BMS_F150 fault, car unable to drive

[terofin]

Model S 2014, was charger at my home, then unable to drive, then i put it factory mode, and see that "precharge too long"

What should i check next?

some guy from latvia has same problem, and he has faulty HVAC controller.

how i can check do i have same issue?

i have t-diag, but i'm not very professional with it...

If someone can help me, it would be great!

Yes, I have the same codes. I have checked all the fuses and changed the 20A and 40A fuses in the HV junction box (although they checked out fine). I will replace the 12v battery when a new Ohmmu one arrives in a few days. If that doesn’t help, I will have it towed to the SC. I will keep you posted on any progress and hope that it might help you.

In my case, it was due to the PTC heater being shorted and that prevented the contactors in the big battery from closing. The PTC heater costs about $850 for the part and about $500 for labor. So far, I have experienced shorted AC compressor, battery coolant heater, and now PTC heater all led to shutting down of the HV battery. Are there any other HV components that could do this?

DC-DC converter, Charger(s), HVJB (depending on revision of charger in your vehicle), and drive-unit inverter(s).

Got the same problem with BMS_f151 and BMS_w151 error. I believe it is isolation leak related. Disconnected cabin heater from the front junction box, and BMS_f151 gone, but still got DI_u014, GTW_w018, BMS_f036
