Q: What does code P2D8C mean?

Fan 2 Control Module Supply Voltage Circuit. P2D8C indicates that the powertrain control module (PCM) has detected an abnormal voltage condition on the power supply circuit feeding the second cooling fan control module. The PCM monitors this circuit to ensure the fan module receives the voltage it needs to operate, and it sets this code when the supply voltage falls outside the expected range, which can prevent the fan from running and lead to overheating.
