STEP 14. Check ETACS-ECU connector D-223 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector D-223 in good condition?

YES : Go to Step 15.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the central door locking system works 

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

STEP 15. Check the wiring harness between power 
window main switch H-05 (terminal 3) and ground.
Q: Is the wiring harness between power window main 

switch connector H-05 (terminal 3) and ground in good 
condition?
YES : Replace the ETACS-ECU.
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.

STEP 16. Check ETACS-ECU connector D-223 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector D-223 in good condition?

YES : Go to Step 17.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the central door locking system works 

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

STEP 17. Check the wiring harness between power 
window main switch connector H-05 (terminals 12) and 
ETACS-ECU connector D-223 (terminals 53).
Q: Is the wiring harness between power window main 

switch connector H-05 (terminals 12) and ETACS-ECU 
connector D-223 (terminals 53) 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

the door lock switch should be normal.

STEP 18. Check ETACS-ECU connector D-223 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector D-223 in good condition?

YES : Go to Step 19.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection

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

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.

SIMPLIFIED WIRING SYSTEM (SWS)

54B-616

.

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

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B
