Restore Peak Performance and Reliability to Your Vehicle
Is your car suffering from frustrating issues like stalling, a no-start condition, an illuminated Check Engine Light, or erratic performance? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your engine’s operation. When the ECM falters, it can cause a cascade of problems that are often difficult to diagnose. As a technician with over two decades of experience, I’ve seen countless drivers spend a fortune chasing down sensor or wiring issues when the root cause was the ECM all along.
This Engine Control Module, part number 12650256, is the definitive solution. We take the guesswork and high costs out of the equation. Unlike a trip to the dealership, this module arrives at your door fully programmed with the latest GM software updates specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our experts will handle the complex flashing process. This means no expensive specialty tools or dealer appointments are required for installation, making it a perfect project for a DIY enthusiast or a time-saving solution for a professional repair shop.
From the Diagnostic Bay
I remember a 2012 Chevy Impala that came into the shop with an intermittent stalling problem that no one could figure out. The owner had already replaced the fuel pump and a couple of sensors. The car would run fine for days, then suddenly die at a stoplight. After hooking up my scan tool, I noticed intermittent communication loss with the powertrain controller and a stored history code P0601 (Internal Control Module Memory Check Sum Error). Instead of hours of complex wiring tests, we started with the most likely culprit. We installed a pre-programmed ECM just like this one. The swap took less than 30 minutes. The Impala never stalled again, and the customer was thrilled to have a reliable car back without the massive diagnostic bill.

A Straightforward Guide to Installation
Installing your pre-programmed module is a simple process that requires basic hand tools. This procedure can typically be completed in under an hour.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical damage.
- Locate the ECM: On most compatible vehicles, the ECM is found in the engine compartment, often on the driver’s side near the air filter box or firewall.
- Disconnect Connectors: Carefully release the locking tabs and unplug the main wiring harness connectors from the old module. Inspect them for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt your new, pre-programmed ECM into place. Reconnect the wiring harness connectors, ensuring they click securely into place.
- Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start. In some cases, a security or crank relearn procedure may be needed, which can often be done without special tools.

Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before shipping it. It arrives ready for installation.
What is a VIN and where do I find it?
The VIN is your car’s unique 17-digit identification number. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side dashboard visible through the windshield.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal ECM failure (like code P0601), this part will resolve the issue. If the light is on for another reason, such as a bad oxygen sensor, that separate problem will still need to be addressed.
Is this a brand new part?
This is a high-quality, tested, and verified used component that has been professionally programmed with the latest software for your vehicle, offering a reliable and cost-effective alternative to a new dealer part.
How do I provide my VIN after ordering?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your module until we receive this information.
