Original Description
Charging faulted due to high measured grid impedance (impedance detection algorithmn) PCS DCDC detects its temperature is too hot to continue operation DCDC converter temperature exceeds overtemperature threshold for more than one second DCDC converter temperature is below overtemperature clear threshold PCS charging input under-frequency Charger AC input frequency is below minimum frequency threshold for more than one second Charger AC input frequency exceeds minimum frequency threshold Charger input line over current Charger AC input current exceeds maximum input current threshold Charger intermediate bus over voltage Charger intermediate bus voltage exceeds maximum intermedate bus voltage threshold
Severity Notes
PCS-A056 is an Alert in the Power Conversion System system. It is generally safe to continue driving, but have it checked at your next scheduled service.
