System Description/With Interruption
Detection Function
OUTLINE
Power window system consists of
lCPU (combined with power window main switch)
lfour power window regulators
When ignition switch is in the ``ON'' position, power window can be operated depending on power window
sub/main switch condition.
OPERATIVE CONDITION
lPower windows can be raised or lowered with each sub-switch or the power window main switch located
on the driver's door trim when ignition switch is in the ``ON'' position and power window lock switch on
the driver's door trim is unlocked.
lWhen power window lock switch is locked, no windows can be raised or lowered except for driver's side
window.
lWhen ignition switch is in the ``ON'' position, to fully open/close the driver's side window, press down/
pull up completely on the automatic switch (main switch) and release it; it needs not be held. The win-
dow will automatically open/close all the way. To stop the window, pull up/press down then release the
switch.
lAfter turning ignition switch to OFF, the driver's side window can be raised or lowered for 15 minutes.
The timer control for supplying power after turning ignition switch to ``OFF'' will be canceled when the
driver's side door is closed. (Except models for Europe)
INTERRUPTION DETECTION FUNCTION
CPU (combined with power window main switch) monitors the power window regulator motor operation and
the power window position (full closed or other) for driver's power window by the signals from encoder and
limit switch in front power window regulator (driver's side).
When CPU (combined with power window main switch) detects interruption during the following close
operation in the driver's side door,
lautomatic close operation when ignition switch is in the ``ON'' position
lautomatic close operation during power window timer operation
lmanual close operation during power window timer operation
CPU (combined with power window main switch) controls driver's power window regulator motor for open
and the power window will be lowered about 150 mm (5.91 in).
