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 #8-11: The scan tool displays digits 8 through 11 of the SDM serial number.
Component Serial #12: The scan tool displays digit 12 of 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 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 sent
to the SDM from the Driver SIS.
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. An example would be 723.
723 is July 23 which is day 204 based on the Julian Calendar.
Passenger Side Impact Sensor ID: The scan tool displays a 2 digit ID number. The ID signal 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.
