What is the reason why the electronic handbrake of the Trumpchi GS4 cannot be pulled up?

It may be caused by a short circuit of the wiring harness to the positive pole, or the parking brake control unit may be faulty. Here is the relevant introduction: 1. Electronic handbrake: The electronic handbrake is also known as the electronic parking brake system. The Electronic Parking Brake (EPB) integrates the temporary braking during driving and the long-term braking after parking, and realizes the parking braking technology through electronic control. 2. Working principle: The electronic handbrake is a technology that realizes parking braking through electronic control. Its working principle is the same as that of the mechanical handbrake, both of which use the friction generated by the brake disc and the brake pad to control the parking brake, except that the control method has changed from the previous mechanical handbrake lever to an electronic button.
