Q: What does code P0D5B mean?

Battery Charger 14 Volt Output Power Performance. P0D5B indicates that the battery charger system's 14-volt output is not performing as expected, meaning the onboard charging module cannot maintain the correct voltage level for the auxiliary battery. The computer monitors the charger's output and sets this code when the actual voltage deviates from the commanded 14-volt target beyond a calibrated threshold.
