Is your Chevrolet Cruze, Sonic, or Aveo suffering from frustrating issues like a persistent check engine light, stalling, poor fuel economy, or a complete no-start condition?

Expert Insight: Why VIN Programming is Critical
As a technician with over 20 years of experience, I’ve seen countless drivers try to save a few dollars by installing a used ECM from a salvage yard. This almost always ends in failure. Without being programmed to your car’s specific Vehicle Identification Number (VIN), the module won’t recognize your engine, transmission, or security system. It’s like trying to use the wrong key for a lock. Our process of flashing the 2011-2012 Cruze 1.8L ECM 12630789 with your VIN ensures all vehicle systems communicate perfectly, just as the factory intended, giving you a reliable and lasting repair.

Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard visible through the windshield.
Is this really a ‘plug-and-play’ part?
Yes, for most vehicles. Because we program the ECM to your VIN before shipping, it eliminates the need for dealer-level tools. In some cases, a simple ‘security relearn’ procedure may be necessary, which can be done without special tools and typically takes 10-30 minutes. Instructions can easily be found online for your specific model.
Will this fix my specific problem?
This ECM corrects issues directly caused by a faulty engine computer. While it solves the most common electronic problems like communication errors, stalling, and no-start conditions, it’s always best to have a proper diagnosis to confirm the ECM is the point of failure. This part will not fix mechanical issues.
What if I order the wrong part?
Please double-check the fitment list and your original part number before ordering. Programming is specific to the VIN you provide, so it’s crucial to ensure this is the correct module for your vehicle. If you are unsure, please contact us with your VIN before purchasing, and we can help verify compatibility.
Do I need to send my old ECM (core) back?
No core return is required for this part. You can keep or responsibly dispose of your old module.
