The SIR scan tool data definitions contain a brief description of all SIR related parameters available on the scan tool. The parameters that are available on the scan tool are listed below in alphabetical order.

8-Digit GM Part Number: The scan tool displays an 8-digit part number. This number is the GM part number that is stored within the sensing and diagnostic module (SDM) memory.
Battery Voltage: The scan tool displays 0-20 volts. The Ignition represents the system voltage measured by the SDM at its ignition feed.
Calibration ID: The scan tool displays a 4-digit number. This calibration ID is the check sum of the SDM read only memory contents.
Driver Seat 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.
Driver Side Impact Sensor ID: The scan tool displays a 2-digit ID number. The ID signal is sent to the SDM from the Driver SIS.
Electronic Front End Sensor ID: The scan tool displays a 2-digit ID number. The ID signal is sent to the SDM from the front end sensor.
Battery Voltage: The scan tool displays 0-20 volts. The Ignition represents the system voltage measured by the SDM at its ignition feed.
Julian Date of Build: This displays the day of the year the module was built.
Passenger Side Impact Sensor ID: The scan tool displays a 2-digit ID number. The ID signal is sent to the SDM from the Passenger SIS.
Passenger Seat Belt Status: The scan tool displays Buckled or Unbuckled. The signal from the passengers seat belt switch indicates whether the passenger seat is buckled or unbuckled.
ROM ID: The scan tool displays a 4-digit number. This number is the read-only memory (ROM) ID.
Year Module Built: The scan tool displays what year the module was built.
