Description
2018 Jeep Grand Cherokee 3.6L ECM / ECU VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2018 Jeep Grand Cherokee 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 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.

Swapped out my old ECU with this one and it fired right up—super quick delivery and zero hassle installation.
This ECM fit perfectly and worked flawlessly from day one; really impressed with how straightforward the whole process was.
Got my Jeep running smoothly again thanks to this plug-and-play unit, plus the support team was quick to answer all my questions.
Installation was a breeze and the programmed ECU matched my VIN perfectly—definitely worth every penny.
Fast shipping and an exact fit for my 3.6L Grand Cherokee, made what could’ve been a headache super easy.
