    Hello all as the title says i had the P0A80 code so i replaced my battery. Well after that it wouldnt go in to drive or reverse. So I thought it was the 12v battery since the car did set for a month plus. So i charged the battery over night and put it back in still will not go in to drive or reverse. still says check hybrid system on the dash. i have checked the there is no dtc and only thing i see is in the permanent section and that is the P0A80 code. i have checked the on board diagnostic thing and it shows no current stuff also.

    When i power on the car i can here my battery (probably fan) but the car beeps and bitches at me and will not go in to drive so im at a lose. also the dome light will not shutoff.

    did you replace it with a new oem?

    did you complete the third step with the orange safety plug?

    Safety plug not completely locked down is the usual (and easy) culrpit.

    Check the relays as well. My first batt swap was a no-go. The bodyshop I work for and the Don-Glo brake shop printed up and troubleshot with the electrical diagrams for 2 days till they hit upon one of the relays was bad, preventing start-up of my gen2.

    Hey everybody thanks for the replies. While i was waiting for this to get approved. I disconnected everything battery wise and let it set for a few and then reconnected everything and it was fine oddly. I know when i made this post i was quite anxious. Thank you all again if i had seen these they would have helped for sure.
