What does PCS-A042 mean?
Tesla alert code in the Power Conversion System (PCS) module. PCS DCDC hardware enable line does not match CAN signal DCDC converter detects that sensed enable hardline state does not match state reported on CAN for more than five seconds DCDC converter detects that sensed enable hardline state matches state reported on CAN for more than one second AC charging is stopped because DCDC is too hot DCDC converter temperature exceeds threshold for more than five seconds while AC charging is active DCDC converter temperature is below clear threshold for more than twenty seconds Charger output voltage sensor mismatches high voltage processor's sensed value on CAN Charger output voltage sensor mismatches high voltage processor's sensed value on CAN for more than three seconds Charger output voltage sensor value matches high voltage processor's sensed value on CAN for more than 500ms PCS charging input RMS over-voltage Charger RMS AC input voltage exceeds overvoltage threshold
