CAN

MAIN LINE BETWEEN TCM 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).
- Harness connector M6
- Harness connector E106
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.
- Harness connectors F103 and M116
- Harness connectors M6 and E106
2. Check the continuity between the harness connectors.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair the main line between the harness connectors M116 and M6.
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.





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 TCM and the ABS actuator and electric unit (control unit).
NO - Repair the main line between the harness connector E106 and the ABS actuator and electric unit
(control unit).
