What is the reason why the sunroof of the eighth-generation Accord can open but not close?

It is because the car's anti-pinch function is activated; simply turn off the anti-pinch function. Below are some related additional details: 1. The function of power windows: On one hand, it is to reduce the labor intensity of the driver and passengers, making operation very convenient; on the other hand, the rising speed of power windows is relatively fast, which may lead to accidents where passengers could get pinched. The anti-pinch function of power windows can safely address the potential hazards caused by power windows. When a car window encounters an obstacle while rising, it can automatically retreat to the bottom, preventing accidents. Many window anti-pinch functions use Hall sensors to determine the position of the glass. During the process of the car window glass rising, if something blocks the glass from rising, it will immediately stop rising. 2. The principle of the anti-pinch function: An additional set of current sensors is installed, with Hall sensors continuously monitoring the motor's speed. When the power window rises and the motor speed slows down, the Hall sensor detects the change in speed and reports it to the ECU. The ECU then sends instructions to the relay, causing the current to reverse, which stops or reverses (lowers) the motor. As a result, the window stops moving or lowers, providing a certain degree of anti-pinch functionality.
