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 the GM part number that is stored within the sensing and diagnostic module (SDM) memory.

Calibration ID: The scan tool displays the calibration ID, which is the check sum of the SDM read only memory contents.

Component Serial Number: The scan tool displays the SDM component serial number that is stored within the SDM.

Driver Side Belt Status: The scan tool displays whether the driver seat belt is buckled or unbuckled.

Ignition Voltage: The scan tool displays 0-20 volts. This is the system voltage measured by the SDM between the ignition input and ground.

Julian Date of Build: This number represents the day of the year that the module was built.

Left SIS ID: The scan tool displays the driver side impact sensor (SIS) ID that is sent to the SDM when the ignition is turned ON.

Passenger Seat Belt Status: The scan tool displays whether the driver seat belt is buckled or unbuckled.

PROM ID: The scan tool displays the programmable read-only memory (PROM) ID.

Right SIS ID: The scan tool displays whether the passenger SIS ID that is sent to the SDM when ignition is turned ON.

VIN Information: The scan tool displays a list. The body control module (BCM) is programmed in the assembly plant with the last four digits of the SDM part number and the VIN of the vehicle.
