Restore Peak Performance to Your General Motors Vehicle
Is your Chevrolet, Buick, GMC, or Cadillac suffering from frustrating and persistent issues like a constant check engine light, poor fuel economy, stalling, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the entire system can become unreliable. This pre-programmed ECM, part number 12644446, is the definitive solution to get your vehicle back on the road and running smoothly.
From the Diagnostic Bay
We once had a 2014 Chevy Equinox come in with a persistent P0606 code (ECM/PCM Processor Fault). The owner had already replaced the spark plugs and an oxygen sensor at another shop, with no success. After confirming power and ground to the module were solid, we knew the internal processor was the culprit. Instead of a costly trip to the dealership for a new unit and programming, we sourced one of our reliable, VIN-programmed modules. The installation was straightforward, and after a quick security relearn, the Equinox ran perfectly. The customer saved hundreds of dollars and significant time, avoiding a lengthy dealership appointment.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is illuminated with various trouble codes (DTCs).
- ✔ Engine stalling, misfiring, or running rough.
- ✔ Unexplained drop in fuel efficiency.
- ✔ The vehicle fails to start or has intermittent starting problems.
- ✔ Automatic transmission shifting issues or harsh engagement.
- ✔ Loss of power and poor acceleration.
- ✔ Communication errors with diagnostic scan tools.

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 your vehicle’s VIN during or after checkout, and we will flash the unit with the correct software for your specific car. It will arrive ready to install.
Is this a new part?
This is a high-quality, tested, and fully functional used ECM sourced from a salvaged vehicle. Each unit is inspected to ensure it meets our strict quality standards before being programmed and shipped.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. You can typically find it on a small plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What happens if I forget to provide my VIN?
We cannot ship your order without a VIN, as the programming is essential for the part to function in your vehicle. Our team will contact you via email to request the VIN. To avoid delays, please provide it at the time of purchase.
Will I need to perform any other procedures after installation?
In many cases, you may need to perform a simple security relearn procedure, also known as a Passlock or anti-theft relearn. This can typically be done without special tools and involves a sequence of key turns. Instructions are widely available online for your specific model, or you can consult a service manual.
