>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the following harness connectors.

-

Harness connectors B208 and B32

-

Harness connectors B1 and M6

2. Check the continuity between the harness connectors.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the harness connectors B32 and B1.

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 CAN system type decision again.

YES (Past error)>>Error was detected in the main line between the driver seat control unit and the data link

connector.

NO

>> Repair the main line between the harness connector M6 and the data link connector.
