High Beam Feedback

Range: High Beams ON/High Beams OFF
The BCM uses this input in order to determine the state of the high beam headlamps. A single wire input into the BCM monitors the high beam headlamp voltage. When the high beams are illuminated, the display will show high beams ON. When the high beams are not illuminated, the display will show HIGH BEAMS OFF.
