Many people assume any ECM with a matching part number will work. This is a critical misunderstanding.

Using a non-programmed or incorrectly programmed unit can lead to no-start conditions or even damage other components. Our service eliminates this risk entirely. By programming the module with your VIN, we ensure it integrates seamlessly into your Cadillac’s electronic ecosystem, just as a new one from the factory would. This is the key to a successful and lasting repair.
