DTC P0A93-346 Inverter Cooling System Performance; DTC P0A93-347 Inverter Cooling System Performance: Description

The inverter converts the high-voltage direct current of the HV battery into the alternating current for the Motor, Generator, and Rear Motor. The inverter generates heat during the conversion process, and this heat could damage the inverter if a cooling system is unavailable. Therefore, similar to the Motor and Generator, the inverter is cooled by a special system consisting of an electric water pump, cooling fan, and radiator. This cooling system is independent of the engine cooling system. The HV control ECU monitors the electric water pump, cooling fan, and cooling system, and detects a malfunction.
