    2010 prius iv non plug in. Im getting a check hybrid system warning that wont go away. The code im getting is
    DTC P3107-214 airbag ecu communication circuit malfunction
    Ive read over the pdf for diagnosing it but Im having problems locating the hv control module. Ive had the whole wiring harness out of the car so there is a good chance I broke something. Heres a picture of my prius as it sits now

    Whoa! Does @billtheengineer know about that project?

    If you're in the wiring diagram viewer, you can click Location and Routing and get a pretty good idea where the various goodies are. A lot of the ECUs (not all of them) are slotted into the big plastic ECU motel behind the glove boxes. I think the one you're looking for is one of those, but I haven't had my nose in the drawings lately.
