An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Many sellers offer blank or used units, forcing you to find a specialized shop with expensive tools to program it—a hidden cost and a major hassle. Our process eliminates that entire step. By programming the GM 22819494 ECM to your VIN before we ship, we are delivering a component that is truly ready for installation. This critical step ensures the module correctly recognizes your engine, transmission, and all onboard security systems, saving you time, money, and diagnostic headaches.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is like your car’s DNA. It allows us to load the exact software and calibrations specified by GM for your vehicle’s engine, transmission, and options. This step is crucial for ensuring the ECM works perfectly upon installation.
Is any additional programming required after I install it?
No. Because we program the module to your VIN before shipping, it is ready to be installed. In most cases, a security relearn procedure may be required, which is a simple process that can be done without special tools. We can provide instructions for this.
Will this fix my check engine light?
If the check engine light and related symptoms are caused by a faulty ECM, this part will resolve the issue. It is always recommended to have a professional diagnosis to confirm the ECM is the point of failure before ordering.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is a required step.
Is this part compatible if my old module has a different part number?
Yes. This ECM, part number 22819494, is the correct service replacement for all the part numbers listed in the description, including 12668866, 12643636, and others. GM often consolidates part numbers over time.
