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 18
for details.
ALWAYS observe safety precautions whenever working on a
vehicle. See Safety Precautions on page 3 for more
information.
1. Turn the ignition OFF.
2. Locate the vehicle's 16-pin Data Link
Connector (DLC). See page 21 for
connector location.
Some DLCs have a plastic cover
that must be removed before
connecting the CanOBD2&1 Scan
Tool cable connector.
If the CanOBD2&1 Scan Tool is ON,
turn it OFF by pressing the
POWER/LINK button BEFORE
connecting the CanOBD2&1 Scan
Tool to the DLC.
3. Connect the OBD II Cable to the CanOBD2&1 Scan Tool, then
connect to the vehicle’s DLC.
� 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
pins on the CanOBD2&1 Scan
Tool’s DLC and on the vehicle’s
DLC.
4. When the CanOBD2&1 Scan Tool’s
cable connector is properly connected
to the vehicle’s DLC, the unit automatically
turns ON, and the display shows
instructions for linking to the vehicle’s
on-board computer.
