    I'm newbie and sorry to put here because, I couldn't send from another place where there wasn't show sending button. Any way,
    I bought a05 Prius month ago that has 275.210 miles with SKS(only 1 key and not work ) navigation etc and running good until yesterday.

    But now have a starting problem after reconnected ground cable on 12V battery. When push button to accessory, Display shows few second and next on position, both cooling fan runs high speed (even 2 connector on A/C module disconnect)
    and dash panel indicator shows only no number of speed (attached picture) and It's NO START with brake pedal depressed, of cause and this is my problem.

    When pushed the button for engine off, only shift indicator on dash panel brinks (hard to shoot picture) and disappear when removed fob key out.
    Other problem on A/T transmission is parking mode and unable to move car to out side of garage.

    I probably fried my ECM(s) and more control module such a A/C and others may be. Right now navigator, P/door lock, only driver side P/ window, lighting system are working all right.
    Q1 If I got used one from like e-bay and still do car need reprogramming at the dealer ? Or
    Q2 Is there any way to shifter move to neutral?

    Q3 Do Instrument need to replace or repairable ?

    I appreciate for any your thought and thank you in advance.

    After reconnecting the ground cable, you need to press the start button 2 times (or is it 3) with your foot on the brake to get to READY. Try that before doing anything else. If you have warning lights on after making the car READY, you have diagnostic trouble codes (DTCs) set and you need to have them read to determine what is the problem. Otherwise all anyone, including yourself, can do is guess.

    what were you doing that you disconnected the battery cable?

    have you tested the 12v health?

    Well, I probably forgot to reply to my post and here now is car is running good after they fixed ( replaced relay=170 ohm).

    I was told that they said if HV Control Module did not receive power via P C Mtr Relay when power on it's not recognize the shifting position pattern and after received bad relay. it's 1.7K ohm and became 170 ohm after solder on broken wiring.
    I hope this one help others. and
    Thank you for your respond. Pubrica(y)
