The P0BB0 fault code refers to a low voltage condition 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 cells30 cell groups, section two has 72 cells24 cell groups, and section three has 126 cells42 cell groups.

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, and the readings are transmitted to the 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.

What are the possible causes for the automobile fault code p0bb0?

If you see the engine light or service engine soon warning light on, the fault code P0BB0 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. It’s important to address these possible causes to resolve the problem.
