What Does It Mean?

How to Fix P0B30 Code

Check the “Possible causes” listed above. Visually inspect the wiring harness and associated connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P0B30 Possible Symptoms

Check engine light illuminated (or service engine soon warning light)

P0B30 Meaning

The HV battery uses nickel-metal hydride batteries and does not require external charging. The power management control ECU maintains the HV battery’s SOC (state of charge) at a constant level during driving. The HV battery consists of 28 modules, with each module containing eight 1.2V cells connected in series. The battery smart unit monitors the battery block voltage at 14 locations. Each battery block consists of 2 modules in an assembly. The battery smart unit, which monitors battery block voltages, determines that a malfunction has occurred if the voltage difference between battery blocks exceeds the standard. When the malfunction detection condition is met, the power management control ECU (HV CPU) illuminates the malfunction indicator light (MIL) and sets a diagnostic trouble code (DTC).

P0B31 – Low Voltage of Hybrid Battery “D

P0B31 Possible Causes

Faulty intelligent battery unit
