2004-2006 SRX ECM Engine Control Module 19260507 Programmed

Restore Peak Performance to Your Vehicle

Is your 2004-2006 Cadillac SRX, CTS, or other compatible GM vehicle experiencing perplexing issues like stalling, poor fuel economy, or a persistent Check Engine Light? The Engine Control Module (ECM), the central computer of your vehicle, is often the culprit behind these frustrating problems. It governs everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the entire system can become unreliable. This listing offers a direct, reliable replacement solution: a genuine, used ECM (part number 19260507, interchangeable with 12592124, 12581144, and 12588472) that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN).

The Importance of a Programmed ECM

Simply swapping an ECM from another vehicle will not work. Modern vehicles have sophisticated anti-theft systems and vehicle-specific parameters that are stored within the ECM. Our process eliminates the need for expensive dealership programming or specialized tools. We flash the module with the latest GM software updates using your VIN, ensuring it communicates perfectly with your vehicle’s other computers right out of the box. This makes for a straightforward installation, getting you back on the road faster and with less hassle.

Is This the Right Part for Your 2004-2006 SRX ECM?

This module is the correct replacement for a wide range of GM vehicles equipped with the 3.6L engine. It is critical to match the part number or service number from your original module. This unit is a direct replacement for service numbers 12581144, 12588472, 12592124, and 19260507. It is located in the right-hand front of the engine compartment on the SRX and CTS models, and in the lower air cleaner housing on Buick Allure and LaCrosse models. Please verify the location and part number on your original unit before ordering.

Common Symptoms of a Failing ECM

• ✔ Check Engine Light: The most common indicator, often with communication-related or internal processor fault codes (e.g., P0601, P0606).
• ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM fails to properly control ignition and fuel.
• ✔ No-Start Condition: The vehicle may crank but refuse to start if the ECM is not activating the fuel pump or ignition coils.
• ✔ Poor Fuel Economy: Incorrect fuel mixture calculations can lead to a sudden and significant drop in MPG.
• ✔ Transmission Shifting Problems: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifting. A faulty ECM can cause harsh shifts, delayed engagement, or getting stuck in one gear.
• ✔ Intermittent Electrical Issues: Seemingly unrelated electrical problems can sometimes be traced back to a failing main computer.

Simple Ordering and Installation Process

1. ✔ Confirm Fitment: Match your vehicle, year, and engine to the fitment list and verify your original part number matches one of the compatible numbers provided.
2. ✔ Place Your Order: Complete your purchase through our secure checkout.
