HDC (Hill Descent Control) fault in your Range Rover typically indicates a problem with the braking system, ABS sensors, or battery voltage. This warning often appears on the dashboard when the system is unable to engage properly, especially on uneven or steep terrain. It may be accompanied by other warning lights like traction control or suspension faults. Prompt diagnosis is essential to ensure safe off-road and hill driving. At Cerrones European (or your preferred company), we provide expert diagnostics and repairs for HDC and other Range Rover electronic systems.
