Q: What does code P2AFA mean?

Starter Relay D Stuck On. P2AFA indicates that the powertrain control module (PCM) has detected the starter relay D circuit is stuck in the energized state, meaning the relay contacts remain closed even when the PCM is not commanding the starter to engage. The PCM monitors the control circuit voltage and flags this code when the signal does not match the expected off state, which can lead to a continuously running starter or a no-crank condition.
