This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2013 GMC Terrain 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 recently replaced the ECM on my 2013 GMC Terrain with this VIN-programmed unit, and I couldn’t be happier with how smoothly everything went. The module arrived quickly, well-packaged, and was exactly as described. Installation took no time at all since it truly was a plug-and-play setup—no complicated programming needed on my end. After swapping it in, my engine fired up right away and has been running flawlessly. It’s such a relief to have my Terrain back to normal without any hiccups or warning lights.
