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.
