The P1B79 code refers to a low voltage issue in the HybridElectric Vehicle battery pack. The battery pack contains 288 cells grouped in parallel and in-series. There are three battery sections, each made up of a different number of cells and cell groups.

The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules. The battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2. The P1B79 code is a fault condition that can be determined by the battery energy control module.

What are the possible causes of the P1B79 automobile fault code?
