Yesterday morning, I got out of the house, opened the trunk and placed some items in and then went to leave, only the front door wouldn't open. Could not access through the app. Tried the key card. After a few attempts, it popped open, but the window didn't lower itself. Got in and the charge cable was still attached so I got back out to release it and it wouldn't respond. Tried to disconnect from the car and the screen went black. Realized the battery might be dead. Could not open the frunk. No 9 volt or 12 volt source available. Went and got a 9 volt battery and no response. Couldn't do anything so Ubered to my mom's to borrow her Model Y since my parents are out of town for the holidays then went to my business for the day. Noticed the Tesla app came online at some point and while I had it up, I tried popping the Frunk. When I got out, picked up an A23 battery just in case. Got home and Frunk had not opened. Used the battery trick and popped it open. I had my NOCO charger in there so I plugged it in. The lowest red bar started blinking slowly. So battery is dead for sure. Noticed a crap ton of codes on the screen now.
Had to manually release the charger so I could plug my mom's car in since I had kept it at 50% while they were gone. Left the 12v battery charging overnight and when I got up, the lowest bar is still red. So dead battery for sure. Pulled the ground but left the charger in supply mode. No change. I think the dc-dc converter is active and keeping power on. HV battery is losing range slowly and computer is responsive. One of the codes indicated it's unable to support switching off features to conserve energy. Though the frunk still does not open with the controls and left side doors do not open. 2 button reset doesn't work. I'm about to go pick up a NOCO jump starter.
I set up a service appointment yesterday for tomorrow morning. The estimate includes the battery replacement as well as a low voltage circuit integrity check at $275.
I'm trying to see if I can get it to respond normally with the 12v supply voltage with the hope that I will only need the battery replaced. I can't even plug the wall charger in as there is no response. A lot of functions are disabled. Anyone know how to reset everything? Here's some of the codes:
This is great start to a new year. On a side note, my security camera monitor at my business went out yesterday so gotta but a new one today as well. It's an old monitor so it's not surprising, but totally bad timing.
