Fasten Safety Belt

The seat belt data is received from the Body Control Module (BCM) via the class 2 serial data line. The BCM sends a signal in order to turn on the seat belt warning indicator when the following 2 conditions occur:
^ The BCM detects that the ignition switch is in the RUN position.
^ The seat belt has not been latched.
