Start IPDM E/R auto active test. Refer to 

PCS-10, "Diagnosis Description"

.

2.

Check that the front wiper operates at the LO/HI operation.

CONSULT-III ACTIVE TEST

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.

< SYMPTOM DIAGNOSIS >

FRONT WIPER DOES NOT OPERATE

Is the measurement 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.

3.

With operating the front wiper switch, check the monitor status.

Is the status of item normal?

YES

>> Replace IPDM E/R.

NO

>> GO TO 6.

6.

CHECK COMBINATION SWITCH

1.

Perform the inspection of the combination switch. Refer to
