NORMAL OPERATING CONDITION

Description

INFOID:0000000009649566

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 the 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 the obstacles are removed with rear wiper OFF.

FRONT WIPER DOES NOT OPERATE

FRONT WIPER DOES NOT OPERATE

Description

INFOID:0000000009649567

The front wiper does not operate under any operation conditions.

Diagnosis Procedure

INFOID:0000000009649568

1.

CHECK WIPER RELAY OPERATION

CONSULT 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 4.

NO

>> GO TO 2.

2.

CHECK FUSES

Check that the following fuse is not fusing.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace the fuse with a new one after repairing the applicable circuit.

3.

CHECK FRONT WIPER MOTOR GROUND CIRCUIT

Check front wiper motor ground circuit. Refer to

WW-40, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace harness.

4.

CHECK FRONT WIPER REQUEST SIGNAL INPUT

CONSULT 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 status of “FR WIP REQ”.

Is the inspection result normal?

YES

>> Replace IPDM E/R.

NO

>> GO TO 5.

5.

CHECK COMBINATION SWITCH

Perform the inspection of the combination switch. Refer to

BCS-96, "Symptom Table"

.

Is combination switch normal?

YES

>> Replace BCM. Refer to

BCS-98, "Removal and Installation"

.

Lo

: Front wiper LO operation

Hi

: Front wiper HI operation

Off

: Stop the front wiper.
