Is your 2007 Chevrolet Monte Carlo—or another compatible GM vehicle—suffering from erratic behavior, a persistent check engine light, or frustrating no-start conditions? These are classic signs of a failing Engine Control Module (ECM), the computer that acts as your vehicle’s brain. A faulty ECM can disrupt everything from fuel delivery to transmission shifting, making your vehicle unreliable. This pre-programmed module is your direct, dealership-free solution to restore your vehicle’s health and your confidence on the road.

Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check the VIN for accuracy to ensure a perfect match.
Is this module truly ‘plug and play’?
Yes, for most vehicles. The engine and transmission programming is complete. However, on many GM vehicles, you may need to perform a simple security relearn procedure (often called a ‘key relearn’ or ‘anti-theft relearn’). This procedure takes about 30 minutes, requires no special tools, and syncs the new ECM to your existing keys. Instructions are widely available online for your specific model.
How do I find my vehicle’s VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
My original ECM has a different part number. Will this work?
Yes, as long as your original part number is one of the compatible numbers listed: 12589297, 12597121, 12603892, or 19210738. This module is a direct hardware replacement for all of those part numbers.
Will this fix my check engine light?
If the check engine light and performance issues are caused by a faulty ECM, this part is the correct solution. However, it’s crucial to ensure your vehicle has been properly diagnosed. This module will not fix problems related to other failed sensors or mechanical components.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the module itself in the event of failure during the warranty period. It does not cover installation labor or diagnostic costs.
