The SIR scan tool data list and PPS scan tool data list contain the restraint system related parameters that are available on the scan tool. 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 in order to supplement the diagnostic procedures. Begin all of the diagnostic procedures with the Diagnostic System Check - Vehicle. Use the Scan Tool Data Lists after the following is determined: Initial Inspection and Diagnostic Overview
* A diagnostic directs the use of the Data List.
* There is no published diagnostic trouble code (DTC) procedure nor published symptom procedure for the customer concern.
* The DTC or symptom diagnostic procedure indicated by the 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 second 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.
