The P1BF5 code refers to a fault in the HybridElectric Vehicle battery circuit.

The battery pack contains 288 cells grouped in parallel and 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 hybridEV battery interface control modules. The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2.

The P1BF5 code specifically indicates a high voltage issue in Battery 91.

What are the possible causes of the P1BF5 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1BF5 fault code.
