P0B91: Understanding The Causes And Solutions For This Automobile Fault Code
The P0B91 fault code refers to a performance issue in the 18th 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 nominal system voltage is 355V DC. The battery cells are divided into three sections.
Section one has 90 cells30 cell groups, located adjacent to the cowl. Section two is behind section one and contains 72 cells24 cell groups. Section three, the transverse section, has the remaining 126 cells42 cell groups.
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 battery energy control module. If a fault condition is detected, the battery energy control module communicates this to the hybridEV powertrain control module 2 for diagnostic trouble code information.
