The P1B46 code indicates a low voltage in the HybridElectric Vehicle Battery 33 Circuit. The battery pack contains 288 cells grouped in parallel and 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 communicates diagnostics and system status to the hybridEV powertrain control module 2 through serial data.

The hybridEV powertrain control module 2 is the host controller for diagnostic trouble code information.
