P0ADC
The drive motor generator battery control module compares the contactor control circuit to the drive motor generator battery control modules
internal 12 V measurement reference circuit. This DTC sets when the contactor control circuit voltage and the drive motor generator battery control
modules internal voltage reference are within 2 V of each other when the high voltage positive contactor is commanded open.
Action Taken When the DTC Sets
DTCs P0ADB and P0ADC are type C DTCs.
