Description
2012 Lexus RX350 3.5L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 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.

Joel Reynolds –
Super fast shipping and the ECU arrived already programmed—installed it hassle-free and my RX350 runs perfectly.
Great communication throughout the process and the plug-and-play setup made replacing the ECM a breeze.
They answered all my questions quickly and the VIN programmed unit fit perfectly with no issues at all.
Really impressed with the quick turnaround and free shipping on this ECM; the quality is top notch.
The professional programming service saved me a ton of time—just swapped it in and my Lexus fired right up!
