id091200802200

Passenger’s Side

1. Measure the voltage at each terminal (other than terminals H and I).

and related wiring harnesses.

2. Disconnect the negative battery cable.
3. Inspect the power window subswitch connector for continuity at terminals H and I.
4. If the system does not work properly even though 

the inspection items or related wiring harnesses 
do not have any malfunction, replace the power 
window subswitch.

POWER WINDOW INITIALIZATION PROCEDURE

id091200807400

Note

• Initial setting must be performed for the switch of each window front and rear.

• If the following operations have been performed, initial setting is reset, and auto up/down and two-step 

down operation are disabled. Therefore, performing initial setting is necessary.

— Negative battery cable disconnected or power window system power supply fuse removed. (perform 

initial setting for the switches of all seats.)

— Power window switch connector disconnected. (Perform initial setting for the switch connected with the 

connector.)

— Prolonged open/close operation of the power window main or sub switches causes the circuit breaker 

to activate and automatic operation is disabled.

1. Turn the ignition switch to the ON position.
2. Press the switch of each window and fully open the door glass.
3. Pull the switch of each window to the manual-up position to fully close the door glass, and keep holding the 

switch up at the position for approx. 2 s.
