NORMAL OPERATING CONDITION
DescriptionINFOID:0000000006300483
FRONT WIPER MOTOR PROTECTION FUNCTION
IPDM E/R may stop the front wiper to protect the front wiper motor if any obstruction (operation resistance)
such as a large amount of snow is detected during the front wiper operation.
At that time turn OFF the front wiper and remove t he foreign object. Then wait for approximately 20 seconds
or more and reactivate the front wiper. The wiper will operate normally.
REAR WIPER MOTOR PROTECTION FUNCTION
BCM may stop rear wiper to protect the rear wiper motor when the rear wiper is stopped for 5 seconds or
more due to a snowfall.
Rear wiper operates normally one minute after t he obstacles are removed with rear wiper OFF.

The front wiper does not operate under any operation conditions.
Diagnosis ProcedureINFOID:0000000006300485
1.CHECK WIPER RELAY OPERATION
CONSULT-III ACTIVE TEST
1. Select “FRONT WIPER” of IPDM E/R active test item.
2. With operating the test item, check front wiper operation.
Is front wiper operation normally?
YES >> GO TO 5.
NO >> GO TO 2.
2.CHECK FRONT WIPER MOTOR FUSE
Check front wiper motor fuse. Refer to WW-35, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace the fuse after repairing the applicable circuit.
3.CHECK FRONT WIPER MOTOR GROUND CIRCUIT
Check front wiper motor ground circuit. Refer to WW-39, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace harness.
4.CHECK FRONT WIPER MOTOR INPUT VOLTAGE
CONSULT-III ACTIVE TEST
1. Turn ignition switch OFF.
2. Disconnect front wiper motor connector.
3. Turn ignition switch ON.
4. Select “FRONT WIPER” of IPDM E/R active test item.
5. With operating the test item, check voltage between front wiper motor harness connector and ground.
Is the inspection result normal?
YES >> Replace front wiper motor.
NO >> Replace IPDM E/R.
5.CHECK FRONT WIPER REQUEST SIGNAL INPUT
CONSULT-III DATA MONITOR
1. Select “FR WIP REQ” of IPDM E/R data monitor item.
2. Switch the front wiper switch to HI and LO. Lo : Front wiper LO operation
Hi : Front wiper HI operation
Off : Stop the front wiper.
