Frequently Asked Questions
Do I need to send you my old ECM?
No, there is no core charge or need to send us your old module. This is a direct purchase. We program a replacement unit and ship it to you.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your programmed 2015-2016 Yukon XL 1500 ECM without it.
Is any additional programming required after installation?
While the main engine programming is complete, you will likely need to perform a security relearn procedure (often called a CASE relearn or anti-theft relearn). This process syncs the new ECM with your vehicle’s security system and can typically be done without special tools. Instructions are readily available online or in service manuals.
How do I find my VIN?
Your VIN can be found on a sticker on the driver’s side door jamb, on a plate on the driver’s side of the dashboard visible through the windshield, or on your vehicle’s registration and insurance documents.
Is this compatible with other part numbers?
Yes, this ECM is a direct replacement for several part numbers, including 12692067, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, and 12669318. Please check the provided fitment list to confirm it matches your vehicle.
