1 Amber light is ether the throttle pedal switch or the throttle pot.

Also worth replacing the brake light switch, this can play havoc with HDC and TC lights. There is a sticky about "the three amigos fault" at the top of the section which tells you exactly which parts you need .

If it's the same as the V6, according to the workshop manual, the HDC light on its own means "HDC Relay Fault" or "Throttle sticking".

I guess you'd notice a sticking throttle though!

Well originally did stick at about three thousand rectified that by pressing pedal five times to reset now back to about 750 tickover could cable adjustment be the problem as its slack when idling been out today tc light now off so just hdc on again
