My truck just started giving that same code U0001 this week. It has done it 4 times so far. I am looking for some imput too on this
I know, I'm in the 3rd Gen Section - I've been dealing with this code for about a year and half (maybe longer), along with U0121 and U0141. I didn't have a problem for over 6 months, then I helped someone out with similar codes and these all popped up again the very next day. There should be a NHTSA safety recall to make Chrysler fix this problem without us having to pay for it. When these codes pop up, I lose the Engine Brake and cruise control, though they can be turned back on without clearing the codes. The instrument cluster goes haywire and a couple days ago I noticed the trailer brake controller was malfunctioning (CF I believe was listed on the display and the slider wouldn't do anything). Imagine if you were pulling a trailer, down a mountain and you lost the use of your EB and trailer brakes - sounds like something that NHTSA needs to get involved with. I am out of warranty, but we shouldn't have to pay to fix their crap that they won't let companies like Drew Tech incorporate dealer level diagnostics into their equipment so we can fix it ourselves.
I have found though that the only time this seems to occur is during the hot months here in Las Vegas. I didn't have a single issue during the cold months.
I know it has been a long time since this has been talked about but did you ever get an actual fix on this issue? Thanks
No, I haven't. It's tempered itself way down over the years. I'll get a U0141 every now and then. A U0100 pops up once in a blue moon, which I believe is what keeps the truck from starting - this momentarily happened in the summer of 2019, but woke up after a few minutes. I'm 99% certain it's wiring at this point or maybe a cold solder joint inside the TIPM, but I haven't had the desire to even look into it much further as the years went by. If I'm driving when it happens, I just go into the Black Maxx, reset the codes and keep on trucking. Fortunately, it has never happened while pulling my toy hauler or any trailer for that matter.I know it has been a long time since this has been talked about but did you ever get an actual fix on this issue?
