What does code P2AD4 mean?

Q: What does code P2AD4 mean?

Intermediate System Voltage Low. P2AD4 indicates that the powertrain control module (PCM) has detected an intermediate system voltage that is lower than the expected range for proper operation of a specific circuit or module. The PCM monitors voltage levels on a dedicated intermediate power circuit and sets this code when the voltage falls below the calibrated threshold for a set period of time.
