NORMAL OPERATING CONDITION

Description

INFOID:0000000000924458

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

Description

INFOID:0000000000924456

The front wiper does not operate under any operation conditions.

Diagnosis Procedure

INFOID:0000000000924457

1.

CHECK WIPER RELAY OPERATION

IPDM E/R AUTO ACTIVE TEST

1.

Start IPDM E/R auto active test. Refer to 

PCS-9, "Diagnosis Description"

.

2.

Check that the front wiper operates at the LO/HI 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

1.

Turn the ignition switch OFF.

2.

Check that the front wiper motor 30A fuse (#44) is not fusing.

Is the fuse fusing?

YES

>> Replace the fuse after repairing the applicable circuit.

NO

>> GO TO 3.

3.

CHECK FRONT WIPER MOTOR GROUND OPEN CIRCUIT 

1.

Disconnect front wiper motor connector.

2.

Check continuity between front wiper motor harness connector and ground.

Does continuity exist?

YES

>> GO TO 4.

NO

>> Repair the harnesses or connectors.

4.

CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1.

Disconnect front wiper motor connector.

2.

Turn the ignition switch ON.

3.

Select "FRONT WIPER" of IPDM E/R active test item.

4.

With operating the test item, check voltage between IPDM E/R harness connector and ground.

LO

: Front wiper LO operation

HI

: Front wiper HI operation

< SYMPTOM DIAGNOSIS >

FRONT WIPER DOES NOT OPERATE

Is the measurement value 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 status of "FR WIP REQ".

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 

BCS-63, "Symptom Table"

.

Is combination switch normal?

YES

>> Replace BCM. Refer to 

BCS-64, "Exploded View"

.

NO

>> Repair or replace the applicable parts.
