YES
>> GO TO 3.
NO
>> Repair the main line between the IPDM E/R and the harness connector E105.
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 IPDM E/R and the data link connector.
NO
>> Repair the main line between the harness connector M77 and the data link connector.
