Hi,

If you are referring to the powertrain control module (brain), the new module needs to be programmed to the vehicle. You need to use a DRB scan tool to reprogram new PCM with the vehicle's original Identification Number (VIN) and original vehicle mileage. DRB is Chrysler's name for their scan tool. There are other upper-level scan tools that can do this.

If you are reprogramming the SKIM (Sentry Key Immobilizer Module), see the attachments below.

If you are referring to a different module, let me know which one it is.

Take care,

Joe
