Diagnosis ProcedureINFOID:0000000005928541
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 M69
- Harness connector E7
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair the terminal and connector.
2.CHECK HARNESS CONTI NUITY (OPEN CIRCUIT)
1. Disconnect the harness connectors M69 and E7.
2. Check the continuity between the data link connector and the harness connector.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair the main line between the data link connector and the harness connector M69.
3.CHECK HARNESS CONTI NUITY (OPEN CIRCUIT)
1. Disconnect the connector of ABS actuat or 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 data link connector and the ABS actuator and electric unit (control unit).
NO >> Repair the main line between the harness connec tor E7 and the ABS actuator and electric unit
(control unit).
