>> The front wiper motor HI circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000004202200
1.
CHECK FRONT WIPER MOTOR (HI) OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
1. Turn the ignition switch OFF.
2. Disconnect front wiper motor.
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.
Is the measurement normal?
YES
>> GO TO 2
NO
>> Replace IPDM E/R. Refer to
PCS-48, "Removal and Installation"
2.
CHECK FRONT WIPER MOTOR (HI) OPEN CIRCUIT
