HYBRID CONTROL SYSTEM, Diagnostic DTC:P0BCE-313, P0BCF-312

DTC Code DTC Name
P0BCE-313 Generator Inverter Temperature Sensor Circuit Low
P0BCF-312 Generator Inverter Temperature Sensor Circuit High

DESCRIPTION

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