DTC P3000-388: 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 when the SOC (state of charge) of the HV battery starts to drop as a result of leaving the shift lever in N, running out of fuel, or a malfunction in the hybrid control system.
