CUSTOMER CONCERN After collision repairs, DTCs P0A93 and P0C73 are stored and the inverter cooling system is empty. CAUSE The inverter coolant level was left low after collision repair, allowing air into the inverter cooling circuit and preventing normal coolant-pump performance. CORRECTION Refill and bleed the inverter cooling system with a compatible scan tool, clear DTCs P0A93 and P0C73, and verify inverter-coolant-pump speed and coolant circulation.
