Description
2009 Toyota Avalon 3.5L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2009 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.

The ECM arrived quickly and was exactly what my 2009 Avalon needed. Installation was straightforward, and the plug-and-play design made the swap hassle-free. After installation, the car started right up with no issues, and everything runs smoothly. Customer support was helpful in confirming compatibility before I ordered, which gave me confidence in my purchase.

I was a bit nervous about replacing the ECM on my 2009 Avalon, but this unit made the process super smooth. It came already programmed to my VIN, so I just plugged it in, and everything fired up without a hitch. The shipping was surprisingly quick, which helped since I needed the car back on the road ASAP. I also appreciated the clear instructions and how it fit perfectly with no extra tweaks needed. This was definitely a hassle-free upgrade that brought my Avalon back to life. Highly recommend for anyone dealing with ECM issues!
