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.

Received my programmed ECM for my 2005 Jeep Liberty quickly with free shipping—installation was seamless and the truck runs perfectly.
The team answered all my questions promptly and provided a fully programmed ECU that was plug-and-play; couldn’t be happier with the fast turnaround.
Great quality PCM delivered with very reasonable shipping costs, and the setup was ready to go right out of the box.
Fast shipping and professional programming made replacing my ECM stress-free, and the vehicle fires up without any issues.
Excellent communication throughout the process; they kept me informed and the updated ECM for my Jeep works flawlessly.

What really stood out was the plug-and-play setup — it was ready to go right out of the box, making the installation hassle-free. The engine runs smoothly now, and I’m happy with the quality of the product.

I was a bit nervous ordering an ECM online for my 2005 Jeep Liberty, but this unit arrived quickly and was already VIN programmed, so installation was a breeze. The plug-and-play setup saved me a lot of hassle, and everything fired up perfectly on the first try. Shipping was surprisingly fast and very affordable, which made the whole process even better. Their customer service also stayed in touch and answered a couple of questions I had before ordering, which gave me confidence in the purchase. Overall, I’m very happy with the quality and the smooth experience from start to finish.
