Diagnosis Procedure

FRONT WIPER AUTO STOP SIGNAL CIRCUIT


Diagnosis Procedure

1.CHECK FRONT WIPER MOTOR (AUTO STOP) OUTPUT VOLTAGE
1. Turn the ignition switch OFF.
2. Disconnect front wiper motor connector.
3. Turn the ignition switch ON.
4. Check voltage between IPDM E/R harness connector and ground.





Is the measurement value normal?
YES - GO TO 3.
NO - GO TO 2.
2.CHECK FRONT WIPER MOTOR (AUTO STOP) SHORT CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between IPDM E/R harness connector and ground.





Does continuity exist?
YES - Repair the harnesses or connectors.
NO - Replace IPDM E/R.
3.CHECK FRONT WIPER MOTOR (AUTO STOP) CIRCUIT CONTINUITY
1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between IPDM E/R harness connector and front wiper motor harness connector.





Does continuity exist?
YES - Replace front wiper motor.
NO - Repair the harnesses or connectors.
