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 SDM memory.

Calibration ID
- The scan tool displays a 4-digit number. This calibration ID is the check sum of the SDM read only memory contents.

Component Serial Number
- The scan tool displays a 4-digit number. This number is the SDM serial number.

Driver Belt Status Changed This Ignition Cycle
- The scan tool displays Yes or No. Driver seat belt has been buckled or unbuckled after the ignition is turned ON.

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.

Front End Sensor 1 ID
- The scan tool displays a 2-digit ID number. The ID signal is sent to the SDM from the left front end sensor.

Front End Sensor 2 ID
- The scan tool displays a 2-digit ID number. The ID signal is sent to the SDM from the right front end sensor.

Ignition 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.

ROM ID
- The scan tool displays a 4-digit number. This number is the read-only memory (ROM) ID.

VIN Information
- The scan tool displays a list. The Dash Integration Module (DIM) is programmed in the assembly plant with the last four digits of SDM part number and the VIN of the vehicle.

Year Module Built
- The scan tool displays what year the module was built.
