Horn Relay

The scan tool displays the commanded state of the horn relay. The scan tool displays ON when the BCM allows the horn relay to go to ground to activate the horn(s). The BCM will command this state when the PANIC button on the keyless entry transmitter is activated and when there is an unauthorized entry into the vehicle.
