Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module for you using your vehicle’s VIN before we ship it. It arrives ready to be installed, saving you time and the high cost of dealership programming.
What information do you need from me?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old ECM, removing a few mounting bolts, and then installing the new module in the reverse order. In some cases, a simple security relearn procedure (which requires no special tools) may be necessary after installation.
Will this fix my check engine light?
If the check engine light and associated codes are being caused by a faulty ECM, this part will resolve the issue. We always recommend having a proper diagnosis performed to confirm the ECM is the point of failure before ordering a 2006 Cadillac DTS ECM 12602044.
What is the difference between an ECM, ECU, and PCM?
These terms are often used interchangeably. ECM stands for Engine Control Module, ECU for Engine Control Unit, and PCM for Powertrain Control Module. They all refer to the main computer that manages the engine’s functions. This part serves as the primary engine computer for your vehicle.
Is this compatible with other vehicles?
Yes, this module (service number 12602044) is interchangeable with several other part numbers and fits a wide range of General Motors vehicles from that era. However, our programming service will make it specific to the 2006 Cadillac DTS you order it for.
