OPERATION

0When, with the ignition switch at the ON
position, a power-window (main or sub) switch
(“UP” side or “DOWN” side) is pressed, current
flows through sub-fusible link No. 8 and to the
power-window motor, thus causing the door
window glass to close or open.
When the “DOWN” side of the power-window
main switch at the driver’s side is pressed all the
way, it is locked at the pressed-in position, and
the power-window motor operates until the
door glass is fully opened.
When the power-window lock switch is set to
the “LOCK (ON)” position, the power-window
motor will not operate if any switch (main or sub)
other than at the driver’s side is operated.
A circuit breaker is provided in the power-window motor in order to prevent damage to the
motor as a result of excessive current.
For reference: Circuit breaker characteristics
Motor operation is restricted at high
temperatures
:
[20 - 25°C (68 - 77”F)].Current flow is cut by an initial current
occurs within 60 seconds if then left as
Iflow time of four to 40 seconds; resetis.The timer function of the ETACS permits the
power-window relay to remain ON for 30
seconds after the ignition switch is switched
OFF.If, during that period of time, the front door is
opened, the power-window relay is switched
OFF, and the power windows can no longer be
operated.
TROUBLESHOOTING HINTS1. All door windows cannot be opened or closed.
l Check sub-fusible link No. 8.
l Check the power-window relay.
l Check the power-window main switch.
2.One of the door windows cannot be opened or
closed.
(1) Neither of the power-window switches
(main or sub) operates.
l Check the power-window main switch.
lCheck the power-window motor for the
power window that does not operate.
(2) Either the power-window main switch or
sub switch does not operate.
lCheck the power-window switch for the
power window that does not operate.
3. The one-touch down switch function only does
not operate.
lReplace the power-window main switch.
4.The power window operation by ETACS control
after the ignition switch is switched OFF does
not function.
l Refer to
P.42-43.

BODY - Troubleshooting
OPERATIONl When the door lock switch is set to the LOCK side (or
UNLOCK side), the LOCK side (or UNLOCK side) of the
door lock relay is turned ON and the door actuators of
alIsadoors operate.
lIf the driver seat side door (or assistant seat side door) is
opened and the driver seat side inside lock knob (or
assistant seat side inside lock knob) is locked with the key
inserted in the ignition switch, the ETACS unit grounds the
unlock side circuit of the door lock relay to unlock all doors.
This way, failure to remove the key is prevented.
NOTEThe door lock actuator contains a PTC thermister to prevent
damage caused by overheating of the motor. If the central
door lock is frequently used, the actuator may temporarily
fail to operate. If it returns to normal in a few minutes, it is
not defective.
TROUBLESHOOTING HINTS
1. One of the door lock actuators fails to operate.
l Check the door actuator which fails to operate.
2. The ignition key reminder system does not function.
l For information concerning ETACS control, refer to
P.42-55.

TROUBLESHOOTING GUIDE
INPUT CHECK
Using the multi-use tester or voltmeter, check whether or not
the input signals from each switch are being input to the
ETACS unit.
(I), Connect the multi-use tester to the diagnosis check
connector located at the right side of the junction block or
connect the voltmeter between the ETACS terminal and
the ground terminal.
(2) Check if the buzzer of the multi-use tester sounds or the
needle of the voltmeter moves when each switch noted
below is operated.
If the buzzer sounds or the needle moves, the input signals
are being input to the ETACS unit, so that switch can be
considered to be functioning normally. If not, the switch or
switch input circuit is faulty. Check the switch and the
switch input circuit.
