|Code B1897 Description

The horn relay control and switched voltage is supplied by the Bussed Electrical Center (BEC). The Smart Junction Box (SJB) receives the horn signal from the horn switch (part of the steering wheel). When the horn switch is pressed, the ground is supplied from the clockspring to the vehicle harness. The SJB then activates the horn relay. Voltage is then sent to the horn, enabling the horns to sound. The ground is provided to the horns.
