Description
2020 Lexus LS500h 3.5L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2020 Lexus LS500h 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 recently replaced the ECU on my 2020 Lexus LS500h with this exact programmed unit, and I couldn’t be happier with how smoothly everything went. From the moment I got it, the install was straightforward—just unplugged the old module and snapped this one in, without any glitches. The car started right up and runs perfectly now, no weird error codes or performance hiccups. Shipping was surprisingly quick, and when I had a couple of questions, their support team was knowledgeable and super helpful. This was exactly what I needed to get my Lexus back to peak condition without any hassle.
