abs light on

02-13-2003, 02:28 PM
my abs warning light keeps on coming on but when the igniton is turned off it resets itself,wot would be causing this either a crap connection on the abs sensor or possibly damp in the sensor,the brakes still work spot on,i just cant afford to take it to a main dealer at the mo.

My ABS light comes on when I turn my healights on or just my driving lights. I guess it's just some wiring problems.

I've only had the ABS light come one once, but like you said, it reset once I shut it down and restarted. I'm guessing it had to do with water in the circuitry b/c I had been doing reverse donuts and J-turns in about 9" of snow just before the light came on, and I haven't seen it since. How often do you have this problem??? If it isn't very often, I wouldn't worry too much about it. If you're really perplexed about it, I'd run the self-diagnostic code on the ECM and see if it brings up any errors in any of the systems of your G. Hope this helps.

Every time I turn on the lights(headlights). It doesnt come on in the day time.

I've had "ABS light on" issues for about a year myself! I had my G20 at the dealer to check about the Air Bag light and they told me the ABS light was coming on because of a bad sensor (LF) and that I shouldn't worry about it "until it stays on all the time." The NEXT time I had my car in for something (ABS relay, I think), they said it was the RF sensor. Once in a while the light won't come on, but most of the time it comes on about two seconds after I start moving forward. My brakes still work "fine," but I guess my ABS is disabled most of the time because of the bad sensor(s).

Out of curiousity (should I ever try to work on this), anyone know what this sensor looks like? Or where it is? My dad said it wouldn't be at the wheel, but I thought it was at the wheel so it could "sense" if it's locking up...?
