Description
2010 Toyota Avalon 3.5L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2010 Toyota Avalon 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.

Jack Nelson –
This ECM fit my 2010 Avalon perfectly and arrived super quick—installation was a breeze with no hiccups. Highly recommended!
Swapped out my old ECU with this one and my car runs like new again. Plug-and-play was exactly as promised, couldn’t be happier!
Fast shipping and flawless fit! The VIN programming saved me a ton of time and hassle, very impressed with the quality.
Perfect match for my Avalon’s system, and the install was as simple as advertised. Great product and top-notch support if you need it.
Love how this ECM came ready to go—no extra coding needed. My 3.5L runs smoother than ever, thanks!
