An Expert’s Note on Programming
Many people are tempted to source a used module from a salvage yard, but this often leads to more problems. A vehicle’s ECM is like its DNA; it’s coded specifically for that car’s engine, transmission, and options. Simply swapping a used one will almost always result in a no-start condition or a cascade of error codes. Our process involves flashing this 2006 Cadillac DTS engine control module not just with your VIN, but with the newest stable software release from GM. This can correct underlying factory bugs and improve overall efficiency beyond what your original module could offer.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will provide us with your vehicle’s 17-digit VIN. Our technicians will then use this information to load the precise, updated GM software for your specific 2006 Cadillac DTS onto the module before it ships. It arrives at your door ready for installation.
Will I need to do anything after installing this ECM?
In many cases, the module is ready to go after installation. However, some GM vehicles may require a simple security relearn procedure (often called Passlock or Passkey) which can typically be done without special tools. Instructions are widely available online or in service manuals. A CASE (Crankshaft Angle Sensor Error) relearn may also be needed, which requires a capable scan tool.
Is this part compatible with other service numbers?
Yes. This ECM is a direct replacement for multiple service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. It also fits a very wide range of other GM makes and models as detailed in the fitment list.
Why is providing my VIN so important?
The VIN is critical because it allows us to program the 2006 Cadillac DTS engine control module with the exact software configuration for your car’s specific options, engine type, and emissions equipment. This step is what makes our module a true plug-and-play solution and prevents compatibility issues.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence and security in your purchase.
