DTC/CIRCUIT DIAGNOSIS

FRONT WIPER MOTOR LO CIRCUIT

Component Function Check

INFOID:0000000010430974

1.

CHECK FRONT WIPER LO 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 the inspection result normal?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to 

WW-47, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010430975

1.

CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE

1.

Turn ignition switch OFF.

2.

Disconnect front wiper motor connector.

3.

Turn ignition switch ON.

4.

Turn front wiper switch to LOW, and wait for 10 seconds.

5.

Check voltage between front wiper motor harness connector and ground.

LHD

RHD

*: According to front wiper protection function, IPDM E/R supplies voltage for 10 seconds (9 

−

 16 V) and then

stops for 20 seconds (0 

−

 1 V). This operation occurs repeatedly.

Is the inspection result normal?

YES

>> Replace front wiper motor.

NO

>> GO TO 2.

2.

CHECK FRONT WIPER MOTOR (LO) CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Check continuity between IPDM E/R harness connector and front wiper motor harness connector.
