Calibration ID: The scan tool displays a 4 digit number. This calibration ID is
the check sum of the SDM read only memory contents.
Carline: The scan tool displays what platform the vehicle is.
Component Serial Number: The scan tool displays the SDM manufacturing source\shipping code.
Driver Frontal Loop: The scan tool displays whether the driver frontal air bag deployment
loop is enabled or disabled.
Driver Side Belt Status: The scan tool displays Buckled or Unbuckled. The signal from the
drivers seat belt switch indicates whether the driver seat is buckled or unbuckled.
