Fasten Safety Belt Warning

The BCM sounds the fasten seat belt reminder ON warning for 5.4-6.6 seconds when the following conditions exist:
^ The ignition switch is turned from the OFF position to the RUN position
^ The driver's seat belt is unfastened (ground signal in circuit 238)

If the driver's seat belt is fastened and unfastened within the 6 second chime period, the BCM stops the chime while the driver's seat is fastened. The BCM resumes the chime for the 6 second period if the driver's seat belt is unfastened.
