Frequently Asked Questions
Do I need to have this computer programmed?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the ECM will arrive ready to install.
What information do you need from me?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to flash the ECM with the exact software and calibrations for your specific Traverse.
Is this part difficult to install?
The ECM on a 2012 Traverse is located behind the fan shroud, making it reasonably accessible. For most people with basic mechanical skills, it’s a straightforward installation that involves disconnecting the battery, unplugging a few connectors, and swapping the module. However, if you are not comfortable working on your vehicle, we always recommend professional installation.
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 check engine light?
If the check engine light is on due to an internal failure of the ECM, this part will solve the problem. After installing the new 2012 Traverse ECM 12643248, it’s essential to clear any existing codes from the system with a standard code reader.
What if my original part number is slightly different?
This ECM is a direct replacement for several GM part numbers, including 12651994, 12643248, and 12652814. As long as your vehicle is listed in the compatibility chart, this unit will function correctly.
