DTC P0BCC-11: Generator Inverter Temperature Sensor Circuit Short to Ground; DTC P0BCC-15: Generator Inverter Temperature Sensor Circuit Short to Battery or Open [12/2019 - 11/2023]: Description

The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, detects the temperature of the generator inverter using the generator 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 generator 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 generator inverter temperature sensor and its wiring.
