1.

CHECK FRONT WIPER LO 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 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 (LO) operation normally?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to 

WW-25, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000000924448

1.

CHECK FRONT WIPER MOTOR FUSE

1.

Turn the ignition switch OFF.

2.

Check that the following fuses are not fusing.

Is the fuse fusing?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK FRONT WIPER MOTOR (LO) SHORT CIRCUIT

1.

Disconnect front wiper motor connector.

2.

Disconnect IPDM E/R connector.

3.

Check continuity between IPDM E/R harness connector and ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors. And then replace the fuse.

NO

>> Replace the fuse. (Replace IPDM E/R if the fuse is fusing again.)

3.

CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1.

Connect IPDM E/R 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.
