Description
2019 Lexus ES300h 2.5L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2019 Lexus ES300h 2.5L 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.

This ECM/ECU unit fit perfectly with my 2019 Lexus ES300h, and it was a breeze to install thanks to the VIN programming already done. Everything worked flawlessly right out of the box, which saved me a ton of time and hassle. Shipping was quick, and the customer service team was very helpful when I had a few questions. Highly recommend this for anyone needing a reliable replacement.

I recently replaced the ECM on my 2019 Lexus ES300h with this unit, and I couldn’t be happier with how smooth the process went. The module arrived quickly and was already programmed for my VIN, which saved me a ton of time and hassle. Installation was straightforward—just plug it in and go—and my car started right up without any issues. It feels like I have the same reliable vehicle, if not better, now that the ECU is brand new. Definitely a stress-free buy for anyone needing a quality replacement.
