DTC P3000-388 HV Battery Malfunction: Description
WARNING: This page is about a different car, the 2006 Lexus RX 400h. However, it is still accessible from the selected car via links, so may be relevant.
The HV control ECU alerts the driver and performs fail-safe control based on error signals received from the battery smart unit. This DTC is output when the SOC (state of charge) of the HV battery starts to drop as a result of leaving the shift lever in the N position, running out of fuel, or a malfunction in the HV control system.
