STEP 19. Check the wiring harness between power 
window main switch connector H-05 (terminals 10) and 
ETACS-ECU connector D-223 (terminals 54).
Q: Is the wiring harness between power window main 

switch connector H-05 (terminals 10) and ETACS-ECU 
connector D-223 (terminals 54) in good condition?
YES : Replace the ETACS-ECU. If the central door locking 

system works normally, input signal from the door lock 
switch should be normal.

NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. If the central 
door locking system works normally, input signal from 
the door lock switch should be normal.

INSPECTION PROCEDURE P-8: ETACS-ECU does not receive an auto-stop signal from the rear wiper 
motor.

.

CIRCUIT OPERATION
The ETACS-ECU makes the rear wiper stop at the 
predetermined park position according to the auto-
stop signal from the rear wiper motor.

.

TECHNICAL DESCRIPTION (COMMENT)
If this signal is not normal, the rear wiper does not 
stop at the predetermined park position.

.

TROUBLESHOOTING HINTS

• The rear wiper motor may be defective

• The ETACS-ECU may be defective

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB991502: Scan Tool (MUT-II)

STEP 1. Check the rear wiper.
Q: Does the rear wiper motor operate (however, the rear 

wiper does not stop at the predetermined park 
position)?
YES : Go to Step 2.
NO :  Refer to Inspection Procedure H-1 "Rear wiper dose 

not work at all 

P.54Bb-268

STEP 2. Check the rear wiper motor.
(1) Disconnect rear wiper motor connector I-07.
(2) While the rear wiper motor is running, disconnect the 

battery to stop the motor.

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

run again and stop at the predetermined park position.

Q: Does the rear wiper motor operate normally?

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

operates normally, it indicates that a correct auto-stop 
signal is sent from the rear wiper motor.

STEP 3. Check the ignition switch (ACC) line of the power 
supply circuit to the rear wiper motor. Test at rear wiper 
motor connector I-07.
(1) Disconnect rear wiper motor connector I-07 and measure 

the voltage available at the wiring harness side of the 
connector.

(2) Turn the ignition switch to the "ACC" position.

(3) Measure the voltage between terminal 4 and ground.

• The voltage should equal approximately 12 volts (bat-

tery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 6.
NO :  Go to Step 4.

STEP 4. Check rear wiper motor connector I-07 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is rear wiper motor connector I-07 in good condition?

YES : Go to Step 5.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the rear wiper operates normally, it 

indicates that a correct auto-stop signal is sent from 
the rear wiper motor.
