3. Check the following terminals and connectors for damage, bend and loose connection (connector side and harness side).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair the terminal and connector.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the following harness connectors.
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.
