P0B81: Understanding The Hybrid Battery Pack Cooling Fan Control Circuit
The P0B81 fault code refers to a circuit issue in 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 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 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.
The P0B81 fault code specifically indicates a circuit issue in the HybridElectric Vehicle battery, specifically related to Battery 15.
