FRONT WIPER MOTOR LO CIRCUIT

Component Function Check

INFOID:0000000009756087

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"

 (with Intelligent Key system) or

PCS-37, "Diagnosis Description"

 (without Intelligent Key system).

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

CONSULT ACTIVE TEST

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

2. While operating the test item, check that front wiper LO operation and OFF.

Is the inspection result normal?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to 

WW-37, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009756088

Regarding Wiring Diagram information, refer to 

WW-24, "Wiring Diagram - With Intelligent Key"

 or

"Wiring Diagram - Without Intelligent Key"

.

1.

 CHECK FRONT WIPER MOTOR (LO) INPUT 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 E45 and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace IPDM E/R. Refer to 

PCS-30, "Removal and Installation"

 (with Intelligent Key system) or

PCS-58, "Removal and Installation"

 (without Intelligent Key system).

2.

 CHECK FRONT WIPER MOTOR (LO) OPEN CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect IPDM E/R.

3. Check continuity between IPDM E/R harness connector E45 and front wiper motor harness connector E1.

Is the inspection result normal?

Lo

: Front wiper LO operation

Off

: Stop the front wiper.
