Horn Operation - Vehicles Without Adaptive Steering

The horn switch consists of 2 sets of contacts separated by springs. The lower set is connected to ground and the upper set is connected to the horn signal circuit. When the driver airbag module is pressed, it pushes down on the upper set of contacts, collapsing the springs and allowing the contacts to touch. When the contacts touch, it completes the circuit and provides the ground signal which is routed through the clockspring, SCCM and then to the BCM. The BCM then energizes the non-servicable horn relay located in the BCMC. When energized, the horn relay provides voltage to the horn, enabling the horn to sound.
