P0C71 Fault Code: Understanding The Description And Troubleshooting Steps
The P0C71 fault code refers to a correlation issue between hybrid battery temperature sensors ‘D’ and ‘E’.
These sensors are located in three different areas of the HV (high-voltage) battery in the vehicle. Each sensor contains a thermistor that measures the resistance, which changes with the HV battery temperature. When the battery temperature is low, the thermistor resistance is high, and vice versa. The battery smart unit utilizes these temperature sensors to detect the HV battery temperature and sends the information to the power management control ECU.
Based on this data, the power management control ECU regulates the blower fan. The blower fan is activated when the HV battery temperature exceeds a predetermined level. The P0C71 fault code indicates that there is a discrepancy or inconsistency between the readings of temperature sensors ‘D’ and ‘E’. This can lead to improper control of the blower fan, potentially affecting the cooling system of the HV battery.
It is important to address this issue promptly to ensure the proper functioning and longevity of the hybrid battery system.
