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 the GM part number that is stored within the SDM memory.

ADS A/D: The scan tool displays the auxiliary discriminating sensor (ADS) signal input into the SDM. The scan tool will always display 20 volts because the ADS monitoring is disabled.

ADS Monitoring: The scan tool displays whether the ADS monitoring is enabled or disabled.

Calibration ID: The scan tool displays the calibration ID, which is the check sum of the SDM read only memory contents.

Component Serial Number: The scan tool displays the SDM component serial number that is stored within the SDM.

Driver Frontal Loop: The scan tool displays whether the inflatable restraint steering wheel module 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 the driver SIS ID that is sent to the SDM when the ignition is turned ON.

Driver Side Loop: The scan tool displays whether the inflatable restraint side impact module-LF deployment loop is enabled or disabled.

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

Lamp in Current State: The scan tool displays the number of cycles that the AIR BAG indicator has been turned ON.

Passenger Frontal Loop: The scan tool displays whether the inflatable restraint I/P module deployment loop is enabled or disabled.

Passenger Side Impact Sensor ID: The scan tool displays the passenger SIS ID that is sent to the SDM when the ignition is turned ON.

Passenger Side Loop: The scan tool displays whether the inflatable restraint side impact module-RF deployment loop is enabled or disabled.

PROM ID: The scan tool displays the programmable read-only memory (PROM) ID.

Warning Lamp ON/OFF Timer: The scan tool displays the time, in minutes, that the AIR BAG indicator has been turned ON.

Year Module Built: The scan tool displays what year the module was built.
