System Description

POWER WINDOW CONTROL SYSTEM DESCRIPTION

The power window control system controls the power windows' UP/DOWN function using regulator motors.
The main controls of this system are: the power window regulator master switch, which is built into the driver side door, and the power window regulator switch, which is built into the passenger side door. Pressing the regulator switch or either of the 2 switches on the master switch transmits an UP/DOWN signal to the corresponding power window regulator motor.

The jammed window detection mechanism consists of a magnet on the worm gear of the power window motor and the 2 Hall ICs on the motor.
The power window control system has the following functions:
