Code P0AA6 Chrysler Description

The Battery Pack Control Module (BPCM) is contained within the High Voltage Battery Pack. The BPCM provides battery management and system functionality in conjunction with Cell Supervision Circuits (CSCs) that monitor and balance the battery cells. The CSCs are also located within the High Voltage Battery Pack. The BPCM is the High Voltage Interlock (HVIL) power source and communicates with the vehicle via CAN-C bus. The main functions of the BPCM are high-voltage bus and pre-charge contactor control, battery pack current, voltage and temperature sensing, CAN communication, fault detection, and reporting. The Diagnostic Trouble Code (DTC) will be set when the BPCM detects an insolation fault on the vehicle side of the high-voltage system. EVS lamp is illuminated, and the READY indicator may be illuminated. Vehicle operation may be affected.
