Coach & Powertrain: ABS Light
March 27, 2012
Filed under RV Tech Q&A
I have a 1995 Damon Ultra Sport motorhome. Ever since I bought it in 2001, the anti-lock braking (ABS) warning light comes on, sometimes after driving it for several miles, or maybe even just a couple of miles. Once I stop and turn the engine off, then start again the light will stay off for a while. Sometimes I can hit the brakes several times during a trip and the light stays off. Then other times, the first time I hit the brakes the light comes on and stays on until I stop again. The brakes work fine. I have put over 20,000 miles on it since I bought it, but it’s annoying. Do you think maybe a sensor is going bad?

The ABS light indicates the computer has detected a problem. You have to use a scan tool designed for ABS. It will tell you what the stored trouble code is, and thus the problem area. The most common problems are wheel-speed sensors, which often get covered with crud and iron dust from the rotors.
