2004 Lexus RX330 3.3L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2004 Lexus RX330 3.3L 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.

Michael Hamilton –
I was a bit nervous ordering an ECU for my 2004 Lexus RX330, but this company made the whole process so smooth. The unit arrived quickly with free shipping, which was a nice surprise. What really stood out was their plug-and-play programming service—they had it perfectly set up for my VIN before shipping. After installing it, my car started right up with no issues, and it runs like new again. They also responded promptly to my questions, which gave me extra peace of mind throughout the purchase. Highly recommend their service if you need a reliable ECM.

I purchased the 89661-48472 ECM for my 2004 Lexus RX330 and was really impressed with the entire process. The unit arrived quickly with free shipping, which was a nice bonus. The ECU came VIN programmed and ready to install, making the swap hassle-free. Customer support was very responsive and helped answer a couple of questions I had before ordering.
