DTC P0A93-346: Inverter Cooling System Performance: Description
WARNING: This page is about a different variant/trim than selected.
The inverter converts the boosted high-voltage direct-current from the HV battery into alternating current for MG2 and MG1. The inverter generates heat during the conversion process, and this heat could damage the inverter if a cooling system is unavailable. Therefore, similar to MG2 and MG1, the inverter is cooled by a special cooling system consisting of an electric water pump, cooling fan, and radiator. This cooling system is independent of the engine cooling system. The hybrid vehicle control ECU monitors the electric water pump, cooling fan, and cooling system, and detects malfunctions.
