Description
2016 Cadillac CTS 2.0L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2016 Cadillac CTS 2.0L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.
Built to OEM standards for reliability, calibration accuracy, and long-term performance.
Strict Testing & Quality Assurance
Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
-
Complete communication & CAN-bus verification
-
Sensor input/output and signal integrity checks
-
Injector & ignition pulse simulation
-
Power, ground, and load-circuit analysis
-
Flash memory integrity and checksum validation
-
Thermal and voltage-stress testing to confirm reliability
This ensures a fully functional, reliable, plug-and-play module you can install with confidence.
Important Note
Some vehicles equipped with IMMO (Immobilizer) or PATS (Passive Anti-Theft System) may require additional key programming after installation. This is normal for models where security data must be synchronized with the vehicle’s body control system.
For a 100% plug-and-play solution with no relearns, no key programming, and no compatibility issues, we recommend our ECU Cloning Service, which transfers all original security, immobilizer, and configuration data directly into the replacement unit.

Logan Gray –
I was a bit nervous ordering an ECM online, but this unit arrived exactly as described and was already VIN programmed, which saved me so much time. Installation was seamless—just plugged it in and my CTS fired right up without any issues. Shipping was surprisingly quick too, and the tech support team was very helpful when I had a couple of questions. Highly recommend this for anyone needing a reliable replacement.

Perfect fit for my 2016 CTS, arrived quickly and installed without a hitch—definitely made the repair hassle-free.
Got my car running smoothly again thanks to this ECM; super easy install and the seller was great with support.
Fast shipping and zero programming needed—just plug it in, and you’re good to go.
This ECU worked flawlessly right out of the box, saving me time and money on complicated setups.
Really impressed with how simple the swap was; the VIN was pre-programmed exactly as promised.
