Is your Cadillac CTS, Buick Allure/LaCrosse, or SRX suffering from perplexing engine issues? A faulty Engine Control Module (ECM) is often the culprit behind problems like a persistent check engine light, poor fuel economy, stalling, or even a no-start condition. The ECM is the central computer of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions control. When it fails, the entire system’s performance and reliability are compromised. This genuine OEM Engine Control Module, part number 19260507, is the definitive solution to restore your vehicle’s factory performance and dependability.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and high dealership costs out of the equation by programming the module specifically for your vehicle using your VIN. Before we ship it, our technicians will flash it with the latest, most stable software updates from General Motors. This ensures optimal performance, fuel efficiency, and compatibility with your vehicle’s specific systems. Simply provide your VIN at checkout, and we handle the complex programming for you.

Why Choose Our Pre-Programmed 2004-2007 CTS ECM?

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler and saves you from expensive dealership programming fees.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship the part until we have this information to complete the programming.
Is this a new part?
No, this is a high-quality, tested, and fully functional used OEM part that has been sourced from a salvaged vehicle. This ensures a perfect fit and reliable operation at a fraction of the cost of a new unit.
Where is the ECM located on my 2005 Cadillac CTS?
On the 2004-2007 Cadillac CTS, the ECM is typically located in the engine compartment on the right-hand (passenger) side. Always disconnect the battery before attempting to remove or install any electronic modules.
Will this part fix my car’s problem?
This module will resolve any issues directly caused by a faulty ECM. However, it is crucial that your vehicle has been properly diagnosed. This part will not fix problems related to other faulty components like sensors, wiring, or mechanical parts.
What is a security relearn procedure?
A security relearn, or anti-theft relearn, is a simple procedure that syncs the new ECM with your car’s existing keys and security system. For many GM vehicles, this involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating the cycle three times.
