Is Your Cadillac DTS Running Rough?

If you’re experiencing frustrating issues like a persistent Check Engine Light, poor engine performance, random stalling, or even a no-start condition in your 2009, 2010, or 2011 Cadillac DTS, the problem may lie with a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can cause a cascade of problems that are difficult to diagnose and can leave your luxury vehicle feeling unreliable.

Key Symptoms of a Failing DTS ECM

A faulty engine computer can manifest in numerous ways. Pay close attention if your vehicle is exhibiting any of the following signs, as they often point directly to the ECM as the root cause.

  • ✔ Persistent Check Engine Light (CEL) with various trouble codes.
  • ✔ Noticeable decrease in fuel economy.
  • ✔ Engine stalling, stuttering, or misfiring unexpectedly.
  • ✔ Difficulty starting the engine or a complete no-start situation.
  • ✔ Harsh or erratic automatic transmission shifting.
  • ✔ Loss of power and poor acceleration.
  • ✔ Communication errors with diagnostic scan tools.

Expert Pro Tip

Expert Pro Tip

Before condemning your ECM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections. A weak battery or a corroded ground wire can cause voltage fluctuations that mimic the symptoms of a failing ECM. Ensuring the electrical system is healthy is a critical first step in any diagnosis.

The Direct-Fit Solution for Your Cadillac

This Engine Control Module, part number 12628911, 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 is not just a piece of hardware; it’s a complete, ready-to-install solution. The most critical step, programming, is handled by our experts before the part ever leaves our facility. We use your vehicle’s unique 17-digit Vehicle Identification Number (VIN) to load the latest, most stable software directly from GM. This ensures that the module is perfectly calibrated for your DTS’s specific engine, transmission, and factory options.

Why VIN Programming is Crucial for Your 2009-2011 DTS Engine Module

Modern vehicles are incredibly complex. The ECM must manage dozens of systems, and the software it runs is tailored to the exact configuration of the car it was built for. Simply installing a non-programmed or incorrectly programmed module can lead to a host of new problems, from system incompatibilities to the vehicle not starting at all. Our VIN-specific programming service ensures that the 2009-2011 DTS Engine Module you receive is a true plug-and-play component. It will communicate flawlessly with the other computers in your vehicle, such as the Transmission Control Module (TCM) and Body Control Module (BCM), restoring the seamless operation you expect from a Cadillac.

Simple Ordering and Installation Process

  1. ✔ Place Your Order: Add this item to your cart and proceed to checkout.
  2. ✔ Provide Your VIN: During or after checkout, provide us with your 17-digit VIN. This is essential for the programming service.
  3. ✔ Install the Module: Installation is straightforward. Disconnect the battery, remove the old module, and install the new one. After installation, a security relearn or CASE (Crankshaft Angle Sensor Error) relearn procedure may be required, which can be performed by many qualified technicians or with certain high-end scan tools.

Broad GM Compatibility

While this is the correct part for your 2009-2011 Cadillac DTS, this versatile E38 ECM is also a direct replacement for a wide range of other GM vehicles. It is interchangeable with the following service numbers: 12636659, 12639300, 1263605, 12628993, 12625453, 12622175, 12630464, and 12678512.
