4. Check voltage between front wiper motor harness connector and ground.





Is the measurement value normal?
YES - Replace front wiper motor.
NO - GO TO 2.
2.CHECK FRONT WIPER MOTOR (AUTO STOP) OPEN 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 - GO TO 3.
NO - Repair the harnesses or connectors.
3.CHECK FRONT WIPER MOTOR (AUTO STOP) SHORT CIRCUIT
