Horn: Description and Operation

HORN

There are 4 separate conditions that can cause the horn to sound. The horn sounds if the driver presses the horn switches, when the remote keyless entry is armed, when a theft event occurs, or when the panic alarm is activated. The horn system uses a horn relay to provide voltage to the horns. The smart junction box (SJB) provides the ground control to engage the horn relay. The horn switches are integrated into the driver air bag module and the steering wheel.

For removal and installation of the driver air bag module, refer to Air Bag Systems.

For removal and installation of the steering wheel, refer to Steering.

For removal and installation of the SJB, refer to Body Control Systems (Multifunction Electronic Control Module).
