1.CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE CONSULT-III ACTIVE TEST

1. Turn the ignition switch OFF.
2. Disconnect front wiper motor connector.
3. Turn the ignition switch ON.
4. Select “FRONT WIPER” of IPDM E/R active test item.
5. With operating the test item, check voltage between IPDM E/R harness connector and ground.

Terminals | Test item | Voltage (Approx.)
(+) | (−)
IPDM E/R | Ground | FRONT WIPER
Connector | Terminal
E5 | 4 | Lo | Battery voltage
Off | 0 V

Is the measurement value normal?
YES>>GO TO 2.
NO>>Replace IPDM E/R.
2.CHECK FRONT WIPER MOTOR (LO) OPEN CIRCUIT

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 | 4 | E42 | 1 | Existed

Does continuity exist?
YES>>GO TO 3.
NO>>Repair the harness or connector.
3.CHECK FRONT WIPER MOTOR (LO) SHORT CIRCUIT
Check continuity between IPDM E/R harness connector and ground.

IPDM E/R | Ground | Continuity
Connector | Terminal
E5 | 4 | Not existed

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