What does code P0D6D mean?

Q: What does code P0D6D mean?

A/C Compressor Motor Voltage A Low. P0D6D indicates that the powertrain control module (PCM) has detected a low voltage condition on the A/C compressor motor voltage A circuit, which typically supplies power or a feedback signal for the electric A/C compressor. The PCM compares the expected voltage on this circuit to the actual value and sets the code when the signal falls below the calibrated threshold, often indicating an open circuit, high resistance, or a faulty compressor motor.
