    Look below the steering column, a standard OBDII port is there. You will be able to access generic mandated OBDII codes, manufacturer-specific may not show up

    The Prius uses the CAN protocol which is not supported in some lower cost OBD2 readers (I have one that doesn't do CAN). If it doesn't sync up, you will need a new one. The AutoGenuity with the Toyota option can read most of the codes:
    AutoEnginuity® - OBD2 Scan Tool - Professional PC and PDA Diagnostics
    but is expensive.

    The ScanGuage:
    ScanGaugeII - Trip Computers + Digital Gauges + Scan Tool
    can read some of the hybrid codes using its "XGauge" feature.

    I have scangauge2 that does not read inverter or traction battery temps with the Xgauge. Will the autoenginuity tool extract these temps from a 2009 Prius C.A.N. potocol?>>>Tortus

    Autoenginuity or any "real" scantool that is Toyota-enhanced
    can read that stuff. The Scangauge cannot because it doesn't
    handle multi-frame responses. See some of the Scangauge / Xgauge
    threads over on CleanMPG for more info, and/or this
    and the "network packet" dump linked therefrom.
