The P0B52 fault code refers to a high voltage issue in the HybridElectric Vehicle battery circuit. 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 3.7 V. The nominal system voltage is 355 V DC. The battery cells are divided into three sections. Section one has 90 cells, section two has 72 cells, and section three has 126 cells.

Each section contains a specific range of batteries. The battery energy control module monitors the voltage of the cell groups through interface control modules. These modules encode the voltage readings and transmit them to the battery energy control module. When a fault condition is detected, the battery energy control module communicates the diagnostics and system status to the powertrain control module. The P0B52 fault code indicates a high voltage problem in the HybridElectric Vehicle battery circuit.

It is important to address this issue promptly to ensure the proper functioning of the vehicle.
