I got a 2001 Dodge 2500 with a Cummins engine. I need to change the PCM (not the ECM) Which scanner is capable of changing the Vin and the milage. And what software does it have to have? TIA Eric
What scanner will work?

If its a used PCM you will not be able to change the VIN or disable security if so equipped.
If it is a used PCM without security enabled it will work, but have the wrong VIN.
If it is a new PCM most of the Snap On scanners can write a new VIN only.
As far as I know, there are no Sentury (SKIM) keys on that year model truck.
The only people I have found that can change VINs and disable security are the ECM rebuilders and some aftermarket tuning suites. The dealer (our dealer) cannot remove/change either one.
I have done quite a few of these style PCM swaps.
Sometimes you will have ABS VIN mismatch DTCs in the ABS module.Comment

If it is something that can be done with a scan tool , the scan tool needs to at least stil be able to communicate with the bad ECU to pull out the necessary information first. Here is a you tube video of how every day Smucks can do it without a J-box or a paid sub.I'm sure some relearns and adaptations might be in order besides

Is this abs happen with that old of a truck. It's a regular key no micro chips in key. It's black head key
Today 04:50 PM
Maybe just before the donor PCM is installed , besides the SKIM module being unplugged, maybe the ABS module should also be disconnected until the Scan tool Force Writes the VIN and the other transferred coding to the PCM , and after turning off key , plug them back in.Comment

I have changed VINs,but not mileage with Solus Ultra.With DRB III and secret pin(if it has skim) I have installed several used ECM/PCM on Dodge trucks,but sometimes even after setting pinion factor the ABS light stays on with various mismatch codes.Comment
