Restore Peak Performance to Your Cadillac
Is your 2015-2016 Cadillac Escalade ESV experiencing perplexing issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel efficiency? These are common indicators that the heart of your engine’s management system, the Engine Control Module (ECM), may be failing. As the central computer, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifts and emissions control. When it falters, the entire vehicle’s performance and reliability are compromised. This replacement Engine Control Module, part number 12673195, is the definitive solution to restore your vehicle’s factory performance and dependability.
We take the guesswork and hassle out of the repair process. Unlike a generic module from a parts store or a salvage yard, this unit is professionally programmed specifically for your vehicle using your unique Vehicle Identification Number (VIN). This critical step ensures that the module communicates flawlessly with all other systems in your Escalade, integrating perfectly as the original did. We flash it with the latest, most stable software updates directly from GM, which often resolve underlying issues and improve overall vehicle operation. This is a direct-fit, plug-and-play solution designed to get you back on the road with confidence.
From the Diagnostic Bay
We had a 2016 Escalade ESV come into the shop with a complaint of intermittent stalling at stoplights and a check engine light that three different shops couldn’t permanently fix. The codes were all over the place—misfires, communication errors, and a vague processor fault code (P0606). After checking the wiring and major sensors, we focused on the ECM. The original module was failing internally, causing erratic signals. We installed one of our VIN-programmed modules, flashed with the latest GM calibration. After a quick security relearn procedure, the vehicle started and ran perfectly. The check engine light was gone, the stalling issue was resolved, and the owner was thrilled to have their luxury SUV running smoothly again. It’s a perfect example of how a correctly programmed module is the only way to solve complex electronic issues.
Diagnosing a Faulty 2015-2016 Escalade ESV ECM
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following symptoms, your ECM is a likely culprit. This module is the direct solution for these common problems.
- ✔ Persistent Check Engine Light: The most common sign, often with codes related to processor faults (e.g., P0601-P0606), sensor circuits, or communication errors.
- ✔ Engine Performance Issues: Noticeable loss of power, hesitation during acceleration, rough running, or random engine misfires.
- ✔ Stalling or No-Start Condition: The engine may stall unexpectedly while driving or refuse to start at all, even with a good battery and starter.
- ✔ Poor Fuel Economy: An inefficiently running engine, managed by a faulty ECM, will consume more fuel than usual.
- ✔ Erratic Transmission Behavior: The ECM works with the Transmission Control Module (TCM) to manage shifting. A bad ECM can cause harsh shifts, delayed engagement, or the transmission getting stuck in one gear.
- ✔ Communication Failures: Your diagnostic scan tool may be unable to communicate with the engine computer, indicating a total failure.

Frequently Asked Questions
Do I need to get this ECM programmed?
No. This module comes fully programmed to your vehicle’s specific VIN before it is shipped. It is ready for installation upon arrival, saving you a trip to the dealership.
Where is the ECM located on my 2015-2016 Escalade ESV?
The Engine Control Module is typically located in the engine bay, on the left-hand (driver’s side) front of the engine compartment.
What is a VIN and why do you need it?
The VIN, or Vehicle Identification Number, is a unique 17-digit code for your specific vehicle. We use it to load the exact software, security information, and calibrations your Escalade ESV requires for all systems to function correctly.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty ECM, this replacement part will solve the problem. However, it’s always recommended to have a proper diagnosis to ensure other components like sensors or wiring are not the root cause.
Is any additional work required after installation?
In many cases, a simple security relearn procedure may be required after installation. This can often be done without special tools and involves a sequence of key turns. Instructions are readily available online, or any professional mechanic can perform it in minutes.
How do I provide my VIN?
You can add your 17-digit VIN in the notes section during checkout. If you forget, we will contact you via email after your purchase to request it before we program and ship your module.
