I have a problem with the tcm of my dodge dart 2013. The obd2 scan was placed and it says lost communication with the tcm. I turn on the light of the engine and what I do is disconnect the negative from the battery and then turn on the dart but if I do not do this it does not turn on, either in the engine light no shuts off.

I researched and I saw in a place that the tcm of dart 2013 onwards came with problems and that the 2012 fiat 500l and dodge dart 2012 models do not have problems, but I would like the opinion lived by some regarding this problem.

The tcm of dodge dart 2012 can be used in my dodge dart aero 2013.

Tcm dart 55257645. P 68210293AA this is the one that I use

Tcm 500l and dart 55245644. P 68033642AF

if this does not work could I use the tcm other that ddct c635?

Has recall campaign R42 been completed on your Dart? The cause of the TCM issues was the mounting bracket it was attached to causing it to flex too much. The recall involves replacing the bracket, installing a brand new TCM, and flashing it with the latest TCM software.

If you don't know, you can check if there are any recalls outstanding on your car here:

If R42 doesn't show up, it's been completed.

As for your other questions, if the TCM is the problem (you should have a "SERVICE TRANSMISSION" error on your dash), it will likely need to be replaced. You can't just use the TCM from another vehicle, and I'm pretty sure this is one of the few parts that must be installed by an FCA dealership. The reason is that the new TCM comes to the dealership blank, with no program loaded, and the programming is only added to it after it is installed in the car. The programming is proprietary, so while you could theoretically purchase a TCM and install it yourself, it wouldn't actually work. Unfortunately, unless you have some kind of extended warranty, you will have to pay for this service.

NOTE: There is no such thing as a 2012 Dart.

I brought the dart of the U.S. towards Dominican Republic.


The vin:

THE TRANSMISSION CONTROL MODULE (TCM) MOUNTING BRACKET MAY CAUSE THE PRINTED CIRCUIT BOARD SOLDER JOINTS TO SEPARATE, RESULTING IN AN ELECTRICAL OPEN CIRCUIT IN THE TCM. AN OPEN CIRCUIT IN THE TCM COULD CAUSE THE TRANSAXLE TO SHIFT INTO NEUTRAL WITHOUT WARNING. HAVING THE TRANSAXLE UNINTENTIONALLY SHIFT INTO NEUTRAL UNDER CERTAIN DRIVING CONDITIONS COULD CAUSE A CRASH WITHOUT WARNING.

Repair Description

THE TCM AND THE TCM MOUNTING BRACKET MUST BE REPLACED.


the dart is in the Dominican Republic

What I can do?

I hate to be the bearer of bad news, but short of bring the car back to the United States, I can't see how you can solve your problem. Your car almost certainly needs this recall to be completed in order to work again, but only dealerships in the United States and Canada (the only places where the Dart was ever officially sold) are authorized to do it. I feel bad for your predicament, but importing a 2013 Dart 1.4T DDCT into a country where it was never sold and where it has no support is a very risky thing to do for exactly this reason.
