P1D82: Your Car’s Battery Needs Attention

The P1D82 fault code is related to the Voltage Control Unit (VCU) in an automobile. The Motor Control Module receives an abnormality signal from the VCU detected by the Motor Power Inverter (MPI) module. If the FOVCU signal is high and the FOALL signal without the OR of the abnormality signal from the MPI module is low for a set time, the motor control module detects a malfunction and stores a DTC.

This code specifically indicates a malfunction in the signal line H of the VCU.
