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

Driver Side Belt Status: The scan tool displays Buckled or Unbuckled. The signal from the driver 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 1 ID: The scan tool displays a 2 digit ID number. The ID signal is sent to the SDM from the front end sensor.

Electronic Front End Sensor 2 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: The scan tool displays a 3 digit number. Which represents the day of the year the module was built.

Manufacture Shift Code: The scan tool displays a 4 digit number.

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.

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