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.

Terminals | Voltage (Approx.)
(+) | (−)
IPDM E/R | Ground
Connector | Terminal
E5 | 16 | Battery voltage

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.

IPDM E/R | Ground | Continuity
Connector | Terminal
E5 | 16 | Not existed

Does continuity exist?
YES>>Repair the harness or connector.
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.

IPDM E/R | Front wiper motor | Continuity
Connector | Terminal | Connector | Terminal
E5 | 16 | E42 | 5 | Existed

Does continuity exist?
YES>>Replace front wiper motor.
NO>>Repair the harness or connector.
