The ECM monitors the voltage level on this circuit. If it detects a voltage when the signal is commanded OFF, it records this fault code.
1)ECM Idle Shutdown feature set up incorrectly.2)Open circuit in the idle shutdown relay, OEM harness, or connectors.3)Short circuit to a voltage source in the OEM harness or relay.
1)Replace the idle shutdown relay.2)Repair or replace the OEM harness.
