STEP 2. Check the rear wiper motor.
(1) Disconnect rear wiper motor connector F-04.
(2) Connect the vehicle battery to the rear wiper motor

connector as shown, and operate the rear wiper. While the
rear wiper is working, disconnect the battery at positions
other than the specified park position to stop the rear wiper
motor.

(3) When the battery is connected as shown, the motor should

run and then stop at the specified park position.

Q: Does the rear wiper motor operate normally?

YES : Go to Step 3.
NO : Replace the rear wiper motor. The rear wiper should

now stop at the specified park position.

STEP 3. Check rear wiper motor connector F-04 and
ETACS-ECU connector C-311 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Is rear wiper motor connector F-04 and ETACS-ECU

connector C-311 in good condition?
YES : Go to Step 4.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 4. Check the wiring harness between rear wiper
motor connector F-04 (terminals 2,4) and ETACS-ECU
connector C-311 (terminals 8, 4).
NOTE: Also check intermediate connector D-12 for loose, cor-
roded or damaged terminals, or terminals pushed back in the
connector.
Q: Is the wiring harness between rear wiper motor

connector F-04 (terminals 2,4) and ETACS-ECU
connector C-311 (terminals 8, 4) in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Cables and wire check

STEP 5. Check the input signal related to the rear wiper
operation.

• Ignition switch: ACC or ON

• Rear wiper: In operation

NOTE: Confirm that the scan tool displays ON to OFF when
rear wiper stops at the specified park position.

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : Intermittent malfunction. Refer to GROUP 00, How to

cope with intermittent malfunction

P.00-15

.

NO : Replace the ETACS-ECU.

INSPECTION PROCEDURE 3: When the selector lever is moved to "R" position during the rear wiper
operation, the rear wiper does not operate at the continuous mode.

.

CIRCUIT OPERATION

The ETACS-ECU operates the rear wiper consecu-
tively when the selector lever is moved to "R" posi-
tion 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

• The back-up light switch may be defective

• The ETACS-ECU may be defective

• The wiring harness may be damaged or the con-

nectors may have loose, corroded or damaged
terminals, pushed back in the connector

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

."

STEP 2. Use the scan tool MB991958 to diagnose the CAN
bus lines.
Connect the scan tool. Refer to GROUP 54A ETACS, "Diag-
nostic function

P.54A-729

."

Q: Is the check result normal?

YES : Go to Step 3.
NO : Repair the CAN bus line (Refer to GROUP 54C

STEP 3. Use the scan tool MB991958 to diagnose other
system diagnostic trouble code
Connect the scan tool. Refer to GROUP 54A ETACS, "Diag-
nostic function

P.54A-729

."

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 (Refer to GROUP 00,
