ABS light on

[Melorene]

My abs light keeps coming on..took it to Freightliner and there computer downloaded 3 faults, 255 were under the heading of Retarder-Open, The tech could not find a relay to check to see if it may be causing the problem. I have no wiring information. We did see the fuse panel on the back of the battery compartment but not sure what is causing the problem. Any ideas?

We have an 06 coach and almost from the day it was born our ABS light has been on. We have had it at the factory, Cummins and several major RV service centers and nobody has figured out how to fix it. I have been assured that the ABS is working, so now I have learned to ignore it.

My '04 coach had the light come on for the first time (and stayed on) a few months ago, and is currently at a repair shop to diagnose it. If they find the cause, I will post it.

I had the same problem and Mark from WRV, (Yes the same Mark that is under contract to ACA) helped me fix it. In the fuse panel behind the batteries there are some black plug-in relays. one of these relays is for a Jake brake ABS cut-out. Remove the relay and bend the pins inward slightly and plug back in. Worked for me. If you have further questions I would call Mark. His name and number are posted on the ACA Web site

Wow, that sounds exciting! I will try it also. I would love to have that light go away.

There is a fuse panel behind the batteries???? On my 03??? or is this a "later model" thing?

If what's happening is the relay contacts are not contacting, then a bad relay would do the same. So if bending won't expunge the light, try a new relay (take the old one to NAPA or AutoZone & they can match it). Worst case- you have a spare relay.

Mike- its an 04+ thing. Your fuses are in the maintenance bay aft of the batt's.

Hey E-Mike congrats on your 1500th post.

Was hoping nobody would notice I'm getting older.

I reached for the relay in the fuse panel, hoping it is the right one and whamo, it almost fell out in my hand. Bent the contacts inward and now nice and tight in the socket..won't know if it did the job or if it was the right one til the end of the month when we head to Guaranty in Oregon for the appointment we have to have it fixed along with a couple minor other items, then onto Alpenfest in Canyonville, Or. =M
