POWER WINDOW TIMER FUNCTION
(1)
If the ignition switch is placed in the ON position,
the transistor Trl is turned ON and the power
window relay is also turned ON, allowing the
power window to be opened/closed by the power
window switch (main or sub switch).
(2) Turning the ignition switch from ON to OFF will
turn OFF the transistor Trl. At this time, the
ignition switch signal inverted by NOT to H is
applied to AND. In addition, when all doors and
liftgate
are closed, the H signal from the door
switches and the luggage compartment light
switch is also applied to AND. Therefore, AND
outputs the H signal to operate the timer circuit
and turn on the transistor Tr2 for 30 seconds,
allowing the window to be opened and closed.
(3) If any door or the
liftgate
is opened while the
timer is in operation, the L signal from the door
switch or luggage compartment light switch*
is applied to AND. Therefore, AND outputs the
L signal to stop operation of the timer circuit.
As a result, the transistor Tr2 is turned off, mak-
ing it impossible to open and close the window.
NOTE
*:
On vehicles with theft-alarm system, the lug-
gage compartment light switch is the
liftgate
switch.
