Code B2580 2016 Chevrolet Silverado Description

The high beam and flash-to-pass functions are contained within the turn signal/multifunction switch. The Body Control Module (BCM) provides the turn signal/multifunction switch with two signal circuits, the high beam signal circuit, and the flash-to-pass signal circuit. When the low beam headlamps are ON and the turn signal/multifunction switch is placed in the high beam position, ground is applied to the BCM through the high beam signal circuit. The BCM responds to the high beam request by applying ground to the high beam relay control circuit which energizes the high beam relay. With the high beam relay energized, the switch contacts close allowing battery voltage to flow through the high beam fuse to the high beam control circuits illuminating the high beam headlamps.
