OBSTACLE
The system is composed of the power window master switch and the driver’s power window motor.
The driver’s power window motor incorporates a Hall IC unit (pulser) which generates pulses during the motor’s
operation and sends the pulses to the driver’s power window control unit. As soon as the power window control unit
detects a change in the pulse frequency from the Hall IC unit, the power window control unit makes the driver’s power
window motor stop and r
everse. If the window is more than halfway closed, it will r everse to half open position. If the
window is less than halfway closed, it will stop and r everse about 50 mm (2 in.). This prevents pinching your hand or
fingers during auto-up operation. The auto reverse operation is not active when the switch is held in the up position.
