Key In Ignition Reminder

The BCM activates the key in ignition audible warning at a medium rate chime frequency (150 pulses per minute) and continuous duration when the following conditions are met:
^ The ignition switch is in the OFF or ACC position.
^ The BCM determines that the key-in-ignition switch is open (signal circuit is high).
^ The Body Control Module (BCM) determines that the driver's door is open (signal circuit is low).
