HDC Failure

Hi Guys

Upon starting my Discovery up I get the brief error message is HDC not available. Obviously Hill Decent Control

What would cause this commonly ? I've recently had all new discs and breaks fitted so I'm a little unsure

Probably a wheel speed sensor will have to get codes read to replace the correct one. Probably got broken on changing brakes by whomever.

I think you will find it will most be a weak battery Thumbs Up

SAS is the Steering Angle Sensor and it needs a disgostic tool to re-calibrate, but it wouldn't trigger at a standstill. As suggested above, check your battery and alternator voltages. Thumbs Up

Guys, few years down the line and I’ve put a brand new battery on the motor and ya-da the HDC warning light is no more... you guys were right again 👍

Thank you

I used to get this on my FL2 especially when the weather was cold cured it by getting an addition earth strap attached if I remember right it was attached to the alternator body
