FRONT WIPER AND WASHER SYSTEM

WW-11

< FUNCTION DIAGNOSIS >

• When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper

motor returns to the stop position.

NOTE:
• BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF.
• IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF.

FRONT WIPER OPERATION LINKED WITH WASHER

• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the

washer linked operating condition of the front wiper.

• BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 2 times

when the front washer switch OFF is detected.

Washer linked operating condition of front wiper

- Ignition switch ON
- Front washer switch ON (0.4 second or more)
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
• The washer pump is grounded through the combination switch with the front washer switch ON.

FRONT WIPER FAIL-SAFE OPERATION

IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to

< FUNCTION DIAGNOSIS >

• BCM reads a rear wiper stop position 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 3
times.

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 warning lamp
• Front wiper (LO, HI)
• Parking lamps
• License plate lamps
• Side maker lamps
• Tail lamps
• Front fog lamps
• Headlamps (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan

Operation Procedure

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.

Turn the ignition switch OFF.

Turn the ignition switch ON, and within 20 seconds, press the front door switch (driver side) 10 times.
Then turn the ignition switch OFF.

CAUTION:

Close passenger door.

Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test
starts.

The oil pressure warning lamp starts blinking when the auto active test starts.

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 the ignition switch OFF.

CAUTION:

• If auto active test mode cannot be actuated, check door switch system. Refer to

DLK-411,

"Component Function Check"

• Do not start the engine.

DIAGNOSIS SYSTEM (IPDM E/R)

WW-21

< FUNCTION DIAGNOSIS >

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.
