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.
| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P0BCE | 313 | Open or short to GND in the generator inverter temperature sensor signal circuit | Inverter with converter assembly |
| P0BCF | 312 | Short to +B in the generator inverter temperature sensor signal circuit |
