Is your Buick Encore, Chevy Cruze, or Sonic running poorly, stalling unexpectedly, or refusing to start? A faulty Engine Control Module (ECM) is often the culprit behind these frustrating and complex issues. The ECM is the central computer of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions controls. When it fails, it can cause a cascade of problems that can be difficult to diagnose. This genuine GM Engine Control Module, part number 12692200, is the direct-fit, reliable solution to restore your vehicle’s performance, fuel economy, and dependability.
The Plug-and-Play Solution: Programmed Specifically for Your Vehicle
One of the biggest hurdles when replacing a modern ECM is the need for expensive and complicated programming at a dealership. We eliminate that step entirely. Before we ship your part, our technicians will flash this module with the latest official GM software updates, programmed specifically to your vehicle’s unique Vehicle Identification Number (VIN). This ensures seamless integration with your car’s existing systems, including the ignition, security, and transmission modules. You receive a part that is ready for installation right out of the box, saving you hundreds of dollars in dealership programming fees and valuable time.
From the Diagnostic Bay
We had a 2014 Chevy Sonic come into the shop with a ghost of a problem. The owner complained of intermittent stalling at stop lights and a random check engine light that would come and go. We checked the fuel system, ignition coils, and sensors, but everything tested fine. The codes stored were vague communication errors. After hours of diagnostics, we decided to monitor the live data from the ECM. We noticed that the voltage readings for the throttle position sensor would erratically drop out, but only when the engine was hot. The sensor itself was new. On a hunch, we swapped in a known-good ECM. The problem vanished instantly. The original ECM had an internal failure on the 5-volt reference circuit that only manifested under specific temperature conditions. A replacement, VIN-programmed module like this one had the car running perfectly in under an hour, solving a problem that had plagued the owner for months.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide us with your vehicle’s VIN during or after checkout, and we will load the correct software and key information. This makes the installation process much simpler.
Is the installation process difficult?
For most models, the ECM is located in the engine bay and is accessible with basic hand tools. The process typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. While it is a straightforward job for a DIY mechanic, we always recommend consulting a service manual for your specific vehicle.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue and allow the light to be cleared. However, it’s crucial to ensure the ECM is the actual source of the problem. We recommend a proper diagnosis to rule out other potential issues like faulty sensors or wiring problems.
What is a ‘relearn’ procedure?
Some vehicles may require a simple ‘relearn’ procedure after the new ECM is installed. This can include a security relearn (often as simple as cycling the key in the ignition) or a Crankshaft Position Sensor relearn. These procedures can typically be performed without special tools, and instructions are widely available online or in service manuals.
