Diagnosis Procedure

INFOID:0000000006164532

Regarding Wiring Diagram information, refer to 

WW-42, "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 measurement value normal?

YES

>> GO TO 3

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.

Does continuity exist?

YES

>> Repair or replace harness.

NO

>> Replace IPDM E/R. Refer to 

PCS-28, "Removal and Installation of IPDM E/R"
