
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from
all moving or hot engine parts.
Operate the vehicle in a well ventilated work area: Exhaust gases
are poisonous.
Put blocks in front of the drive wheels and never leave the vehicle
unattended while running tests.
Use extreme caution when working around the ignition coil,
distributor cap, ignition wires and spark plugs. These
components create hazardous voltages when the engine is
running.
Put the transmission in PARK (for automatic transmission) or
NEUTRAL (for manual transmission) and make sure the parking
brake is engaged.
Keep a fire extinguisher suitable for gasoline/chemical/ electrical
fires nearby.
Don‟t connect or disconnect any test equipment while the
ignition is on or the engine is running.
Keep the scan tool dry, clean, free from oil/water or grease. Use a
mild detergent on a clean cloth to clean the outside of the scan
tool, when necessary.

2. General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) 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 "OBD II".
The OBD II 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 OBD II system turns on a warning lamp (MIL)
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.
2.2 Diagnostic Trouble Codes (DTCs)
OBD II 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 area and are
intended to provide you with a guide as to where a fault might be
occurring within a vehicle. OBD II Diagnostic Trouble Codes
consists of a five-digit alphanumeric code. The first character, a letter,
identifies which control system sets the code. The other four
characters, all 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:

2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the
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 (dash),
under or around the driver‟s side for most vehicles. If Data Link
Connector is not located under dashboard, a label should be there
telling location. For some Asian and European vehicles, the DLC is
located behind the ashtray and the ashtray must be removed to access
3
the connector. If the DLC cannot be found, refer to the vehicle‟s
service manual for the location.
2.4 OBD II Readiness Monitors
An important part of a vehicle‟s OBD II system is the Readiness
Monitors, which are indicators used to find out if all of the emissions
components have been evaluated by the OBD II system. They are
running periodic tests on specific systems and components to ensure
that they are performing within allowable limits.
Currently, there are eleven OBD II 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 OBD II 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 OBD II 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
4
operated under specific conditions before the monitor is ready. These
monitors are termed non-continuous monitors. For different ignition
type engines, the available monitors are different too.
The following monitors are to be used for spark ignition engines
only:
1)
2)
3)
4)
5)
6)
7)
EGR System
O2 Sensors
Catalyst
Evaporative System
O2 Sensor Heater
Secondary air
Heated Catalyst
The following monitors are to be used for compression ignition
engines only:
1)
2)
3)
4)
5)
6)
EGR System
NMHC Catalyst
NOx aftertreatment
Boost pressure system
Exhaust gas sensor
PM filter
2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle‟s 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 OBD II system.
The purpose of recording readiness status is to allow inspectors to
determine if the vehicle‟s OBD II 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”
5
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 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 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.
2.6 OBD II Definitions
Power-train Control Module (PCM) -- OBD II 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 can not turn
the MIL off until necessary repairs are completed or the condition no
longer exists.
DTC -- Diagnostic Trouble Codes (DTC) that 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
6
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.
OBD II 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 OBD II drive cycle is 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‟s Owner‟s Manual.
Freeze Frame Data -- When an emissions related fault occurs, the
OBD II system not only sets a code but also records a snapshot of the
vehicle operating parameters to help in identifying 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.
2.7 OBD II Modes of Operation
Here is a basic introduction to the OBD II communication protocol.
Mode byte: The first byte in the stream is the mode number. There
are 9 modes for diagnostic requests, so this first byte is from 1 to 9.
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 Powertrain information and shows
current data available to the scan tool. This data includes: DTCs
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.
7
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 powertrain 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 than
will fit in the data bytes of the response message, or if there are more
than one ECU computer responding.
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 - Oxygen Sensor Test Results. This mode displays the
oxygen sensor monitor screen and the test results gathered about the
oxygen sensor.
There are ten numbers available for diagnostics:
1.
2.
3.
4.
5.
6.
7.
8.
9.
$01 Rich-to-Lean O2 sensor threshold voltage
$02 Lean-to-Rich O2 sensor threshold voltage
$03 Low sensor voltage threshold for switch time
measurement
$04 High sensor voltage threshold for switch time
measurement
$05 Rich-to-Lean switch time in ms
$06 Lean-to Rich switch time in ms
$07 Minimum voltage for test
$08 Maximum voltage for test
$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 make if it‟s used.
Mode $07 - 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
8
used by service technicians to verify repair was performed properly
and after clearing diagnostic trouble codes.
Mode $08 - This Special Control Mode requests control of the
on-board system, test, or component bi-directionally (where
applicable). This mode is manufacturer specific.
Mode $09 - Reports vehicle information. This information includes
vehicle VIN number and calibration information stored in the vehicle
ECUs.
Mode $0A -- Request Emission-Related Diagnostic Trouble
Codes with Permanent Status. This mode is required for all
emissions-related DTCs. The presence of permanent DTCs at an
inspection without the MIL illuminated is an indication that a proper
repair was not verified by the on-board monitoring system.

3.9 Vehicle Coverage
The AutoLink AL319 OBDII/EOBD Scanner is specially designed
to work with all OBD II compliant vehicles, including those equipped
with next-generation protocol -- Control Area Network (CAN). It is
required by EPA that all 1996 and newer vehicles (cars and light
trucks) sold in the United States must be OBD II compliant and this
includes all Domestic, Asian and European vehicles.
A small number of 1994 and 1995 model year gasoline vehicles are
OBD II compliant. To verify if a 1994 or 1995 vehicle is OBD II
21
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 OBD II compliant, the label will designate
“OBD II Certified”. Additionally, Government regulations mandate
that all OBD II compliant vehicles must have a “common”
sixteen-pin Data Link Connector (DLC).
For your vehicle to be OBD II compliant it must have a 16-pin DLC
(Data Link Connector) under the dash and the Vehicle Emission
Control Information Label must state that the vehicle is OBD II
compliant.
3.10 Product Troubleshooting
This part describes problems that you may encounter while using the
scan tool.
Vehicle Linking Error
A communication error occurs if the scan tool fails to communicate
with the vehicle‟s ECU (Engine Control Unit). You need to do the
following to check up:
 Verify that the ignition is ON.
 Check if the scan tool‟s OBD II connector is securely
connected to the vehicle‟s DLC.
 Verify that the vehicle is OBD2 compliant.
 Turn the ignition off and wait for about 10 seconds. Turn the
ignition back to on 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 (Engine Control Unit) is too slow to respond to requests. You
need to do the following to reset the tool:
 Reset the scan tool.
 Turn the ignition off and wait for about 10 seconds. Turn the
ignition back to on and continue the testing.
22
Scan tool doesn’t power up
If the scan tool won‟t power up or operates incorrectly in any other
way, you need to do the following to check up:
 Check if the scan tool‟s OBD II 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 vehicle battery to make sure it is still good with at least 8.0
volts.
LED lamps not working
If you turn on the scan tool and perform the I/M Readiness test but
the LED lamps are not working, there may be several possible causes,
including bad connection and ignition off. In this case, follow these
steps to check the scan tool.

Make sure the OBD II cable is connected to the DLC securely.

Verify the ignition key is in the KOER position.

Run the LED Test in the System Setup menu. (see 3.7 System
Setup). If the scan tool did not pass this test, there is a problem
with the LED lamp. Please contact Autel Tech Support or your
local selling agent.

4.1 Reading Codes
 Reading Codes can be done with the key on engine off (KOEO)
or with the key on engine running (KOER).
 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
25
the control module to illuminate the malfunction indicator light
(MIL) when emission-related fault occurs.
 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 considered serious yet. Pending Codes will not
turn on the malfunction indicator lamp (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 computer until the
appropriate monitor for each DTC has determined that the
malfunction is no longer present and is not commanding the
MIL on. Permanent DTC shall be stored in non-volatile
memory and may not be erased by any diagnostic services or by
disconnecting power to ECU.

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 the system has been checked completely
by a technician.
NOTE: Erasing codes does not mean that trouble codes in ECU
have been eliminated completely. As long as there is fault with the
vehicle, the trouble codes keep on presenting.
 This function is performed with key on engine off (KOEO). Do
not start the engine.

4.5 Retrieving I/M Readiness Status
I/M Readiness function is used to check the operations of the
Emission System on OBD2 compliant vehicles. It is an excellent
function to use prior to having a vehicle inspected for
compliance to a state emissions program.
CAUTION - By clearing trouble codes you also clear the readiness
status for the individual emission system readiness tests. In order
to reset these monitors, the vehicle must be driven through a
32
complete drive cycle with no trouble codes in memory. Times for
reset vary depending on vehicle.
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 Drive Cycle - indicates status of monitors since the
beginning of the current drive 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. For some states, one or more such monitors may be
allowed to be “Not Ready” to pass the emissions inspection.
 “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 diagnostic testing.
 “N/A” -- The monitor is not supported on that vehicle.
There are two ways to retrieve I/M readiness status.
A. Retrieve I/M Readiness status with One-Click I/M
Readiness Key
By simply pressing the One-Click I/M Readiness Key, you can
retrieve the I/M readiness status. The screen will show as below.
(Figure 4.14) According to different readiness status, the color LEDs
will illuminate and different audio tones will be heard.
33
Figure 4.14
“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 diagnostic testing.
“N/A”
-- The monitor is not supported on the vehicle.
The green, yellow and red LEDs provide a quick way to help you
determine if a vehicle is ready for an Emission Test.
The LED and audio tone indications are interpreted as below:
LED Interpretation
1)
GREEN LED – Indicates that engine systems are “OK” and
operating normally (the number of Monitors supported by the
vehicle which have run and performed their self-diagnostic
testing is in the allowed limit. MIL is off. ).There are no stored
and pending DTCs. The vehicle is ready for an Emissions Test,
and there is a good possibility that it can be certified.
2)
YELLOW LED – With MIL off, there may be three possible
conditions to cause the yellow LED to light.
34

If a “Stored” Diagnostic Trouble Code 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” Diagnostic Trouble Code 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 the illumination of the Yellow LED is being caused by
monitors that have not completed their diagnostic testing,
then the issue of the vehicle being ready for an Emissions
Test depends on the emissions regulations and laws of your
local area.
NOTE: From the code retrieval procedure, determine the status of
each Monitor. Take this information to an emissions professional to
determine (based on your test results) if your vehicle is ready for an
Emissions Test.
3)
RED LED – Indicates there is a problem with one or more of
the vehicle‟s system. A vehicle displaying a red LED is
definitely not ready for an Emissions Test. The red LED is also
an indication that there are DTCs present. The MIL lamp on the
vehicle‟s instrument panel will light steady. The problem that is
causing the red LED to light must be repaired before an
Emissions Test 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.
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 is ready for an Emissions Test.
Audio Tone Interpretation
The audio tone is configured according to the I/M Readiness Status.
This function is invaluable when performing diagnostics and driving
at the same time, or working in bright areas where LED illumination
alone is not sufficient.
Different audio tone with different LED light indicates different I/M
Readiness Status.

5. Ready Test
This function can be used as a convenient readiness test tool by
automotive technicians to determine if the tested vehicle is
ready for an emission test. By visual and audible indication,
you will learn a vehicle’s monitors readiness.
5.1 General Information
Repairs to the emissions-control systems of a 1996 or newer vehicle
cause the vehicle‟s computer (ECU) memory to be cleared. The
vehicle must go through a drive cycle to allow the ECU to perform a
series of tests to ensure that the repair was successful, and before a
state mandated emissions test can be conducted. But how will you
know when it is ready?
With this scan tool, you don‟t have to drive around endlessly and
continuously coming back to the repair shop for retest if all required
tests by the ECU are completed. And you could also do a quick check
of the vehicle to determine if it is ready to receive an emission test
without the hassle of connecting your vehicle to the analyzer or
having to use a complicated scan tool.
In the following cases, this function is especially useful.

You bought a used car and the check engine light had been
cleared to mask potential problems.

You disconnected the battery for tune-ups and other engine
repairs, dead battery replacement, car radio installation and car
alarm installation.

You used a scan tool to clear the DTCs.

Your car has been sent to repair.
5.2 Test tool application
41
The purpose of this function is to indicate 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 emission system. All data
shows on one screen, which provides a simple profile of vehicle at a
glance, saving diagnosis time and improving technician productivity.

Use the SCROLL button to select Ready Test from Main
Screen (Figure 5.1), and press the ENTER/Exit button.
Figure 5.1
As post-repair diagnostic tool
This function can be used (after the vehicle has done any
emission-related repairs) to confirm that the repair has been
performed successfully.
After repairs, some drive cycles are required to reset the monitoring
systems. Drive cycles vary among vehicles and for each monitor in
any particular vehicle.
Use the following procedure to check if the repair has been done
correctly:
1)
Connect the scan tool to the vehicle‟s DLC and erase the DTC(s)
from the vehicle‟s computer memory. (see 4.2 erasing codes)
42
2)
After the erase procedure is performed, status of most monitors
will be changed. Leave the scan tool connected to the vehicle,
and select Ready Test from Main Screen.
3)
Keep on driving the car till the scan tool notifies you safely with
color LEDs and audible tone that the drive cycle has been
completed and the vehicle is ready, eliminating drive cycle
guesswork and confirming readiness status.
4)
If the GREEN LED lights and two long beeps are heard, your
vehicle is ready and the repair work is confirmed.
5)
If the RED LED lights, your vehicle is not ready and the repair
work is unsuccessful.
As pre-check diagnostic tool
Prior to having a vehicle inspected for compliance to a state
emissions test, you could use this function to check the readiness
status first by yourself.
1)
While the scan tool connected to the vehicle, select Ready Test
from Main Screen. Drive the car till the scan tool notifies you
safely with color LEDs and audible tone if your vehicle is ready
to conduct state emission test.
2)
If the GREEN LED lights and two long beeps are heard, your
vehicle is ready and there is a good possibility that it can be
certified.
3)
If the RED LED lights, your vehicle is not ready and must be
repaired before an emissions test can be performed.
IMPORTANT: If you are driving the vehicle to perform a drive
cycle ALONE, please set the Status Beep On (see 3.7 System Setup).
By listening to the beep, you will learn when the monitors have run
and completed the diagnostic testing. NEVER try to drive and
operate the scan tool at the same time!
43
NOTE: This function reads off the real time data of
emission-related monitoring systems readiness status. Once the scan
tool has finished other operations, for example, clearing trouble
codes, the I/M Readiness Monitor Status program resets status of all
the monitors to “INC” condition. In order to set these monitors to a
Ready status, the vehicle must be driven through a complete drive
cycle. Times for reset vary depending on vehicle. Please refer to
your vehicle’s service manual for drive cycle information.
NOTE: In this function, only ENTER/Exit button is available. The
other buttons are disabled to prevent misoperation.
5.3 LED and Tone Interpretation
Select Ready Test from the Main Screen and the screen shows as
below, including applicable monitors status, MIL state, Ignition type,
DTCs (stored one and pending one).
Figure 5.2
If the scan tool is idle, it will show the result immediately. If it is busy,
it will wait till the current procedure finished. After viewing the status,
press ENTER/Exit button to exit.
“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 diagnostic testing.
44
“N/A”
-- The monitor is not supported on the vehicle.
The LED and audio tone indications are interpreted as below:
LED Interpretation
The green and red LEDs provide an easy way to check if
emission-related monitoring systems complete their self-diagnostic
testing.
1)
GREEN LED – Your vehicle is Ready. Indicates that engine
systems are “OK” and operating normally (the number of
Monitors supported by the vehicle which have run and
performed their self-diagnostic testing is in the allowed limit).
2)
RED LED –Your vehicle is Not Ready. Indicates that the
number of Monitors supported by the vehicle which have run
and performed their self-diagnostic testing is out of the allowed
limit.
Audio Tone Interpretation
The audio tone could be configured according to the I/M Readiness
Status. This function is invaluable when performing diagnostics and
driving at the same time, or working in bright areas where LED
illumination alone is not sufficient.
