Is your vehicle suffering from frustrating and unpredictable engine problems? A flashing check engine light, poor fuel economy, stalling, or a complete no-start condition often points directly to a failing Engine Control Module (ECM). Get your vehicle running reliably again with this genuine GM Engine Control Module, which arrives fully programmed to your specific Vehicle Identification Number (VIN). This eliminates the need for an expensive trip to the dealership for programming, saving you time, money, and hassle.

A faulty ECM can cause a wide range of issues that can be difficult to diagnose. If you’re experiencing any of the following, this pre-programmed module is the definitive solution:
- Check Engine Light (CEL) is on with communication codes (U-codes) or internal processor codes (P0600-P0606).
- Engine stalling, stumbling, or hesitating during acceleration.
- Noticeable decrease in fuel efficiency.
- Transmission shifting issues or harsh engagement.

An Expert’s Note on Installation
As a technician with over two decades of experience, I’ve seen countless drivers get stuck between a rock and a hard place. Their car won’t run right, the diagnosis points to the ECM, but the cost of a new unit plus dealer programming is astronomical. This service is the exact solution I recommend. You get a quality part that’s already ‘taught’ to recognize your vehicle. For many models, installation is straightforward, though some may require a simple security relearn procedure (often called a ‘key relearn’ or ‘anti-theft relearn’), which you can typically do yourself in your driveway with just your key. This simple step saves you hundreds compared to a tow and a day at the dealership.
Frequently Asked Questions
What is VIN programming and why is it essential?
VIN programming loads your vehicle’s unique identification number and specific operational parameters onto the ECM. This is crucial for the module to communicate correctly with your engine, transmission, anti-theft system, and other onboard computers. Without it, the vehicle will not start or run properly.
Is this a simple plug-and-play installation?
Yes, for most vehicles. Because we program it to your VIN, the module is ready to be installed. However, some GM vehicles require a security or anti-theft relearn procedure after installation. This can usually be done without special tools and instructions are widely available online or in your vehicle’s service manual.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive your VIN.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM (e.g., codes P0601-P0606), then this part will solve the problem. It’s important to ensure the ECM is the root cause of the issue. We always recommend clearing all codes after installation.
How can I confirm this part fits my vehicle?
Please review the detailed fitment list on this page. The most reliable method is to match the service number on your current ECM to 12607096 or one of the interchangeable numbers listed. If you are still unsure, please contact us with your VIN, and we will be happy to verify compatibility for you.
Is this the correct part if my old one has a different service number?
Yes, it can be. GM frequently updates part numbers. This Programmed 12607096 ECM is the correct replacement for all service numbers listed in the description, such as 12590032, 12602044, 12603530, and others. We ensure it’s programmed to function perfectly for your specific application.
