They said that they couldn't re-flash it, that it keep taking them to the beginning and its because of the p1400 code...
Then how did he manage to flash it in the first place then? sounds like an excuse.....This is why I hate most dealerships/service depts....

So question, have you at any time swapped in an unlocked pcm and loaded a tune? My guess is yes, and you swapped back to the stock pcm before bringing vehicle in. P1400 means unauthorized software was loaded at some point. The code is hidden so won't come up on regular scanners. It's stored in the bcm, so the dealer will know you did just what I am asking. As soon as the vehicle is scanned at the dealer, that info is sent direct to the mother ship. The dealer then has to prove to the company that any non stock pcm software was authorized. I went through this year's back because of a Diablosport tune that they said was undetectable, but or course was, and they never stood behind it.

This is a repost from another thread, hopping that someone may be able to help. Hello everyone, so I went to the dealer for a battery issue on my 2021 durango srt, I went to turn and the car lost power and basically shut down while driving. They first asked me if I had a tune on your PCM since the system accused the code P1400, I said no but anyway isn't the pcm locked? Yea but people find a way, I'm like the pcm in the car right now has no tune right, but if it did what does this have to do with the battery? Well nothing, so ok then, I guess you trying to mention this for the potential battery warranty claim i'm about to put in for ? Anyway it was a ground wire issue, and since you where here we had a recall for your car so we installed the latest Uconnect software, i'm like I did that already I got the usb key in the mail, well it didn't take it I guess, i'm like ok then. Anyway I get in my car and nothing is the same I assumed all got reset I guess? Well little did I know that they I guess they installed the r/t update and now I'm on the R/T dashboard and missing stuff on my dash, called and gone for the day! Called next day saying i'm on my way, and the answer was we too busy can you come tomorrow, ok then. So today I went in, bottom line they can't reflash it, because I have a code for a tuned pcm that is not tuned, I explained that some of my security features that were available on my SRT are not available and I don't feel safe driving it. The manager comes by and tries to speak to me like I'm ignorant and no nothing about cars of software or electronics," someone did something the exhaust you have is after market and they need to tune the pc to make it work and bla bla bla...Well there goes the neighborhood, im like what did you say??? first my exhaust is certified by Mopar it's a gthaus meisterschaft and there's no need to do any software updates or tunes, so no warranty voids you should know that sir, second you claim that you cant refresh the car because the code P1400 is present correct? The code happened at 5000 miles I have 19000 miles so unless in the last 2 days I did 14000 miles you couldn't have been able to flash it 2 days ago right? Is the PCM flashed? NO is the PCM the original one from when I got the car? Yes, so wtf are you talking about??? Well you have to call dodge and explain, I am at dodge right now and how am I going to explain something that doesn't make sense, what next explain flat earth? What are they going to do that you cant? can you clear the code? No. So how can THEY clear it?? You fuck up my car and i'm responsible to find a fix for it??? Anyway no idea if someone dealt with this or what to do here? Is there a way to reset the cluster? View attachment 123579 View attachment 123578

rayjj lets say I did what would that have to do with the mistake they made? The code prevents the icp from being flashed they said, but they did. My issue is that they used the code (that they might have seen several times while visiting the dealer) as an excuse that this caused of the issue. They claimed that they didn't flash the ice but according to dodge they did, to fix the gas gauge misreading the levels. Waiting for dodge to get back to me.:cautious:

I am far from an expert here, but it is probably unlikely a software update for an RT could be installed on an SRT, I would be pretty sure update go by VIN. The whole mileage discrepancy you mentioned probably is because of the PCM swap. Just remember, anything you do as far as PCM goes the dealer can see. I had same issue, they knew everything that I did as far as a tune goes. Many times when a battery dies, or the battery is disconnected, you will get generic screens that pop back up on your radio initially. I remember once seeing a Chrysler logo pop up on my radio after swapping PCMs. Sounds to me like they are basically telling you they see all your aftermarket performance stuff and dont wanna touch the vehicle. Price you pay for modding. I learned the hard way too. Very unlikely SRT is going to do a thing for you since you are tuned.

The only way to correct the gas gauge calibration is to flash the BCM. That's not something done with the IPC module.

The BCM will report a P1400 if you ever had an unlocked PCM installed, and that code cannot be reset without replacement of the BCM. The BCM can still be programmed with that code present, so saying they cannot reprogram is not true.

I have been a Mopar person since I was a little kid. We always had the, ('58 Dodge D500, '60 Matadore, '64 Imperial, my '69 Super Bee, sister's '69 Van, '70 New Yorker, 2002 Intrepid, 2011 and 2013 Hemi Durango Citidels). In 1976 I started selling cars at a Chrysler dealership. I've been a garage mechanic fixing and racing since my mid teens so selling cars for 31 years I wasn't your average useless salesman. In that 31 years I sold Chrysler products Bout 80% of the time, even being a Dodge truck manager.

I learned very early in my sales years, Chrysler products don't have any more problems than other American cars. This problem is when they brake the service departments CAN'T FIX THEM PROPERLY, the first, second or often the 3rd time. What you're suffering from is typical sloppy (shitty) Mopar factory service. When I bought my '11 Durango I popped for the Chrysler 'Ultimate' (Forever) warranty. The dealer I was a truck manager and (only) product specialist for wanted to Charge me for repairs covered by the warranty. And often took 2, 3 or 4 trips to correct them (my driver's seat heater and radio Uconnect for only w as an example). Another problem was when they serviced the Durango they'd Slam the hood down which eventually broke the wiring in the hood latch which stopped it from remote starting. They wanted to charge me over $400 for the water pump under the extended warranty (a $100 deductible). Eventually a retired parts manager steered me toward another Chrysler/Dodge store 24 miles away that does decent work.

Bottom line; Mopar service tends to SUCK. Talk to other stores. They all have your SRT's records so they will know what's going on. Good luck

Welp, it is messed up that they won't correct the ipc, but you now are not denying swapping pcm. Unfortunately, you don't have a leg to stand on. That code, is warranty Gone.
Bro why you always so grim?

My pcm is not tuned they agreed with that.

I don't know then....

yep, next week I'm going to a used Mopar tech that I meet at the local cafe, started a talk since he had the Mopar shirt on and he said it is possible to reflash it, ill let you know how it goes.

Was it worth losing your warranty for the tune? Just curious.

Wait, did he admint he has a tune cause I did not see that? Or are we assuming Dodge and their dealer is infallable from making a mistake? If you recall my dealer tech (punk kid) told me the medium heat setting is working becuse there is no logic in the system, it is on or off. ROTFLMAO

He never denied the tune, so I'm taking that as he's tuned. I'm telling you, that code DOES NOT just magically appear.

Tuned or not doesn't excuse the dealer for mucking up the reflash. Dollar to donut they knew what was going on, flashed it wrong, and then want to charge for a new pcm to “fix” it.

Possible the update went bad because of the PO1400 code stored in the BCM? Possible thats why they asked if tuned, and denying it was is all adding to the problem? I get not wanting to tell a dealer you are (or another PCM) was tuned, but just maybe that is all part of the issue? Pay to play. I dont think this is gonna go the way the OP wants (hope it does work out for ya honestly).

P1400 isn't used for anything. It's a flag, and nothing else.

If it's set, there is a flag for "After Market ECM Detected: Yes". That's all.
