The P1B2B code refers to a fault in the HybridElectric Vehicle battery pack. The battery pack contains 288 cells grouped in parallel, with a total of 96 cell groups connected in-series. The battery energy control module monitors the voltage of the 96 battery cell groups through the four 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 through serial data. The P1B2B code specifically refers to a fault in the battery’s 30th circuit. All components related to the battery energy control module, hybridEV battery interface control module, and battery control harness are serviceable.
