    Actually many people have said many things on this chat thread. This entire site gives me a migraine. I appreciate the helpful comments but I am not doing this for kicks,this entire ordeal has been a huge pain in the nice person. That said,

    WHEN THE CAR ENGINE IS NOT ON: 12.6 VOLTS according to the self diagnostic

    WHEN THE CAR ENGINE IS ON: 13.9 VOLTS - according to the self diagnostic

    Some say its too low voltage, ok. I will take the thing out today and charge it at autozone. Hopefully it solves the abs issue which is the entire reason I am going thru this. I've already been approved for another vehicle, this is my last ditch shot, hail mary to fix the abs. Mechanics dont want to mess with it, toyota dealer doesnt want to mess with it, etc. This is otherwise a good car.

    Wow!

    Nearly a month wasted and codes have not been read.(n)

    There is a known fault with the dash board lights going out. This is a separate issue than the ABS problems. You can chose to live with the dash going dark or have it replaced.

    Stop messing around with paper clips and 12 volt batteries and get the codes read.

    12.6 is a fine resting voltage. turn the headlights on and watch it for 5 minutes

    Like the others have said, the engine being on or off can not make any difference here. You must mean when you have the ignition on ( car says READY ) or not.

    Statements such as this one are where the confusion arises. IG-ON and READY are two different things.


    To get to this state ... Do this ... then this ... Notes
    1 ACC Foot off the brake press start button once.
    2 IG-ON Foot off the brake press start button twice. (Once again if in ACC)
    3 OFF Foot off the brake press start button a third time. (Once again if in IG-ON or READY).
    4
    5 READY Foot on the brake press start button once.

    NB: Pressing the Start button once, with your foot ON the brake, from any of the above states (ACC, IG-ON, OFF), will start the car and make it READY to drive.

    Oh yea... I guess there is that weird state between accessory and ready. What the heck is the deal with that? Is the HV on? If so then what is not READY about it? They just lock out the shifter?

    That same deal as with regular cars when you turn the key to ignition on but have not started the engine.
    Some of it. The inverter, for example.

    ok, you keep saying the dash lights go out, WHY HAS NO ONE told you that the combination meters need to be replaced when this happens. No guages means the board is bad. SImple fix. Takes about 2 hours if you have never done it before. Good luck finding a used one that isnt also broken. Toyota wont sell a new one unless they keep the car for a week while they order one from Japan with the same miles programed on it. You have two seperate problems. ABS lights on could be a lot of things. Fix the combination meter first.

    "self diagnostic"? If that's the car's "self diagnostic", the the car is very much on.

    All is dark, cold, and lifeless in inverterland, in every mode except READY.

    What ON gives you is all of the car's 12-volt equipment (dash instruments, heat blower, wipers, ECUs, etc.), but all being supplied by The Little Battery That Could Only Not For Very Long Under Those Circumstances.

    The inverter cooling pump does run then too, even though there's nothing for it to really cool, just because ON powers all the 12 volt equipment and it's in that category.
