Dodge VIN Programming on Diesel PCM
Can only the DRB program the VIN into the PCM, which is the TCM in this vehicle? I have tried Snap-on, Autel, Launch, and Toolbox 3 with no success. Toolbox 3 is the only one that gave me the option to write the VIN however it will not write it into the replacement PCM. This is a replacement from Chrysler and not a used one. Does anybody else have any tips or tricks on how to program the VIN into the PCM?
Every chrysler ecu ive installed needs to be flashed. They don't have the flash file in them. Flash the ECU with legacy.
If it's used you MUST use DRB on diesel ECM. I've been through this many times. If it's New, must first flash with legacy application as stated, then perform "ECM Replaced" with DRB3. I have never been able to write diesel vin pre 2006 with any aftermarket tool - drb3 emulator works with j2534
The J2534 process as you noticed will not do the VIN. Truck will operate fine, but will have the code for it. I have the CTC box which was the preferred tool for a while for J2534, and I'm pretty sure the software for that device has a VIN write feature that will write the VIN. Did a few Cummins ECMs awhile back for similar year trucks and pretty sure it worked, after having the Cardaq-M give me…
Hi Karl: The short answer is yes. All of the service information is part of your subscription. Make use of it. The "tip" is to read all of the bulletins because they may supersede others, especially since Tech Tools has changed. I know. You didn't ask about programming. There are a few scan tool functions which need to be done. These have nothing to do with programming the module though…
Correct. Only DRB or DRB emulator. I just did one today.

As mentioned the easiest way is with a DRB3 emulator by controller technologies.
I believe it isn’t possible with anything else.
There is always EEPROM/PCB level work, but not many people take it to that level.
Is there? I haven‘t heard of anyone doing this job that way.
It’s possible. Is it feasible? Probably not. I personally suggest the DRB 3 route. It is much less invasive.
Thanks Tim. I didn’t realize you had the DRB.
Autel scan tool will work if you can get into the PCM with it. Autel scan tool cannot decipher between the PCM and the ECM properly. I succesfully programmed the VIN on one of these trucks by disconnecting the Cummins ECM on the engine which then forced the Autel to communicate with/enter into the firewall mounted PCM. Once confirmed that I was in the PCM by the data pids I went into programming…
Yes Virginia, there is a Santa Claus. ECU-Engineer is currently in development and has the ability to change VIN on pre and post CAN Cummins Dodge trucks. It works on gasoline pre and post CAN. It will change the SKIM to non-SKIM module. It will clear both VINs and completely reset TIPM module, It is hopeful a production model will be ready for Industry week. After Chrysler variants are…
That would be great! Chrysler Witech 2.0 can't change VIN in post CAN Dodge Cummins engine module (correct me if I'm wrong). A system like that would have saved me hours of labor.
The software currently from Keenan is similar. What is being developed has more options.
Nice to know Mike, please keep me/us with an update!!
