The P0B4C fault code indicates a low voltage condition in the HybridElectric Vehicle Battery 4 Circuit. The battery pack in a hybridEV contains 288 cells grouped in parallel. These cell groups are connected in-series to create a nominal system voltage of 355 V DC.

The battery cells are divided into three sections, with each section containing a specific number of cells. Battery section one has 90 cells, section two has 72 cells, and section three has 126 cells. The battery energy control module monitors the voltage of the cell groups through the hybridEV battery interface control modules.

These modules encode the voltage readings and transmit them to the battery energy control module.

When the battery energy control module detects a low voltage condition in Battery 4 Circuit, it triggers the P0B4C fault code. This information is communicated to the hybridEV powertrain control module 2 for diagnostic purposes.

To resolve this issue, the battery and its associated components, such as the battery energy control module and the hybridEV battery interface control modules, may need to be inspected and repaired or replaced if necessary.
