I have a Hill Descent Control fault in my 2020 Haval H2. Should I be worried?

The HDC refers to the Hill Descent Control feature that allows the vehicle to crawl down a steep slope off-road without the driver applying the brakes. This function uses the car’s braking and ABS systems to operate, so any fault with it has serious implications for the vehicle’s overall safety.

You may have a dud sensor or something wrong with the wiring, electronics or even the hardware. Either way, an electronic scan should give you a few clues as to what’s causing this fault message to show up. Sometimes something as simple as a battery with low voltage can cause error messages like this to appear. But don’t ignore it; these are important safety systems and you need to know they’re working properly.
