P0B4B Fault Code: Understanding The Description And Troubleshooting Steps
The P0B4B fault code refers to a performance issue in the fourth circuit of the HybridElectric Vehicle battery. The battery pack consists of 288 cells, grouped in parallel sets of three.
There are a total of 96 cell groups connected in series, with each group rated at 3.7V. The nominal system voltage is 355V DC. The battery cells are divided into three sections. Section one has 90 cells (30 cell groups), section two has 72 cells (24 cell groups), and section three has 126 cells (42 cell groups).
Each section contains a specific range of batteries. The battery energy control module monitors the voltage of the cell groups through hybridEV battery interface control modules.
These modules encode the voltage readings and transmit them to the battery energy control module. If a fault condition is detected, the battery energy control module communicates this information to the hybridEV powertrain control module 2, which serves as the diagnostic trouble code host controller.
