Description
2016 GMC Terrain 2.4L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2016 GMC Terrain 2.4L 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.

This ECU fit like a glove and was already programmed to my VIN, saving me tons of time. Highly recommend for anyone needing a quick, reliable replacement.
Plug-and-play is no joke here—swapped it in minutes and my GMC is running smooth again. Came fast and the setup was totally hassle-free.
Super pleased with this ECM; it matched my VIN exactly and installation took no time at all. Plus, customer support was really helpful when I had a quick question.
Got my Terrain back on the road in no time thanks to this ready-to-go, factory-programmed module. Shipping was speedy and the whole process was seamless!
