SYSTEM
2. Front washer switch ON.
3. The front washer switch provides ground for the front and rear washer motor.
4. BCM reads the combination switch position and transmi ts the front wiper request signal (LO) to IPDM E/R
using CAN communication.
5. BCM transmits the front wiper request signal (LO) to IPDM E/R using CAN communication.
6. IPDM E/R turns ON the front wiper relay.
7. The front wiper operates.
NOTE:
BCM transmits the front wiper request signal (LO) so t hat the front wiper operates approximately 3 times after
front washer switch OFF is detected.
FRONT WIPER AND WASHER SYSTEM : Fail-SafeINFOID:0000000012433200
FA I L −SAFE OPERATION
IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to
PCS-19, "
Fail-safe".

OUTLINE
The rear wiper is controlled by each function of BCM.
Control by BCM
• Combination switch reading function
• Rear wiper control function
REAR WIPER BASIC OPERATION
• BCM detects the combination switch conditi on by the combination switch reading function.
• BCM controls the rear wiper to start or stop.
REAR WIPER ON OPERATION
• BCM supplies power to the rear wiper motor ac cording to the rear wiper ON operating condition.
Rear wiper ON operating condition- Ignition switch ON
- Rear wiper switch ON
REAR WIPER INT OPERATION
• BCM supplies power to the rear wiper motor according to the INT operating condition.

FRONT WIPER DO ES NOT OPERATE
DescriptionINFOID:0000000012433230
The front wiper does not operate under any operation conditions.
Diagnosis ProcedureINFOID:0000000012433231
Regarding Wiring Diagram information, refer to WW-22, "Wiring Diagram".
1. CHECK WIPER RELAY 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 LO and 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 >> GO TO 5.
NO >> GO TO 2.
2. CHECK FRONT WIPER MOTOR FUSE
Refer to WW-35, "
Diagnosis Procedure".
Is the fuse blown?
YES >> Replace the fuse after repairing the affected circuit.
NO >> GO TO 3.
3. CHECK FRONT WIPER MOTOR GROUND CIRCUIT
Refer to WW-42, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace harness.
4. CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE
1. Turn the ignition switch ON.
2. With CONSULT, select FRONT WIPER of IPDM E/R ACTIVE TEST item.
3. Check voltage between IPDM E/R harness connector and ground while wipers are operating.
Is the inspection result normal?
YES >> Replace front wiper motor. Refer to WW-66, "Removal and Installation".
NO >> Replace IPDM E/R. Refer to PCS-30, "
Removal and Installation".
5. CHECK FRONT WIPER REQUEST SIGNAL INPUTLO : Front wiper LO operation
HI : Front wiper HI operation
OFF : Front wiper stop
