Key In Ignition Reminder

The BCM activates the key-in-ignition audible warning as requested by the ignition key alarm switch. The key-in-ignition warning sounds when the following occurs:
^ The ignition switch is OFF.
^ The body control module (BCM) determines that the driver's door is open (signal is low).
^ The BCM determines that the key-in-ignition switch is closed (signal is low).
