The scan tool data lists contain all of the cruise control related parameters that are available on the scan tool used for the cruise control system. The data list column indicates the location of the parameter within the scan tool menu selections.
Use the scan tool data lists as directed by a diagnostic table or in order to supplement the diagnostic procedures. Begin all of the diagnostic procedures with Diagnostic System Check - Vehicle .
Use the Scan Tool Data List only after the following is determined:
| • | There is no published DTC procedure nor published symptom procedure for the customer concern. |
| • | DTC procedure and symptoms diagnostic procedures indicated in the system check fail to solve the customers problems. |
The typical data values are obtained from a properly operating vehicle under conditions specified in the first row of the Scan Tool Data List table. Compare the values obtained from the troublesome vehicles with the typical data, you may find where the trouble is.
