Restore Peak Performance to Your Vehicle
Is your Chevrolet Cobalt, Malibu, HHR, or other GM vehicle suffering from strange and frustrating issues? A faulty Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), is often the culprit behind problems like a persistent check engine light, poor engine performance, random stalling, or even a no-start condition. The ECM is the central computer of your vehicle’s engine management system, controlling everything from fuel mixture and ignition timing to transmission shifting and emissions. When it fails, the entire vehicle’s performance and reliability are compromised.
This replacement ECM, compatible with service number 12612397 and others, is the definitive solution to get your car back on the road. We take the guesswork and hassle out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures complete compatibility with your car’s factory settings, security system, and options, making the installation process as seamless as possible.
From the Diagnostic Bay
We recently had a 2008 Chevy Cobalt in the shop that was driving its owner crazy. It had a random misfire that wouldn’t set a specific cylinder code, the transmission would occasionally shift harshly, and the cooling fans would run constantly. The owner had already replaced spark plugs, coils, and even a MAP sensor with no luck. After hooking up our professional scan tool, we noticed communication dropouts with the engine module. After confirming all power and ground circuits to the computer were solid, we identified an internal failure in the ECM. A direct replacement, pre-programmed 2007-2010 Cobalt ECM like this one, was the answer. Once installed and a quick security relearn was performed, all the ghost-like issues vanished. The car ran smoother than it had in years.

We load the latest GM-certified software and calibrations based on your VIN, ensuring your engine runs efficiently and meets emission standards. This unit is a reliable and cost-effective way to solve complex electronic issues and restore your vehicle’s drivability.
Common Symptoms of a Failing GM ECM
- ✔ Persistent Check Engine Light (CEL) with codes related to processor faults (e.g., P0601, P0606).
- ✔ Engine stalling, stumbling, or running rough for no apparent reason.
- ✔ A noticeable decrease in fuel economy.
- ✔ The engine cranks but refuses to start.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Loss of communication with the OBD-II port, preventing diagnostics.
- ✔ Other seemingly unrelated electrical issues, as the ECM communicates with many other modules.
This module is a verified fit for dozens of models. While it’s a perfect 2007-2010 Cobalt ECM, it also fits vehicles like the Pontiac G6, Saturn Aura, Chevy HHR, and even trucks like the Silverado 1500 with the 4.3L engine. Please verify your original service number against our provided list (12612397, 12597125, 12629019, etc.) to ensure perfect compatibility.
Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module to your car’s specific VIN before we ship it to you. This saves you the time, cost, and hassle of a dealership visit.
Is this installation difficult?
For most models, the physical installation is straightforward, typically involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. However, after installation, you will likely need to perform a security relearn procedure (often called a Passlock or anti-theft relearn), which pairs the new ECM to your vehicle’s keys. This procedure can usually be done without special tools and instructions are widely available online for your specific model.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for the part to function in your vehicle.
What if my original part number is not 12612397?
This ECM is a direct replacement for several service numbers. Please check the list in the description, which includes 12597125, 12629019, 12635902, and others. As long as your original number is on that list, this module will work for your vehicle.
Will this fix my car’s specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, it’s crucial to have your vehicle properly diagnosed. Ensure that wiring, sensors, and other related components have been checked to confirm the ECM is the source of the problem.
