Got my updated jib back For the 2017 Cummins 450 with the 500k green twist on plug and all the guages on the Vmspc are working ok. But my problem is every few minutes the dash warning lights go crazy. ABS, Check engine and other lights come on and off.
Hello RJ We've tried to reproduce this on a 2017 that rolled through today. It didn't exhibit this oddity--however, there's about 4 different coaches (Tiffins and a Newmar) which do much as yours. We're comparing some raw-logs just now to see if there's some pattern or discernable error which we can work with. Is this about every 4 minutes...or 5? Does your PC continue to otherwise work normally or is it affected also? Art //
Art, I really didn't time it, but it seems to be about 5 min. will time it tomorrow. When Idling I just get the ABS light coming on for about a few seconds then off. The PC will show error codes which i sent you. I haven't ran the coach on the road, just that one trip when the dash lights were really acting up. The pc seemed to be fine if I remember right. but I pulled over and disconnected the jib and all was normal again. Will be taking a long trip starting June 7th. and will try it again Ralph
Hello Ralph We've identified that the firmware is contributing to the problem. It'll need to come back at some point to be updated. However, that said, we're still working out a consistent fix. This problem isn't seen on every 2017 which has made it more difficult to nail down. Stay tuned Art //
Ok Art I'll wait for it. Let me know when to send it back for an update. Thanks, Ralph
I have a similar problem occurring on my new Tiffin Phaeton with an ISL9 380 engine. My ABS light and MIL will intermittently come on and off. I also get the following message on my LBCU screen: TRANS COM FAIL In addition the Gear Selected and the Odometer functions don't display any data. Is there a list that I should be added to so that I'm notified when the update is available?
Add me to the list. I have a new 2017 Allegro Bus, 450 ISL. Ever since I plugged it in two days ago, my ABS light blinks on and a beep tone sounds. It has happened the last 2 driving days, sounding sometimes every 60-90 seconds, and then may fall silent for 20 minutes. Often occurring at the same time, the cruise control will kick off, and the speedo will drop to zero. Usually towards the end of the driving day, I get a amber MIL light that stays on. Today I took the rig to a Cummins dealer and they plugged it in to the diagnostic computer. At first the software wouldn't run as the info from the ECM appeared corrupted. I went and unplugged the VMSpc from under the dash, and cycled the ignition key. Their program immediately hooked up and showed about 40 instances of fault codes, mostly all different. He cleared them, and we rechecked the ECM again. All clear. I left it unplugged, drove about another hour, no ABS lights, or codes. The two codes that kept getting set were ECM SPN 191 FMI 9, and ECM SPN 84 FMI 9. Both being communications errors. Also the VMSpc program is not performing as expected. The "gear selected" digit does not display in the gauge readout. The "current gear" displays and changes along with the trans. The odometers and tank minders still don't work as well.
Hello Marty It took a while, but we identified a bug on 2017 Freightliner chassis which presents itself when we plug in. A firmware fix has been released which works around that. Only a couple samples back so far--but good so far. I'm wondering if its the same bug--Is that Allegro on the same type or their own home-brew? If you ship us the Jib, we'll update the firmware and return on our dime. Also, be sure to check out the new v4.0.6 software. You may use the Layouts from the v4.0.4 and above. Give a call and I'll get you an RMA number to get this started. cheers Art //
Will do Art, thanks.
Art, Is there a fix for this yet and should I send in the jib for a firmware update? Ralph
