Most common cause is a wheel sensor issue. Visually look at the sensor wires - are any pulled loose/hanging. The sensor can also read faulty if the sensor gap (between the sensor head and tone ring) is too large, or if enough metal dust collects on the magnetic head of the sensor.

You should be able to run a self diagnostic (press the ABS diagnostic button and count the ABS warning lamp flashes).

Look for a button like this under the dash (the two buttons at the top are the ABS diagnostic buttons (one is for the Tag)

Here is a link to your manual if you don't have a copy.

On page 347 it has a description of the ABS system including fault codes. On page 348 it shows the ABS module located in your front drivers side run bay. Follow the instructions to try and retrieve the fault codes. If you do get a fault code you'll have to do a search for the code or post here and we should be able to help you with it.

I had a problem last month with mine, I hadn't driven for ~6 months and the ABS light stayed on. When I went to try and retrieve the fault codes I felt the button sticking. It had done this before, I rapidly pressed the button until it was free and the light went out. Dirt gets in around the button and vibration ultimately holds in in causing the light to stay on.

The last time I actually had a fault code it showed the front drivers side sensor as being bad. I pulled he sensor, reinstalled, and reset into the hole, pushing it all the way in tight. I then drove the coach and the ABS light went out.

Just had this problem. On my '04 Ambassador the ABS board is located in the lower left corner of the electrical bay on the left side below the driver's area. If pressing the test light doesn't initiate the ABS test (mine did nothing) it could be that little board. NW RV supply had a 'repair only' option for this board. It costs $114, if they can't fix it you'll get a $44 rebate. They were able to fix mine, 1200 miles and no problems, ABS light out. Good luck, safe travels.
