2013 Cadillac XTS 3.6L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2013 Cadillac XTS 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 ordering an ECM online, but this 2013 Cadillac XTS 3.6L unit arrived quickly and was exactly as described. The fact that it came VIN programmed saved me so much hassle — I literally just plugged it in and my car fired right up with no issues. The install was straightforward, even for someone like me who’s not super handy with car electronics. Plus, the support team was really helpful when I had a quick question during installation. Overall, a smooth experience that brought my XTS back to life without any headaches. Highly recommend if you want a reliable, ready-to-go replacement.
