ABS light question???

[Sullie250]

So i was driving my truck yesterday for about 20 minutes and when i got to where i was going i was pullin in to a parking spot and my abs light came on. never came on before that. i checked my brake fluid and that was full. i let my truck sit for about an hour came back, started it, and light was off and never came on again. brakes seem to work fine, they are getting low and need to be replaced, but not sure about the light. any ideas??

A good scanner could pull up the ABS history for you but, chances are, one of the sensors output wasn't received.

No Biggie, might happen again/might not, nothing to worry about until it becomes persistent.....

If it starts happening again try replacing the speed sensor in the rear end, it's only like 20 bucks and it's really easy to replace. I know my abs light was coming on because mine went bad. It might not be your problem but like I said it's a easy place to start

thanks for the quick info guys. i drove around quite a bit today with a decent sized load in my truck and the light never came on again. hopefully it wont.

Mine comes on once in a while. Its a bad sensor Im pretty sure. My brakes are fine.

I have a ABS light problem to, I had the rear wheel seals replaced, the light was on before and after that, and I replaced the rear brakes. The light is always on, it was on before I bought it, so what is the speed sensor do in the rear end to cause the light to come on? What else could cause it to stay on?

You may also have a problem with a Front ABS sensor. Take a look at the top of the front hubs. If you have a wire that comes out of the hub and goes up to the inner well and then down to the back, bottom of the well (by the rocker panel), one of those could be bad.

Could even be the entire ABS unit too....

The rear speed sensor reads off the abs ring off in your rear end and I'm pretty sure has some control over your speedo, when mine went out the speedo would bounce around till I got up till aroun 50mph other than that and light being on I could never tell anything else... Like I said it's only 20 bucks and one 1/2" bolt and it's replaced

the abs light on my 03 would come on randomly and go off on its own. somebody with a scan tool would be able see which abs sensor is not reading correctly.
