As a veteran technician, I’ve seen countless vehicle issues caused by improperly matched control modules. A common mistake is installing a used ECM from another vehicle without correct programming.

Frequently Asked Questions
Is any additional programming required after installation?
No. This ECM comes fully programmed to your vehicle’s VIN. In most cases, it is a plug-and-play installation. However, some vehicles may require a security relearn procedure, which is a simple process that can be done without any special tools. We include instructions for this procedure.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
How can I be sure this part will fit my car?
This module, part number 12630457, has a wide range of applications.
