Code P0562 Jeep Description

The Motor Generator Unit (MGU) has the Hybrid Control Processor (HCP)built into the MGU. The HCP provides the strategy for charging the Power Pack Unit (PPU). The PCM provides the strategy for the 12 volt charging system. The HCP monitors the 48 volt system, B+, switched ignition, crankshaft pulse signals and CAN bus circuits for any concerns. The HCP can also detect any internal failures, high temperature and resolver failures.

The Battery Pack Control Module (BPCM) is contained within the 48 volt Power Pack Unit (PPU). The BPCM provides battery management and system functionality in conjunction with Cell Supervision Circuits (CSCs) that monitor and balance the battery cells as well as the monitoring of related external support systems. The CSCs are also located within the Battery Pack. The BPCM communicates with the vehicle via CAN-C bus. The main functions of the BPCM are to manage battery voltage and maintain the 12 volt battery system using battery pack current, voltage and temperature sensing capabilities. CAN communication is used to monitor other vehicle systems and for fault detection reporting. Diagnosing any DTC related to the BPCM should start with verifying that all fuses, wiring and connections critical to proper system operations are in good repair, securely installed and connected.

The Diagnostic Trouble Code (DTC) will be set when the Hybrid Control Processor detects that the battery voltage is below 8.5 volts.
