STEP 7. Check the wiring harness between power window
main switch connector E-12 (terminals 5 and 10) and
ETACS-ECU connector C-217 (terminals 33 and 34).

NOTE: Also check intermediate connector C-26 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-26 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

Q: Is the wiring harness between power window main

switch connector E-12 (terminals 5 and 10) and
ETACS-ECU connector C-217 (terminals 33 and 34) in
good condition?
YES : Replace the ETACS-ECU. If the central door locking

system works normally, input signal from the door lock
switch (power window main 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 (power window main switch)
should be normal.

STEP 8. Check power window sub switch connector E-04
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window sub switch connector E-04 in good

condition?
YES : Go to Step 9.
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 (front
power window sub switch) should be normal.

STEP 9. Check the door lock switch (front power window
sub switch).
Remove the front power window sub switch. Refer to GROUP
42, Door, Door Glass and Regulator

P.42-39

. Then check con-

tinuity between the switch terminals.

Q: Is the door lock switch (front power window sub switch)

in good condition?
YES : Go to Step 10.
NO : Replace the front power window sub switch. If the

central door locking system works normally, input
signal from the door lock switch (front power window
sub switch) should be normal.

STEP 10. Check the ground circuit to the front power
window sub switch. Measure the resistance at front power
window sub switch connector E-04.
(1) Disconnect front power window sub switch connector E-04

and measure the resistance available at the wiring harness
side of the connector.

(2) Measure the resistance value between terminal 2 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 12.
NO : Go to Step 11.

STEP 11. Check the wiring harness between front power
window sub switch E-04 (terminal 2) and ground.

.

Q: Is the wiring harness between front power window sub

switch connector E-04 (terminal 2) and ground in good
condition?
YES : No action is necessary and testing is complete.
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 12. Check ETACS-ECU connector C-217 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-217 in good condition?

YES : Go to Step 13.
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 (front
power window sub switch) should be normal.
