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: 1) the power window regulator master switch assembly (built into the driver side door), and 2) the power window regulator switch assembly (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:FUNCTION OUTLINE
Function Outline Manual UP/DOWN function Function that causes window to raise while power window switch is being pulled halfway up, and lower while switch is pushed halfway down. Window stops as soon as switch is released. AUTO UP/DOWN function Function that enables window of all doors to be fully opened or closed by one press or pull of power window switch respectively.
