Is your Chevrolet Aveo, Cruze, or Sonic giving you headaches? A persistent Check Engine Light, rough idling, stalling, or a complete failure to start can be incredibly frustrating.

An Expert’s Note on VIN Programming
“Many people think swapping an ECM is like changing a battery. But it’s more like a brain transplant for your car. Your vehicle’s VIN isn’t just a serial number; it’s a blueprint for its specific features—like the type of transmission, security system, and emissions equipment. Programming the ECM with your VIN ensures it knows exactly how to operate your car, not just a generic model. This step is the difference between a quick fix and a frustrating, non-working part. We handle this critical process for you, so you get a part that works correctly right out of the box.”
Take the guesswork out of your repair. This programmed 2009-2011 Aveo ECM is the most efficient and reliable way to get your car running properly again. Provide your VIN at checkout, and we’ll handle the rest, shipping you a part that’s ready to install and get you back on the road.
Frequently Asked Questions
What is a VIN and why do you need it?
Your Vehicle Identification Number (VIN) is a unique 17-digit code for your car. We require it to program the ECM with your vehicle’s specific software and security information, ensuring it communicates perfectly with all other modules upon installation.
Is this ECM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. It usually involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then reversing the process. We always recommend consulting a repair manual for your specific vehicle.
Will I need to perform any other procedures after installation?
In some cases, a simple security relearn procedure may be necessary, which can often be done without special tools. This process syncs the new ECM with your vehicle’s anti-theft system. We can provide general instructions for this common procedure.
How do I know for sure my ECM is the problem?
While the symptoms listed are strong indicators, professional diagnosis is the best way to be certain. Key signs include specific ECM-related diagnostic trouble codes (DTCs), a lack of communication with a scan tool, or having ruled out all other potential causes like sensors or wiring.

This ECM is compatible with a range of models, including the 2011-12 Cruze (1.8L), 2013 Spark, 2009-10 Wave, 2013-14 Trax (1.8L), 2012 Sonic (1.8L), and 2009-10 G3. It is a direct replacement for multiple part numbers, including the primary 2009-2011 Aveo ECM.
