The P1B37 code refers to the Battery Energy Control Module Hybrid Battery Voltage Balance Processor 4 Performa. The hybrid battery pack contains 32 cell groups connected in series, each rated at 3.7 V.

The battery energy control module monitors the voltage of each cell group through a voltage sense circuit. To maintain proper battery function and lengthen battery life, the battery energy control module balances the voltage of the cells using internal voltage gates. The startergenerator control module monitors the cell voltages and determines which cells need energy removed to maintain a similar state of charge.

The P1B37 code indicates an issue with the battery energy control module’s ability to balance the voltage of the cells.
