How to Reset the Electronic Parking Brake Fault in Haval?
2 Answers
To reset the electronic parking brake fault in Haval, you need to visit a 4S dealership to read the fault codes using a diagnostic scanner and perform repairs accordingly. The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both utilizing the friction generated between the brake disc and brake pads to control parking braking. The only difference is that the control method has changed from the traditional mechanical handbrake lever to an electronic button. Taking the 2021 Haval H6 third-generation 2.0T automatic two-wheel-drive Max as an example, its dimensions are 4653mm in length, 1886mm in width, and 1730mm in height, with a wheelbase of 2738mm. It is equipped with a 2.0T turbocharged engine, delivering a maximum power of 155kW and a maximum torque of 325Nm, paired with a 7-speed dual-clutch transmission.
I recently dealt with the issue of resetting the electronic parking brake on my Haval. My method was to first completely turn off the car, then open the hood to locate the battery, loosen the negative terminal with a wrench, and disconnect it. I waited about fifteen minutes to allow the system to fully power down, which clears and resets the vehicle's computer data. After reconnecting the negative terminal, I started the car. The key step here is to press the brake pedal and operate the parking brake button three to five times in a row—it's like giving the system a reset exercise. Usually, after this procedure, the fault light turns off. Of course, details may vary for different model years; my 2017 H6 was fixed this way. Remember not to spray high-pressure water directly on the brake components when washing the car, as the electronic modules can act up when wet. If the issue persists, it's best to have a professional read the fault codes, since parking brake problems are critical to driving safety.
