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
• 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.

• 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)
• Front and rear washer motor 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.

Diagnosis Description
INFOID:0000000005484555
AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
• Oil pressure low warning indicator
• Oil pressure gauge
• Rear window defogger
• Front wipers
• Tail, license and parking lamps
• Front fog lamps (if equipped)
• Headlamps (Hi, Lo)
• A/C compressor (magnetic clutch)
• Cooling fan
Operation Procedure
1. Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield dam-
age due to wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
2. Turn ignition switch OFF.
3. Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. After 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 mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system. Refer to
(with Intelligent Key system),
(without Intelligent Key system).
• Do not start the engine.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 7 steps are repeated 3 times.

DIAGNOSIS SYSTEM (IPDM E/R)
Concept of auto active test
• IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
