DTC P3000-389: Battery Control System [11/2016 - ]: Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
The hybrid vehicle control ECU assembly alerts the driver and performs fail-safe control based on error signals received from the battery voltage sensor.
This DTC is stored if the HV battery is discharged excessively or the hybrid control system malfunctions.
HINT:
If the HV battery voltage has dropped due to a malfunction in other components such as the inverter with converter assembly or the hybrid vehicle transaxle 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.
