When the sophisticated engine in your Cadillac Escalade, GMC Sierra, or Chevrolet Tahoe begins to act erratically, the root cause is often the very component that controls it all: the Engine Control Module. A failing ECM can lead to frustrating and debilitating issues, leaving your high-performance vehicle running poorly or not at all. This replacement Engine Control Module is the definitive solution, arriving at your door professionally programmed with the latest GM software updates tailored specifically to your vehicle’s VIN.
Common Symptoms & Your Solution
If you’re experiencing issues like a persistent Check Engine Light, engine stalling, rough idling, poor fuel economy, or a complete no-start condition, a faulty ECM is a likely culprit.

Expert Insight from the Technician’s Bench
As a technician with over two decades of experience, I’ve seen countless drivers chase expensive sensor and component replacements when the real issue was the ECM. In modern GM vehicles, the ECM is the central hub of a complex data network. Simply installing a used, non-programmed module is a recipe for disasterโit can cause communication errors, immobilizer problems, and even damage other electronics. Our process of pre-programming the module to your specific VIN is not just a convenience; it’s a critical step that mimics the dealership’s own procedure, ensuring the computer integrates seamlessly, just as the original did. This is the key to a lasting, correct repair for your vehicle.
By providing us with your VIN upon purchase, you ensure that the programmed 2017 Escalade ECM you receive is ready for the final installation steps. This attention to detail is what separates a quick fix from a proper, long-term solution.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) contains critical information about your vehicle’s specific options, engine type, transmission, and emissions equipment. We use the VIN to load the exact, correct GM factory software and calibrations onto the ECM, ensuring it works perfectly with your vehicle.
What is a ‘theft relearn’ and will I need to do it?
The vehicle’s anti-theft system (Pass-Key/Pass-Lock) links your key, ignition, and ECM. When you replace the ECM, this link is broken. A theft relearn procedure re-establishes this connection. In many cases, if the vehicle does not start after installation, this procedure will be required. It must be performed by a technician with access to GM’s official programming system (Tis2web/Techline Connect).
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, the critical part is the electronic integration. After installation, procedures like the theft relearn, crankshaft variation relearn, or injector setup may be necessary. We strongly recommend installation by a qualified professional technician familiar with GM vehicles.
Will this fix my specific problem?
This ECM will resolve issues directly caused by a failing engine computer, such as internal processor faults (e.g., DTC P0606). While it is a common failure point, it’s essential to have a proper diagnosis performed by a qualified mechanic to confirm the ECM is the source of your vehicle’s symptoms before ordering a programmed 2017 Escalade ECM.
What other part numbers does this ECM replace?
This module is a direct replacement for several part numbers, including 12692068, 12704476, 12686382, 12674052, 12674472, and 12678815. Please check the fitment list to confirm it matches your specific make and model.
