An Expert’s Note on VIN Programming
For a sophisticated vehicle like the Cadillac XLR, VIN-specific programming is not just a convenience—it’s a necessity. This process does more than just make the engine run; it correctly configures the module to work with your car’s unique features, anti-theft system (Passlock/VATS), and transmission controls. Ordering a generic, non-programmed programmed 12602044 ECM would result in a no-start condition and require costly dealer intervention. We handle this essential step for you, ensuring your vehicle accepts the new module and operates flawlessly from the first key turn.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians will then use this VIN to flash the ECM with the exact GM software and calibrations for your specific 2006 Cadillac XLR, including all factory options.
Is this a difficult part to install?
The physical installation is typically straightforward for someone with basic mechanical skills. The ECM is usually located in the engine bay and secured with a few bolts and electrical connectors. Since our module is pre-programmed, the most difficult part of the job is already done for you. We always recommend disconnecting the battery before starting the installation.
Will I need to have my keys reprogrammed?
In most cases for this GM platform, a simple security relearn procedure is required after installation, which you can do yourself in about 15-30 minutes without any special tools. We include instructions to guide you through this easy process.
Is this compatible with other part numbers?
Yes, this ECM is a direct replacement for multiple GM service numbers, including 12590032, 12603530, 12605843, 12607096, 12630457, and 19210737. If your original module has one of these numbers, this unit will work perfectly for your vehicle.
What information do I need to provide?
All we need is the Vehicle Identification Number (VIN) from your vehicle. You can typically find this on your driver’s side dashboard (visible through the windshield), on your vehicle’s registration, or on the driver’s side door jamb sticker.
