The P0B7A fault code refers to a high voltage condition in the 13th 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 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 contains a specific range of batteries.

The battery energy control module monitors the voltage of the cell groups through interface control modules. Voltage sense circuits are attached to each group, and the readings are transmitted to the control module.

If 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 P0B7A fault code indicates a high voltage issue in the 13th circuit of the HybridElectric Vehicle battery, which is monitored by the battery energy control module and reported to the powertrain control module.
