CUSTOMER CONCERN Customer states the malfunction indicator light is on. DTC P0A93 is stored, and the inverter water pump runs briefly before shutting off when commanded with a scan tool. CAUSE The pump retained battery voltage and ground but would not continue operating, confirming an internally failed inverter water pump. CORRECTION Remove and replace inverter water pump. Refill and bleed inverter cooling circuit, clear DTC P0A93 and verify commanded pump operation.

CUSTOMER CONCERN Customer states the vehicle will not start after the discharged 12-volt battery was replaced. DTC P0A0D returns immediately. CAUSE Inspection confirmed the high-voltage battery service-plug grip was not fully seated, leaving the safety interlock open. CORRECTION Correctly seat and latch the high-voltage battery service-plug grip. Clear DTC P0A0D and verify READY-mode operation.
