Restore Your Vehicle’s Performance and Reliability
Is your 2012 Camaro or other GM vehicle suffering from frustrating and intermittent issues? A faulty Engine Control Module (ECM) can be the hidden cause behind a wide range of problems, including a persistent check engine light, poor fuel economy, rough idling, stalling, or even a no-start condition. The ECM is the central computer of your engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it fails, the entire vehicle’s performance suffers. This replacement Engine Control Module, part number 12637106, is the definitive solution to restore your vehicle’s factory performance and operational integrity.
From the Diagnostic Bay
We once had a 2012 CTS come in that was driving the owner crazy. The car would randomly misfire and stall, but only after it was fully warmed up. The previous shop had replaced the spark plugs, coils, and even a camshaft sensor, but the problem persisted. After hours of diagnostics, we traced the issue back to the ECM. The main processor was overheating and failing under load. A simple swap with a correctly programmed module like this one had the car running perfectly in under an hour. It’s a powerful reminder that sometimes the ‘brain’ is the source of the problem, not the parts it controls.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is illuminated with various, often inconsistent, trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or erratic engine idling and poor acceleration.
- ✔ Difficulty starting the engine or a complete no-start situation.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Automatic transmission shifting issues or harsh shifts.
The Critical Advantage: VIN-Specific Programming
Don’t settle for a generic, unprogrammed module that will require an expensive trip to the dealership. Our core service is providing a 2012 Camaro Engine Control Module that is ready for installation right out of the box. Before we ship your part, our technicians will use your vehicle’s unique Vehicle Identification Number (VIN) to flash the module with the latest, most up-to-date software directly from General Motors. This critical step ensures that the ECM is perfectly matched to your vehicle’s specific configuration, including its engine, transmission, and factory options. This process eliminates compatibility conflicts and ensures all systems function exactly as the manufacturer intended.
Simple Installation Process
Physically replacing the ECM is straightforward. It is typically located in the engine compartment and can be swapped with basic hand tools. Once you provide us with your VIN during checkout, we handle all the complex programming. After installing the new module, you may need to perform a simple security relearn procedure (often called anti-theft or Passlock relearn), which can typically be done in your driveway without special tools. Instructions are widely available online for this process. This saves you hundreds of dollars in dealership labor and programming fees.

Frequently Asked Questions
What is VIN programming?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the engine control module. We use your 17-digit Vehicle Identification Number (VIN) to ensure the module we send you is an exact match for your car’s factory settings, which is essential for proper engine and transmission function.
Do I need to take my car to a dealer after installation?
No. Because we program the module to your VIN before shipping, you will not need to visit a dealer for programming. You may need to perform a simple security relearn procedure, which can be done at home and does not require a scan tool.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s VIN. We cannot ship your order until we receive and validate your VIN, as the programming is a required step.
How do I find the part number on my old ECM?
The part number is printed on a sticker on the case of your current ECM. You may need to unbolt it to see the label clearly. Matching this number with our compatible list (e.g., 12637106) is the best way to guarantee a perfect fit.
Is this a plug-and-play part?
Yes, this module is designed to be as close to plug-and-play as possible. Once we program it to your VIN, you simply install it and perform the security relearn. This avoids the complex and costly programming required by dealerships.
