Restore Peak Performance to Your Cadillac
Is your 2015 or 2016 Cadillac Escalade ESV suffering from frustrating issues like a persistent check engine light, stalling, poor fuel mileage, or a no-start condition? These are common indicators of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving your luxury SUV feeling unreliable. This is a direct replacement, VIN-programmed Engine Control Module for part number 12669318, designed to restore your vehicle’s factory performance and reliability without a trip to the dealership for expensive programming.
When you order from us, you’re not just getting a part; you’re getting a complete solution. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash this module with the latest, most stable software updates directly from GM. This ensures perfect communication between the ECM and all other modules in your Escalade, providing a seamless, plug-and-play installation process. By addressing the root cause of your vehicle’s electronic issues, this module helps you get back on the road with confidence.
From the Diagnostic Bay
We had a 2015 Escalade come into the shop with a complaint of intermittent stalling and a check engine light that multiple other shops couldn’t solve. The owner had already replaced spark plugs, ignition coils, and even a fuel pump based on generic trouble codes. After hooking up our professional scan tool, we noticed communication dropouts with the engine controller. A deeper dive revealed a failing processor within the original ECM. Instead of chasing symptoms, we installed one of our VIN-programmed modules. The key relearn took less than 15 minutes, and the truck immediately started and idled perfectly. The check engine light was gone for good. It’s a classic case of how a faulty computer can mimic a dozen other mechanical problems.
Is Your 2015-2016 Escalade ESV ECM Failing?
A failing engine computer can manifest in numerous ways, often mimicking other mechanical failures. If you’re experiencing any of the following, a faulty ECM could be the culprit:
- ✔ Persistent Check Engine Light (CEL) for codes like P0601, P0606, or other internal processor faults.
- ✔ Unexplained engine stalling, stumbling, or hesitation during acceleration.
- ✔ The engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Loss of communication with the module when using a diagnostic scan tool.
- ✔ Intermittent issues that seem to have no clear cause.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for installation, flashed with the latest GM software for your specific vehicle.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. It contains critical information about the engine, transmission, and other options. We use the VIN to load the exact correct software onto the ECM, ensuring it works perfectly with your vehicle’s systems.
Is this installation difficult?
For a mechanically inclined individual, the installation is straightforward. The ECM is typically located in the left-hand front of the engine compartment. After disconnecting the battery, you simply unplug the old module and plug in the new one. In most cases, a simple security relearn procedure (turning the key on and off) is all that’s needed to start the vehicle.
How can I be sure my ECM is the actual problem?
While the symptoms listed are strong indicators of ECM failure, we always recommend a proper diagnosis by a qualified mechanic. Common diagnostic trouble codes for internal failure, such as P0601, are a definitive sign. This ensures you are replacing the correct part and not just guessing.
Will this part fix my check engine light?
If the check engine light is caused by an internal fault within your original ECM, then yes, this replacement module will resolve the issue. However, if the light is on due to other problems (like a bad sensor or catalytic converter), those issues will still need to be addressed separately.
Is any other setup required after installation?
In some GM vehicles, a Crankshaft Position Sensor Relearn may be required to clear a P1336 code. This can be done with many high-level scan tools and is a quick procedure. However, the vehicle will run and drive without it.
