The P0B4E fault code refers to an intermittent or error in the Hybrid Battery Voltage Sense ‘D’ Circuit. This circuit is responsible for monitoring the voltage of the battery blocks in the HV (High Voltage) battery of a hybrid vehicle. The HV battery is made up of 28 modules, each consisting of eight 1.2V cells in series.

The battery smart unit, which monitors the voltage of the battery blocks, detects a malfunction if there is a voltage difference between the blocks that exceeds the standard. When this happens, the power management control ECU (HV CPU) will illuminate the Malfunction Indicator Lamp (MIL) and set the P0B4E Diagnostic Trouble Code (DTC).

It is important to address this fault code promptly as it indicates an issue with the voltage sensing circuit of the HV battery. A qualified technician should diagnose and repair the circuit to ensure the proper functioning of the hybrid vehicle.

Ignoring this fault code may lead to further complications and potential damage to the HV battery system.
