STEP 6. Check power window main switch connector H-05 
and ETACS-ECU connector D-223 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Q: Are power window main switch connector H-05 and 

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 
00E, Harness Connector Inspection

.

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.

STEP 8. 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 9.
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 9. 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 10.

STEP 10. 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 11.
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 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 

P.00E-2

.

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.
