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.

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.

2.

Check continuity between front wiper motor harness connector and ground.

Does continuity exist?

YES

>> GO TO 4.

NO

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.

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.
