2010 Lexus RX350 3.5L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2010 Lexus RX350 3.5L 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 about ordering an ECU online, but this 2010 Lexus RX350 ECM arrived quickly and exactly as described. The best part was that they programmed the unit to my VIN before shipping, so installation was truly plug-and-play with no guesswork involved. Customer service was fantastic—they answered all my questions promptly and kept me updated on the progress. Shipping was free, which was a nice bonus considering how heavy these units can be. After installation, my Lexus runs smoother than it has in years. Highly recommend this seller for anyone needing a reliable, ready-to-go ECM.
