How do I reset trac off abs light on my 03 chevy montecarlo ss. Changed the wheel bearing and sensor

itll go off but once you start rolling itll come back on it most likely needs a hub assy you need to get code and see what ones bad you have 4 one on each wheel and iv seen each one go bad so get code and get good timkin hub assy

The error could be in transmission abs airbags or engine among others. As many modules these days is staggering. Suggest take it to dealer. Not many mechanic shops have the ability to check codes or repair suspension , airbag or other manufacturer specific design ed systems. And you will get much more knowledgeable mechanic. Could be as simple as wheel bearing loose, most prelevent cause, but without codes from computer making lights come on, were dead in water. Transmission in limp home mode makes me lead to guess, ya just a guess, to say you are missing a speed sensor. Signal. Now car will still start without crank sensor, tourque converter input speed sensor, trans output speed or any of the four abs wheel speed. Like I said loose wheel bearing causes mag pick up wheel speed sensor to miss counts, ad has predetermined amount of pulsed electrical signals it produces, when one not equal to others then pops code. Good luck write what code is found and where. Thx

The abs light comes on when a fault is detected with abs system. Your best bet is to have the abs system scanned for trouble codes. Typically loose wheel bearings, or broken abs sensor harness wires are the two most common causes for the abs light to come on.

Try the brake and trac sensor its the same sensor

When they replaced the wheel bearings there are sensors connecting to the hub I would make sure that the sensors are connected and that there is no corrosion on the connectors.

SERVICE TRACTION CONTROL and NO TRAC light comes on and off. Changed wheel hub and bearings, alignment, brakes, tires...HELP!!!

Either someone damaged a sensor for the ABS/TRAC control, or the replacement parts are not compatible with the ABS system.

Might have a front wheel bearing going out take it to a shop they can hook up a computer and tell you which bearing it is

ABS sensor on wheel hub bearing. I had the same problem cange it and problems went away

Def the wheel bearings/hub/speed sensor. I just bought a new wheel bearing comes with the hub and speed sensor as one. Runs about 80-100 dollars though but abs/traction light went off and stays off now.
