Headlamps On Reminder

The radio activates the headlamps on warning as requested by the Body Control Module (BCM). The BCM sends a class 2 message to the radio indicating the chime frequency (fast rate) and duration (continuous). The headlamps on warning sounds when the following occurs:
^ The ignition is OFF.
^ The BCM determines that the driver's door is open (signal is low).
^ The BCM determines that the headlamp switch is in the park or head position.
