I'm currently repairing a post water ingress battery pack and I'm also considering all the improvement that I can make before to reseal it. You mean, to design a cap with a gore valve to integrate one (or two) in place of transparent cap near the umbrella valve ? I have everything at my...

Pyrofuse on a 240kW 70D is really recommended ? It makes sense on a performance model or with ludicrous option but I can't imagine it can blow on this model ? I don't really like the idea to mount a second hand pyrofuse that won't be easily accesible on this battery model...

Yes you can download it when you have access to the online toolbox. (I got it now if you need it) I paid 1h access to reset the isolation error on the bms. So I confirm, (on a 2015 70D Model S with MCU2) in case of BMS_F123 and/or BMS_W123 there is a real serious internal problem that must be...

Yes that's the official Tesla tool (available online on tesla service) that allow to connect directly on the battery pack on the X036 connector, the grey one (Molex MX150 connector reference : 33472-1202) Wiring of the X306 connector is as follow : CAN-H : pin10 ; CAN-L : pin9 ; +12V : pin2 ...

I managed to get the isolation value of the standalone battery pack before to open the main lid. Unfortunately I don'y have any point of comparison as I never get this value before to open the fuse lid and the front cover of the battery pack. But at this point the isolation provided by the bms...

So, I finally bought this car. BMS_f123 -/ BMS_w123 errors is (one more time) clearly a water ingress issue in the battery pack. I started to open the battery pack, I will remove and check all the modules before to decide if I repair+reseal this pack of if I sell the modules to buy a complete...

Hi, did you found any useful information about this harness + software tool ? Thanks

H Hi, did you found this tool ? Or at least CAN ID where we can find Isolation value ?

It means that the only way to get pack isolation value on a non-rooted mcu legacy TMS is to pay a toolbox session ?

The tesla_models_awd file seems to be coherent with a 2015 version id but isolation it not defined in this file. Isolation seems to be defined in tesla_models.dbc file but this definition seems to be for a more recent car version ? I'm surprised this information is not well known and identified...

Hi, I can't find clearly this information, does the battery pack isolation value is published on CAN3 powertrain (on a TMS70D 2015). If yes on which ID is it ? Thanks

Ok, that's why I was not able to find isolation value and detailed informations on the MCU . I didn't have root option in mind... Is there someone able to give me the CAN id where I can find the isolation value ? Thanks !

I had the opportunity to check more deeply today on the car. Indeed cell balancing is not critical, around 15/16mV. I have a trace file of the powertrain CANBUS, I'm not sure about CAN database informations I found, isolation value is on id 0x212 ? so around 112kOhms (hex value "70" in the...

Just for clarification, these x7 can frames must be sent in a row, or a specific timing must be respected ? Thanks

Yes I read your story yesterday, it could be similar indeed. I know defaut will come back if there is water inside. So you confirm that CAN frame sequence used to reset this defaut for testing is the "Clear stress" can frame (04 31 01 04 06 00 00 00) right ? Thanks
