Restore Your Cadillac’s Precision Performance

Is your 2008-2009 Cadillac XLR suffering from frustrating and hard-to-diagnose issues? A faulty Engine Control Module (ECM) can manifest as a check engine light that won’t go away, rough idling, stalling, poor fuel economy, or even a complete no-start condition. Don’t let a failing computer compromise the sophisticated performance of your luxury roadster. This genuine GM Engine Control Module is the definitive solution, arriving at your door fully programmed and ready for a straightforward installation.

Expert Insight: The Brain of Your Vehicle

The ECM is more than just a component; it’s the central nervous system of your Cadillac’s powertrain. It makes thousands of calculations per second, managing everything from fuel injection and ignition timing to emissions controls and transmission logic. In a sophisticated vehicle like the XLR, proper programming isn’t just a suggestion—it’s critical. An improperly matched module can cause a cascade of issues. Our VIN-specific programming ensures this new brain integrates perfectly with your car’s existing systems, restoring the precise, responsive driving experience you expect.

Frequently Asked Questions

How do I provide my VIN?

After you complete your purchase, simply reply to your order confirmation email with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming process is specific to your car.

Is any additional programming required after installation?

In most cases, no. This 2008-2009 Cadillac XLR Engine Control Module is designed to be a plug-and-play solution. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for this simple procedure.

My original part number is not 12602044. Will this still work?

Yes. This ECM is a direct replacement for all the service numbers listed in the description, including 12590032, 12603530, 12605843, and others. As long as your vehicle is listed in the compatibility chart, this module will function correctly once programmed to your VIN.

Is this a used part?

This is a high-quality, tested OEM part that has been meticulously inspected and prepared for programming. It provides the same form, fit, and function as a new dealer part without the excessive cost.

What does the one-year warranty cover?

Our one-year replacement warranty covers the part itself. If the module fails within one year of the purchase date, we will provide a replacement unit. Please contact us for complete details and procedures.
