    Hey Folks,

    I had the repair done by a guy from ebay. Got the board back today put everything back in BUT the car isn't working. Pretty much ALL the dash lights are on. When I scanned for the error codes I got back the following:

    Trouble Code:
    C0300

    Permanent DTC:
    C3F0A
    P117F
    P0A11
    C3F0A

    Pending DTC:
    C0700

    I must be searching in the wrong parst of the internet because I can't find good explanations for the C-Error codes.
    Please help. In the meantime I'll take the prius apart again and double check all connections.

    Thank for your help in advance,
    Chriz

    Well... Problem solved!

    I was just about to take apart the car again I realized that the orange battery disconnect on the traction battery wasn't locked all the way. I locked it fired up the car and lo and behold it starts and has no error codes whatsoever.

    Simple as that! :D

    I would not have guessed that! No reason to pull that orange safety disconnect. When the car is off, the traction battery is disconnected from the car by a relay. And there are no high voltage cables or connections around the area. But I would definitely disconnect the 12V battery to help prevent the air bags from exploding in my face.

    Anyway, glad you got it fixed with no big adventures. :)

    Am I wrong in assuming that Toyota fixed the problem with the combo meters by 2008? Reason I ask, I am working on a 2009 and While driving around and stopping, etc. then restarting, the combo meter went black... The car will run but the display is black. Do I need to replace the capacitor in the combo meter now?

    I don't remember ever reading anywhere that they fixed it. And I think I've read of it happening in the later Gen 2s, but it would be less common since they aren't as old. It sounds like you've got a classic case.

    I have an extra capacitor ( 220 micro farrad that i replaced the original 100 microfarrad capacitor with) and all is working fine. It is a known issue and the fix is pretty easy... about an hour.

    Why did you pull the hybrid battery safety interlock?

    Are you mixing up the current conversation with papawill with the one back in April with chrizoroer?

    Not mixing up anything responding to the OP's post.

    Which is becoming increasing difficult based on how many people hijack threads on this site.
