Dodge / RAM ECU VIN Programming
If you have replaced your Dodge or RAM PCM with a used or donor unit and the VIN does not match the rest of the vehicle, the PCM needs to be reprogrammed with your VIN before wiTECH / DRBIII / emissions monitors agree with the rest of the network. We perform Dodge VIN programming on the bench for compatible PCM generations including the popular RAM 5.9L Diesel CM848B / CM848C service.

Not Sure Which Service to Choose?
If you are unsure which option matches your Dodge module, the safest path is to email or text us photos before ordering: full label of the original module, full label of the donor module if you already have one, the part number, hardware revision, and software/calibration sticker, and a photo of the connector pinout if visible. We will confirm whether the service is supported for your specific part number and hardware revision before you order and ship.
Compatibility Warning
VIN programming requires the original PCM to be readable and the target VIN to be valid for the PCM hardware/calibration.
What to Ship
- Your original Dodge module (the failed/locked unit), clearly marked “ORIGINAL”
- If applicable: a donor module, clearly marked “DONOR” — same part number family and hardware revision as the original
- Your order receipt printed, or order number written on a slip in the box
- Your return shipping address
- Ship to the address shown on your order receipt at checkout (we operate from 2 locations and route based on tool availability and turnaround)
