Is Your Cadillac DTS Running Rough?
If your 2006 Cadillac DTS is experiencing perplexing issues like a persistent check engine light, erratic engine behavior, poor fuel economy, or even a no-start condition, the root cause could be a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the symptoms can be widespread and frustrating, making a reliable replacement essential.
This genuine GM Engine Control Module, part number 19210737, is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork and hassle out of the replacement process. Unlike a generic part from a local store, this module comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This ensures perfect communication with all other onboard systems, just as the factory intended.
Diagnosing a Faulty 2006 DTS Engine Module
Identifying a failing ECM can be tricky, as its symptoms often overlap with other component failures. However, if you’re experiencing a combination of the following issues, your engine module is a likely culprit. A proper diagnosis with a professional scan tool is always recommended, but these signs are strong indicators that your 2006 DTS Engine Module needs attention.
Common Symptoms of ECM Failure
- ✔ Check Engine Light: The check engine light is illuminated, often with communication-related error codes (U-codes) or multiple, seemingly unrelated sensor codes.
- ✔ Engine Performance Problems: You may notice rough idling, stalling, hesitation during acceleration, or a significant loss of power.
- ✔ Poor Fuel Economy: An incorrect air/fuel mixture managed by a faulty ECM can cause a sudden and dramatic decrease in your vehicle’s gas mileage.
- ✔ Starting Issues: The vehicle may crank but refuse to start, or it may fail to start intermittently for no apparent reason.
- ✔ Transmission Shifting Problems: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifting. A bad ECM can cause harsh shifts, delayed engagement, or the transmission getting stuck in one gear (limp mode).
- ✔ Cooling Fans Not Working: The ECM often controls the engine’s cooling fans. If they fail to turn on, it can lead to overheating.

Frequently Asked Questions
Do I need to have this module programmed?
No. This module comes fully programmed to your vehicle’s VIN before it is shipped. Simply provide your VIN during or after checkout, and we handle the rest. It will be ready to install upon arrival.
What is a VIN and why is it required?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. It contains information about the manufacturer, model, year, and factory-installed options. We use the VIN to load the exact software and calibrations your vehicle needs for optimal performance and compatibility.
Is any other procedure needed after installation?
In many cases, the module is a simple plug-and-play installation. However, some GM vehicles may require a security relearn procedure (also known as a Passlock or anti-theft relearn) to allow the vehicle to start. This procedure can typically be done without special tools and instructions can be easily found online or in your owner’s manual. A CASE (Crankshaft Angle Sensor Error) relearn may also be needed, which requires a compatible scan tool.
How do I confirm this is the right part for my car?
This module fits a 2006 Cadillac DTS and many other GM vehicles listed in the compatibility chart. The best way to confirm is to match the service number from your existing module to one of the numbers listed (e.g., 19210737, 12607096). If you are unsure, please contact us with your VIN, and we can verify fitment for you.
Will this fix my check engine light?
If the check engine light and other symptoms are being caused by a faulty ECM, then yes, this replacement part will resolve those issues. It is crucial to have your vehicle properly diagnosed to ensure the ECM is the point of failure before ordering.
