Restore Your Vehicle’s Performance and Reliability
Is your 2009-2010 GM vehicle suffering from perplexing issues like stalling, erratic shifting, poor fuel economy, or a persistent Check Engine Light? These are common signs of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt everything from engine timing to transmission function, leaving you with an unreliable and frustrating driving experience. This replacement Engine Control Module, part number 12629009, is the definitive solution to restore your vehicle’s factory performance and get you back on the road with confidence.
The Heart of Your Vehicle’s Operation
The ECM is responsible for managing a complex network of sensors and actuators to ensure your engine runs efficiently and cleanly. It controls the fuel injectors, ignition coils, throttle position, and dozens of other critical parameters. When it begins to fail, the symptoms can be varied and difficult to diagnose. Replacing it with a properly functioning unit is essential for your vehicle’s health and your peace of mind.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is on with codes related to the ECM (e.g., P0600-P0606) or communication errors.
- ✔ Engine stalling, stumbling, or hesitating for no apparent reason.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Transmission shifting harshly or at the wrong times.
- ✔ Vehicle won’t start, even with a good battery and starter.
- ✔ Unexplained loss of power during acceleration.
- ✔ Intermittent issues with other electronic components.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN is essential for programming the ECM with the correct software and calibrations for your specific engine, transmission, and options. This ensures seamless integration and proper function without any additional dealer programming.
Is this part difficult to install?
For most compatible vehicles, 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 ECM, unbolting it, and then installing the new one in reverse order. Since our module comes pre-programmed, no further steps are needed.
Will this fix my vehicle’s specific problem?
This ECM will correct issues directly caused by a faulty engine computer. While the symptoms listed are common indicators of ECM failure, it’s always recommended to have a proper diagnosis performed to rule out other potential causes like sensor or wiring problems.
What if I have a different part number?
This module is a direct replacement for part numbers 12629009 and 12625455. If your original module has one of these numbers, this part is a guaranteed fit. Please check the extensive fitment list to confirm compatibility with your make and model.
Is any other setup required after installation?
In most cases, no. Our VIN programming makes this a plug-and-play part. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for this simple procedure.
