FRONT WIPER DOES NOT OPERATE

Description

INFOID:0000000010048971

The front wiper does not operate under any operation conditions

Diagnosis Procedure

INFOID:0000000010048972

Regarding Wiring Diagram information, refer to 

WW-63, "Wiring Diagram"

.

1.

 CHECK WIPER RELAY OPERATION

IPDM E/R AUTO ACTIVE TEST

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

PCS-11, "Diagnosis Description"

.

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

CONSULT ACTIVE TEST

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

2. While operating the test item, check 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 ACTIVE TEST

LO

: Front wiper LO operation

HI

: Front wiper HI operation

OFF

: Stop the front wiper.

1. Turn the ignition switch OFF.

2. Disconnect front wiper motor.

3. Turn the ignition switch ON.

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

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

harness connector and ground.

Is the measurement normal?

YES LO circuit>>Refer to 

WW-18, "Diagnosis Procedure"

.

YES HI circuit>>Refer to 

WW-20, "Diagnosis Procedure"

.

NO

>> Replace IPDM E/R. Refer to 

PCS-35, "Removal and Installation"

.

5.

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

Is the status of item normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-35, "Removal and Installation"

.

NO

>> GO TO 6

6.

 CHECK COMBINATION SWITCH (WIPER AND WASHER SWITCH)

Perform the inspection of the combination switch (wiper and washer switch). Refer to 

BCS-10, "System

Description"

.

Is combination switch (wiper and washer switch) normal?

YES

>> Replace BCM. Refer to 

BCS-79, "Removal and Installation"

.

NO

>> Repair or replace the malfunctioning parts.
