This VIN programming write service is required when installing a used or remanufactured ECU, ECM, or PCM into select 1996–2013 Chrysler, Dodge, and Jeep vehicles. These control modules store the vehicle’s VIN internally, and without proper VIN programming, installation issues, fault codes, or communication problems may occur.

This service programs your vehicle’s VIN into the module you provide, allowing proper integration with the vehicle’s systems. No software updates or calibrations are included—this service strictly performs VIN writing.

What This VIN Programming Service Does

We write your vehicle’s VIN into the ECU, ECM, or PCM you supply so the module matches the vehicle it is being installed into. Once programmed, the module can be installed and function normally without dealership VIN initialization.

Turnaround time is typically same or next business day once the module is received.

Important Compatibility Requirements

For this service to be successful, the following conditions must be met:

• The part number on the “Authorized Service Update” sticker must match your original module

• This service does not include software updates or reflashing

• Some vehicles may store fault code P0633 after VIN programming

• P0633 will not illuminate warning lights or affect vehicle performance, per Chrysler Service Bulletin #08-030-06 REV A

If you are unsure about compatibility, contact us with your module part number before shipping.
