PCS-A009

Tesla alert code in the Power Conversion System (PCS) module. Charger is not able to regulate its input current Charger PFC current regulator error exceeds threshold Charger PFC current regulator error is below clear threshold PCS DCDC has reached its max hardware power capability Charging is inhibited due to low 12V Charger detects 12V bus voltage is below 7V for more than 500ms Charger detects 12V bus voltage is above 7V PCS has detected at least one damaged AC charging phase, AC charging power will be limited Power conversion system detected reset while enabling a phase, and did not attempt to re-enable phase Power conversion system is reset or power cycled Charger detects wall power is removed while charging info from manualPCS_A017 Charger detects wall power was unexpectedly removed while charging Charging faulted due to too large of a voltage drop between starting charge and during charge info from manualPCS_A054 Charger detects greater than 14% input voltage drop after ramping power Inability to AC charge, possibly due to bad wiring external to vehicle PCS is not able to boot CPU2 and AC charging functionality is lost Power conversion system was unable to boot CPU2 Power conversion system boots CPU2 successfully DCDC PWM enable hardline de-asserted while DCDC was commanded to be active DCDC converter detected that enable line was de-asserted unexpectedly

PCS-A009 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.
