Re: Cruise control not working Reply #25 – October 09, 2022, 02:38:18 am So far no luck tracking down this problem, was wondering about what physically operates the throttle body. Could this be mechanical and not electrical? Quote Selected

Re: Cruise control not working Reply #27 – October 09, 2022, 07:33:06 pm I am pretty sure that you need to have Cummins hook up a computer to it and that will tell you what the problem is. Quote Selected 1 Likes

I called Cummins and he said all they can do is tell me if cruise has been activated or not if I bring it in, but can't trouble shoot any issues... but maybe he didn't know what he was talking about. 🤷♂️ Quote Selected
Re: Cruise control not working Reply #29 – October 10, 2022, 08:21:07 pm If you haven't had Cummins flash the firmware in the ECU with latest update, I recommend you get it done. A Cummins Coach Care location can do it in a couple hours...takes several cycles if it's never been done. Cost me $150 if I recall. It will change the cruise control prediction curve and a cool feature is that it allows recall of last speed even after shut down and restart. The engine just seemed more responsive after the flash.

Re: Cruise control not working Reply #30 – December 28, 2022, 02:53:34 am Still slowly trying to trouble shoot cruise...shot another video showing what's going on in Bluefire app.I havent taken it to Cummins yet because I keep getting told that the problem is with the OEM side and all Cummins can tell me is if cruise is activated or not in the ECM, which I know it is 🤷Video:Microsoft services Quote Selected

Re: Cruise control not working Reply #32 – April 30, 2024, 02:45:26 pm Need to check where you have the retard set at. If the retard is on when the coach starts to coast it will shut off the cruise.. Quote Selected 1 Likes

I had cleaned the steering wheel contacts early on but it didn't help, then after many months of trouble shooting cleaned them again and it seemed to help, though that may have been coincidental. The gold disc plates that the contacts touch on the steering wheel seem to be heavily worn so I wonder if that's the culprit....and how hard it would be to replace them if they are available.

Re: Cruise control not working Reply #34 – April 30, 2024, 08:05:36 pm I recently posted my challenge in finding parts for my smart wheel. Smart Wheel IssuesSeveral functions had "died", most related to cruise and after replacing the control module I searched and found a NOS complete wheel on eBay. I was convinced that my problem was related to the button modules but the seller of the NOS wheel also sent the Douglas Autotec HB2P service kit which had the collar, springs, ring and contacts. I replaced everything...the button modules, the collar, spring and contacts and everything now works perfectly.At the time another seller had the parts you're looking for:Douglas Autotech Horn Brush Kit DUG HB2 B115x16 | eBayYou might try contacting him to see if he has more or to find out where he got them.Douglas Autotec was acquired byJ TEKT Column Systems North America Corporation effective April 1st, 2023. They're still located in Bronson, MI and their phone number is Ph: (517) 369-2315.This also might work???NEW Douglas Autotech Horn Brush Kit DUG HB01 | eBayEntire steering columns also show up on Ebay so keep your eyes peeled.I encourage everyone who has these model coaches to look for parts NOW as they're going to be increasing hard to find.

If I were to source one of the horn brush kits, do I have to remove the whole steering column to replace? Quote Selected
Re: Cruise control not working Reply #36 – May 01, 2024, 06:48:04 am No. Paul Yasbeck did our work but from my understanding it's accessible after wheel is taken off. Others here can probably confirm. Be worth a call to FOT and MOT as well on the chances they have one. Quote Selected
Re: Cruise control not working Reply #37 – May 01, 2024, 11:03:57 am I'm short on time so I haven't re read all the post to see if this has been mentioned. On my coach there are two brake light electric valves in the first bay drivers side and one of those being bad caused my cruise issues. My coach is manual as in no ecm so obviously there are differences. Quote Selected 2 Likes
Re: Cruise control not working Reply #38 – November 04, 2024, 02:26:54 am Wanted to follow up on my cruise control issue. I think I may have finally fixed it. I'm going to post this resolution in 2 posts since there was discussion about this in both.I had previously ruled out the steering wheel "clock spring" thingy, though technically mine is not a clock spring, it's a "dual contact horn brush".During my trouble shooting I cleaned the brass rings with contact cleaner with little success but had noticed that some of the ring was wore down to a different color. I assumed that since the two contact pins were still contacting the rings that this wasn't the problem, along with the fact that the intermittent problem didn't seam to coincide with turning the steering wheel (tilt and telescoping also). Well was I sadly mistaken.I was going to change out my brake switches but felt like that wasn't the problem so I tackled the task of tracking down the horn brush. Foretravel didn't have the correct part number so I eventually found it from Jtekt. I think they bought out the original manufacturer of these (Autotec), but not sure. There are 2 part numbers (the part# for mine is 1900041) and the only difference is the length of the "gap hider", the round piece that's below the steering wheel. Luckily I talked to a knowledgeable man at Jtekt and he confirmed the correct part number for my application. (I just had to measure the 'gap hider') I actually had to call Foretravel and give them the correct part number so they could order it because I couldn't order direct from Jtekt. It was $250 with shipping but well worth my cruise control working.I'm on 2 trips with not one mishap with the CC so hopefully I didn't jinx myself by celebrating too early. We'll find out Thursday when we head to Fort Bragg.Hopefully if someone in the future has similar symptoms they will see this post and it will save them hours of pain and anguish tracking this down.I attached the installation instructions I recieved with the part, not a very hard job just need to follow a few key operations.After reading through this post again I should have listened to Floridarandy sooner. He mentioned tracking down the Horn Brush...it's just that the cruise not working was so random and intermittent I didn't think it was that was the problem. 🤷♂️🤦♂️ Quote Selected 7 Likes
