Horn System Description and Operation
System Description
The horn system consists of the following components:
System Operation
The vehicle horn is activated whenever the horn switch is depressed.
The BCM commands the horns ON under any of the following conditions:
Circuit Operation
The BCM controls the horn operation, when the horn switch is pressed, it closes a switch pulling the horn signal circuit low. When the BCM detects the drop in voltage in the horn switch signal circuit, it energizes the PCB Horn relay which provides B+ voltage to the horn control circuit, sounding the horn.
When the vehicle is in the Off Power Mode the BCM will attempt to detect a stuck or continuously activated horn switch. When enabled, activation of the horn will be limited to 10 seconds to protect the horn from excessive use.
