FRONT WIPER MOTOR HI CIRCUIT

Component Function Check

INFOID:0000000010048952

1.

 CHECK FRONT WIPER HI 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 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 HI operation and OFF.

Does the front wiper operate?

YES

>> The front wiper motor HI circuit is normal.

NO

>> Refer to 

WW-20, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010048953

Regarding Wiring Diagram information, refer to 

WW-63, "Wiring Diagram"

.

1.

 CHECK FRONT WIPER MOTOR (HI) OUTPUT VOLTAGE

CONSULT ACTIVE TEST

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

>> GO TO 2

NO

>> Replace IPDM E/R. Refer to 

PCS-35, "Removal and Installation"

.

2.

 CHECK FRONT WIPER MOTOR (HI) OPEN CIRCUIT
