Description
2019 Jeep Grand Cherokee 6.4L ECM / ECU VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2019 Jeep Grand Cherokee 6.4L 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 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.

The ECM arrived quickly and was truly plug-and-play—my Grand Cherokee fired right up without a hitch. Super impressed with the seamless install!
Adam Parker –
I was a bit nervous about replacing my Jeep’s ECM, but this unit arrived quickly and was ready to go right out of the box. It fit perfectly, and the VIN programming meant I didn’t have to mess around with complicated setup. After installation, my Grand Cherokee ran smoother and more responsive than before. Definitely recommend for anyone looking to upgrade without hassle.
