My Tesla Model S is Dead

[Fedaa Fawzi]

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?

There is a pyro on the 12v but it’s probably ok. Better off connecting the battery terminals to a working 12v to get the contactors to close so it can charge the HV battery.

something that i have to check

Remember the car is really a self-propelled computer with a big battery. I suggest you follow the reboot procedures, in order, from this link:

Reboot instructions for your Tesla

Your Tesla may require a reboot or hard reset from time to time, this is how you do it.

tesla-info.com

If none of these work you will need to have Tesla review the logs and clear them.
