eBay'd a replacement RCM Cleared the crash lock Cleared the VIN redeployed

Pin#4 on J1 and J3 (Red and White 4pin contactor connectors) on the charger side are connected to ground on all three chargers (the installed one and two spares). I'm assuming pin#4 is connected to ground on all Gen1 chargers. There is no connection to ground on the contactor connectors when...

It's possible! I have another ebay'd HVJB still in bubble wrap I can try. I also have some Gen2 HVJB+Charger pairs coming I can try. And/or I can swap HVJB+charger with another S and see where the problem goes. I've just been spinning my wheels for so long I don't know what the best...

I am looking for advice or ideas as to why I am unable to supercharge. There are no errors prior to plugging in the supercharger handle into the charge port. L2 AC charging at home works flawlessly. Pressing the button on the supercharger handle causes the charge port door to open as it...

Nope... replaced the HVJB. That didn't help either. Next I'll try re-seating the HV battery pack LV connectors.

yes... Gen1 and Gen2 have HVJB in the center... master on the passenger side... and optional slave on the driver side under the rear seat.

I went ahead and tried it... Yes, it was messy. Physically swapped them. Left slave unplugged reprogrammed master plugged in slave, unplugged master reprogrammed slave Plugged master back in redeployed it changed the cpld firmware on each charger from 26 <-> 10 and vs vs. I can still...

My 2012 S P85 has dual 10kw 6009278-00-F Gen1 chargers. The car is unable to supercharge receiving the "No Power" error when attempting to Level3 Supercharge. The car AC charges just fine at 48a (max output of my wall charger) from a Gen2 wall connector. Having read through this thread... My...

Please let me know how this goes for you.

I'm interested in knowing if anyone knows a way to get updated SSL keys without being eligible for eMMC recall or upgrading to MCU2. I would imagine having the Tegra board replaced would have SSL keys recreated in the process. Or maybe there's a procedure for tesla service to just reprovision...

Killing the IC's eMMC is not a big deal... just replace the IC. They're only like $200 on eBay. Do a software-redeploy after it's physically swapped and if the rest of the car is in working order, you should be good to go.

You could replace your Tegra board with eBay 256166977500 2020.36.16 board. You would however need to have your SSL keys extracted off the current eMMC in order to maintain communication with Tesla aka App access.

Can you ping the IC from the CID? Can you issue a redeploy? nc cid 25956 service-redeploy

It's not quite that simple... the Spansion flash chip needs to match the eMMC firmware. You can't just replace the eMMC with different firmware and expect it to work. You need to write the same firmware version the Spansion last installed and booted to onto the replacement eMMC unless you...

FYI: you don't need ssl keys for the car to run. you just won't have phone app access or anything that requires communication with Tesla. I could provision you a reasonably plug-and-play CID with nothing more than your vehicle config (gateway.cfg aka internal.dat) and even if you didn't have...

None that I'm aware of. I've been working on a 3rd-party web-based app replacement for CIDs running older firmware (2020.36 and earlier) for vehicles that for whatever reason no longer have valid keys. What firmware are you running? or is the vehicle even running at this point? Alternative...

you won't find them in the IC dump... at least not on firmware recent enough where the keys would still be valid. The certs expire after 2years if not renewed and firmware old enough to keep keys on the IC would be too old to be renewing. They don't exist on the IC at all. You can mail me the...

The key you found is for RSA testing. This is not the key to your car. Below is the key you found and the matching certificate for your information. You can google parts of it and find this RSA pair used quite a bit. -----BEGIN RSA TESTING KEY-----...

How are you reading the ram? They are on the CID not the IC. They are in /var/etc/openvpn/car.crt and /var/etc/openvpn/car.key on the CID where /var is p3 so... <p3 mountpoint>/etc/openvpn/car.crt <p3 mountpoint>/etc/openvpn/car.key openvpn isn't used anymore but that's still the path. that...

They are not encrypted... you'd need the car.crt and car.key pair. If you have these two files, I can verify them for you.

May I ask what software/device was used to gather this info and generate these reports?

In the Gateway which is a chip on the large main board in the MCU (not the Tegra)

A Tesla cannot go 2years without communicating with Tesla or the certs it uses to communicate with Tesla will expire. Unless Tesla has something in place that allows renewal even after the vehicle's certs have expired, it will never talk to Tesla again without Tesla replacing the certs (likely...

Yay! It’s not in my car’s navigation yet but it’s on Tesla.com and it works

I stopped in yesterday and it looks complete other than it’s still fenced in. There’s arrows painted in the spots showing the direction you need to face in order to charge. It’s possible you’d need to back in or out when other vehicles are charging otherwise you’d likely just drive through...

T thank you. This response was significantly more constructive than the last.

LOL @ Bathroom Silicone.... that'd be a fun surprise when investigating a pack. You seem pretty confident with your "100% chance". What separates a module swap with "100%" chance of failure from a Tesla/057/ReCell remanufactured pack if proper sealant is used? I very much appreciate hearing...

Can you reference the "some ppl" claims? It's not that I don't believe you... I'm curious myself. There's so much misinformation out there, it's hard to determine what's real vs bad assumptions, etc. Matched BMB revision (physically looked the same). Both original and donor BMB were the...

Not only was the BMB bad but there was also a sense wire that had come off. It seems oddly coincidental the C27 corrosion issue to be on the same module as the loose/detached sense wire. Have others seen corrosion and loose/detached sense wires? Does one cause the other? FYI: The entire...

Progress!

I'd suggest using the link light as your "Step 1" before worrying about the display lighting up. Could be: Bad Tegra board (more specifically the eMMC on the Tegra board) Insufficient/bad/dirty 12v power (quality power supply?) Incorrect/bad Fakra/HSD cable (has it ever worked?) Main board...

Do you get a link light? Do you get anything with tcpdump?

I'm having very similar f107 issues on a 2012 P85. I verified corrosion on C27 (BMB failure) and replaced the BMB. The delta between cell#3 and cell#4 dropped from ~80mv to ~60mv after the BMB swap however the periodic drop from ~3v to ~1v persisted on the same module even after the full BMB...

Was the root cause of the "suddenly drop to 1.6v then back up to 3.6v" every determined?

FYI: the certs are good for 2 years from the renewal date.

Do you recall what happened after this?

Who wants to take some guesses at what my issue is? Current goal is to charge the pack, it's pretty low right now. Just purchased a 2012 S P85 in non-running condition. I know charge port door is physically corroded and the bottom pin is broken. I scraped some of the corrosion off for it to...

the gateway is crypto locked and ssh to cid /tegra no longer accepts password or local id_rsa ssh key logins after 2020.36.

The process you used to get to 2022.8.5 won’t work to get that far back. You’d need reflash your emmc and spansion flash (involves soldering) https://www.ebay.com/itm/256166977500

You’d want to downgrade all the way to 2020.36 or earlier in order to gain root login access, be able to adjust any and all configuration settings in the gateway, prevent updates, etc.

What did you downgrade to? What are next steps ?

It’s in /usr/local/bin/gwxfer on the CID and can only be run from the CID so it won’t do you much good if you don’t have the ability to login to the CID.

My p85 was stuck on the side of the freeway because it said I had 6% left but told me to pull over it’s shutting down … it was there for 4 days because AAA trucks for whatever reason “wouldn’t tow a Tesla”. I just needed to get less than 2 miles to a place I could charge. That’s what...

ICharger x6

Out of the single module ? Realistically… maybe 7 miles and would likely take a few hours

I designed a mount that 3d prints as a single piece without any supports that worked perfectly for me. Custom 3D Print mounting bracket Note: the wire with the black stripe is Negative - and the solid color is Positive + (at least on my 2013 P85 but believe that's pretty standard)

SUCCESS! My mobile emergency charging setup has been verified and works. I'm able to use: Standard 24v Tesla Battery Module 5kw AliExpress 24v input inverter A plug bonding Neutral to Ground <-- This was the missing piece Standard Tesla mobile charger A power strip so I had somewhere to...

I typically just remove the Emmc and reflash it in a programmer … I’ve never tried accessing the IC Emmc through the boards pins. You’d likely run into issues with mismatched spansion flash chip info even if you did manage to directly access the Emmc.

I’m only familiar with rooting model S/X MCU1, sorry, I’m no help.
