Principles of Operation

PRINCIPLES OF OPERATION

The horn system consists of a relay (part of the central junction box [CJB]), the horn switch (part of the drive air bag module) and 2 horns. The horns receive voltage from the switched side of the relay. The horn relay is controlled on its ground side by the horn switch or the generic electronic module (GEM).

The horn relay is supplied with constant voltage from the battery junction box (BJB).

The horn switch shares the clockspring with the air bag circuits, although each of these systems work completely independent of each other.
