GENERAL INFORMATION

REAR WIPER AND WASHER

REAR WIPER OPERATION

REAR WASHER OPERATION

DESCRIPTION OF CONSTRUCTION AND OPERATION

Rear wiper control [Initial condition: 8 seconds (without successive operations) ]

Mitsubishi Outlander. Exterior

1. When the rear wiper switch on the column switch is turned ON while the ignition switch is in ACC or ON position, ETACS turns the rear wiper relay ON for 3 seconds (for approximately 2 cycles) and operates the intermittent action in 8 seconds interval.

When the selector lever is moved to R (reverse) position during the rear wiper operation, the transmission range switch R (reverse) turns ON, and one second after that, ETACS turns the rear wiper relay ON for 3 seconds (for approximately 2 cycles), and operates the intermittent action in 8 seconds interval again.

2. By the special operation of the rear wiper switch on the column switch (2 consecutive operations), the rear wiper can operate continuously regardless on the set intermittent time.

NOTE: Using the customization function, the rear wiper intermittent time can be adjusted.

Rear wiper linked with washer function Initial condition: with function

Mitsubishi Outlander. Exterior

When the rear washer switch on the column switch is turned ON while the ignition switch is in ACC or ON position, ETACS turns the rear washer relay ON.

The rear washer relay turns ON after the rear washer switch has been ON for 0.3 seconds, then turns the rear wiper relay ON to operate the rear wiper simultaneously.

When the rear washer switch is turned OFF, after 3 seconds the rear wiper is turned OFF.

If the rear washer switch is turned ON during the rear wiper operation, 7.4 seconds after turning OFF the rear wiper relay turns OFF, the intermittent action is resumed in 8 seconds interval.

NOTE: Using the customization function, the washer linked rear wiper function can be invalidated.

"R" Position During Wiper Operation Circuit

Mitsubishi Outlander. Exterior

CIRCUIT OPERATION

The ETACS-ECU operates the rear wiper consecutively when the selector lever is moved to "R" position while the rear wiper is turned on.

TECHNICAL DESCRIPTION (COMMENT)

If the rear wiper does not work consecutively, the transmission range switch ("R" position) or the ETACS-ECU may be defective.

TROUBLESHOOTING HINTS

DIAGNOSIS

Required Special Tools:

STEP 1. Verify the rear wiper.

Check that the rear wiper system works normally by operating the rear wiper switch.

Q: Does the rear wiper operate?

YES : Go to Step 2.

NO <Rear wiper does not work.> : Refer to Inspection Procedure 1 "Rear wiper does not work at all P.51"

STEP 2. Use the scan tool MB991958 to diagnose the CAN bus lines.

Connect the scan tool. Q: Is the check result normal?

YES : Go to Step 3.

NO : Repair the CAN bus line.

Mitsubishi Outlander. Exterior

STEP 3. Use the scan tool MB991958 to diagnose other system diagnostic trouble code

Connect the scan tool. Check that the TCM sets a bus-off diagnostic trouble code.

Q: Is the diagnostic trouble code set?

YES : A poor connection, open circuit or other intermittent malfunction is present in the CAN bus lines between the TCM and the ETACS-ECU.

NO : Go to Step 4.

STEP 4. Retest the system.

Check that the rear wiper operates continuously when the selector lever is moved to the R position during the rear wiper operation.

Q: Is the check result normal?

YES : Intermittent malfunction. NO : Replace the ETACS-ECU.

INSPECTION PROCEDURE 4: Rear washer does not work normally.

CIRCUIT OPERATION

The rear washer switch sends a signal through the column-ECU (incorporated in the column switch) to the ETACS-ECU. If the column-ECU sends a rear washer switch "ON" signal to the ETACS-ECU, the ETACS-ECU turns on the relay (incorporated in the ETACS-ECU), thus causing the windshield and rear washer motor to be turned on.

TECHNICAL DESCRIPTION (COMMENT)

If the rear washer does not work normally, the windshield and rear washer motor, the column switch (windshield wiper and washer switch) or the ETACS-ECU may be defective.
