What does PCS-A084 mean?
Tesla alert code in the Power Conversion System (PCS) module. PCS detects an dangerous voltage drop on DC link when the voltage is in drive inverter's parasitic diode region PCS does not receive CAN messages from VCFRONT Charger does not receive all expected CAN messages from front vehicle controller Charger recieves all expected CAN messages from front vehicle controller DCDC converter does not regulate LV bus voltage to target, 12V battery may not charge correctly DCDC tank current period is too long, indicating that DCDC FETs are not switching properly Charger DC output current exceeds maximum output current threshold
