POWER WINDOW DIAGNOSIS

INTRODUCTION TO POWER WINDOWS DIAGNOSIS

M1429002600148

 If the power windows cannot be operated, the fuse, 
relay, main switch, sub switch, ETACS-ECU or motor 
may be faulty.
 When the power window switch (main or sub) is 
operated, the power window motor operates and 
opens or closes the door window.
A timer function has been provided to allow the door 
windows to be opened or closed in 30 seconds after 
the ignition switch is turned from "ON" to "LOCK" 
(OFF) position when a front door <LH> and <RH> is 
closed (door switch is OFF). When the lock switch is 
changed from unlock to lock, the door windows can 
only be opened or closed by the power window main 
switch on the driver's side.

If the following types of symptom occur, there may be 
a fault.

• None of the door windows open or close.

• There are door windows that do not open or close 

using the power window (main or sub) switch.

• The windows cannot be opened or closed using 

the power window (main or sub) switch within 30 
seconds after the ignition switch is turned from 
"ON" to "LOCK" (OFF) position.
