I know this is an old thread but still....
I have a 2018 charger scat pack with codes P1400 and U140e anyone here can help me what should I do.
I have checked all the wirings and also checked for the bent pins in the PCM everything is ok but my ABS light and traction light is on.

did just start my own post and found this thread here: I got my 2018 Challenger also tuned with a VVT camshaft etc and now I get the error codes U0100, U140E and C2202 like posted above. The engine justs stops when in N or P after some seconds and the torque-meter in my dashboard shows 1300nM while the engine is not running. The engine then wont start again till I disconnect the battery for some minutes. Driving or going reverse is no problem. Any abs lights or engine lights dont light up. Can anyone help?

from reading past replies this only seems to happen to remapped engines, i know you have a camshaft but try putting the original tune back on it and then putting the new one on again

U0100-00-Lost Communication With ECM/PCM
U140E-00-Implausible Vehicle Configuration Data Received
C2202-00-Original VIN Mismatch / Missing

What are you using, HP tuners? If so, are you cutting and pasting from a tune that came from another vehicle?

 

[v4rg]

I did not tune it myself, the car was tuned by a wll known german car specialist. I would have to ask him what he used

The VIN mismatch is what I find concerning as that is not usually a problem with PCMs that have the correct VIN written.

that sure is strange, but it seems to be the same error that was posted on page 1 by someone else. Those error codes are the same I have. Would be interesting if someone could confirm if rewrite all settings would be helpful.

When I had Arrington tuning my manual RT (apparently used Petty's Garage for email tuning at the time) they sent me a baseline tune that was setup for an automatic as the P/N RPM table was set to 3000rpm (IIRC). Would be nice if these tuners are using HP tuners so one can compare stock and modified tune to see what changes were implemented. Would also be nice if folks reported back on whether they resolved their problem or not.

Seems like the engine runs sometimes in N and P and sometimes doesn't. I recorded a clip directly after starting the cold engine and it did run fine. Today the same behaviour before driving, after coming back home and switching to P before turning the engine off, the engine stopped running and again showing 1200nM @ torquemeter.

 

[v4rg]

so, after talking to a german Dodge-technician we got the idea that my problem occurs in combination of my AlfaOBD-settings (I made a long time ago) and maybe the settings that were applied to the pcm by the tuner. Unfortunately, I don't have my old backup from alfaOBD anymore. I already tried to revert the settings I made, but still no luck.

Can anyone provide me an OEM alfaobd-file for my Challenger or knows where to get one?

There should be several BCM logs in this thread although I don't think that is your issue as I have made extensive changes to my BCM and PCM tune with no such DTC ever appearing.

[v4rg]

although I don't think that is your issue

at the moment I am willing to try almost everything to get rid of that malfuction

can I use your 2015 Challenger with a newer Challenger? Just upload the file and that's it? At least model year and some of the equipped parts can be different.

+2018 have a different config layout and the logs are not files you upload but instead are text versions of the configuration that you compare using software like winmerge to identify changes. You then need to determine if the change is appropriate for your model. What changes have you made to your BCM...fog lights, chassis type...etc.?

 

[v4rg]

I just wanted to have the performance pages and was testing some values.
Changes were made for:
Vehicle is SRT
Special Package 1&2
Performance Pages present
Global windows down
STP

All of the above was changed back to default yesterday, except PP and Global windows down. The vehicle still stops the engine when in N or P.

I monitored the CAN bus for torque and saw values above 5000nM when in N, then those were falling down, going back up over 5000nM and then the engine shuts down.

 

[ChallyTatum]

Those BCM changes should not cause any issues with the PCM losing bus coms. Have you tried loading the stock PCM tune to see if the problem persists? BTW has the TCM also been modified?

 

[v4rg]

not yet, I will have to change some values of the stock tune so it fits my car.

As far as I know the TCM wasn't modified

 

[Jsal13]

Any update inhave the same error codes

Has anyone solved the codes ?

Welcome

It’s not that simple. You can’t just say “these are the codes I have, what is the fix?” Unless maybe it’s a stock, unmodified car, then the fix would be to find the wires that the rats chewed up.

With an almost 20 year old, high mileage vehicle like that it is highly likely the ABS module has failed. The C2100 happens when the ABS detects the system voltage is below 7.5V. If the battery was bad then other modules would have flagged low voltage. The C2202 is usually an indication that the ABS has lost the VIN due to power loss.

You can go here and type in the codes to follow diagnostic steps.

I think the P0300 is unrelated to the ABS and could be a host of other causes.
