This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2014 Jeep Grand Cherokee 3.0L 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 vehicles 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 on my 2014 Jeep Grand Cherokee, but this unit arrived ready to go right out of the box. The VIN programming was spot on, and installation took no more than 20 minutes. The Jeep fired up immediately with no issues or warning lights, which was such a relief after the headaches I’d had before. Shipping was surprisingly quick, too, so I didn’t have to wait long to get back on the road. Overall, this has been a smooth and hassle-free experience that saved me a trip to the dealership.

The ECM arrived quickly and was exactly as described. Installation was straightforward since it came fully programmed to my Jeep’s VIN—no extra coding needed. The engine runs smoothly now, and I’m really impressed with how hassle-free the whole process was. Definitely a great buy for anyone needing a replacement ECU.
