    everyone. I was called today, to go check out a honda Civic, 2005 today, with an issue.

    What was the issue/symptoms?
    1. The auxiliary battery indicator light, is always lit, each time the engine starts.

    2. The energy monitor, does not even display the energy flow, but the auxiliary battery indicator is ON.

    3. The engine cranks, and starts, for some minutes, afterwards, the 12V depletes.
    Before this happens, there'd be sone kind of shuddering for some seconds, and car dies.

    4. The accelerator pedel does not respond when depressed (no corresponding response in RPM).

    My thoughts? I think, the traction battery is depleted, and needs to be recharged, or something?
    Scanned the ECU for codes, but got a "TP high circuit code"(can't remember the code right now though.
    Replaced the throttle body, and checked the harness on the throttle body, the power feed to it was open circuited. That, was repaired, and still had same code.

    Any suggestions over here, would be helpful to me pls.

    Suggest checking the Honda blog/ troubleshooting forum rather than those who simply know most about the Prius.

    Do we have that here, or it's in another website entirely?
