Horn: Description and Operation

HORN SYSTEM
The horn circuit consist of a horn switch, horn relay and horn.

The horn circuit feed is from the fuse to the horn relay in the Power Distribution Center (PDC). The PDC is mounted on the battery tray. When the horn switch is depressed, it completes the ground circuit. The horn relay coil closes contacts and allows current to flow to the horn. The horn is grounded to the headlamp ground connection.

HORN SWITCH
The horn switch is mounted between the outer and inner cover of the Driver Airbag Module.

When the Driver Airbag is pressed, the horn switch makes contact to ground. The ground signal is carried to the horn relay and the horn sounds.
