My front Brakes were done last year when I did my LS1 brake swap so they are in good shape and my rear pads are in good shape as well and everything was fine and now all of a sudden I have a ABS light on the car still drives and brakes normal,

any one have any ideas??

 

Anything from a broken sensor harness, bad sensor, dirty contacts, build up of crud around the reluctors, bad ground, etc, etc, etc...

If it's a wheel sensor, a scanner can tell you which one and you can hunt it down from there. Best bet is to get it scanned so you're not wasting time/money.

 

Every three months or so I have the same light. I take out my relay clean the contacts and it goes away. It keeps coming back because I've been too lazy to actually get a good clean contact. Its usually at the side of the road and I scrape it with a knife to remove the light.

 

Thanks for the tips I will try those things that you mentioned out.

 

if by chance you did plug wires any time lately, and you routed one of the driverside wires too close to the abs unit, it will set off the light also.

 

i think I found the prob, I switched to the 98 and up SS wing and the 3rd brake light is now an LED light and the PCM isnt detecting it a light because it dosent draw much amperage, what do you think?

i am gonna try to get a 194 bulb and socket and splice it in to let the PCM know that there is a light working.

any opinions??

 

that sounds right, i remember now, that if your third brake light is out it will also go on.

 

I've heard that also...did the light come on just after you swapped the wing? If so, there's your answer.

 

Yeah it happend right after the wing swap but at the time I didn't realize that a third brake light prob could have caused an ABS light to come on, now that we seemed to have pieced it all together I am confident that the problem is that.

Thanks for the help guy's! and I will let you know if this little experiment works out.
