Is your GM truck, van, or SUV suffering from frustrating issues like a persistent check engine light, unexplained stalling, rough idling, or poor fuel economy?

This professionally programmed 12629009 Engine Control Module is the definitive, hassle-free solution to restore your vehicle’s performance and dependability.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used ECM from a salvage yard. The result is almost always the same: a vehicle that still won’t start or runs even worse. That’s because an ECM is not a one-size-fits-all part. It’s programmed with the specific VIN, options, and anti-theft information for the original vehicle. Our VIN programming service isn’t just a convenience; it’s the critical step that makes this repair successful, saving you from the frustration and added expense of a failed installation.
Getting your work van back in service or your family SUV running safely is our top priority. By providing us with your VIN after purchase, you’re ensuring you receive a correctly configured 12629009 Engine Control Module that’s ready to get the job done right the first time.
Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will provide us with your vehicle’s 17-digit VIN. Our technicians then use this VIN to load the correct GM-certified software and calibration files onto the module, making it a perfect match for your vehicle’s specific configuration.
Is this part truly plug-and-play?
For the vast majority of vehicles, yes. Once programmed to your VIN, it will not require additional programming. However, some GM vehicles have an anti-theft system (Passlock/VATS) that may require a simple security relearn procedure. This procedure can typically be done by you without any special tools and instructions are readily available online.
Where can I find my vehicle’s VIN?
You can find your 17-digit VIN in several places: 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.
My original part number is 12625455. Will this work?
Yes. This 12629009 Engine Control Module is a fully compatible and updated replacement for part number 12625455. Please confirm your vehicle is on the fitment list to ensure proper application.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the part itself in the event of failure within one year from the date of purchase. We are committed to providing a reliable, quality part.
