NOTE: Also check junction block connector C-211 for loose, 
corroded or damaged terminals, or terminals pushed back in 
the connector. If junction block connector C-211 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 relay 

connector C-203 (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. The power 
windows function should now work normally.

STEP 9. Check power window main switch connector E-12 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q: Is power window main switch connector E-12 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-12.

(1) Disconnect power window main switch connector E-12 and 

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

(2) Measure the resistance value between terminal 12 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-12 (terminal 12) and ground.

NOTE: Also check intermediate connectors C-26 for loose, cor-
roded or damaged terminals, or terminals pushed back in the 
connectors. If intermediate connector C-26 is damaged, repair 
or replace the damaged component(s) as described in GROUP

STEP 12. Check the battery power supply circuit to the 
power window main switch. Measure the voltage at power 
window main switch connector E-12.

(1) Disconnect power window main switch connector E-12 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 13 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.
