Restore Your Cadillac’s Precision Performance
Is your Cadillac XLR running rough, throwing confusing check engine lights, or refusing to start? A failing Engine Control Module (ECM) can disrupt the sophisticated performance you expect from your vehicle, causing frustrating and unpredictable issues. This professionally programmed ECM is the definitive solution to restore your car’s engine to its optimal factory settings, allowing you to get back on the road with confidence and peace of mind. We program this module specifically to your vehicle’s VIN, ensuring a seamless and correct installation.
Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways. If you’re experiencing issues like a persistent Check Engine Light, poor acceleration, decreased fuel economy, erratic shifting, or a no-start condition, your ECM may be the culprit. This is especially true if your mechanic has found diagnostic trouble codes (DTCs) such as P0601, P0602, P0606, or other internal processor errors. Our 2006 Cadillac XLR ECM 12603530 is the reliable, pre-programmed fix that directly addresses these critical failures.

An Expert’s Note on VIN Programming
For a sophisticated vehicle like the Cadillac XLR, proper VIN programming isn’t just a feature—it’s a necessity. The ECM communicates with dozens of other modules, from the anti-lock brakes to the instrument cluster. An improperly programmed or generic module can create a cascade of new, hard-to-diagnose problems. We take the guesswork out of the equation by loading your car’s specific calibration files before we ship, making the installation process as simple and effective as possible for you or your technician.
Frequently Asked Questions
Is this unit ready to install right out of the box?
Yes. Because we program the 2006 Cadillac XLR ECM 12603530 to your vehicle’s VIN, it is ready for installation. In some cases, a simple automated procedure like a security or crankshaft position relearn may be required, which can be done without special tools.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is critical for us to load the correct GM software and updates for your specific car.
Will this fix my check engine light?
If your vehicle has been properly diagnosed with a faulty ECM (often indicated by codes like P0601 or P0606), this part is the correct solution. However, a check engine light can be caused by many different components, so we always recommend a full diagnosis before ordering.
What if my original part number is different?
This ECM is a direct, interchangeable replacement for several GM service numbers, including 12590032, 12602044, 12605843, and more. As long as your vehicle is listed in the compatibility chart, we will program it correctly for a perfect fit.
Is any special setup required after installation?
While the module is pre-programmed, some vehicles may require a simple security relearn procedure. This can typically be done by cycling the key in the ignition and is detailed in many online resources or service manuals. This ensures the new ECM properly syncs with your car’s anti-theft system.
