Principles of Operation

PRINCIPLES OF OPERATION

The horn system consists of a relay, the steering wheel switch 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 steering wheel switch or the generic electronic module (GEM).

The horn relay is supplied with constant voltage from the battery junction box (BJB) on circuit 30-DA1 (RD).

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