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
-
The scan tool displays the SDM serial number.
- 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.
- Front End Sensor 1 ID
-
The scan tool displays a 2 - digit ID number. The ID signal sent to the SDM from the front end sensor.
- Front End Sensor 2 ID
-
The scan tool displays a 2 - digit ID number. The ID signal 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.
- Passenger Seat Belt Status
-
The scan tool displays Buckled or Unbuckled. The signal from the passengers seat belt switch indicates whether the passenger seat is buckled or unbuckled, for Rendezvous only.
- 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 Body Control Module (BCM) 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.
