DTC P0BCE
DTC P0BCE: Generator Motor Inverter Temperature Sensor Circuit Low
General Description
The power control unit (PCU) monitors the IGBT chip temperature sensor value to prevent malfunction of the chip due to heat generation. If the IGBT chip temperature sensor output voltage is a specified voltage for a specified time, the motor control module in the PCU detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type
| Execution | Continuous |
| Sequence | None |
| Duration | 90 milliseconds or more |
| DTC Type | One drive cycle, MIL on, POWER SYSTEM indicator on |
Enable Conditions
| Condition | Minimum | Maximum |
|---|---|---|
| 12 volt battery voltage | 8 V | - |
Malfunction Threshold
The IGBT chip temperature sensor output voltage is less than 0.2 V for at least 90 milliseconds.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- PCU internal failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the motor control module memory.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
