Horn: Description and Operation

HORN

There are 2 separate conditions that can cause the horn to sound. The horn sounds if the driver presses the horn switch and when the vehicle security system is armed. The horn system uses the smart junction box (SJB) to provide voltage to the horns, while the horn switch or the SJB can provide the ground to engage the horn relay. The horn switch is integrated into the air bag. For the removal and installation of the air bag, refer to Air Bag Systems.
