Horn: Description and Operation

INTRODUCTION

Horn System - Schematic:

The horn circuit consists of a horn switch, horn relay, and horns. The horn circuit feed is from fuse 3 in the Power Distribution Center (PDC). When the horn switch contact is depressed, it completes the ground circuit to the horn relay. Then the horn relay coil, closes a set of contacts in the relay allowing current to flow to the horns. The horn is grounded to the headlamp ground.

The Electronic Entry Module (EEM) is in parallel with the horn switch and can also activate the horn system for vehicle theft/security.

Horn Location:

The horns are located under the front bumper and fascia. Mounted on the right and left outer side of the frame rails.
