- Harness connectors B69 and M40
2. Check the continuity between the differential lock control unit harness connector and the harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair the main line between the differential lock control unit and the harness connector B69.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check the continuity between the harness connector and the data link connector.





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 data link connector.
NO - Repair the main line between the harness connector M40 and the data link connector.
