Horn: Description and Operation

HORN

There are 3 separate conditions that can cause the horn to sound. The horn sounds if the driver presses the horn pad, when the remote keyless entry is armed, or during an anti-theft event. The horn system uses a horn relay to provide voltage to the horns while the horn switches and the front electronic module (FEM) provide the control grounds to engage the horn relay. The horn switch is located behind the driver air bag module. For the removal and installation of the horn switch, refer to Horn Switch. The FEM is located behind the LH A-pillar lower trim panel. For removal and installation of the FEM, refer to Body Control Systems (Multifunction Electronic Control Module).
