HDC Warning

[Rev Den]

My 08 RR Sport Super has started chiming and three error messages start displaying. HDC Fault, Transmission Fault and Brake Fault. All warnings lights are yellow. I called my local dealer (375 miles away) and he said my battery is going dead. My battery is 1 year old Interstate. Had the battery tested at an Interstate distributor and they said it is fine, actually testing higher than rated. I can stop the car and restart it and the errors and lights go away only to appear a few hours later. Any ideas?

Go to the dealer to get the codes diagnosed.

It could be anything.

Sorry but its a drive to the dealer.
Most guys don't have the equipment and the know how to fix these vehicles.

when does it happen if it happens when first starting then yes its voltage related. if your driving down the road then your coming to a stop and it comes on then brake switch issue. it can be many possible things but those are the most commen

Are you sure you've identified the lights correctly? HDC is hill descent control. Are the others actually TC in a circle (Traction Control) and ABS, not Brake? If so, just do a search in this forum for the Three Amigos.
