Abs light stays on and tracks off lights is on in a car i test drove, what does this mean

no information generic answer have vehicle scanned ---check brake fluid level / condition --brakes --abs sensors--hubs

The ABS carries out a self-test when the ignition is switched on. If no faults are found the light will go out. If the light stays on it means a fault has been discovered, recorded and the ABS will be switched off.

To rectify this condition the fault will have to be identified by a code read, the fault repaired and the fault code erased.

gmc envoy i had done the same wound up replacing all four wheel brake pads and light stayed off

All the computers on the car are linked together. The ABS can trigger the service light on some applications, ie speed sensors. You can still drive, but you wont have ABS, meaning if you brake hard enough or in gravel the tires can lock up and skid.

ur blake light switch needs replaced I had same problem.

yes its better to go shop and check what is the code so that u can easy to diagnose and repair..some problem of the abs light come in out is some abs defective or loose ,,or the abs motor ssy have problem or sensors in the wheel.

when the ABS light stays on it means there is a fault present in the ABS system and the ABS has been disabled, as long as the light is on u just have regular brakes with no ABS, there are many thinbgs that can turn the light on, most common is one of the wheel speed sensors is defective, since these sensors are about $75-100 each and there are 4 of them guessing is a poor idea, so what u need to do is have the ABS systwem tested, there will be a fault code present to help narrow down the defective part or wiring.

it might be a loose abs cable behind one of the brakes?

MAKE SURE YOUR CAR BATTERY AND ALTERNATOR IS IN GOOD OPERATION.HAVE THEM TESTED.I HAVE SEEN A CAR WITH ABS AND AMPS LIGHTS ON.THE ALTERNATOR WAS NOT PUTTING OUT ENOUGH VOLTS TO RUN THE ABS BRAKE SYSTEM. IF ALTERNATOR AND BATTERY IS GOOD.I WOULD REPLACE THE ABS RELAY FIRST.ITS GOES BAD CAUSE THE ABS BRAKES NOT TO WORK.IF ABS RELAY IS GOOD.THEN IT HAS TO BE ABS MODULE GOING BAD.IT HAS TO BE REPLACED.

It sounds like you have a faulty ABCM or anti-lock braking control mechanism. 2003 was a common year for failure of this. Usually your car will drive just fine, however, your ABS and traction control might not work as well as there supposed too in a collision.
