Description
2012 Jeep Grand Cherokee 6.4L ECM / ECU VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 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.

I recently replaced the ECU on my 2012 Jeep Grand Cherokee 6.4L with this VIN-programmed unit, and I couldn’t be happier with how smoothly everything went. The moment I installed it, the Jeep fired right up without a hitch, which was a huge relief after struggling with a faulty module for weeks. Shipping was quick, and the seller even provided helpful guidance when I had a couple of questions during the swap. It really took away so much stress knowing the part was ready to go straight out of the box. This was exactly what I needed to get my rig back on the road without delay.

Since switching to this ECM, the Jeep runs noticeably better and feels more responsive. Definitely a great buy for anyone needing a reliable replacement without the hassle.
