Is Your Vehicle Plagued by Unexplained Issues?
If your Cadillac, GMC, or Chevrolet is experiencing frustrating problems like a persistent check engine light, erratic engine performance, stalling, or a complete no-start condition, a failing Engine Control Module (ECM) is often the culprit. The ECM is the brain of your vehicle’s engine, and when it fails, it can cause a cascade of issues that are difficult to diagnose. Don’t let a faulty computer keep you off the road. This professionally programmed module is the definitive solution to restore your vehicle’s performance and reliability.
Common Symptoms & Your Solution
A failing ECM can manifest in various ways. You might be seeing diagnostic trouble codes (DTCs) like P0606 (ECM/PCM Processor Fault) or U0100 (Lost Communication With ECM/PCM). Or you may be experiencing symptoms without a clear code, such as:
- Poor acceleration or hesitation
- Reduced fuel economy
- Transmission shifting problems
- Intermittent or total failure to start
- Warning lights on the dashboard that won’t go away

Expert Insight: The Critical Role of VIN Programming
Many people are tempted to buy a used ECM from a salvage yard, thinking it’s a simple swap. However, a modern vehicle’s computer is intricately tied to its specific options, security system, and other modules. Our VIN-specific programming is not just a convenienceโit’s essential. We ensure the software on your new 2017 Cadillac XTS engine control module precisely matches your vehicle’s factory build. This crucial step prevents a host of potential issues, from incorrect transmission behavior to immobilizer lockouts, saving you hours of diagnostic headaches and additional costs down the line.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact software and calibrations your specific vehicle requires. This includes parameters for your engine, transmission, and all factory-installed options. It is the only way to guarantee the module will work correctly upon installation.
What is a “theft relearn” and is it difficult?
The Vehicle Theft Deterrent (VTD) system links your ECM to your keys. When the ECM is replaced, this link must be re-established. This “theft relearn” procedure requires a professional scan tool with access to GM’s programming system (Tis2web/Techline Connect). While the procedure itself is quick, it must be performed by a qualified technician or a shop with the correct equipment.
Will this ECM fix my specific problem?
This module will resolve issues directly caused by a faulty ECM. While it is the solution for many common symptoms like processor fault codes and no-start conditions, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the point of failure before ordering.
Is this a simple plug-and-play installation?
The physical installation is straightforwardโit unbolts and unplugs. However, due to the required VTD relearn and potential for other setup procedures (like crankshaft variation or injector flow rates), this is not a simple plug-and-play part. Post-installation electronic setup by a professional is required for the vehicle to start and run correctly.
What other part numbers does this module replace?
This ECM is a direct replacement for a range of GM part numbers, including 12692068, 12704476, 12686382, 12674052, 12674472, and 12678815. This ensures wide compatibility across many GM trucks and luxury vehicles.
