    Hy,
    i have problem with DTC P3107-214 is mitchell is write's like HV ecu no communication with airbag ecu (short to +b or open in communication line).
    I changed airbag ecu it's the same dtc comes.
    Then i changed HV ecu and also dtc comes.
    Beside made a wire directly from airbag ecu to hv ecu.
    And no changes.

    Maybe, some one has the same problem?

    Thanks

    Please see the attached PDF for how to troubleshoot the problem. Most likely one of the pins in the wiring harness has become disconnected.

    Anyone can help me to troubleshoot P3107-214 on my Prius 2010? Toyota dealer is saying it might take few days , they will charge $120/hr till they find. Any help will be appreciable. I am not sure where to find the pinout to L16 and all. I have located one module under the passenger seat and one under the gear shifter. Please help me. Thanks in advance
