The P0BB1 fault code refers to a high voltage issue in the HybridElectric Vehicle battery circuit 24. 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.

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 this information to the hybridEV powertrain control module 2, which acts as the diagnostic trouble code host controller.

In summary, the P0BB1 fault code indicates a high voltage issue in the HybridElectric Vehicle battery circuit 24, which is monitored by the battery energy control module and reported to the powertrain control module for diagnostics.

What are the possible causes for the automobile fault code P0BB1?
