2004 Toyota Prius 1.5L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2004 Toyota Prius 1.5L 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.

I was a bit nervous ordering an ECM online, but this 2004 Toyota Prius unit arrived quickly with free shipping, which was a nice bonus. The best part was the fact that it came already VIN programmed, so installing it was literally plug-and-play. The whole process felt very smooth, and I didn’t have to worry about additional programming steps or delays. Their team also answered a couple of my questions promptly before I purchased, which gave me confidence. After swapping it in, my Prius runs just like new again. Highly recommend this service if you need a reliable ECM replacement.
