drove my truck today for lunch every thing was fine i get back into it to get off work and the abs light is on any ideas whats causeing this i just put a pinon seal in it 3 days ago could that have any thing to do with this??

 

could be a bunch of things, mine came on when there was low brake fluid, and one time when I had a blown fuse...

 

yeah break fluid is good so are fuses don;t know fixing to pull the dash and take the light bulb out i hate them idot lights

 

well figured it out today figured i would start cheap sense no one around here could run the codes for me so i try to eleminate it one by one so i went and got a speed sensor for the rear end and boom light is off it was a 14.00 fix im glad it wasent the front ones there 300.00
