P1Bf4: Your Car’s Battery Is In Trouble
The P1BF4 code is related to the HybridElectric Vehicle battery pack. The battery pack contains 288 cells grouped in parallel and in-series. There are three battery sections, each with a different number of cells and cell groups.
The battery energy control module monitors the voltage of the 96 battery cell groups through the four hybridEV battery interface control modules. The P1BF4 code indicates a low voltage condition in the 91st circuit of the battery. The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2.
