Is Your Escalade Experiencing Frustrating Engine Problems?
If your 2015 or 2016 Cadillac Escalade is suffering from issues like a persistent Check Engine Light, rough idling, stalling, poor fuel economy, or even a no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, orchestrating everything from fuel injection and ignition timing to transmission shifts and emissions control. When it begins to fail, it can create a cascade of problems that are often difficult to diagnose, leading to costly and unnecessary repairs.
Don’t let a faulty computer keep your luxury SUV off the road. This is a genuine GM Engine Control Module (Part #12672963) that serves as a direct-fit, reliable solution. The best part? We eliminate the most significant hurdle of ECM replacement: programming. We flash the module with the latest official GM software, specifically calibrated to your Escalade’s unique Vehicle Identification Number (VIN) before it ever leaves our facility. This means you receive a part that is ready for installation, saving you a trip to the dealership and hundreds of dollars in programming fees.
From the Diagnostic Bay
We had a 2015 Escalade towed in that had every mechanic who looked at it stumped. It had an intermittent no-start condition with no clear codes pointing to a single failure. The owner had already replaced the battery, alternator, and starter. After hours of tracing wires and checking grounds, we hooked up our high-level diagnostic tool and monitored the ECM’s data stream during a crank attempt. We noticed the 5-volt reference signal, which powers critical sensors, was dropping out intermittently. This pointed directly to an internal failure in the ECM. We installed a VIN-programmed module just like this one, performed the security relearn, and the truck fired up instantly. The owner was thrilled to have his vehicle back and running reliably after weeks of uncertainty.

Replacing an ECM has traditionally been a job reserved for dealerships due to the complex programming required. Our service changes that. By providing us with your VIN during checkout, you empower our technicians to load the precise software your vehicle needs. This ensures all factory settings, from engine parameters to anti-theft systems, are correctly configured. When you receive the module, the primary task is the physical installation and a straightforward Security Relearn Procedure, which you can typically perform yourself in your driveway. This process syncs the new ECM with your vehicle’s security system and keys.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This saves you the time, cost, and hassle of a dealership visit for programming.
What is the Security Relearn Procedure?
The Security Relearn, or anti-theft relearn, is a simple procedure that syncs the new ECM with your vehicle’s existing keys and security system. It typically involves a series of key turns and waiting periods and does not require any special tools. We include instructions to guide you through this final step.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield on the driver’s side), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a brand new part?
This is a high-quality, genuine OEM part that has been meticulously inspected and prepared to ensure it meets or exceeds original factory specifications. It is loaded with the latest GM-certified software for your vehicle.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty ECM, this part will resolve the issue. However, it is always recommended to have your vehicle properly diagnosed to confirm the ECM is the root cause of the problem before ordering.
