Is your 2004-2006 Cadillac SRX suffering from perplexing issues like stalling, rough idling, a persistent check engine light, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions control. When it fails, the entire system can become unreliable. This listing offers a direct, cost-effective solution: a genuine, used OEM ECM, part number 19260507, professionally programmed to your vehicle’s specific VIN.
Don’t let a faulty computer keep your luxury SUV off the road. We take the guesswork out of the repair by providing a module that is ready for installation. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our technicians will flash the unit with the latest GM software updates specific to your SRX. This ensures seamless communication with your vehicle’s other modules and restores the precise performance and efficiency you expect from your Cadillac.
Diagnosing a Failing 2004-2006 SRX ECM
A failing engine computer can manifest in numerous ways, often mimicking other sensor or component failures. If you’ve replaced sensors and checked wiring harnesses to no avail, the ECM itself is the likely culprit. This module is the central command for your 3.6L engine, and its failure can lead to frustrating and unpredictable behavior. Replacing it with a properly programmed unit is the definitive fix for these electronic issues.
From the Diagnostic Bay
We had a 2005 SRX come into the shop with an intermittent no-start and a random cylinder misfire code that kept jumping from one cylinder to another. The owner had already replaced spark plugs, ignition coils, and even a camshaft position sensor based on previous advice. The problem persisted. After hooking up our diagnostic scanner and monitoring live data, we noticed the injector pulse width signals were erratic during cranking. We suspected the ECM’s driver circuits were failing. Instead of spending more hours on diagnostics, we swapped in a pre-programmed ECM like this one. The SRX fired up on the first try and ran perfectly smooth. It’s a great reminder that when you’re chasing ghosts in the electrical system, sometimes the problem lies with the ghost-master itself: the ECM.
Common Symptoms of a Faulty ECM
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine stalls unexpectedly or struggles to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or erratic engine idling.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is essential for programming the ECM. It contains specific information about your car’s options, engine, transmission, and security system. We flash the module with the correct GM software for your exact vehicle, ensuring it works perfectly upon installation.
Is this a plug-and-play part?
Because we program the ECM to your VIN before shipping, it is designed to be as close to plug-and-play as possible. However, some vehicles may require a security relearn procedure (often called a key relearn or anti-theft relearn) after installation, which can typically be done without special tools. Instructions are widely available online for this simple process.
Where is the ECM located on my 2004-2006 SRX?
On the 2004-2006 Cadillac SRX with the 3.6L engine, the Engine Control Module is located in the right-hand (passenger side) front of the engine compartment. Always disconnect the battery before attempting to remove or install any electronic modules.
This is a used part. How can I be sure it works?
This ECM is a genuine OEM part sourced from a functioning, salvaged vehicle. While it is used, OEM components are built to high standards. We test the hardware and then program it with fresh, updated software, making it a reliable and economical alternative to a brand-new dealership part.
What if my original part number is different?
