What to Do When the Haval H6 Auto Hold Malfunctions?
3 Answers
Haval H6 auto hold malfunction may be caused by issues with the electronic parking brake, worn brake pads, or problems with the electronic system. It is necessary to visit a repair shop to use a decoder to read the fault codes and perform repairs based on the fault codes. Below are some relevant details about the Haval H6: 1. The Haval H6 has a body size of 4640×1825×1690mm and a wheelbase of 2680mm. 2. The Haval H6 is equipped with a 1.5GDIT-EVO engine, with a maximum torque output range expanded to 1400-3600rpm, and is paired with a second-generation 7DCT transmission, achieving a comprehensive transmission efficiency of up to 95.6%.
When driving my Haval H6, I encountered an automatic parking brake malfunction where the car couldn't stay stationary on slopes or the brake lights kept staying on, which was quite annoying. Common causes of automatic parking brake failure include sensors clogged with dust or poor circuit contact. If warning lights flash when starting the car, such as the yellow triangle warning symbol, first try restarting the engine: turn it off for a minute and then restart to see if the system recovers. If that doesn't work, check the brake fluid level—open the hood and locate the master cylinder; if the fluid is low, top it up, remembering to use DOT4 fluid. A weak battery in the H6 can also cause electronic control issues—measure the battery voltage, and if it's below 12V, recharge or replace it. If the problem persists, don't push it—especially during long trips or on slippery roads, manually engaging the handbrake is safer. Immediately drive to a 4S shop and have technicians use a computer to read the fault codes; they can fix software bugs or repair/replace sensors. When washing the car, avoid spraying water into the sensor areas under the chassis to prevent dirt buildup that could trigger malfunctions.
As a car enthusiast, I believe the automatic parking malfunction in the Haval H6 may stem from the vehicle's inherent technical characteristics. The automatic parking system relies on the collaboration of multiple sensors and braking modules, with faults commonly arising from interrupted signals in the electronic control unit or aging wiring. First, check the dashboard for any ABS or ESP error warnings; if present, note the fault codes for subsequent troubleshooting. Try reactivating the system: after parking on a level surface, press the automatic parking button multiple times to test the start-stop function. Checking the vehicle's battery status is crucial, as voltage instability can affect electronic braking; use a multimeter to assess battery health—output voltage below 12.8V requires attention. The H6's user manual recommends regular software updates; I've resolved similar issues by refreshing the firmware via an OBD device connected to the infotainment system. If self-checks prove ineffective, don't overlook potential braking risks—contact a Haval service center for comprehensive diagnostics, as they can calibrate sensors or replace faulty components.
