I am using tbx2 to check iso as this is simplest way for me. It can however be read by any can tool or simply by listening udp messages. With regards to reseting errors, please refer to previous post from WK057 TESLA MODEL S stopped working... CAR MAY NOT RESTART

I check and it looks like fluid contaminated sensor. Need to clean it, repair and stop leakage, somehow...

Here comes some pictures from my past measurement. It shows either: 1) sudden drop to about 255kohm (from around 1400kohm) for few seconds. This is when I was driving with AC on, while BatteryyHeater unplugged 2) sudden drop to 0 kohm (from around 1400kohm). This was after I stopped car, when...

Iso, I am reading can signals through tbx - when running test. Manually by disamble each part and checking using isolation resistance tool testing 250 or 500v depending on the part. After few errors (10?), I am getting permanent error and power/regen is limited. I know, this is not solution, but...

Hi, hopefully someone could give some advice what I can do more, what to check more and what could be reason of my isolation problem. I experience isolation for about year. Recently it happens more often. I checked each and every HV component, each wire and all looks good. Isolation for ptc...

I saw two cars from 2013 with gen1 charger (checked by myself) with ccs (plc) box attached (same molex plug as on gen2 chargers - 12pin). Both cars come from US and were charging on ccs2 in Europe. I do not know how they did it, as I retrofited by myself only 2015+ vehicles. Once were about to...

Ecu inside white box is exactly same and replaceable. Only wiring is different: Molex 20 or 12 pin and you install it in different way (one or two screw)

I own P85D, salvage car. US vehicle. HV test switch off SuC but also otherfastcharge was disabled in my case. I could not (temp) charge DC at all. I have (in my vehicle from 2015.06) onboard Type2 charger. Used plc ecu and ccs works perfect. No other changes were needed, just retrofit as...

Not sure which handle version you have but follow my picture and orange circle. There should be microswitch which touches screw. This screw should be adjusted so the switch enable itself earlier or later. This screw as I recall can be adjusted also from installed handle. As adjustment can be...

Btw, charger gen1 can be retrofited same as gen2 or gen3

If you are only changing mentioned flags, there is no cryptografic restrictions. Most likely you locked gtw and need to unlock it. I had same. Unlocking is as easy as changing wheels ;-)

Hi there. Silly question - is it possible to retrofit gen1 (2012-2014 I believe)? I did it with gen 2 (2015) and gen3 (2017), but now someone asked me with car from 2013...it has pretty old onboard charger. I know that wiring for charger gen2 and gen3 are slightly different (different plugs)...

This is what I also heard. Still however not clear how it works. I belive this is one of the odin process, which backup all my personal data to cloud like garage or to bms or to usb. Running it (I believe require tbx with special priviliges) is alternative to what @KyleDay wrote in his manual...

To add, I have Model S from 2015, dual motor with large rear unit (Performance). And looking for expected iso.res. on wiring going from HVJB to: - rear inverter drive - battery (plugged via rapid mate) I found someone showing resistance on the inverter like 6 MOhm, so mine 4.8-5 MOhm is...

Hi. Unfortunately I experience error w_172 isolation resistance problem (+ limo). BMS shows 1680 MOhm (sometimes drop to 1640 MOhm), but I measured all components and could not find any of them dropping below minimum described in Tesla biuletin (which I think is not up to date). I thought it is...

I hoped to see biuletin how Tesla is doing entire swap to better understand their process. I would be interested on the processes they have to run (e.g. using toolbox) to backup data, to reteieve data on new MCU2 and so on. I also works on retrofit. Have all parts (I believe) from wreck car and...

Optional upgrade also has its own biuletin/manual - like slave charger.

Long time this topic was not replied, but I hope there are still fellows reading it and keen to help :) I am searching for buletin/manual of Tesla, describing their process of retrofit MCU2. Similar to tons of other official Tesla buletins already published over internet. If anyone would have...

Great post! It encourage me to do the same on my AP1 Tesla :-) Just about to buy all parts (MCU2 + IC2). Considering also to buy radio, but not sure which one should be applicable. For EU there are at least 3: 1052609-00-A or 1052609-01-A or 1143709-00-C. I suppose, I should use the last one...

Thank you mates :-) Really appreciated - as finally someone (YOU) explained and confirmed what is possible and what not. Few times I heard that once I will upgrade, my vehicle will reconnect (by miracle, automatically). Now I know, I can have new soft, but only Tesla will reconnect me allowing...

Someone could confirm? This is what I was afraid of and even manual upgrading to newest firmware will not help. The only Tesla service might do this reconnection....

Yes, I wakup vehicle this year. In Jan'20 I connected to internet (repaired car itself and replaced sim etc) while it was last time visible on Tesla servers back in 2017 (verified with Tesla). Meantime it lost all updates, including migration to 18.26 and 20.4.

Hi. Unfortunaly I have 2017.32.6 :-( Not connecting to Tesla servers at all (host unknown message display on watch on cid-upd).

Hi All. I am trying to upgrade firmware of my car as I am still running 18.1 and I would like to refresh the soft a little bit. As my car has salvage title, Tesla Service is not very helpful. Therefore, I planned to play it by myself. As I understood, I have to go through sequential update...

Yeah, it looks like my software is too old to run. I have to update. However, problem with internet connection (not browser problem although this is most visible symptom, but lack of internet connection for certain sites and lack of connection with Tesla servers) was found much earlier - before...

Without working internet connection I am unable to upgrade :-( Visiting Tesla SC is an option, which yet I would like to avoid, as I have salvage car.

So I did some further check and found that it is not only problem with browser, but also - now confirmed - problem with entire system, which is not connecting with teslamotors.com while checking firmware update (cid-updater, watch): cid-updater: 6813: get_connected_tcp_client...

Not sure if mine will count in this statistics, as I have 85kW, but after switching off all online function (which for me does not work anyway - salvage car), daily loss now is about 2km/24h. Before switching off online function, it was something like 5km/24h (or more). Checked now, and after...

Not sure you manage to repair it, but I had same for my driver door. It is just a simple adjustment of the handle (one sensor has to be adjusted by slightly pulling one screw). First of course you have to remove handle from the door - and there are few good movies showing how to do this. It...

I have salvage Tesla S model (2015). Repaired and working fine (I really enjoy this car) ... however have problem with internet connection. It was since beginning - some web pages or internet radio stations does not work. Not sure why and what is wrong, but some are opening (like google.com)...
