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 component serial number.
Driver Frontal Loop: The scan tool displays whether the driver frontal air bag deployment loop is enabled or disabled.
Driver Side Belt Status: The scan tool displays whether the driver seat belt is buckled or unbuckled.
Driver Side Impact Sensor ID: The scan tool displays a 2 digit number. This is the driver SIS ID that is sent to the SDM when the ignition is first turned ON. Ignition Voltage: The scan tool displays 0 - 20 volts. This is the system voltage measured by the SDM between the ignition input and ground.
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.
Lamp in Current State: The scan tool displays the number of cycles that the air bag warning lamp has been turned ON.
Passenger Frontal Loop: The scan tool displays whether the passenger frontal air bag deployment loop is enabled or disabled.
Passenger Side Belt Status: The scan tool displays whether the passenger seat belt is buckled or unbuckled.
Passenger Side Impact Sensor ID: The scan tool displays a 2 digit number. This is the passenger SIS ID that is sent to the SDM when the ignition is first turned ON.
PROM ID: The scan tool displays a 4 digit number. This number is the programmable read - only memory (PROM) ID.
Warning Lamp ON/OFF Time: The scan tool displays the time, in minutes, that the air bag warning lamp has been turned ON.
Year Module Built: The scan tool displays what year the module was built.
