Most likely a wheel speed sensor issue. I've replaced all four of ours, cleaned and calibrated the air gap multiple times. ABS light still comes on occasionally, then goes out without storing any trouble codes. It seems to have a mind of its own, but the brakes work fine. One of those little quirks I've learned to live with...
I've never come close to locking up the coach brakes anyhow.

Mine comes on about every other time I drive it, while turning around in the yard preparing to leave. I shut the motor off, restart it, and it stays off afterwards.

I have had our coach for over 12 years and have the same issues.I have come to a point that the ABS light is a lost cause.

Yep, same here. Or, we'll stop for a bit, re start and it comes on until the next key cycle. No rhyme or reason. I'd say it's on about 30% of the time, with no flash codes ever stored since replacing all the wheel speed sensors. Not an uncommon occurrence according to other Alpine owners.
Funny story...the wife asked what that light on the dash meant. I told her it stood for "All Baggage Secure reminder".
She looked around and noticed we forgot to latch the pocket doors and the Mr Coffee was still on the counter. By the time she sat back down the light was out. No, I haven't told her lol.

Pretty easy to R&R the wheel speed sensors-- all you need is a pair of pliers to pull them, clean and reinsert until they contact the tone ring. DONE. Drive a short distance to clear the code.


Might it be something else-- sure. But start with the "free and easy".

It was on when I test drove ours. One of the wheel sensors was replaced. The light has not appeared in over 8,000 miles -- hopefully I didn't just jinx myself.

Mine will come on when first starting the engine but goes out after driving for a few seconds. And, if I park for a few minutes with the engine running it may come on. I either ignore it or turn the engine off and back on the drive.

That is exactly how my coach operates.I have thought of pulling that little bulb out many times.

I agree with Wolfe! Cleaning and resetting the sensors is relatively easy. The real need for abs is on slippery surfaces.. Snow, wet roads and when hydroplaning. With the light on, if it is just a sensor reading, you loose the ABS feature at that particular wheel location. Rarely used, but when needed, it can be priceless. I would certainly try the easy fix. On road tractors the most common repair on ABS is setting the sensor gap to toner ring clearance. Second is poor electrical connections in the ABS wiring system.

Trouble shooting the ABS

Attached are a couple WABCO articles (truncated because of file size limitations - available on the internet with a Meritor - WABCO ABS search) that may help you decipher the blink codes the ABS computer transmits to the dash trouble lite, and the documentation on replacing the wheel speed sensors if that turns out to be the faulted component. Depending on your coach configuration, the front speed sensor replacement can be a big job since it may entail removing at least one of the weight balancing bricks (as in my 2006 34' Alpine) to gain access to the speed sensor pigtail connector inside the lower frame rail adjacent to the fuel tank, and just forward of the suspension airbag on each side. Blink code diagnosis is accomplished by operation of the ABS test switch adjacent to the engine diagnosis port in the passenger side, forward electronics bay under the VMM suite.

Add me to the list--I had the same/similar ABS issues with my 2003 Alpine. No rhyme nor reason to when the light came on or when it went off. Was never able to "activate" the flashing light code feature on my 03. Several old posts from "Green Machine" on this forum suggested that this function wasnt available on all models of Wabco ABS, so you needed their proprietary software and interface plug-in to identify and clear codes???
