The ABS (anti-lock brake system) light comes on because the computer has detected a problem and set a code. The code will stay in the computer even if the light goes out. You need to have the system Scanned for codes. Once the cause of the code has been repaired the light can be shut off by clearing the code.
Most auto repair shops will have Scanners and all the equipment to Diagnose and repair the problem. And, Most auto parts stores can plug in a diagnostic scanning device into your vehicle to read the trouble codes at no cost if you purchase the parts necessary to repair the vehicle from them. The trouble codes can tell you THE AREA where the problem is with your ABS system. So it's wise to have a Tech check that circuit to isolate what the problem actually is.
In order to reset this light you need to have access to a Scan tool that does more than just read the codes. Other diagnostic equipment may be needed as well.
This Light stands for Anti-lock Brake System. When the light is on after the vehicle has been running a few minutes it means that the on-board computer has picked up a problem in the system somewhere and has set a trouble code for it. Without a scanner tool, it's very difficult to track down and fix the problem so I'd recommend you take it to a trusted mechanic for further diagnostics. Good Luck, some of these fixes are relatively inexpensive then some are not depending on were the problem lies.
