Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship your ECM without it. This ensures the computer has the correct software and calibration for your specific vehicle options.
Will I need to do anything after installing the ECM?
Possibly. In many cases, the vehicle will start and run correctly. However, due to GM’s security systems, a ‘theft deterrent relearn’ may be necessary if the vehicle does not start. This procedure syncs the new ECM to your vehicle’s anti-theft system and requires a professional tool, such as GM’s TIS2Web system. The buyer is responsible for this and any other necessary relearns (e.g., crankshaft variation, injector setup).
Is this a new part?
No, this is a genuine, used GM part sourced from a salvaged vehicle. Each unit is carefully inspected to ensure it is in excellent working condition before being programmed and shipped to you.
How can I be sure this ECM fits my vehicle?
The best way is to match the service number (serv.no) 12669908 on your original ECM. You can also check the detailed fitment list on this page. Providing us with your VIN during checkout allows us to perform a final compatibility check for you.
Where is this part located on my vehicle?
On most compatible models like the GMC Terrain, Chevy Equinox, and Buick Regal, the ECM is located in the engine compartment on the driver’s side (LH side), often near or above the battery.
