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.

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

• 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.
• 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, BC M 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)
• Front and rear washer motor becomes grounded through t he combination switch (wiper and washer switch)
when the rear washer switch is turned ON.
REAR WIPER DROP WIPE OPERATION
• BCM controls the rear wiper to operate once acco rding 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 onc e time approximately three seconds later after the washer
interlocking operation of the rear wiper.

AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation:
• Front wiper (LO, HI)
• Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions:
• Passenger door is open
• CONSULT is connected
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
• When auto active test has to be cancelled halfw ay through test, turn the ignition switch OFF.
• When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
