Scan Tool Data Definitions

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

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.
Electronic Front End Sensor ID: The scan tool displays a 2-digit ID number. The ID signal sent to the SDM from the EFS (also known as Front Discriminating 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 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 Powertrain Control Module (PCM) 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.
