” to pass the
emissions inspection.
There are two ways to retrieve I/M readiness status.
Retrieve I/M Readiness status with One-Click I/M
Readiness Key
Press One-Click I/M Readiness Key to retrieve the I/M readiness status.
The screen will display as below. The LED colors and the audio tones
indicate readiness status.
Figure 4-26 I/M Readiness Screen
The green, yellow and red LEDs provide a quick way to help you determine
if a vehicle is ready for an Emission Test.
OK — indicates that a particular monitor being checked has completed
its diagnostic testing.
INC — indicates that a particular monitor being checked has not
completed its diagnostics test.
N/A — the monitor is not supported on the vehicle.
34
The LED and audio tone are interpreted as below:
LED Interpretation
GREEN LED — indicates that engine systems are “OK” and operating
normally (the number of Monitors supported by the vehicle that have
run and performed their self-diagnostics test is within the allowed limit.
MIL is off). There are neither stored nor pending DTCs. The vehicle is
ready for an Emissions Testing, and there is a good possibility that it
can be certified.
YELLOW LED — with MIL off, there may be three possible conditions
to cause the yellow LED to light.
If a “Stored” DTC is causing the Yellow LED to light, it is still
possible that the vehicle will be allowed to be tested for emissions
and certified.
If a “Pending” DTC is causing the Yellow LED to light, it is still
possible that the vehicle will be allowed to be tested for emissions
and certified.
The Yellow LED will also light if the monitors do not complete their
tests. Each state’s emissions standards differ on the number of
tested monitors needed to meet vehicle emissions compliance.
NOTE
Confer with your automotive technician about the status results of each
monitor to determine if the vehicle is ready for your state’s emissions testing.
RED LED — indicates there is a problem with one or more of the
vehicle’s system. The test of a vehicle resulting a lit red LED is not ready
for an Emissions Testing. The red LED is also an indication that there
are DTCs present. The MIL lamp on the vehicle’s instrument panel will
light steadily. The problem that is causing the red LED to light must be
repaired before an Emissions Testing. It is also suggested that the
vehicle be inspected/repaired before driving the vehicle further.
If the RED LED lights, there is a problem present in the system(s). In
this case, you have the following options:
Repair the vehicle yourself. Ensure that you proceed by reading the
vehicle service manual and following all procedures and
recommendations.
35
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 undergoes Emissions Testing.

On-Board Monitor Test
The On-Board Monitor Test is useful after servicing or erasing a vehicle’s
control module memory. The On-Board Monitor Test for non-CAN-equipped
vehicles retrieves and displays test results for emissions-related power train
components and systems that are not continuously monitored. The On-
Board Monitor Test for CAN-equipped vehicles retrieves and displays test
results for emissions-related power train components and systems that are
continuously monitored or not.
The scan tool allows access to the results of on-board diagnostic monitoring
tests for specific components/systems. The vehicle manufacturer is
responsible for assigning "Manufacturer Defined Test IDs" and Component
38
IDs for tests of different systems and components. The advanced feature of
this scan tool enables you to read the definition of an On-Board Diagnostic
Monitor ID.

5 ABS Diagnosis
The ABS — Anti-lock Braking System in most vehicles is made up of an
electronic hydraulic pump of two to four Wheel Speed Sensors (WSS), a G-
force sensor, a Vehicle Speed Sensor, and an ABS Control Module (EBCM).
The EBCM is constantly monitoring the WSS, the Vehicle Speed Sensor, and
the G-sensor.
Diagnosing an ABS problem should always start with a visual inspection of
all brake components. Then you will need to retrieve ABS DTCs to tell you
where the problem is.
The ABS diagnostic function is used to retrieve and clear codes from the
vehicle’s Anti-lock Braking System. It also provides the definition of each
code to help diagnosing problems within the system that may cause the
Malfunction Indicator Light (MIL) to turn on.
IMPORTANT
Autel accepts no responsibility for any accident or injury arising from servicing
the ABS system. When interpreting DTCs retrieved from the vehicle, always
follow the manufacturer’s recommendation for repair.
NOTE
