P0B85 Fault Code: Understanding The Description And Troubleshooting Steps
The P0B85 fault code refers to the Hybrid Battery Voltage Sense ‘O’ Circuit IntermittentErra. This code is related to the HV battery in hybrid vehicles, which uses nickel metal-hydride batteries and does not require external charging.
The power management control ECU is responsible for maintaining the state of charge (SOC) of the HV battery at a constant level during driving.
The HV battery is made up of 28 modules, with each module consisting of eight 1.2 V cells in series.
The battery smart unit monitors the voltage of the battery block at 14 locations. Each battery block is composed of 2 modules in a set.
If the voltage difference between the battery blocks exceeds the standard, the battery smart unit detects a malfunction.
When the malfunction detection condition is met, the power management control ECU (HV CPU) will illuminate the Malfunction Indicator Lamp (MIL) and set the P0B85 Diagnostic Trouble Code (DTC). This code indicates an intermittent or error in the Hybrid Battery Voltage Sense ‘O’ Circuit. It is important to address this issue promptly to ensure the proper functioning of the HV battery in the hybrid vehicle.
