FRONT WIPER DOES NOT OPERATE

Description

INFOID:0000000004216523

The front wiper does not operate under any operation conditions

Diagnosis Procedure

INFOID:0000000004216524

1.

 CHECK WIPER RELAY OPERATION

IPDM E/R AUTO ACTIVE TEST

1. Start IPDM E/R auto active test. Refer to 

PCS-14, "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. While operating the test item, check that front wiper LO/HI operation and OFF.

Does the front wiper operate?

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 fuse 30A (No. 55, located in the IPDM E/R) is not blown.
Is the fuse blown?

YES

>> Replace the fuse after repairing the affected circuit.

NO

>> GO TO 3

3.

 CHECK FRONT WIPER MOTOR (GND) OPEN CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect front wiper motor.

3. Check continuity between front wiper motor harness connector

and ground.

Does continuity exist?

YES

>> GO TO 4

NO

>> Repair or replace harness.

4.

 CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1. Turn the ignition switch OFF.

2. Turn the ignition switch ON.

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

4. While operating the test item, check voltage between IPDM E/R

harness connector and ground.

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

Is the status of item normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-39, "Removal and Installation"

.

NO

>> GO TO 6

6.

 CHECK COMBINATION SWITCH

1. Perform the inspection of the combination switch. Refer to 

BCS-10, "System Description"

.

Is combination switch normal?

YES

>> Replace BCM. Refer to 

BCS-87, "Removal and Installation"

.

NO

>> Repair or replace the malfunctioning parts.

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.
