REAR WIPER AND WASHER SYSTEM
System DiagramINFOID:0000000001366596
System DescriptionINFOID:0000000001366597
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 condition 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 according to the rear wiper ON operating condition.
Rear wiper ON operating condition
- Ignition switch ON
- Rear wiper switch ON
REAR WIPER INT OPERATION LINKED WITH VEHICLE SPEED
 BCM supplies power to the rear wiper motor according to the INT operating condition.
Rear wiper INT operating condition- Ignition switch ON
- Rear wiper switch INT
 BCM controls the rear wiper to operate once.
 BCM detects the rear wiper motor stopping position.
 BCM supplies power to the rear wiper motor after an intermittent from the stop of the rear wiper motor.
REAR WIPER AUTO STOP OPERATION
 BCM stops supplying power to the rear wiper motor when the rear wiper switch is turned OFF.

< FUNCTION DIAGNOSIS >
REAR WIPER AND WASHER SYSTEM
 BCM reads an auto stop signal from the rear wiper motor to detect a rear wiper motor position.
 When the rear wiper motor is at other than the stopping position, BCM continues to supply power to the rear
wiper motor until it returns to the stopping position.
NOTE:
BCM stops supplying power to the rear wiper motor when the ignition switch is turned OFF.
REAR WIPER OPERATION LINKED WITH WASHER
 BCM supplies power to the rear wiper motor according to the washer linked operating condition of rear
wiper. When the rear washer switch is turned OFF, BCM controls rear wiper to operate approximately three
times.
Washer linked operating condition of rear wiper- Ignition switch ON
- Rear washer switch ON (0.4 second or more)
 Washer pump becomes grounded through the combination switch when the rear washer switch is turned
ON.
REAR WIPER DROP WIPE OPERATION
 BCM controls the rear wiper to operate once according to the rear wiper drop wipe operating condition.
Rear wiper drop wipe operating condition
- Ignition switch ON
- Rear wiper switch OFF
- Rear washer switch OFF
 BCM controls the rear wiper so that it operates once time approximately three seconds later after the washer
interlocking operation of the rear wiper.

WASHER SWITCH
DescriptionINFOID:0000000001366617
 Washer switch is integrated with combination switch.
 Combination switch switches polarity between front washer operating and rear washer operating to supply
power to the front and rear washer motor on ground.
Component InspectionINFOID:0000000001366618
1. CHECK FRONT WASHER SWITCH
1. Turn the ignition switch OFF.
2. Disconnect combination switch.
3. Check continuity between the combination switch terminals.
Does continuity exist?
YES >> Wiper and washer switch is normal.
NO >> Replace combination switch. Refer to EXL-101, "
Removal and Installation".
2. CHECK REAR WASHER SWITCH
1. Turn the ignition switch OFF.
2. Disconnect combination switch.
3. Check continuity between the combination switch terminals.
