Is Your Vehicle Running Rough? Restore Its Brainpower.
The Engine Control Module (ECM), often called the engine computer, is the central command center for your vehicle’s engine. It controls everything from fuel mixture and ignition timing to idle speed and emissions.

This direct-fit Engine Control Module, service number 12590032, is the definitive solution for a wide range of GM vehicles, including the 2006 Cadillac CTS, restoring factory performance and reliability.

Frequently Asked Questions
Do I need to get this module programmed?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software for your specific vehicle.
Is this a plug-and-play installation?
Mostly, yes. Because it’s programmed to your VIN, it will communicate with your engine correctly. However, you may need to perform a security relearn procedure (also known as a CASE relearn or anti-theft relearn) to sync the module with your vehicle’s keys. This procedure is often simple and can be found in your owner’s manual or online.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my car’s check engine light?
If the check engine light and other symptoms are being caused by a faulty ECM, then yes, this part will resolve the issue. It is always recommended to have a proper diagnosis performed by a qualified mechanic to confirm the ECM is the point of failure before ordering.
