COMPONENTS PARTS AND FUNCTION
Electronic Control Unit (ECU)
ignition Switch (ON position)
The ECU switches transistor Trr ON when the ignition key is at the ON
position, and for about 30 seconds after the ignition key is turned to the
OFF position, thus maintaining the power window relay in the ON condi-
tion.
Note that the timer is stopped if a door is opened during timer operation
(about 30 seconds).
_
Sends HIGH signals to the ECU (when the ignition key is at ON only),
for system compulsory activation input and timer start condition.
Door Switch
(left and right)
Detect the open/closed condition of the doors.
These switches are switched ON when the doors are opened, and send
ground signals to the ECU.
When these signals are input during the 30-second operation time of
the delay timer, the ECU switches OFF transistorTr1' thus switching
OFF the power window relay.
';~~/z~~6s9
Located in the relay box at the left front part of the engine compartment.
This relay is activated by the ECU; power is supplied, via fuse No.8,
from the battery.
In addition, when this relay is ON, power is supplied to the power windov
circuit, via the sub fusible link 1 from the battery.
Power Window Switches
/Power Window Motors
These switches and motors are activated when the
power window relay is switched ON;, the direction of conductivity to
the motors is switched by the operatron of each switch, thus opening ant
closing the windows.
