Principles of Operation

PRINCIPLES OF OPERATION

The horn system consists of a relay, a steering wheel switch and either 1 or 2 horns. The horn(s) receives voltage from the switched side of the relay on circuit 29S-GJ1 (OG/BU). The relay switch is controlled on its ground side by the steering wheel switch or the generic electronic module (GEM).

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

The steering wheel switch shares the steering wheel clockspring with the air bag circuit, although each of these systems work completely independent of each other.
