SECTION 413-06: Horn 2007 Edge/MKX Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 10/30/2006 Horn The horn system consists of the following components:

• Horn switches (part of the steering wheel)

Principles of Operation
The smart junction box (SJB) supplies the control and switched voltage to the horn relay (part of the SJB). When the horn switches (part of the steering wheel) are pressed, ground is supplied through the clockspring to the horn relay. The horn relay is then energized directing voltage to the horn and enabling the horn to sound. When the vehicle security system is armed, the SJB provides a momentary ground to the horn relay control side to indicate the system is armed, and an on and off ground when an intrusion is detected or the panic alarm is activated.
If your horns are not working ,you have a wiring problem or the clock spring is open . If the relay is bad the whole SJB has to be replace an the dealer would have to do that . Needs to be programmed ,with factory tool .
