Get Your Car Running Right Again
Is your Chevrolet Aveo, Cruze, or Sonic stumbling, stalling, or showing confusing check engine lights? A faulty Engine Control Module (ECM) can turn your reliable daily driver into a source of constant stress, causing issues from poor fuel economy to a no-start condition. Get back on the road with confidence with this fully programmed, VIN-matched replacement ECM, designed to restore your vehicle’s performance and reliability.
Common Symptoms & Your Solution
If you’re experiencing issues like a persistent check engine light, rough idle, engine misfires, or a sudden drop in gas mileage, the ECM is a likely culprit.

This isn’t just a part; it’s a direct solution. We eliminate the guesswork by programming this genuine GM ECM specifically to your vehicle’s VIN before it ships. This ensures your new 2009-2011 Aveo ECM works correctly right out of the box, saving you from an expensive and time-consuming trip to the dealership.

Frequently Asked Questions
Do I need to send you my old ECM?
No, there is no core charge or need to send us your original part. This is a direct replacement unit that we program and ship to you.
Is any additional programming needed after installation?
In most cases, no. We program the ECM to your vehicle’s VIN, so it should be plug-and-play. However, some vehicles may require a simple security relearn procedure, which can typically be done without special tools. Instructions are widely available online or in your vehicle’s service manual.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship the module without it. You can typically find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard near the windshield.
How do I know if my ECM is the problem?
Common signs include a check engine light with communication codes (U-codes), multiple unrelated sensor codes, stalling, or a no-start condition where the engine still cranks. While these symptoms point to the ECM, we always recommend a proper diagnosis by a qualified mechanic to confirm the failure before ordering.
What does “plug and play” mean for this part?
It means the unit arrives ready to be installed without the need for expensive dealership programming. Because we flash it with your car’s specific VIN and software, it’s ready to integrate with your vehicle’s systems as soon as it’s connected.
Is this compatible with a 2012 Chevy Cruze with the 1.8L engine?
Yes, according to our fitment data, this ECM is compatible with the 2011-2012 Chevrolet Cruze equipped with the 1.8L engine. We will confirm perfect compatibility when you provide your VIN.
