DESCRIPTION
The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, detects the temperature of the motor inverter using the motor inverter temperature sensor. The inverter cooling system operates independently of the engine cooling system. The motor generator control ECU (MG ECU) uses signals from the motor inverter temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the motor generator control ECU (MG ECU) will limit inverter output to help prevent inverter overheating. The motor generator control ECU (MG ECU) also detects malfunctions in the motor inverter temperature sensor and its wiring.
