Real-World Repair Story: The Phantom Misfire
Do I need to do any programming or flashing myself?
No. We handle all the programming for you before the part ships. We use your VIN to load the latest, most stable software from GM, making this a true plug-and-play part. Some models may require a simple security relearn procedure, which does not require special tools.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is this part compatible with other part numbers?
Yes. This ECM, 12622175, is a direct replacement for several other GM service numbers, including 12636659, 12639300, 12628993, and more, as listed in the fitment section. This ensures broad compatibility.
What if my original part number isn’t listed?
If your part number is not on our interchange list but your vehicle model and year are, please contact us with your VIN. We can verify compatibility to ensure you receive the correct part for your specific application.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (common codes P0601-P0606), then this part is the correct fix. It is crucial to properly diagnose the vehicle first, as other failing sensors or wiring issues can also trigger a check engine light.
