Question about 2001 Chevrolet Malibu
ABS light stays on when car is started . What is the problem or solutions to check or what part or sensor should be replaced ?
The abs light can be on because of a faulty wheel sensor or drive-line sensor, when the ABS light comes on the car goes into emergency mode which means it will work like standard brakes and will lock up the wheels, the ABS is disabled so to check it you need to have an ohm meter and test each wheel to see if the wheel is putting out 2.5 volts on each wheel DC. if not that wheel has a problem either the senor got broke because someone ran over something and broke it off or the connectors are full of mud and can't make contact so unplug them and clean them one by one if you find one that is broken replace it turn the key on and off to the run position 5 times then start the car and drive the light should go off it that fixed the problem, if it does not then it needs to be looked at by someone who knows anti-lock braking systems as they are computerized have high pressure and can cost a fortune if you don't know how to test them properly, I suggested the test for the wheel sensors as this is the most common cause so if yo unhook the connector to each wheel and jack up that wheel so you can turn it you can test it for voltage at the sensor ring, with the test meter on 5 volts DC you won't damage anything so that is as far as you should go unless you buy a subscription to all-data for your car and read all the information on the abs system, if you wish to do so and see the recommended price for parts and labor then go to http://www.alldatadiy.com

The ABS light is a warning that there is a problem with the system. There are so many things that can cause this that guessing is a bad and expensive idea. If you can get it scanned for codes I can give you a direction to go. Auto Zone will scan it for free. Get me a code and I will be glad to help. Good Luck.
