SAFETY FIRST!
This manual describes common test procedures used
by experienced service technicians. Many test procedures
require precautions to avoid accidents that can result in
personal injury, and/or damage to your vehicle or test
equipment. Always read your vehicle's service manual and
follow its safety precautions before and during any test or
service procedure. ALWAYS observe the following general
safety precautions:
When an engine is running, it produces carbon monoxide,
a toxic and poisonous gas. To prevent serious injury or
death from carbon monoxide poisoning, operate the
vehicle ONLY in a well-ventilated area.
To protect your eyes from propelled objects as well as hot
or caustic liquids, always wear approved safety eye
protection.
When an engine is running, many parts (such as the
coolant fan, pulleys, fan belt etc.) turn at high speed. To
avoid serious injury, always be aware of moving parts.
Keep a safe distance from these parts as well as other
potentially moving objects.
Engine parts become very hot when the engine is running.
To prevent severe burns, avoid contact with hot engine
parts.
Before starting an engine for testing or troubleshooting,
make sure the parking brake is engaged. Put the
transmission in park (for automatic transmission) or
neutral (for manual transmission). Block the drive wheels
with suitable blocks.
Connecting or disconnecting test equipment when the
ignition is ON can damage test equipment and the
vehicle's electronic components. Turn the ignition OFF
before connecting the Code Reader to or disconnecting
the Code Reader from the vehicle’s Data Link Connector
(DLC).
To avoid personal injury, instrument damage and/or
damage to your vehicle.

To prevent damage to the on-board computer when taking
vehicle electrical measurements, always use a digital
multimeter with at least 10 megOhms of impedance.
Fuel and battery vapors are highly flammable. To prevent
an explosion, keep all sparks, heated items and open
flames away from the battery and fuel / fuel vapors. DO
NOT SMOKE NEAR THE VEHICLE DURING TESTING.
Don't wear loose clothing or jewelry when working on an
engine. Loose clothing can become caught in the fan,
pulleys, belts, etc. Jewelry is highly conductive, and can
cause a severe burn if it makes contact between a power
source and ground.

The I/M Monitor Status icons are associated with INSPECTION
and MAINTENANCE (I/M) READINESS STATUS. Some states
require that all vehicle Monitors have run and completed their
diagnostic testing before a vehicle can be tested for Emissions
(Smog Check). A maximum of fifteen Monitors are used on OBD2
systems. Not all vehicles support all fifteen Monitors. When the
Code Reader is linked to a vehicle, only the icons for Monitors
that are supported by the vehicle under test are visible on the
display.
3. Link icon - Indicates whether or not the Code Reader is
communicating (linked) with the vehicle's on-board computers.
When visible, the Code Reader is communicating with the
computers. If the Link icon is not visible, the Code Reader is not
communicating with the computers.
4. Vehicle icon - Indicates whether or not the Code Reader is
being properly powered through the vehicle's Data Link Connector
(DLC). A visible icon indicates that the Code Reader is being
powered through the vehicle's DLC connector.
5. MIL icon - Indicates the status of the Malfunction Indicator Lamp
(MIL). The MIL icon is visible only when a DTC has commanded the
MIL on the vehicle's dashboard to light.

CODE RETRIEVAL PROCEDURE
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.
ALWAYS observe safety precautions whenever working on a
vehicle. See SAFETY FIRST! on page 1 for more information.
1. Turn the ignition off.
2. Locate the vehicle's 16-pin Data Link
Connector (DLC).
3. Connect the Code Reader’s 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.
After the Code Reader’s test
connector is properly connected to
the vehicle's DLC, the Vehicle icon
should display to confirm a good
power connection.
4. Turn the ignition on. DO NOT start the
engine.
5. The Code Reader will automatically link to the vehicle’s computer(s).
If the LCD display is blank, it indicates there is no power at the
vehicle's DLC. Check your fuse panel and replace any burned-
out fuses.
If replacing the fuse(s) does not correct the problem, see your
vehicle's repair manual to locate the proper computer (PCM)
fuse/circuit. Perform any necessary repairs before continuing.
After 4-5 seconds, the Code Reader will retrieve and display
any Diagnostic Trouble Codes that are in the vehicle's computer
memory.

If Error is shown on the Code
Reader’s LCD display, it indicates
there is a communication problem.
This means that the Code Reader is
unable to communicate with the
vehicle's computer. Do the following:
- Turn the ignition key off, wait 5
seconds and turn the key back on
to reset the computer.
- Make sure your vehicle is OBD2 compliant.
6. Read and interpret the Diagnostic Trouble Codes using the LCD
display and the green, yellow and red LEDs.
The green, yellow and red LEDs are used (with the LCD
display) as visual aids to make it easier for the user to
determine engine system conditions.
Green LED - Indicates that all
engine systems are "OK" and
running normally. All monitors on the
vehicle are active and are performing
their diagnostic testing, and no
trouble codes are present. The
message 0 DTC will show on the
Code Reader’s LCD display for
further confirmation.
Yellow LED - Indicates one of the
following conditions:
PENDING CODE PRESENT - If the
yellow LED is lit, it may indicate the
existence of a pending code. Check
the Code Reader’s LCD display for
confirmation. A pending code is
confirmed by the presence of a
numeric code and the word PENDING
on the Code Reader’s LCD display. If
no pending code is shown, the yellow
LED indicates Monitor Status (see the
following).
MONITOR STATUS - If the Code
Reader’s LCD display shows the
message 0 DTC (indicating there are
no DTCs present in the vehicle's
computer), but the yellow LED is lit, it
indicates a "Monitor Has Not Run"
status. This means that some of the
Monitors on the vehicle have not yet
finished their diagnostic self-testing.
This condition is confirmed by one or
more blinking Monitor icons on the
LCD display. A blinking Monitor icon means the Monitor has not
yet run and finished its diagnostic self-testing. All Monitor icons
that are solid have completed their diagnostic self-testing.
