12v Battery Disconnect

[lockbake]

My 4S was jacked up while being detailed, and when put back down the electric parking break is giving a yellow error saying temporarily unavailable. If I press P the parking break engages, but the red P flashes. I cannot get the parking break to engage when driving I.e. the green hold you get when pressing down hard on the break pedal does work.

I am pretty sure it just needs a reset and didn’t like being jacked up without being told it was (I see options in the pcm for this but it’s to late now!)

So I want to power it down by disconnecting the 12v battery to see if that helps. Is there an easy way to do this. Looks like the battery is in the front but not sure how to get access to it.. or is there a fuse I can remove?

if it does work I will have to take it to the OPC, any advice would be appreciated.

Done soft reset, factory reset first before thinking about disconnecting the 12v battery?

Soft reset by holding volume for 30 seconds.

Thanks, I’ve tried both, unfortunately still have the error.

i think the 12v ground is accessible via the frunk...and you can you can actually see the terminal.
The 12v pos is completely inaccessible, however. You have to take the whole trunk apart
