Description And Operation: Horn
There are 2 separate conditions that can cause the horn to sound. The horn sounds when the driver presses the horn switch and when the panic button is pressed on the integrated keyhead transmitter (IKT). The horn system uses the SJB to provide voltage to the horn, 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 SUPPLEMENTAL RESTRAINT SYSTEM article.
