YES

>> GO TO 3.

NO

>> Repair the main line between the data link connector and the harness connector M7.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check the continuity between the harness connector terminals.

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 driver seat

control unit. 

NO

>> Repair the main line between the harness connector B1 and the driver seat control unit.
