What does code P2D80 mean?

Q: What does code P2D80 mean?

Charging Start Switch Circuit Low. P2D80 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the charging start switch circuit, which is used to signal the start of the charging sequence in some hybrid and electric vehicle systems. The PCM expects to see a specific voltage on this circuit when the charging process is initiated, and a low reading means the circuit is shorted to ground or the switch is stuck closed.
