STEP 8. Check power window sub switch connector H-16
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window sub switch connector H-16 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 should
be normal.

STEP 9. Check the door lock switch (power window sub
switch).
Remove the power window sub switch. Then check continuity
between the switch terminals.

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

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

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

STEP 10. Check the ground circuit to the power window
sub switch. Test at power window sub switch connector
H-16.
(1) Disconnect power window sub switch connector H-16 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 equal 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 power window
sub switch H-16 (terminal 2) and ground.

NOTE: Also check intermediate connector D-15 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connectors D-15 is damaged, Repair
or replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection

.

Q: Is the wiring harness between power window sub

switch connector H-16 (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 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 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 should
be normal.

STEP 13. Check the wiring harness between power
window sub-switch connector H-16 (terminals 1 and 3) and
ETACS-ECU connector D-223 (terminals 53 and 54).

NOTE: Also check intermediate connector D-15 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connectors D-15 is damaged, Repair
or replace the damaged component(s) as described in GROUP

Q: Is the wiring harness between power window

sub-switch connector H-16 (terminals 1 and 3) and
ETACS-ECU connector D-223 (terminals 53 and 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.
