Restore Peak Performance to Your Vehicle’s Engine
Is your Chevrolet Malibu or other GM vehicle suffering from erratic behavior, a persistent Check Engine Light, or a frustrating no-start condition? The Engine Control Module (ECM), often called the engine computer, is the brain of your vehicle’s powertrain. When it begins to fail, it can cause a cascade of confusing and debilitating issues, from poor fuel economy to complete engine shutdown. This replacement Engine Control Module, part number 12602044, is the definitive solution to restore your vehicle’s factory performance, drivability, and reliability.
Unlike a generic part from a local auto store, this ECM is delivered to you fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest, most stable software updates directly from GM. This means no expensive trips to the dealership for programming, no special tools required for installation, and no guesswork. It’s a true plug-and-play solution designed to get you back on the road quickly and confidently.
From the Diagnostic Bay
We had a 2009 Malibu come into the shop with a complaint of intermittent stalling at stoplights and a check engine light that would come and go. The owner had already replaced the spark plugs and an oxygen sensor with no luck. Our initial scan showed a handful of seemingly unrelated codes, from injector circuit faults to communication errors. This is a classic sign of a failing ECM. The internal logic boards and driver circuits can degrade over time, sending faulty signals and misinterpreting sensor data. After confirming power and ground to the module were solid, we installed a VIN-programmed ECM. The car started immediately, idled smoothly, and all the ghost codes vanished. It’s a reminder that when multiple unrelated systems act up, the central controller is often the culprit.
Symptoms of a Failing Engine Control Module

- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Rough or unstable idling.
- ✔ Transmission shifting issues or harsh engagement.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass emissions testing.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming before we ship the part to you. By providing your VIN, you will receive a module that is ready to be installed without any need for expensive dealership tools or software.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is this a difficult part to install?
For most DIY mechanics, this is a straightforward installation. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old ECM, unbolting it from its bracket, and then reversing the process with the new unit. The location varies by model, so consulting a repair manual for your specific vehicle is always recommended.
What if I have an anti-theft system?
Our programming service accounts for your vehicle’s factory anti-theft system (Passlock, VTD, etc.). In most cases, the module will sync with your vehicle automatically. Occasionally, a simple key relearn procedure may be necessary, which involves cycling the key in the ignition and can be done without any special tools.
