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?

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

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
