2005 Jeep Liberty 3.7L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2005 Jeep Liberty 3.7L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with our cloning service.
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
Important Note
Some vehicles with IMMO or PATS require key programming after installation. This is normal.
For a 100% plug-and-play solution, we recommend using our full cloning service. We transfer all security data to the replacement unit.
A prepaid shipping label will be emailed to you. Allow you to mail in your original computer to us for full cloning.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Kevin Parker –
I purchased the 56044666AB ECM for my 2005 Jeep Liberty and was really impressed with how smoothly everything went. The unit arrived quickly with free shipping, which was a nice bonus. What stood out most was the professional VIN programming service—they had it set up perfectly and ready to go right out of the box. Communication was clear throughout the process, and I felt confident in the quality of the repair.

The programming was spot on and the plug-and-play setup made installation a breeze. Shipping was quick and free, which was a nice bonus.
Great experience overall—fast turnaround and they answered all my questions right away. The ECM worked perfectly on my 2005 Jeep Liberty.
I appreciated how professional the ECU programming service was, and the shipping cost was very reasonable. Highly recommend this seller!
