I really doubt the servicing had an effect, but, there is a chance of over-greasing near the wheel and getting grease on the tone-ring.

Often the light is triggered by dirt on the tone-ring, incorrect clearance between wheel sensor and tone-ring.
Without knowing the brand of your ABS system, here is the Meritor-Wabco ABS system service manual for reference.
When I asked a mechanic about my ABS light on, he said to use a high-pressure washer to spray the entire back side of all Wheels on my MH. This will likely wet drum brakes so do not drive your MH for a few hours afterwards. In my case it did work to clean the tone-ring/toothed ring on the back of each wheel.
You may not get the same result.
IMO, This is not a serious issue, as your brakes still work-except the anti-lock brake system is not working properly, but that glaring yellow light is an annoyance when driving.

There should be a method to check the codes on your ABS system. You may check your manual and read that section.

You can get a PDF copy of your manual here
RV Owners Manuals – Holiday Rambler RVs – Holiday Rambler Motorhomes

On page 10-314 it explains how to get the blink codes. You might check to make sure there isn't a change, I found an Adendum on line for my Windsor that had a change to procedure.

If the light is on you will get a code. You will have to find a Eaton/Bendix manual with codes.

Last time I had a problem it was the front drivers side sensor. I pulled it out, clean it and put it all the way back in, drove it, and the light went out.
