2014 E350 Command REbooting
Recently the Command / Computer / Radio in my wife's 2014 E350 started randomly rebooting or failing to come on at all. It happened while I was out of town, so of course, she took it to the dealer and spent $200 for them to say "We tried everything and you need a new system at a cost of $4,400."
Googling around, I've seen several videos and articles that describe using a fiber loop adapter to systematically "remove" various components or modules from the MOST Network; modules like the Sirrus receiver, nav unit, voice control module, etc. In THIS video the fellow uses a fiber loop adapter to "remove" the potentially failed module from the MOST Network, but in THIS video, the guy simply unplugs it.
The modules that I have heard of people having success "removing" from the network are; the CD changer, the amplifier, the Voice Control Module, the satellite radio receiver. I'd have to believe there may be others. I've also read that of these modules, with the amplifier, that module must be replaced, you can't just remove that one from the MOST network.
Is there any definitive guide, or video or Wiki or anything regarding this issue, troubleshooting procedures, and fixes? I really can't afford to replace this thing at $4,400 and my wife can't survive her commute without a radio. Kind of a bummer that her 2014 vehicle with <100k miles has this expensive and problematic of an issue. Hopefully I can resolve it.
Thanks,
Chris




Made an appointment and re-installed the radio just so the dealer wouldn't give me a hard time, and discovered that it now worked as new. No need to take it to the dealer, just pull it and let it sit for a period of time. It is an easy removal....
Your NTG was in a severe boot-loop, rebooting the car itself didn't not help NTG.
After pulling the unit out for some time and reinstalling it, now it works well.
This is good karma! I am guessing your unit needed a sort of vacation... likely a marginal 16Volts capacitor gone bad in a hurry working under 14.9V + ripples.
This Mitsubishi head unit internals remains a mystery to me, safely hidden behind countless screws

Repairs between $2500 and $4000 are a good encouragement to spend a couple hours to fix the built-in defect.

The boot loop, as far as I understand, is the Windows CE/XX failing to boot. Similar to Windows 10 boot loop I guess

I am still trying to figure out the intermittent rebooting problem. Can you expand on your reply? Im an old electronics tech so you can speak electronic to me.
Thanks

There is an engineered failure in that Mitsubishi unit that materialize regularly. It's Not a random one in a million type of failure...
Based on what we've seen on this chassis we can make educated guesses until we find proofs.
It could be the amazin' 16V caps,
could be oxidized solderless pins,
could be poor painted GND,
could be failed boot enumerations,
....
Without any clue, a schematic or troubleshooting procedure, we are helplessly trying to repair this $4000 rat-trap.
I know very little about this mystery-box. Mine boots and plays sound surprisingly much faster since I have resoldered my CAN-B modules.
So I can confirm that CAN plays a role in NTG boot speed.
Perhaps there's a timeout that causes unit to boot-loop searching for peripherals. I have not dealt at all with the MOST fiber ring. I think MOST is fine even though we know there is an enumeration of fiber devices.

Our incentive is we can expect a simple repair once it's all figured out.
