Scan Tool Data List
The SIR Scan Tool Data List contains all restraint system related parameters that are available on the scan tool. The parameters in the list are arranged in alphabetical order. The column "Data List," indicates the location of the parameter within the scan tool menu selections.
Use the SIR Scan Tool Data List as directed by a diagnostic table or to supplement the diagnostic procedures. Begin all of the diagnostic procedures with the Diagnostic System Check - SIR. Refer to the Diagnostic System Check - SIR . Use the SIR Scan Tool Data List after determining the following:
- There are no published DTC procedures nor published symptom procedures for the customer concern.
- The DTC or symptom diagnostic procedure indicated by the Diagnostic System Check - SIR 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.
