What does code P0ADC mean?

Q: What does code P0ADC mean?

Hybrid/EV Battery Positive Contactor Control Circuit High. P0ADC indicates that the hybrid or electric vehicle battery pack's positive contactor control circuit is reporting a voltage higher than expected by the battery energy control module. The computer detects this when the control wire voltage stays above the normal threshold, suggesting an open circuit, short to voltage, or a faulty contactor coil.
