Hi all. I have a Nissan Xterra 3.3L V6 2000. I'm concerned about my ABS light. It has been running for about five months now and stays on all the time. My brakes seem to work fine and the brake fluid reservoir is full and stays full so there is no leak. I know it could be a few different things, but I'm open to suggestions as to what the problem might be and how I can fix it. I'm also concerned about the cost of repairs. Any feedback will be greatly appreciated.
