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.

PSIR Suppression: The scan tool displays Enabled/Disabled. The signal from the SDM indicates whether the inflatable restraint IP module switch is in the ON or OFF position.

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 serial number of the SDM.

Driver Frontal Loop: The scan tool displays Enabled/Disabled. The signal from the SDM indicates whether the driver frontal loop is enabled or disabled.

Driver Side 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.

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 number represents the day of the year that the module was built.

Passenger Frontal Loop: The scan tool displays Enabled/Disabled. The signal from the SDM indicates whether the passenger frontal loop is enabled or disabled.

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.
