STEP 9. Check power window main switch connector E-04
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window main switch connector E-04 in good

condition?
YES : Go to Step 10.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. The power windows function should now

work normally.

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

measure the resistance available at the 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 power window
main switch E-04 (terminal 2) and ground.

NOTE: Also check intermediate connectors C-12 for loose, cor-
roded or damaged terminals, or terminals pushed back in the
connectors. If intermediate connector C-12 is damaged, repair
or replace the damaged component(s) as described in GROUP

Q: Is the wiring harness between power window main

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. The power
windows function should now work normally.

STEP 12. Check the battery power supply circuit to the
power window main switch. Measure the voltage at power
window main switch connector E-04.
(1) Disconnect power window main switch connector E-04 and

measure the voltage available at the harness side of the
connector.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 10 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Replace the power window main switch. The power

windows function should now work normally.

NO : Go to Step 13.

STEP 13. Check ETACS-ECU connector C-219 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-219 in good condition?

YES : Go to Step 14.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. The power windows function should now

work normally.

STEP 14. Check the wiring harness between power
window relay connector C-203 (terminal 4) and power
window main switch connector E-04 (terminal 10).

NOTE: Also check junction block connector C-215 and inter-
mediate connectors C-12 for loose, corroded or damaged ter-
minals, or terminals pushed back in the connectors. If junction
block connector C-215 or intermediate connector C-12 is dam-
aged, repair or replace the damaged component(s) as
described in GROUP 00E, Harness Connector Inspection

.

Q: Is the wiring harness between power window relay

connector C-203 (terminal 4) and power window main
switch connector E-04 (terminal 10) in good condition?
YES : Replace the ETACS-ECU. The power windows

function should now work normally.

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. The power
windows function should now work normally.
