Diagnosis Procedure

INFOID:0000000010272938

1.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Disconnect the following harness connectors.

-

ECM

-

Chassis control module

4.

Check the continuity between the data link connector and the chassis control module harness connector.

Is the inspection result normal?

YES (Present error)>>Check CAN system type decision again.
YES (Past error)>>Error was detected in the main line between the data link connector and the chassis con-

trol module. 

NO

>> Repair the main line between the data link connector and the chassis control module.
