What's the matter with the HDC transmission failure?

[LeDawson]

HDC stands for Hill Descent Control system failure. The principle of this HDC system is to combine engine braking with the ABS system to maintain a low speed without losing tire grip when the vehicle is descending a steep slope. If a failure occurs, it is recommended to promptly visit a 4S shop for inspection and repair. HDC system setup: The HDC system must be set up before entering steep slope conditions, allowing the driver to focus entirely on steering. After the HDC system is set up: When the HDC system is activated, no pedals need to be pressed when descending a steep slope. The vehicle will automatically move forward slowly at a speed of 8-9 kilometers per hour. At this time, no control over the throttle or brake is required; the only thing needed is to steer properly.
