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.

Logic says it should be, since it’s part of the car as it was sold brand new. However, some manufacturers place conditions on this, mainly in terms of parts that are subject to general wear and tear. For that reason, tyres, brake pads and batteries are usually not covered by a new-car warranty.

Exceptions are also sometimes made for accessories fitted to the vehicle. But even if your TPMS was fitted as a genuine Haval factory accessory, GWM's (Haval's parent company's) warranty terms spell it all out pretty clearly:

“GWM Genuine Accessories purchased and fitted to a vehicle by a GWM Authorised Dealer are warranted for the remainder of the New Vehicle Warranty or 12 months from the date of purchase, whichever is greater. “

Put simply, even if the TPMS was considered an accessory rather than standard equipment, if it was a genuine Haval system, it should still be covered by the car’s factory warranty

If you have a look through the owner’s manual of the vehicle, you might find a method of using the info-screen menus to achieve this. It’s more likely, however, that you’ll need to plug the appropriate scanning tool into the car’s diagnostic port to reset this reminder light. At which point it’s not a home-driveway job.

I’m guessing that you had the car serviced at an independent workshop rather than a Haval dealership, as the latter would have known the procedure to reset the light. Which is fair enough as Haval does not have the dealership coverage of a car-maker like, say, Toyota or Ford. The point being that you need to make sure that any workshop you use for servicing while the car is under factory warranty, is licensed and certified to stamp your service handbook to keep your warranty valid. You don’t have to use a Haval dealer, but the workshop you choose needs to be a professional operation or you stand to kiss your warranty goodbye.
