    I have left my Tesla in the garage for vacation for about a week, so i come back to the car dead,

    I jumped the car but I reversed the polarity of the jumping cables, connecting the positive on the battery negative, I did it by mistake, i heard humming sound coming from the front of the car, after I realised what i did, i tried to jump it the right way but it’s completely dead, nothing works at all, the cluster display turns on then it says service required .

    I checked all the fuses in the 3 fuse boxes and they are all ok, replaced the BCM and head unit also nothing changed. Is there safety fuse or something that i have to check? Of so where its located and if there is no fuse, where do i start?

    None that I know of. I've heard of more than one Prius that were reverse jumped and blew out every controller. Total Prius loss.
