Scan Tool Data Definitions

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 the SDM serial number.

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

Driver Seat Belt A/D: The scan tool displays 0 or 12 volts. If driver seat belt is buckled = 12 volts, unbuckled = 0 volts.

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.

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.

Manufacture Shift Code: The scan tool displays a 1-digit number. This number indicates what shift built this module.

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.

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

VIN Information: The scan tool displays a list. The DIM (Dash Integration Module) 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.
