Description
2012 Lexus IS350 3.5L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 Lexus IS350 3.5L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.
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
This ensures a fully functional, reliable, plug-and-play module you can install with confidence.
Important Note
Some vehicles equipped with IMMO (Immobilizer) or PATS (Passive Anti-Theft System) may require additional key programming after installation. This is normal for models where security data must be synchronized with the vehicle’s body control system.
For a 100% plug-and-play solution with no relearns, no key programming, and no compatibility issues, we recommend our ECU Cloning Service, which transfers all original security, immobilizer, and configuration data directly into the replacement unit.

I was a bit nervous about replacing my Lexus IS350’s ECU myself, but this unit made the whole process surprisingly straightforward. It arrived quickly, and everything was already programmed to my VIN, so installation was truly plug-and-play. After swapping it in, my car fired right up without any trouble or warning lights. I appreciate that the seller was available for a couple of quick questions, which made me feel more confident. Overall, it’s a great product that saved me time and unnecessary trips to the shop. Highly recommend if you want a hassle-free fix!
