YES

>> GO TO 3.

NO

>> Repair the main line between the IPDM E/R and the harness connector E107.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the harness connectors B3 and M21.

2. Check the continuity between the harness connectors.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair the main line between the harness connectors B7 and B3.

4.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
