CAN

MAIN LINE BETWEEN A-BAG AND ABS 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). the following harness connectors.
- Harness connector M1
- Harness connector E30
Is the inspection result normal?
YES - GO TO 2.
NO - Repair the terminal and connector.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of combination meter.
2. Check the continuity between the combination meter harness connector and the harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair the main line between the combination meter and the harness connector M1.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of ABS actuator and electric unit (control unit).
2. Check the continuity between the harness connector and the ABS actuator and electric unit (control unit) harness connector.
- Models with ABS





- Models with VDC





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 air bag diagnosis sensor unit and the
ABS actuator and electric unit (control unit).
NO - Repair the main line between the harness connector E30 and the ABS actuator and electric unit
(control unit).
