Restore Peak Performance to Your Vehicle’s Engine
The Engine Control Module (ECM), often called the engine’s brain, is the single most critical component for managing your vehicle’s performance, fuel efficiency, and emissions. It processes a constant stream of data from sensors throughout your engine to make instantaneous adjustments to fuel mixture, ignition timing, and variable valve timing. When your ECM begins to fail, it can lead to a cascade of frustrating and potentially damaging issues, from a simple check engine light to a complete no-start condition. This replacement Engine Control Module, part number 12673195, is the definitive solution to restore your vehicle’s factory-specified operation.
The Critical Advantage: VIN-Specific Programming
Simply installing a used or new ECM from another vehicle won’t work. Modern vehicles require the ECM to be programmed with software that is specific to its Vehicle Identification Number (VIN). This programming ensures all systems, from the engine and transmission to the anti-theft and emissions controls, communicate correctly. We eliminate the need for an expensive trip to the dealership by programming this module for you before it ships. Simply provide us with your vehicle’s VIN after your purchase, and our technicians will flash the unit with the latest, most stable software directly from GM. This ensures a smoother installation process and immediate restoration of proper engine function.
From the Diagnostic Bay
We recently worked on a 2015 GMC Sierra 1500 that came in with a persistent P0606 code (ECM/PCM Processor Fault) and intermittent stalling at stoplights. The owner had already replaced the spark plugs and an oxygen sensor with no success. After confirming the power and ground circuits to the ECM were solid, we identified the internal processor of the original module as the culprit. We installed one of our VIN-programmed 12673195 modules. After a quick security relearn procedure, the truck started instantly, idled smoothly, and the fault code was gone for good. The customer avoided a costly diagnostic and programming bill at the dealer and was back on the road in no time.
Your Solution for a Failing 2014-2016 CTS ECM
If you’re experiencing baffling engine issues with your Cadillac, Chevrolet, or GMC vehicle, a faulty computer could be the root cause. This module is a direct replacement for a wide range of popular GM models, including the Cadillac CTS, ATS, Escalade, Chevrolet Corvette, Silverado, and GMC Sierra. By replacing your failing unit with our pre-programmed 2014-2016 CTS ECM, you are not just buying a part; you are getting a comprehensive solution that addresses the core electronic problem and gets your vehicle running reliably again.
Is Your Vehicle Showing Signs of ECM Failure?
- ✔ Check Engine Light is illuminated with communication or processor-related codes (e.g., P0601, P0606).
- ✔ Engine stalls, hesitates, or misfires intermittently.
- ✔ Noticeable decrease in fuel economy.
- ✔ Vehicle cranks but will not start (no-start condition).
- ✔ Rough or unstable engine idle.
- ✔ Automatic transmission shifts erratically or harshly.
- ✔ Loss of communication with the diagnostic scan tool.
Guaranteed Compatibility
This module is a direct replacement for a variety of original equipment part numbers. To ensure a perfect match, please verify that your original module carries one of the following numbers: 12692067, 12676230, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, or 12669318. Providing your VIN is the most reliable way to guarantee you receive the correctly programmed part for your vehicle’s specific options and configuration.
Frequently Asked Questions
What is the process after I place my order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically add this in the notes section during checkout or reply to your order confirmation email. Once we receive your VIN, our technicians will program the module with the latest GM software specific to your vehicle. The module will then be securely packaged and shipped to you.
Is this a plug-and-play module?
Because we pre-program the module to your VIN, it is as close to plug-and-play as possible. However, on many GM vehicles, you may need to perform a security relearn procedure (also known as a CASE learn or anti-theft relearn) after installation. This procedure syncs the new ECM with your vehicle’s security system and can often be done without special tools. Instructions are widely available online for specific models.
Why is providing my VIN so important?
The VIN allows us to access the exact factory software configuration for your vehicle. This includes information about the engine, transmission, emissions equipment, and other installed options. Programming with the correct VIN-specific software is essential for the engine to run correctly and for all vehicle systems to communicate properly.
How do I know if my ECM is the actual problem?
While the symptoms listed above are common indicators of ECM failure, it’s crucial to perform a proper diagnosis. We recommend having a qualified mechanic check for diagnostic trouble codes (DTCs) and verify that the power and ground circuits to the ECM are functioning correctly before ordering. This helps ensure you are replacing the correct part.
Will this fit vehicles other than the Cadillac CTS?
Yes. This ECM is compatible with a wide range of 2014-2016 GM cars and trucks, including the Chevrolet Silverado, Corvette, Camaro, GMC Sierra, Yukon, and Cadillac Escalade, among others. Please refer to the detailed fitment list on this page and match your original part number to ensure compatibility.
