What does code P2A36 mean?

Q: What does code P2A36 mean?

AFCM Power Relay Sense Circuit Low. P2A36 indicates that the All-Wheel Drive Control Module (AFCM) has detected a low voltage condition on its power relay sense circuit, meaning the module is not receiving the expected feedback voltage from the relay that supplies its operating power. The AFCM monitors this circuit to confirm that the relay is energized and delivering the correct voltage; a low reading tells the module that the relay may be stuck open, the circuit has excessive resistance, or the ground path is compromised.
