>> GO TO 2.
NO
>> Repair the terminal and connector.
2.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the following harness connectors.
-
IPDM E/R
-
Harness connectors E7 and M69
2. Check the continuity between the IPDM E/R harness connector and the harness connector.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair the main line between the IPDM E/R and the harness connector E7.
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 M69 and the data link connector.
