FRONT WIPER MOTOR HI CIRCUIT

Component Function Check

INFOID:0000000009541150

1.

CHECK FRONT WIPER HI 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 on HI operation.

CONSULT ACTIVE TEST

1. Select FR WIPER of BCM (WIPER) active test item.

2. Check front wiper operation.

Is the inspection result normal?

YES

>> Front wiper motor HI circuit is normal.

NO

>> Refer to 

WW-35, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009541151

Regarding Wiring Diagram information, refer to 

WW-21, "Wiring Diagram"

.

1.

 CHECK FRONT WIPER MOTOR FUSE

1. Turn the ignition switch OFF.

2. Check that the following fuse is not blown.

Is the fuse blown?

YES

>> Replace the fuse after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK FRONT WIPER MOTOR (HI) OUTPUT VOLTAGE

1. Turn the ignition switch ON.

2. Select FR WIPER of BCM (WIPER) active test item.

3. While performing the active test, check voltage between IPDM E/R harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Replace IPDM E/R. Refer to 

PCS-30, "Removal and Installation"

.

3.

 CHECK FRONT WIPER MOTOR (HI) OPEN CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect IPDM E/R and front wiper motor.

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

FRONT WIPER AUTO STOP SIGNAL CIRCUIT

Component Function Check

INFOID:0000000009541152

1.

 CHECK FRONT WIPER (AUTO STOP) SIGNAL

1. Select FR WIPER STOP of BCM (WIPER) data monitor item.

2. Operate the front wiper.

3. Check that FR WIPER STOP changes from ON to OFF according to the wiper position.

Is the inspection result normal?

YES

>> Front wiper auto stop signal circuit is normal.

NO

>> Refer to 

WW-37, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009541153

Regarding Wiring Diagram information, refer to 

WW-21, "Wiring Diagram"

.

1.

 CHECK FRONT WIPER MOTOR (AUTO STOP) OUTPUT VOLTAGE

1. Turn the ignition switch ON.

2. Check voltage between IPDM E/R harness connector and ground.

Is the inspection result normal?

YES

>> Check for intermittent failure.

NO

>> GO TO 2

2.

 CHECK FRONT WIPER MOTOR (AUTO STOP) SHORT CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect IPDM E/R and front wiper motor.

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

Is the inspection result normal?

YES

>> Repair or replace harness.

NO

>> GO TO 3.

3.

 CHECK FRONT WIPER MOTOR (AUTO STOP) CIRCUIT CONTINUITY

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