The P0B72 fault code refers to a circuit issue in the HybridElectric Vehicle battery system.

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 battery cells are divided into three sections: section one with 90 cells, section two with 72 cells, and section three with 126 cells. Each section is individually serviceable. 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 control module. When a fault condition is detected, the battery energy control module communicates it to the powertrain control module, which is responsible for diagnostic trouble code information. In summary, the P0B72 fault code indicates a circuit problem in the HybridElectric Vehicle battery system, specifically related to the 12th circuit.
