For your firmware version you need to be at or near a Service Center in order to activate Service Mode.
The Geofence was removed with firmware version 2022.20.6 and newer.
Any idea on how to force the car to install 2022.20.6? It downloads it but never updates, probably because of my error codes that I need to check lol
13 MS85 VIN 9919
Just updated to 2022.8.10.8 ( 2022.8.10.8 Official Tesla Release Notes - Software Updates (notateslaapp.com) ) today and was able to get into service mode for the first time. Tried in previous firmware version (don't know what version was prior) and did nothing. All service mode attempts were done at home (not near SC)

My car does not seem to want to do its update because of its pending faults. UGH.
Diagnosing this car can be quite challenging. Factory tools are generally inaccessible. Here is a sequence of diag tools. Setting up OBD2 to snoop canbus is a good next step unless you can jump all the way to factory tools (workshop) CANBUS snoop at least will tell you which subsystems are reporting in.

I recently had to diag an HV circuit fault that prevented battery main contactors from closing. OBD2 was able to snoop BMS and show all battery modules were good. From JRGo video, sounds like HV battery maybe completely dead? Anyway, you can read first 3 posts on my diag path. My HV battery main contactor didn't close but sounded like it tried and failed the testing after precharge contactors fired. Post #5 I tried to explain what I heard.

Anyhow, hope this gives you some clues on chasing next steps

13 MS 85 can't go into drive, recent LDU rebuild, some clues from clicking sounds
73k miles. Won't go into drive with a bunch of error codes (looks like HV loop disabled). LDU rebuild completed ~ 2weeks ago and driven 350 miles before this problem. Error codes shows repeated attempts to connect HV (presumably to charge 12V and heat battery?) until 12V got too drained and...

Thanks man. The car is still saying the battery is at 61% so im really hopeful for a repair vs replacement.Diagnosing this car can be quite challenging. Factory tools are generally inaccessible.

I recall JRgo video shows pulling speed sensor shows rusty water residue. If the inverter is dead from coolant intrusion and not responding to HV battery precharge, I'd imagine battery is not going to fire its contactors. And if HVIL safety loop is broken anywhere along the way, HV battery will not fire any contactors.
Wrote up and linked some background info on HVIL, precharge, and contactors. Probably good to familiarize yourself
Thanks for the reading material! I am assuming you are correct as well, just the inner technician in me wants a definitive "yes/no" before I go firing the parts cannon. My only reason is I have the ability to buy salvaged vehicles so it would make the most sense to just grab a low milage 85 of the similar vintage to be a battery donor, and that would then give me an LDU as well. Trying to keep this thing the cheapest clean title tesla on the internet is a goal of mine!
Indeed no parts cannon which gets $$$$ on this car. Don't want to throw a $10k battery at it if not needed but drive unit rebuld/replacement seems surely the case.. Just note nothing says the used drive unit will not be leaking given its high failure occurrance. Anyhow, ScanMyTesla app + ELM327 BT dongle + custom Tesla OBD2 connector shape adapter will get you CANBUS status
I will be pacing my driveway Friday waiting for Amazon to drop off my adaptor to which I pray let’s me see the status of my batteryIndeed no parts cannon which gets $$$$ on this car.
