CODE RETRIEVAL PROCEDURE
22 OBD2
Retrieving and using Diagnostic Trouble Codes (DTCs) for
troubleshooting vehicle operation is only one part of an
overall diagnostic strategy.
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 BEFORE YOU BEGIN on page 20 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 5 for
connector location.
Some DLCs have a plastic cover
that must be removed before
connecting the Scan Tool cable
connector.
If the Scan Tool is ON, turn it OFF
by pressing the POWER/LINK
button BEFORE connecting the
Scan Tool to the DLC.
3.
Connect the Scan Tool 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 Scan Tool. Refer to your vehicle’s service manual to properly
check the vehicle’s DLC.
4.
When the 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.
