Hey All,
2013 Model S, headed to the airport during a storm and hit several points where I floated the car. I made it to the airport just fine but 4 days later returned to the car with a dead 12 V battery. Tried to jump start it with no luck and found the dreaded isolation fault codes. I have a machines and electronics background so am going to take a stab at repair before buying a new pack. After seeing a few threads here have a newfound hope I'll be able to dry this thing out and may just repair a few cells in the process.
A couple up front questions I couldn't find after an hour or two of searching.
What sockets do I need for the HV battery removal?
Do I disconnect the coolant lines and electrical connections prior to lowering the battery?
Anyway, here are the codes. I am guessing water ingress with damaged to some BMBs.. Just ordered the OBDlink and patch cable, so hoping to get battery voltages and more info soon.
BMS_U018 SOC Imbalance Limiting
BMS_W158 Low Isolation Wrn
GTW_w405 12V Not Supported
GTW_w018 hvac load shed
BMS_u008 Limp Mode
BMS_w172 SW Drive ISO Warning
BMS_w142 SW Isolation Degradation
BMS_w123 Internal Isolation
BMS_w110 SW Vsense
BMS_w059 Pack Voltage Sensing
BMS_w050 SW BMB MIA
BMS_w026 SW Ctrs Disabled
BMS_F110 SW Module Vsense
BMS_f050 SW BMB MIA
