From Our Lead Technician: “On a vehicle like the Cadillac STS, the ECM is the central command. It doesn’t just manage the engine; it communicates constantly with the transmission, anti-lock brakes, and body control modules. Simply swapping in a used, unprogrammed unit will cause a no-start condition every time. Our VIN programming service ensures this 2008 Cadillac STS engine control module integrates perfectly, just like it came from the factory, but with the benefit of the newest software fixes GM has released over the years.”
Frequently Asked Questions
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship it.
Is any additional programming needed after installation?
No dealership programming is required. However, you may need to perform a simple security relearn procedure, also known as a CASE relearn or anti-theft relearn. This can typically be done without special tools and instructions can be readily found for your specific vehicle.
How do I know if this part number is correct for my car?
This module replaces a wide range of GM service numbers. The best way to confirm is to match the part number from your original ECM to one of the numbers listed (e.g., 12630457, 12607096). If you’re unsure, please contact us with your VIN, and we can verify fitment for you.
What makes this different from a used computer from a junkyard?
A used computer from another vehicle is locked to that car’s VIN and security system. It will not start or run your vehicle. Our service provides a fully tested module that is professionally programmed to your specific VIN with the latest software, making it a true plug-and-play solution.
Will this fix my specific problem?
While this 2008 Cadillac STS engine control module is the correct solution for the symptoms listed, proper vehicle diagnosis is always recommended. Please ensure the root cause of the failure (such as a shorted sensor or bad wiring) has been addressed to prevent damage to the new module.
