P0B31 Fault Code: Understanding The Description And Troubleshooting Steps
The P0B31 fault code indicates a problem with the hybrid battery’s voltage level.
The HV battery in the vehicle is made up of 28 modules, each containing eight 1.2V cells in series. The battery smart unit monitors the voltage of the battery blocks at 14 locations. If there is a voltage difference between the battery blocks that exceeds the standard, the 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 P0B31 fault code. This code specifically refers to a low voltage condition in battery block ‘D’.
It is important to address this issue promptly to ensure proper functioning of the hybrid battery system.
