Horn: Description and Operation

HORNS SYSTEM DESCRIPTION AND OPERATION

SYSTEM DESCRIPTION
The horn system consists of the following components:
- The HORN fuse
- The horn relay
- The inflatable restraint steering wheel coil
- The horn

SYSTEM OPERATION
The vehicle horn is activated whenever the horn switch is depressed.

CIRCUIT OPERATION
Battery positive voltage is applied at all times to the horn relay coil and the horn relay switch. Pressing the horn switch grounds the horn relay control circuit. When the horn relay control circuit is grounded, the horn relay is energized and battery positive voltage is applied to the horn through the horn control circuit. The horn sounds as long as ground is applied to the horn relay control circuit.
