Is Your GM Vehicle Stalling, Misfiring, or Refusing to Start?
A faulty Engine Control Module (ECM) is often the hidden culprit behind a host of frustrating and difficult-to-diagnose engine problems. If your 2006-2007 Cobalt, 2006 Malibu, or 2006-2007 Saturn Ion is experiencing erratic behavior, poor performance, or has an illuminated Check Engine Light, the very brain of your engine’s operation may be failing. This genuine, used OEM ECM, part number 12615197 (also interchangeable with 12597520 and 12579132), is the reliable and cost-effective solution to restore your vehicle’s performance and dependability.
The Critical Importance of Correct Programming
Replacing an ECM isn’t a simple swap. The module must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM factory software. Without this crucial step, the module will not communicate correctly with the other systems in your car, leading to a no-start condition or other severe issues. Our service eliminates this expensive and time-consuming hurdle. We flash the module for you before it ships, making the installation process as straightforward as possible.
From the Diagnostic Bay
We had a 2007 Cobalt SS come into the shop with a maddeningly intermittent issue. The owner complained of the car suddenly losing power and stalling at stoplights, but with no consistent diagnostic codes. We checked the fuel pump, sensors, and wiring, but everything seemed fine. After hours of diagnostics, we monitored the live data from the ECM and noticed the injector pulse width would randomly drop to zero right before a stall. It was a classic case of an internal ECM fault that wouldn’t throw a specific code. We replaced it with a pre-programmed unit just like this one, and the car ran perfectly. It saved the owner from replacing countless other parts in a frustrating guessing game.

Frequently Asked Questions
Do I need to have this ECM programmed?
No. The main benefit of our service is that we program the module for you before shipping. You just need to provide your vehicle’s 17-digit VIN during or after checkout. It will arrive ready to be installed.
Is this a new part?
No, this is a genuine OEM part that has been carefully removed from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped.
What is a VIN and why do you need it?
The VIN, or Vehicle Identification Number, is a unique 17-digit code for your specific car. It contains information about the manufacturer, model, year, and factory-installed options. We use the VIN to load the exact software and calibrations your vehicle requires to run properly.
Will I need to do anything after installing the module?
In most cases, you will need to perform a simple security relearn procedure, also known as a VATS relearn. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This syncs the new ECM with your vehicle’s anti-theft system. Instructions are readily available online for this simple process.
Where is the ECM located on my 2007 Cobalt?
On the 2006-2007 Chevrolet Cobalt, the ECM is typically located in the engine compartment on the driver’s side, near the fuse box and battery.
