Is your Chevrolet Cruze, Sonic, or Trax suffering from frustrating engine issues like a persistent check engine light, rough idling, stalling, or poor fuel economy? These are classic signs that the brain of your engine, the Engine Control Module (ECM), may be failing. Don’t let a faulty computer keep you off the road. This direct-fit replacement ECM, part number 12692200, is the reliable solution to restore your vehicle’s performance and drivability.
The biggest challenge when replacing an ECM is the complex and expensive programming required at a dealership. We eliminate that hassle entirely. When you purchase this module, we will flash it with the latest, most stable GM-certified software specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at checkout. This ensures that when the part arrives, it’s a true plug-and-play solution, ready to communicate perfectly with your vehicle’s existing systems.
We had a 2014 Chevy Sonic come in with a really tricky problem. The owner complained of random stalling at stoplights, but there were no consistent trouble codes—just a generic U-code now and then. We checked the fuel pump, sensors, and wiring, but everything seemed fine. On a hunch, we monitored the live data from the ECM and noticed that the voltage readings for the throttle position sensor would flicker erratically just before a stall. The sensor itself was fine. The culprit was the ECM itself, with an internal fault causing it to misinterpret sensor data. Replacing it with a properly programmed unit like this one solved the problem instantly. It’s a reminder that the ECM can cause some of the most elusive and frustrating symptoms.

Common Symptoms of a Failing GM ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Engine stalling or hesitation during acceleration
- ✔ Rough or unstable engine idle
- ✔ Noticeable decrease in fuel efficiency
- ✔ Misfires or poor engine performance
- ✔ Automatic transmission shifting erratically or harshly
- ✔ Vehicle fails to start intermittently or completely (no-start condition)
- ✔ Communication errors with diagnostic scan tools
This replacement 2012-2016 Cruze ECM is your first step towards a smooth-running, reliable vehicle. Once installed, some vehicles may require a simple security relearn procedure (often called a key relearn), which can typically be done in your own driveway without any special tools. We provide instructions for this process. Get your car, truck, or van running like new again with a dependable, correctly programmed engine computer.
Do I need to program this ECM?
No. This Engine Control Module comes fully programmed to your vehicle using the VIN you provide during checkout. It will have the latest GM software updates, making it ready for installation right out of the box.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific vehicle. We use it to load the exact software and calibrations your car requires, ensuring perfect compatibility with its engine, transmission, and options.
Will this fix my car’s problem for sure?
This ECM is a common solution for many engine performance and drivability issues. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will fix the problem if the original ECM is indeed the faulty component.
Is installation difficult?
For most models, the physical installation is straightforward, involving disconnecting the battery and swapping the module. After installation, a ‘security relearn’ or ‘key relearn’ procedure may be necessary, which can often be performed without special tools. We recommend consulting a service manual or a professional mechanic if you are not comfortable with the process.
What’s the difference between an ECM and a PCM?
The terms are often used interchangeably. ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. A PCM controls both the engine and the transmission, while an ECM typically controls only the engine. In most modern GM vehicles like the Cruze, the unit is technically a PCM, but the term ECM is widely understood and used.
