Diagnosis Procedure

INFOID:0000000006179138

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

-

Differential lock control unit

-

Harness connectors B37 and B200

4. Check the continuity between the differential lock control unit harness connector and the harness connec-

tor.

Is the inspection result normal?

YES (Present error)>>Check the following items again.

• Decision of CAN system type.

• Not received CONSULT-III data [SELF-DIAG RESULTS, CAN DIAG SUPPORT MNTR (“ECU

list” included)].

• Not copied from on-board diagnosis.

• Procedure for detecting root cause.

YES (Past error)>>Error was detected in the main line between the differential lock control unit and the driver

seat control unit.

NO

>> Repair the main line between the differential lock control unit and the harness connector B37.
