Diagnosis ProcedureINFOID:0000000009464626
Regarding Wiring Diagram information, refer to WW-23, "Wiring Diagram - With Rear View Camera Washer
Control System".
1. CHECK WIPER RELAY OPERATION
IPDM E/R AUTO ACTIVE TEST
1. Start IPDM E/R auto active test. Refer to PCS-8, "Diagnosis Description"
.
2. Check that the front wiper operates at the LO/HI operation.
CONSULT ACTIVE TEST
1. Select FRONT WIPER of IPDM E/R active test item.
2. While operating the test item, check that front wiper LO/HI operation and OFF.
is the inspection result normal?
YES >> GO TO 5.
NO >> GO TO 2.
2. CHECK FRONT WIPER MOTOR FUSE

Is the fuse blown?
YES >> Replace the fuse after repairing the affected circuit.
NO >> GO TO 3.
3. CHECK FRONT WIPER MOTOR (GND) OPEN CIRCUIT
1. Disconnect front wiper motor.
2. Check continuity between front wiper motor harness connector E25 and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace the harness or connectors.
4. CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE
CONSULT ACTIVE TEST
1. Turn the ignition switch ON.
2. Select FRONT WIPER of IPDM E/R active test item.
3. With operating the test item, check volt age between IPDM E/R harness connector E18 and ground.
Lo : Front wiper LO operation
Hi : Front wiper HI operation
Off : Stop the front wiper.
