My abs Light just came on. Brakes all seem fine. Question: Bought a 00 TJ auto 4.0. In DEC with 127k on it. Had abs light come on bout 3 months ago...went off after shutting off key then starting again fine. Approx 2 mos ago had rear brakes chged. Tonite, abs light comes on when starting her up! Cycled off on few times light off. Drive 10 miles. Light on for good now. Checked for codes...none found. Any ideas? Thx much. -Tim

Ok I've attached 2 pix off what I think are front abs sensors here. Folks have said they get dirty n must be cleaned....which i have just done. Both pix are from drivers side - 1 after thoroughly cleaning 1 after reinstalling. If you look close the end is mottled/dented compared to pass side. Could this be? If this is the sensor n I've cleaned both...rear has drums didn't see any sensors there... Should I chg this one? What else could poss turn lite on?
 
inspect your tone tuns on the front outter driveshafts. they sometimes like to crack or lose teeth. i had a jeep in the other day that had a cracked ring and it would turn on the shaft itself. sometimes the light would be on, other times it wouldnt.
