How to Reset the Haval Electronic Parking Brake Malfunction?
4 Answers
Haval electronic parking brake malfunction reset solution: Go to a 4S shop to read the fault code with a decoder and repair according to the fault code. The electronic parking brake 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 achieve control of parking braking through the friction generated by the brake disc and brake pads. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. The Haval H2 is a compact SUV under Great Wall Motors. Taking the Haval H2 2018 1.5T manual two-wheel-drive fashion model as an example, its length, width, and height are 4365mm, 1814mm, and 1710mm respectively, with a wheelbase of 2560mm. In terms of power, the Haval H2 2018 1.5T manual two-wheel-drive fashion model is equipped with a 1.5L inline four-cylinder turbocharged engine, with a maximum power of 110kw and a maximum torque of 210nm, matched with a 6-speed manual transmission, and the driving method adopts front-wheel drive.
When my Haval H6's electronic parking brake malfunctioned, the warning light kept flashing. I first turned off the engine, removed the key, and ensured the car was stationary. Then, I opened the hood, located the battery, used a wrench to loosen and remove the negative terminal, and left it disconnected for 10 minutes to allow a complete reset. While waiting, I took the opportunity to briefly check the fuses or connection points for any looseness, as damp weather or an aging battery can often cause issues. After reconnecting the terminal, I started the engine and tested the parking brake button several times to see if it would release normally. This method has resolved several minor malfunctions for me, saving both time and money. However, remember not to drive immediately after resetting the parking brake—test it multiple times to confirm it's working properly. Frequent malfunctions might indicate a damaged sensor, requiring a visit to the shop for inspection. Since the electronic parking brake relies on electrical power, maintaining the battery is crucial to avoid power loss and potential risks.
The method to reset an electronic parking brake failure is simple: turn off the engine, remove the key, open the hood, disconnect the negative battery terminal, release the buckle, and leave it for 10 minutes to reset the system. After reconnecting, start the engine and test the button function. Ensure safety during operation, and park the car on a stable surface to prevent sliding. My experience: power disconnection can clear temporary bugs, but if the warning light persists, consult the manual or visit a repair shop—don't ignore it. Electronic parking brakes rely on signals; low voltage or rainy/snowy weather increases failure risks. After resetting, maintain the battery and connections regularly for reliability. Before driving, manually test the release for smooth operation—handling minor issues yourself is efficient and effective.
When the Haval electronic parking brake malfunctions, reset by power interruption: turn off the engine, disconnect the negative battery terminal for 10 minutes, then reconnect and test the button. Prevention is key: maintain sufficient battery charge, check connection tightness, and even after successful reset, consult the manual for guidance to minimize risks. Safety first—do not attempt to drive with a malfunctioning system.
