Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive the VIN, as we need it to program the module correctly for your specific car.
Is this a brand new part?
No, this is a high-quality, tested, and fully functional used ECM that has been sourced from a salvaged vehicle. This allows us to provide a reliable, OEM-quality part at an accessible price point.
Will I need to do any additional programming?
No. The main programming is done by us before shipping. However, on most of these GM vehicles, you will need to perform a simple security relearn procedure which syncs the new ECM to your key. This typically involves a 10-30 minute key-on/key-off sequence and does not require any special tools. We can provide instructions for this process.
My original part number is 19210073. Will this work?
Yes. Part numbers 12576162 and 19210073 are interchangeable for the applications listed. We will ensure the unit you receive is 100% compatible.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty. This gives you peace of mind that you are receiving a quality, dependable part.
Where is this computer located on my vehicle?
The location varies slightly by model, as noted in the fitment list. For Cavalier and Sunfire, it’s in the right-hand rear of the engine compartment. For Alero, Grand Am, and Malibu Classic, it is located inside the vehicle, typically on the left-hand side of or center of the dashboard area.
