Happy to report that this issue is now RESOLVED! Once I found that I had a Gen 4/5 Bendix system I was able to find the key to the blink codes and discovered that the problem was the right rear speed sensor position. Went back to the shop that did the brake job and the owner was insistent that they had checked that but agreed to check again and discovered that was indeed the problem. Pushed the sensor into position and went for a drive. A block down the road the light went out and has not returned. I really appreciate everyone's help here! If any of you ever have this problem this data sheet is invaluable: Gen 4:5BendixABS Data.pdf

Ivan K - I wasn't aware that there were other modes to enter by pushing the button more than once. Three local shops have all plugged scanners in. One did not have the correct software, the others did but the scan tool reported "No Active Faults". Looks like I've got me a gremlin!

Took the coach for a ride yesterday and unfortunately, the ABS light came back on. Did the blink test and it flashes 16 times, short pause, then 5 times. Then it blinks different sequences and after about 3 or 4 different ones the light will go out until you take off again. After the last stop before heading home I performed another blink test. Lo and behold, different series of blinks this time and the ABS light stayed off but the ATC light would not extinguish! Seems that no one in this town knows anything about what's going on! The brake job alone was over $3000 and they assure me that they've checked all the wires and sensor positions. Now I don't know if I can trust the coach for a trip! Any suggestions would be helpful.

Disabling the ABS would be my last possible option. The system went through it's checks, extinguished the light, and now blinks 1-1 like it should when there are no faults to correct. Still haven't had the time to take 'er out for a ride to make sure the light doesn't come back on but will update when I do. Thanks for the feedback everyone! This board is a great resource thanks to y'all!

😂 "Little ball thingy" is a perfect description! I looked right at it and never thought it to be a button because it was right next to a bolt that looked almost the same (I sent my wife under there and she spotted it right away). I went through the prescribed sequence and after flashing different codes for a while the ABS light went out and stayed out. Now to drive it and make sure it doesn't come back on. Thanks all for the help! I'll update once I've had a chance to test drive....probably tomorrow.

Thanx for the cheat sheet! I'll go check for the test button in the electrical bay.

I believe it's a Meritor system and yes, it's a diesel. I'll take the coach for a ride later to see if lifting the foot pedal is the answer. I had that issue on a Tahoe once but it didn't impact the ABS, only the cruise, but at this point I'm willing to try anything!

Now I'm really confused! I went to the coach to do the blink because I wanted to know what the code was before I tried to find a decipher key. My addendum says the test button is on a Systems Diagnostic Center left of the steering column below the dash. There's nothing over there except a bunch of wires and the 9-pin ECM port. Does anyone have any idea where Monaco may have moved the test button to?

Yep - I discovered the blink code addendum right after I posted this and immediately called the mechanic. He tried this but couldn't find anywhere to tell him what the code was telling him. The fault must still be present because that doesn't turn off the ABS lamp. Do you know where I can find an explanation of the blink codes?

Just had new rotors and pads installed but now the ABS dash light is lit and won't go out and cruise control doesn't work (to be honest, the cruise control was hit or miss to begin with). The shop that did the brake job didn't have the software to read the code so I went to another who scanned and got the result "No Active Faults" and "No Inactive Faults". Ohmed all the speed sensors and they test out fine. The shop that scanned the computer claimed that there is no need for chassis-specific (Roadmaster) software because the braking system is its own software. I cannot find anywhere if this is true or not and I hate taking the expert's word for it. Anyone else have this problem and if so, what was the fix? Thanx in advance!
