An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners try to install a used, unprogrammed ECM from a salvage yard. It almost never works.

We are not just selling you a part; we are providing a vital service that eliminates the need for an expensive trip to the dealership for programming. This is the correct way to restore your vehicle’s core functionality.

Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is the central computer, or “brain,” of your vehicle’s engine. It controls critical functions like fuel injection, ignition timing, emissions systems, and transmission shifting to ensure optimal performance, fuel economy, and safety.
Is this ECM truly plug-and-play?
Yes. Because we program the module using your vehicle’s VIN before shipping, it is ready for installation upon arrival. It will correctly communicate with your vehicle’s other modules and security systems without requiring any additional dealer-level programming.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive it. You can typically find your VIN on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will this fix my specific problem?
This ECM is the solution for problems directly caused by a faulty module, such as internal processor errors (e.g., DTC P0606). While it resolves the most common electronic engine issues, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the source of your problem before ordering.
Where is the ECM located on my 2007 Escalade EXT?
On the 2007 Cadillac Escalade EXT, the Engine Control Module is typically located in the engine compartment on the driver’s side, underneath the battery tray. Always disconnect the battery before attempting to access or replace any electronic components.
What if I have issues after installation?
Our goal is your complete satisfaction. If you encounter any issues, please contact us immediately. Our team of experts can help diagnose the situation. Remember, this part is also backed by a one-year replacement warranty for your peace of mind.
