The electronic suspension control (ESC) scan tool data list contains all the electronic suspension control 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 ESC 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. Use the ESC scan tool data list only after the following is determined:

The typical scan tool data values are an average of the displayed values recorded from normally operating vehicles. The typical scan tool data values are intended to represent what a normally functioning system would display with certain preliminary settings. The values you get may vary slightly due to a low battery charge or other reasons. But the values should be very close.

Use only the parameters listed in the tables for diagnosis. If a scan tool reads other parameters, the values are not recommended for use in diagnosis. Refer to Scan Tool Data Definitions for further detailed information.

The scan tool's input display function can be helpful in determining if the electronic suspension control (ESC) module is receiving the correct input status. This can assist in determining if the ESC system is actually commanding a suspension damper solenoid.

A scan tool may be used in order to command the suspension damper solenoids and SERVICE RIDE CONTROL message ON or OFF. This can be very helpful in determining if a certain portion of a circuit or a component is in working order. The following tests are available under the Special Functions selection. The following can be commanded ON or OFF:
