Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need the Vehicle Identification Number (VIN) from your 2006 Cadillac DTS. This allows us to program the ECM with the correct software and calibrations for your specific vehicle configuration.
Is this part difficult to install?
The physical installation is typically straightforward for a qualified mechanic or an experienced DIYer. The ECM is usually located in the engine bay. Since the unit arrives pre-programmed, no special computer tools are needed for the installation itself. However, some vehicles may require a security or key relearn procedure, which can be done without special tools. We recommend consulting a service manual for your specific vehicle.
Will I need to do anything after installation?
In many cases, the vehicle will start and run perfectly after installation. However, some GM vehicles require a simple “relearn” procedure for the anti-theft system (Pass-Key/VATS) or crankshaft position sensor. These procedures can typically be performed without any special tools and instructions are widely available online or in service manuals.
Is this a new or used part?
This is a high-quality, tested, and inspected original equipment part that has been professionally programmed to ensure it meets or exceeds factory performance standards.
