General Information

HEV Control System
P0562 System Voltage Low - General Information

Component Location





General Description

The HCU is connected with the MCU, the BMS and the PCM through High speed CAN. and connected the PCM, the ESC, the OPM, the FATC, the CLU etc through Chassis CAN. The HCU will control EV (Electircal Vehicle Mode) and HEV mode with these CAN communication. The HCU monitors the battery voltage to determine, as a safety issue, whether this system can operate normally or not. The normal battery voltage range is essential for controlling this system as intended.

DTC Description

The HCU monitors the voltage of battery and if it stays below a certain value, this DTC is set.
