Restore Peak Performance to Your GM Vehicle
Is your Cadillac, Chevrolet, or GMC suffering from perplexing issues like poor fuel economy, intermittent stalling, or a persistent check engine light? The Engine Control Module (ECM), often called the vehicle’s brain, is responsible for managing every critical aspect of engine performance. When it fails, it can cause a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs. This genuine GM Engine Control Module, part number 12676230, is the definitive solution to restore your vehicle’s factory performance, reliability, and efficiency.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and additional expense out of the equation by programming the module specifically for your vehicle using your VIN. This ensures that all factory settings, security protocols, and performance parameters are perfectly matched to your car or truck’s original specifications. It arrives flashed with the latest, most stable software updates from GM, often correcting underlying issues you didn’t even know were present.
From the Diagnostic Bay
We had a 2015 Silverado 1500 come into the shop with a list of complaints from the owner. It was running rough at idle, had hesitation on acceleration, and the transmission was shifting erratically. The owner had already replaced the mass airflow sensor and a couple of O2 sensors at another shop with no improvement. After hooking up our diagnostic scanner, we noticed strange voltage readings from multiple sensors that didn’t make sense together. Instead of chasing ghosts and replacing more parts, we focused on the central hub: the ECM. A failing ECM can send out incorrect signals, making good sensors appear faulty. After installing a VIN-programmed ECM like this one, all the phantom sensor codes vanished, the engine smoothed out, and the transmission shifted perfectly. It saved the customer hundreds in further diagnostic time and parts.
Common Symptoms of a Failing ECM
If you’re experiencing any of the following issues, a faulty ECM could be the culprit. Replacing it with a properly programmed unit is often the most direct path to a lasting repair.
- ✔ Check Engine Light is on with various, often unrelated, trouble codes (P-codes).
- ✔ Engine stalling or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ The vehicle won’t start, but the battery and starter are good.
- ✔ Poor engine performance, including hesitation or lack of power.
- ✔ Automatic transmission shifting issues or harsh shifts.
- ✔ Problems with communication between different vehicle modules.

Frequently Asked Questions
Do I need to do any additional programming after installation?
No. We program the ECM to your vehicle’s VIN before shipping. In most cases, it is a plug-and-play installation. However, some GM vehicles may require a simple security relearn procedure (also known as a key relearn or anti-theft relearn) which can typically be done without any special tools. Instructions are readily available online for this 10-30 minute process.
How do I provide my VIN?
After you complete your purchase, you can either add your VIN to the order notes or simply reply to your order confirmation email with the 17-digit VIN. We cannot ship the part until we receive this information.
Is this a new or used part?
This is a high-quality, tested, and verified OEM part. Each module undergoes a rigorous inspection and testing process to ensure it meets or exceeds original factory specifications before being programmed and shipped.
What if my original part number is not listed but my vehicle is?
GM often uses multiple part numbers for the same component. The part numbers we’ve listed (12692067, 12676230, 12656993, etc.) are all interchangeable. As long as your vehicle model and year are on our compatibility list, this module will work once programmed to your VIN.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty ECM, then this part is the correct solution. It is crucial to have a proper diagnosis performed to confirm the ECM is the root cause of the issue before ordering.
