my friend, who is not computer literate asked me to see if i can locate a part for him.he has a 2006 monaco on a roadmaster chassis. he took his coach to freightliner in phoenix. his complaint was the abs light stays on.
they diagnosed it as the left front steer axle solenoid. but could not supply a part. they had no idea where to get it. they suggested maybe monaco.
on the internet, i found an eaton manual that shows the rear module in an assembly, but the front as a single valve.
on this coach, the front abs modulator assembly, appears similar to the rear modulator valve assembly.
it has two modulator valves,with a standard relay valve in the middle. if anyone has any information, please let me know. pfmaddox@att.net or 602-549-3638

By saying "left front solenoid" I want to think they were referring to the actual air/electric valve that each wheel has. This would definitely be a chassis builder item as opposed to Monaco (the body builder).

It might be a Bendix #5011740. I purchased one from Monaco who orders it from Bendix. Mine was about $387.67. deSanford

Call and check with this group. Ask friend if they did a reset on the board or if they pulled the trouble codes. There is a ton of info on the ABS light on here on this site. Use the search function if you have not already done so. I would be concerned that a freightliner shop couldn't get that part.

thanks for the replies. this problem developed when he had new tires put on the front. the module turns out to be a bendix part like desanford said. the owner talked to bendix, who doesnt believe this is the problem, and monaco who does, so he is taking it coberg to to have it repaired. he was going to grants pass anyway.again, thanks to all.

This may be a bit long so be patient and maybe some of it will help.

I have an 08 Endeavor and it has acted up on occasion too. This is a common issue but on a recent trip mine came on and stayed on. Shutting the engine off and on did not help as in the past. Lots of folks mention cleaning the sensors but there is no way to clean the ones on my mh. The following information is copied from previous threads and I keep a copy to quote from.
"In the front run bay, there is a relay with a reset button specifically for the purposes of resetting it--somehow--check owner's manual or call Monaco tech support...I bet with all the disconnecting you did, you might have thrown the relay for a loop.
__________________
Also try turning off batteries. You might need to drive over 5 mph to get them to reset."
My front run bay does not have a reset button. I actually looked for one yesterday and did not find one. Turning off the batteries might clear it for awhile.
Here is how I think I resolved mine. I am an ET with 40 yrs in the vehicle electronics installation business. Not abs or such but radios etc. Cop car build ups and fire trucks so some excellent experience.
Mine too was intermittent and weather sometimes seemed to be the cause but a particular bump I go over seemed to trigger it on more than one occasion. Once the light is on the cruise control does not lock on my unit.
As I was trying to figure out how to remove the sensors I discovered they have a long pigtail going to a plug. Research showed me that they should have about 1700 ohms resistance. Following the wire to the plug the first one over the rear axel showed signs of water corrosion on the pins. I cleaned all four sensors and checked their resistance. Using some WD 40 on each connector before reconnecting them should help keep the water out. I only found one that was really suspect and a second that showed only slight signs of water. Since doing this I have not had an issue. We just took a 300 mile trip and it worked perfectly. I am confident this solved my problem.
Except they came on again on a shorter trip after hitting that special bump on hwy 20.
--------------------------------------------------------------------------------------------------------------------------------
For a long time I was afraid to pull the front sensors out because they seemed very very tight. I finally gave one a twist and it moved. It came out without much effort after that. It was very greasy and had a large clump of grease and grime on the end of the left front one. The lump was about 1/8 inch thick. This definitely could be the issue. After cleaning them I test drove a short distance and no issues. The sensors do not go in as far as you might think. There is quite a bit still sticking out once inserted. There is a copper/brass looking insert the sensor sits in. Mine seemed to be in pretty good shape but that clump of grease on the one was significant.

My ABS light comes on all the time when I start up. The codes are 0-0 shock wand no error. I just reset it, and go. I had it checked out by Josam in Orlando. There's no problem they can find. I even changed the ABS board. So u just reset it before I drive and it stays off the entire leg.
