Abstract
A system for controlling a vehicle horn includes a current delivery circuit and a control circuit that controls the current delivery circuit in response to a horn activation signal received from a horn pad switch. The control circuit includes a control module that generates a horn termination signal if a duration of the horn activation signal exceeds a predetermined duration. The horn termination signal is configured to cause the current delivery circuit to prevent delivery of current to the horn to deactivate the horn. The control circuit further includes a bypass circuit configured to cause the current delivery circuit to deliver current to the horn to activate the horn responsive to the horn activation signal in the absence of the horn termination signal.
