The P0B30 fault code refers to a problem with the voltage stability of the hybrid battery.

The hybrid vehicle (HV) battery is made up of nickel metal-hydride batteries and does not require external charging.

The power management control ECU is responsible for maintaining a constant state of charge (SOC) of the HV battery while driving.

The HV battery consists of 28 modules, with each module containing eight 1.2 V cells in series.

The battery smart unit monitors the voltage of the battery block at 14 different locations.

Each battery block is made up of two modules. If the voltage difference between the battery blocks exceeds the standard, the battery smart unit detects a malfunction. When this happens, the power management control ECU (HV CPU) will illuminate the Malfunction Indicator Lamp (MIL) and set the P0B30 Diagnostic Trouble Code (DTC).

In summary, the P0B30 fault code indicates an issue with the voltage stability of the hybrid battery, which is monitored by the power management control ECU and the battery smart unit.
