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. See
Preparation for Testing on page 14 for details.
ALWAYS observe safety precautions whenever working on a
vehicle. See Safety Precautions on page 1 for more information.
1. Turn the igniti
on 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.
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 1
80° 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. When the Code Reader’s cable
connector is properly connected to the
vehicle’s DLC, the unit automatically
turns ON.
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.
If replacing the fuse(s) does not correct the problem, consult
your vehicle’s repair manual to identify the proper computer
(PCM) fuse/circuit, and perform any necessary repairs before
proceeding.
