SIR 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.

ADS Enabled:The scan tool displays whether the Auxiliary Discriminating Sensor is enabled or not.

Driver Side Belt Status:The scan tool displays whether the driver seat belt is buckled or unbuckled.

Driver Side Loop Status:The scan tool displays whether the driver side air bag deployment loop is within the normal operating voltage range.
Use the SIR scan tool data list after the following is determined:
^ There is no published DTC procedure nor published symptom procedure for the customer concern.
^ The DTC or symptom diagnostic procedure indicated by the SIR diagnostic system check does not resolve the customer concern.

The typical data values are obtained from a properly operating vehicle under the conditions specified in the first row of the scan tool data list table. Comparison of the parameter values from the suspect vehicle with the typical data values may reveal the source of the customer concern.

Ignition voltage:The scan tool displays 0 - 20 volts. This is the system voltage measured by the SDM between the ignition input and ground.
Passenger Side Loop Status:The scan tool displays whether the passenger side air bag deployment loop is within the normal operating voltage range.

Warning Lamp Cycles:The scan tool displays the number of cycles that the air bag warning indicator has been turned ON.

Warning Lamp ON:The scan tool displays the time, in minutes, that the air bag warning indicator has been turned ON.
