PCS_a075_hvBusDischargeTimeout
What does PCS-A075 mean?
Tesla alert code in the Power Conversion System (PCS) module. PCS DCDC timed out when attempting to discharge HV bus DCDC converter timed out when attempting to discharge HV bus Inability to perform vehicle precharge, CHAdeMO and GB DC compatibility may be impacted Input voltage measurement changed too much between switching cycles (only active in phase A) Charger AC input voltage changed too much between switching cycles Charger input line over voltage Charger AC input voltage peak level exceeds maximum input voltage peak threshold Reduced AC charge rate or inability to AC charge, possibly due to incompatible grid PCS DCDC temperature sensor is reporting irrational value DCDC converter temperature is outside expected range for more than one second DCDC converter temperature is within expected range Reduced available DCDC output power PCS DCDC HV bus voltage reading differs from HVP HV bus voltage reading by an excessive amount DCDC converter high voltage bus voltage sensor mismatches high voltage processor's sensed value on CAN for more than three seconds DCDC converter high voltage bus voltage sensor matches high voltage processor's sensed value on CAN for more than 500ms
