This is the problem, the ABS indicator is allways turn on but the vehicle works normally, can some body tell me the posible reasons, and how can I fix it.

 

I'm not sure if this helps but I had the same thing happen 2 different times on my 98 cherokee. The firtst time it was the plug the attaches to the Dash console. The clips had cracked and the cable had to be replaced. The second time was the the rear ABS senser was crack and had to be replace. Have you tried attaching it a computer to check the for codes. If you don't have one, some autoparts stores have ones you can borrow or rent. If you live by an Autozone they will check it for free. Like said this not an snwser but hope it helps and point you in some kind of direction.

 

[Ok thanks Sr for your help.
