PaulXyZ and AV Xterra,

Is your brake fluid level OK? I've had the Slip and VDC light come on (along with the Brake light) when I had a leaking rear brake hose. At first it was intermittent until the fluid got low enough, then they were on all the time.

If the fluid level is OK, the only thing I can think of is some sort of electrical problem - short circuit, perhaps.
