How to Reset the Electronic Parking Brake Fault in Haval?

[DiBethany]

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.

I have my own procedure for dealing with Haval electronic parking brake malfunctions. First, ensure the car is parked on level ground in P gear with the ignition turned to the ON position (engine off). Keep the brake pedal fully depressed with your right foot, then toggle the parking brake switch back and forth 7-8 times - this action can wake up the system reset program. If the dashboard warning light persists, perform a complete power reset: disconnect the negative battery terminal for five minutes. After reconnection, drive slowly on flat ground to let the ECU recalibrate brake position parameters. Last time my friend's car still made noise after reset - turned out worn brake pads had triggered the protection mechanism. Electronic parking brakes are sensitive to freezing temperatures and moisture, often giving false alarms after winter snow/rain. Always wear insulated gloves when working to prevent electrical accidents.

My experience with resetting the electronic parking brake is a bit rough but effective: lift the trunk mat to locate the emergency release loop, and with a deft pull, you can manually disengage the brake lock. However, this method is only for emergencies. A proper reset requires the 'power-off method.' After restarting, pay special attention to the clicking self-test sounds from the system the moment you start the car—do not touch the brake button during this time. Once, I was too hasty and pressed the button, causing the fault light to come back on. To confirm a successful reset, test drive the car: gently pull the handbrake at 20 km/h, and the vehicle should brake smoothly. Also, remember to check the brake fluid level, as low fluid can cause the electronic module to act up.
