- Inverter Temp- (MG2)
DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs indicate the temperature sensor value for generator inverter is abnormal. The cause of this malfunction may be one of the following:
DESCRIPTION
The MG ECU, which is built into in the inverter with converter assembly, detects the temperature of the generator inverter using the temperature sensor built into the generator inverter. If necessary, the MG ECU will limit inverter output to help prevent the generator inverter from overheating. The hybrid vehicle control ECU also detects malfunctions in the sensor based on the temperature sensor values. The inverter with converter assembly detects malfunctions in the generator inverter temperature sensor and its wiring.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
---|---|---|---|---|---|
P0BCD-315 | Generator Inverter Temperature Sensor Circuit Range / Performance | Generator inverter temperature calculated by the hybrid vehicle control ECU is different from the actual temperature for 10 seconds or more, and the generator inverter temperature is excessively high. (1 trip detection logic) |
| Comes on | Master Warning Light: Comes on |
P0BD0-314 | Generator Inverter Temperature Sensor Circuit Intermittent / Erratic | Sudden change in generator inverter temperature sensor output or hunting: Generator inverter temperature is high and either of the following conditions is met:
(1 trip detection logic) |
| Comes on | Master Warning Light: Comes on |
HINT:
*: If only DTC P0BD0-314 is output, a temperature sensor malfunction is more likely to be the cause than a sudden change in actual temperature.

HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
PROCEDURE
1. | CHECK DTC OUTPUT (HYBRID CONTROL) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
(d) Check for DTCs.
Powertrain > Hybrid Control > Trouble Codes Result | Proceed to |
---|---|
P0BCD-315 or P0BD0-314 only is output, or DTCs except the ones in the table below are also output. | A |
Any of the following DTCs are also output. | B |
Relevant DTC | |

P0A93-346 | Inverter Cooling System Performance |
P0C73-776 | Motor Electronics Coolant Pump "A" Control Performance |
P314A-828 | Inverter Coolant Pump Speed Signal |
HINT:
P0BCD-315 or P0BD0-314 may be output as a result of the malfunction indicated by the DTCs above.
(e) Turn the power switch off.
B | GO TO DTC CHART (HYBRID CONTROL SYSTEM) |
