Restore Peak Performance to Your GM Vehicle
Is your Chevrolet, GMC, or Cadillac suffering from frustrating and difficult-to-diagnose issues? A faulty Engine Control Module (ECM) is often the hidden culprit behind check engine lights, poor fuel economy, stalling, or a no-start condition. This genuine GM Engine Control Module, part number 12672537, is the definitive solution to restore your vehicle’s factory performance, drivability, and reliability. It serves as the ‘brain’ of your engine, precisely managing fuel injection, ignition timing, emissions systems, and dozens of other critical parameters. When it fails, the entire system can become unstable. This replacement part is the first step to getting your vehicle back on the road with confidence.
From the Diagnostic Bay
We had a 2016 Silverado 1500 come into the shop with a persistent P0606 (Internal Control Module Processor Error) code that just wouldn’t stay cleared. The owner had already replaced the throttle body and a few sensors, chasing what he thought was a simple component failure. After hooking up our diagnostic scanner and monitoring live data, we saw erratic readings from multiple sensors that made no sense together. This is a classic sign that the central processor—the ECM—is failing. Instead of continuing to replace good parts, we installed a VIN-programmed ECM just like this one. After the quick security relearn, the truck started right up, all data streams stabilized, and the code never returned. It saved the customer hundreds in unnecessary parts and labor by correctly identifying the root cause.
Is Your Vehicle Exhibiting These Symptoms?
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty 2016 Camaro Engine Module or a compatible vehicle’s ECM could be the cause:
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ A complete no-start condition where the engine cranks but won’t fire up.
- ✔ Noticeable decrease in fuel efficiency for no apparent reason.
- ✔ Transmission shifting erratically or harshly.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Multiple, unrelated trouble codes stored in the system.
The Plug-and-Play Solution: Programmed to Your VIN
Replacing an ECM isn’t just about swapping hardware. Modern vehicles require the module to be programmed specifically to the vehicle’s Vehicle Identification Number (VIN). This process ensures all factory-installed options, security systems, and emissions controls function correctly. We handle this critical step for you. Before we ship your part, our technicians will flash it with the latest, most up-to-date GM software for your exact VIN. This eliminates the need for an expensive trip to the dealership for programming. Once installed, you will only need to perform a simple security relearn procedure (often called a key relearn), which can typically be done in your own driveway without special tools.
Direct Replacement for Multiple Part Numbers
This module is a direct, interchangeable replacement for a wide range of original part numbers. If your old module has any of the following numbers, this part is a confirmed fit: 12692067, 12676230, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, and 12669318.

Frequently Asked Questions
Do I need to have this module programmed?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and we will flash the module with the latest GM software specific to your vehicle.
What is a ‘security relearn’ procedure?
A security relearn, or key relearn, is a simple procedure required on most GM vehicles to sync the new ECM with your vehicle’s anti-theft system and keys. It typically involves a sequence of turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this two more times. Instructions are widely available online for your specific model and can be done without any special tools.
Is this a brand new part?
This is a high-quality, OEM-grade used part that has been thoroughly inspected, tested, and guaranteed to be fully functional. It is then professionally programmed to your VIN to ensure it performs just like a new unit from the factory.
Where is the VIN located on my vehicle?
You can find your 17-digit Vehicle Identification Number (VIN) on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my car’s problem for sure?
While this ECM is the correct solution for the symptoms listed, proper vehicle diagnosis is essential. We recommend confirming the ECM is the faulty component before purchasing. This part is guaranteed to be a functional, correctly programmed module for the vehicles listed.
