Q: What does code P1510 mean?

Back UP Power Supply. P1510 on a Chrysler vehicle indicates that the Powertrain Control Module (PCM) has detected a fault in the backup power supply circuit, which is the dedicated memory keep-alive feed that preserves adaptive learning and diagnostic data when the ignition is off. The PCM monitors this circuit and sets the code when voltage on the backup power input falls outside the expected range or is lost entirely.
