Restore Peak Performance to Your Cadillac XLR
There’s nothing more frustrating than when the sophisticated heart of your vehicle—the Engine Control Module (ECM)—begins to fail. For a precision machine like your 2006 Cadillac XLR, a faulty ECM can mean poor performance, unsettling warning lights, or even a car that won’t start. This isn’t just an inconvenience; it’s a barrier to enjoying the drive. We offer the definitive solution: a professionally programmed Engine Control Module that restores your vehicle’s power, efficiency, and reliability, getting you back on the road with confidence.
Common Symptoms of a Failing ECM & Your Direct Solution

Expert Insight: The Critical Role of VIN Programming
In modern vehicles, the ECM is the central nervous system. It doesn’t just manage the engine; it integrates with the transmission, ABS, and crucial anti-theft systems (like GM’s VATS/Passlock). A generic, non-programmed module simply won’t work—the car won’t start. That’s why our process of flashing the Programmed 2006 Cadillac XLR ECM 12603530 to your specific VIN is non-negotiable. It ensures every component recognizes the new ECM, creating a seamless, secure, and fully functional repair, just as the factory intended.
Frequently Asked Questions
What do I need to do after I purchase this ECM?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can typically add this as a note during checkout or send it to us in a message referencing your order number.
Is this part difficult to install?
For most individuals with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old ECM, removing a few mounting bolts, and then installing the new unit in reverse order. It’s a true plug-and-play process with no programming required on your end.
Will this fix my car’s specific problem?
This ECM will resolve any issues directly caused by a faulty engine computer. While it corrects a wide range of problems, including many common DTCs, we always recommend having a proper diagnosis performed to confirm the ECM is the source of your issue before ordering.
Is any additional programming required after installation?
In most cases, no. The unit is pre-programmed for your vehicle. Some GM vehicles may require a simple security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools and instructions are widely available online. However, for the vast majority of installations, you can simply plug it in and start the vehicle.
Which part number will I receive?
You will receive an ECM that is 100% compatible with your vehicle. The part number on the sticker may be any one of the interchangeable service numbers listed (e.g., 12603530, 12607096, etc.), but it will be programmed with the correct software for your VIN and function identically to your original.
How does the one-year warranty work?
This unit is backed by our one-year replacement warranty. If the module fails within one year of the purchase date, we will provide a replacement unit. This gives you confidence and security in your repair.
