An Expert’s Note on VIN Programming
“I’ve seen countless drivers chase their tails replacing sensors and wiring, only to find the root cause was the ECM all along. The most critical step in this repair is the VIN programming. It’s not just about making the engine run; it’s about telling the computer about every specific option in your vehicle—the type of transmission, security system, cruise control, and more. A generic, un-programmed module from a junkyard will almost always lead to more problems. Our process ensures the new ‘brain’ knows your vehicle inside and out from the moment you plug it in, which is the key to a successful and lasting repair.”
Frequently Asked Questions
Do I need to do any programming after I receive this?
No. This ECM arrives fully programmed to your vehicle’s specific VIN number. It is designed to be a plug-and-play solution, though a simple security relearn procedure (often outlined in your owner’s manual or easily found online) may be necessary for your key to be recognized.
Where do I provide my VIN?
You can provide your 17-digit Vehicle Identification Number (VIN) during the checkout process. If you miss it, you can also send it to us with your order number. We cannot ship the part until we have your VIN to program it.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (often indicated by codes like P0601 or P0606), this part is the correct solution. However, you should always ensure a proper diagnosis has been performed, as other failing components can also trigger a check engine light. This 2009 Envoy ECM 12622175 is the fix for a faulty computer.
Is this a brand new part from GM?
This is a quality, tested component that has been professionally prepared and programmed with the latest official GM software. It is a reliable and cost-effective alternative to a new dealership part, designed to restore original functionality.
What if this part doesn’t fix my problem?
We guarantee this module is a functional, correctly programmed part. If your vehicle’s issues persist after installation, it indicates the problem may lie with another component. We highly recommend a thorough diagnosis by a qualified technician to confirm the ECM is the point of failure before ordering.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the module itself in the unlikely event of a functional failure within one year of the purchase date. Please contact us for assistance if you believe your unit has failed.
