How to activate the anti-pinch function for all four windows?

[MatthewLee]

The anti-pinch function for windows is automatically enabled. When the window encounters an obstacle while rising, it will automatically retract to the bottom to prevent accidents. Many window anti-pinch systems use Hall sensors to determine the position of the glass. If an obstruction is detected during the window's ascent, the power window will immediately stop rising and retract to the bottom, achieving the anti-pinch function. The working principle of the window anti-pinch function is as follows: 1. Introduction one: The anti-pinch feature involves installing a current sensor, where the Hall sensor continuously monitors the motor's speed. When the power window rises and the motor's speed decreases. 2. Introduction two: When the Hall sensor detects a change in speed, it reports the information to the ECU. The ECU then sends a command to the relay, causing the current to reverse, which stops or reverses the motor, thereby stopping or lowering the window. This provides a certain degree of anti-pinch functionality.
