P3000 / INF389
P3000-389Description
The hybrid vehicle control ECU alerts the driver and performs fail-safe control based on error signals received from the battery smart unit.
This DTC is set if the HV battery is discharged excessively or the HV control system malfunctions.
NOTE: If the HV battery voltage has dropped due to a malfunction in other components such as the inverter with converter assembly and the hybrid vehicle transmission assembly, recharging the HV battery will restore the voltage. If the HV battery voltage has dropped excessively after the vehicle was left for a long time, the HV battery will need to be replaced.
