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 with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

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.
