Headlamp Relay Feedback

The scan tool displays the state of the headlamps. The scan tool displays ON when the headlamp and panel dimmer switch is manually turned to the ON position. The scan tool also displays ON when the switch is in the AUTO position and the ambient light sensor is in its DARK state.
