Is Your Cadillac Not Performing As It Should?
If your 2006 Cadillac CTS is experiencing frustrating issues like a persistent check engine light, erratic engine behavior, poor fuel economy, or even a no-start condition, the root cause is often a failing Engine Control Module (ECM). As the central computer for your vehicle’s engine, a faulty ECM can create a cascade of problems that compromise the performance and reliability you expect. This isn’t just a replacement part; it’s the definitive, plug-and-play solution to get your Cadillac running perfectly again.

Frequently Asked Questions
Do I need to do any additional programming after I receive it?
No. We handle all the programming for you. This ECM will arrive flashed with your vehicle’s VIN and the latest GM software, making it ready for a plug-and-play installation. In some cases, a security or crank relearn procedure may be necessary, which can be performed by most qualified technicians.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the order notes or reply to your order confirmation email. We will not ship your part until we have the VIN to ensure perfect programming.
My original part number is slightly different. Will this still work?
Yes, this ECM is a compatible replacement for a wide range of GM service numbers, including 12590032, 12602044, 12603530, and others listed in the description. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
Will this fix my check engine light?
If a faulty ECM is the cause of your check engine light (often indicated by codes like P0601-P0606), then this part is the correct solution. However, we always recommend a proper diagnosis by a qualified mechanic to ensure the ECM is the true source of the problem before ordering.
What is the installation process like?
The physical installation is straightforward. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in its place. While many customers can perform this task, we recommend professional installation if you are not comfortable working on your vehicle.
