Condition
Functional condition is unconfirmed; no bench-test or diagnostic report is supplied. Testing history and programming/security settings have not been independently verified. Connector faces and individual terminals are not visible in the available photos and have not been verified.
Used housing has scratches, dirt, discoloration, oxidation/residue, white paint marks and label abrasion/staining. Main OEM/DENSO identifiers remain readable; inspect the housing and mounting cutouts.
Compatibility & installation
Catalog vehicle production period: September 2004–September 2005, not this ECU’s manufacture date. Not universal for all 2004–2006 Sienna, AWD or later 3.5L versions. Match full OEM/DENSO numbers, connectors, engine/transmission, calibration, production date and market/emissions specification. Donor VIN, software, hardware version and manufacture date are unconfirmed; no alternative number is promised interchangeable.
Single ECU, not a matched security set or assumed plug-and-play. Immobilizer status/stored data are unconfirmed. A Toyota specialist may need initialization/registration, immobilizer/key procedures, coding/calibration checks, fault clearing and adaptations. Fitting alone does not guarantee starting.
