ABS Light

Thanks for the info manual, allway nice to have.

I have a 2000 HR Ambassador. On mine, the procedure to read out the ABS codes is to remove the ABS bulb from the instrument panel, then turn the key to the “ON” position, reinstall the ABS bulb and read the blink codes from the ABS bulb. There is about a 1.5 second delay between the first code digit and the second, then a about a 4.5 second delay before the code is repeated (or a second code stored).
I was able to get, online, a manual that explained the codes. The manual I got is available at www.meritorwabco.com/MeritorWABCO_document/mm39.pdf.
This manual is for my MH, so you might want to check which manual is applicable to your MH.
Hope this helps identify your problem.

You'll need someone with a better code reader capable of interfacing with the ABS controller to find the problem. Usually, as most posts have stated, a wheel sensor has failed but which one since there are three or maybe four. Not difficult to replace but you will need a bit of physical flexibility to reach the sensors and associated connectors.

Give Freightliner (assuming the they are the chassis builder) a call so they can direct you to a local chassis service center with the capabilities of testing the system. They might charge you a bit to run the test but will save you lots of time, effort and frustration swapping out good sensors.

I'll second what C-Leigh said. Fixed mine. Should return a code to tell you that's the issue. Five minute job to replace it.

actually, at the risk of igniting a huge debate, I prefer to NOT have ABS.. I'm old enough that I actually like to have control of my vehicle.....as my son has said "the more they try to make the world idiot proof, the more idiots they create" To me, ABS reduces my sense of control & awareness of my vehicle... in my car I have had ABS activate... not a worse feeling for a driver!!!

Ours light has been on 4 yrs now. Needed special appointment at truck/brake shop as dealer couldn't work on the chassis. Stated sensor probably just loose. We haven't bothered with it and we are fine with no abs. Up north they are advertised as helping on slippery wet surfaces which we do not drive on. Drove for many many years before ABS was ever invented , and can continue to do so.

When was the last time your brakes were adjusted? Even with auto slack adjusters, which you should have, you have to check them. An out of adjustment slack adjuster can also trigger the ABS light. I have had it happen to me.

When the ABS light stays on, you DO NOT have ABS. Your brakes will still work, but the anti-lock feature is off. IN other words, your wheels can lock up and skid.

my ABS light is always on in my Tradewinds... I asked a truck fleet mechanic I know how to fix....he said a properly placed 3/4" x 3/4" piece of black electrical tape will solve the problem.......... my braking is fine, no issues..

If you had a F53 Ford, all you would need to do is replace the censor on the top of the rear diff to cure the ABS light problem.

Mine would come on after a short distance driving, replaced that 12 dollar censor & light not came on since.
