ABS Light On

I assume that your coach is on the Workhorse W chassis. An ABS light will still allow your brakes to work fine but you WILL NOT have ABS or anti-lock braking protection. This can be caused by a faulty sensor (about $100) or a dirty connection, etc. The sensors just slide in on the backside of your braking assembly. There is a two wire pig tail that comes off of each sensor that plugs in to the wiring harness. If you have an ohmmeter it is easy to check each sensor. A good sensor will read about 1200 ohms. The sensors just slide in to the back and you may try pushing on the back side to see if one sensor has come a little loose and just moved out. If it has it should slide right back in and problem solved. If you find that you have a bad sensor according to an ohmmeter check, they are available online or at some truck service centers. Mine were made by Meritor but I do not have the specific part number available. Easy enough to change with no tools needed. Just pull the old one out and shove the new one in. Plug in the cable and drive.
