This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2017 Cadillac CTS 3.6L 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.

I was a bit nervous about replacing the ECM myself, but this 2017 Cadillac CTS 3.6L unit was exactly what I needed. The fact that it came VIN programmed saved me so much hassle — I just plugged it in and everything fired right up. Shipping was surprisingly quick, which was a huge relief because my car was out of commission for a few days. The fit and finish were perfect, and the car runs smoother than before. I’m really happy with how straightforward the whole process turned out to be.
