The P0BB5 fault code refers to a low voltage condition in the HybridElectric Vehicle battery circuit 25. 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) located adjacent to the cowl, batteries 67 to 96. Section two, behind section one, has 72 cells (24 cell groups) from batteries 43 to 66.

Section three, the transverse section, has 126 cells (42 cell groups) from batteries 1 to 42.

Each section is individually serviceable. 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, terminating at a connector on the top surface of the battery section. The voltage readings are encoded and transmitted to the battery energy control module. When a fault condition is detected, the battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2, which is responsible for trouble code information.

What are the possible causes for the automobile fault code P0BB5?

If you see the engine light or service engine soon warning light on, the fault code P0BB5 could be the culprit. This code is often caused by a faulty hybrid/electric vehicle battery pack or a faulty hybrid/electric vehicle battery interface control module. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes listed above for a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the P0BB5 fault code?
