Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is any additional programming required after installation?
No. This ECM comes fully programmed to your VIN with the latest GM updates. In most cases, it is a direct installation. However, some vehicles may require a simple security or key relearn procedure, which can be done without special tools. Instructions are readily available online for most models.
How do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my specific check engine light codes?
This ECM is a direct solution for codes related to internal module failure, such as P0601 through P0606. If your check engine light is caused by a faulty sensor or wiring, this will not resolve the issue. Proper diagnosis is always recommended before ordering.
Does this ECM fit other GM models besides the 2014-2016 Cadillac XTS?
Yes. This module is compatible with a wide array of GM vehicles, including various years of the Silverado, Sierra, Corvette, Camaro, Tahoe, and Escalade, among others. The provided fitment list details many of the compatible models.
