STEP 1. Verify which door switch is defective.
Q: Which door switch signal is not entered?

Power window main switch (Driver's door) : Go to Step

2.

Power window sub switch (Front passenger's door) :

Go to Step 8.

Power window main switch (driver's door) and power
window sub switch (front passenger's door) : Go to Step

14.

Power window main switch (driver's door) and power
window sub switch (front passenger's door) (Lock
signal only) : Go to Step 16.
Power window main switch (driver's door) and power
window sub switch (front passenger's door) (Unlock
signal only) : Go to Step 18.

STEP 2. Check power window main switch connector H-05
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window main switch connector H-05 in good

condition?
YES : Go to Step 3.
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 3. Check the door lock switch (power window main
switch).
Remove the power window main switch. Then check continuity
between the switch terminals.

Q: Is the door lock switch (power window main switch) in

good condition?
YES : Go to Step 4.
NO : Replace the power window main switch. If the central

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

STEP 4. Check the ground circuit to the power window
main switch. Test at power window main switch connector
H-05.
(1) Disconnect power window main switch connector H-05 and

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

(2) Measure the resistance value between terminal 3 and

ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Check the wiring harness between power window
main switch H-05 (terminal 3) and ground.

NOTE: Also check intermediate connector D-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-25 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between power window main

switch connector H-05 (terminal 3) 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 6. 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 7.
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 7. Check the wiring harness between power window
main switch connector H-05 (terminals 10 and 12) and
ETACS-ECU connector D-223 (terminals 54 and 53).

NOTE: Also check intermediate connector D-25 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connectors D-25 is damaged, repair
or replace the damaged component(s) as described in GROUP

.

Q: Is the wiring harness between power window main

switch connector H-05 (terminals 10 and 12) and
ETACS-ECU connector D-223 (terminals 54 and 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.
