My anti-lock brake light is on. My brakes are functioning properly. I read the manual and all it does is try to scare you into towing it to the dealer. Does anyone know how to make the light go off?

thanks

 

It Could Be A Number Of Problems, But The Main Question: Is Do The ABS Brakes Work?

If So, Then Its Most Likely A Wiring Problem That Could Be In Various Places

If Not, Again It Could Be The Wiring, But Also: The Control Module, Wiring On The Rotor (Previous Chevy Experiences) Or Anything In Between, I Would Get It Scoped And Checked Out By A Mechanic If They Aren't Working Properly, And If You Don't Need Them. Brake On Your Own Terms On Ice, Snow, Water, Etc.

Hope This Helps

As previously stated it could be a number of problems... The only way to figure out what is causing it is to get someone with a scan tool that can scan the anti lock system.

The anti lock light is on in my car too. Upon scanning it turns out that one of the solenoid is "open or short to the battery" and the right rear wheel sensor is bad. I've been meaning to troubleshoot it further but haven't got around to it.

The following is what I intend to do:


Short of a scan tool the only thing that I can think of is going through each of the wheel sensors one by one and seeing if they work.

I'm not 100% sure (a.k.a. educated guess) but I'd bet money that the wheel sensors work off frequency modulation. That means that with power to the system on (The key to on or maybe the engine running. I'm not sure which.) you should have a voltage at each of the sensors. If you unplug the sensor and put a voltmeter across the terminals you should get a voltage. If you do this for each sensor it would eliminate wiring to the sensors as the problem.

You could try back probing the plugs to the sensors with a freq. (if you have one. If not they're about $60.) meter and see if you get different readings as you spin the wheels.

I'm not really sure how to test the abs solenoids. I plan on figuring it out in the next week or two. I'll get back to you on that one. I've got some spare ones sitting around that I can play with.

The only other possibility is a bad abs computer. I think in my 1996 lumina the computer is located under the passenger seat. The only way I can think to test that is a scan tool or to replace it and see if it fixes the problem.

Hope this helps!! If anyone has any corrections to anything I said they would be much appreciated!!
