P0Bb4 Fault Code: Understanding The Description And Troubleshooting Steps
The P0BB4 fault code refers to a performance issue in the circuit of the 25th battery in a hybridelectric vehicle. The hybridEV 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 specific batteries within a range. The battery energy control module monitors the voltage of the 96 cell groups through hybridEV battery interface control modules.
Voltage sense circuits are attached to each cell 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 information to the hybridEV powertrain control module 2 through serial data. The powertrain control module 2 is responsible for diagnostic trouble code information. In the case of the P0BB4 code, it indicates a performance issue in the circuit of the 25th battery in the hybridEV vehicle. This fault needs to be diagnosed and addressed to ensure proper functioning of the battery system.
