Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Auto Reverse Operation
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 (pulser), the driver's power window control unit makes the power window motor stop and reverse. If the window is more than halfway closed, it will reverse to half open position. If the window is more than halfway closed, it will stop and reverse about 2 inches. This is to prevent pinching an obstacle during auto-up operation. This auto reverse operation is not active when the driver's power window switch is held in the close position.
