CAN

MAIN LINE BETWEEN IPDM-E AND DLC CIRCUIT

Diagnosis Procedure


1. CHECK CONNECTOR

1.Turn the ignition switch OFF.
2.Disconnect the battery cable from the negative terminal.
3.Check the following terminals and connectors for damage, bend and loose connection (connector side and harness side).
-Harness connector E105
-Harness connector M77
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.
-IPDM E/R
-Harness connectors E105 and M77
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 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.
