I have a September 2016 UK model S, I'm wanting to retrofit mainly a heated steering wheel, ideally rear heated seats, I also have a 2018 salvage S which had the cold weather pack, so I have wiring, seats, steering wheel, slip ring/ stalk unit. I've searched here & surprisingly can't find any...

Does anyone know what a normal cell difference would be while driving underload? I read above up to 400mv is the typical or the maximum??

Thanks I’ll have a proper look at the document JCM_76 I’ve been trying to work out where the high resistance comes from, but think I’ve been over thinking it! With a reading of 3000 kohm with contactors open the resistance must be gained by the main BMS module within the battery pack. It’s only...

I’m in the UK, we can currently get toolbox3 for 1 hour - £33 1 day - £120, 1 month £400, 1 year - £3,000. Prices vary don’t know if it’s the exchange rate or Tesla adjusting it. The Toolbox software isn’t the best. If I were you I would defiantly remove the HV cover on the rear motor & see...

Not sure say to photograph but attached picture of corroded earth to HV rapid disconnect. I’ve not removed it but it looks like this is how the main centre pin earths to the chassis. I accessed service mode plus through toolbox, paid 1 day licence fee & left it in plus mode, not sure if I will...

Hi Juan I currently have the exact same issue as you on my 2014 model S. Sorry to jump on your post but hoping we can assist each other. Your battery cell reading look very healthy so dont think you have any issues there. I have my battery pack stripped. Reading the isolation resistance from...

Thanks. Does the fact the whole module voltage is a consistent 22.76v not mean the module is ok then? Thanks for the info, I assumed if the module are all equal the batteries were ok but your right if one or two cells are out it wouldn’t show across the entire pack. I’ll check the individual...

Update I have a cell difference 2.5v but the reading are very erratic & does this on modules 8 & 10. It will show all cells approx 3.6v then 2 cells from module 8 & 2 from 10 will suddenly drop to 1.6v then back up to 3.6v the faulty cells are in the same position on scan my Tesla; 1st row...

I have a 2014 Model S with a refurbished 2020 85 battery pack. Car won’t drive or charge, shows numerous errors Using scan my Tesla I have a big imbalance issue, ranges in seconds from 1000 to 2245mV The bit I don’t understand is the voltage in modules 8 & 10 fluctuate between 3.6v to 1.6...

Are there any indi shops on here that use toolbox 3 or are people using aftermarket like Loki. They are all expensive, don’t mind paying as long as it works. I’ve read loads of info stating toolbox 3 is very limited & not dealer level, not much info about Loki other than the people selling it...
