Error: Precharge too long

[daspace]

Hello everybody!
Maybe someone has seen and fixed problem with precharge circuit? I have already tried to swap DC-DC convertor, motor, nothing changed. Maximal voltage seen as spike on HV line is 250 volts for a second maybe, when car tries to close contactors. It tries many times after some intervals when voltage drops to 0. Any help would be appreciated, maybe some units to be checked? System gives error BMS_f150_SW_precharge_too_long

Hi neighbour.
Even though it almost doesn't matter it is not very effective talk about a problem and not mentioning is it with somebody's girlfriend or any specific type of vehicle. For example Tesla?

I found the problem. It was because of bad HVAC module, HVIL was interrupted there.
