I have a 2000 Silverado with 137K on it. Intermittently, the ABS and Brake dash lights will come on and stay on until the ignition is turned off. There seems to be on pattern to when they come on. They do not effect the operation of the truck. The security dash light has come once, when these lights were on, don't know if there is a relation.

Anyone else experience this? Thanks in advance.

havent had it done to me well YET. but i'd clean the terminals at the wheels maybe dirty or corroding terminals maybe put some elctrical grease in the terminal plugs....good luck

same problem here (except no security) but I suspect my sensors are dirty just haven't taken the time to clean them.

I check around the wheels, but didn't see anything obvious.

sensors are located on knuckle close to cv shaft. (i think) the sensor reads a collar around the cv shaft to determine wheel speed.
