Initial Inspection and Diagnostic Overview

DIAGNOSTIC STARTING POINT

Begin diagnosis with the Diagnostic System Check - Vehicle in Vehicle DTC Information. The Diagnostic System Check will provide the following information:
- The identification of the control modules which command the system
- The ability of the control modules to communicate through the serial data circuit
- The identification of any stored diagnostic trouble codes (DTCs) and their status

This cruise system has self diagnostic capabilities and can display a diagnostic flash code when prompted. Refer to Diagnostic Trouble Code (DTC) Displaying and Diagnostic Trouble Code (DTC) Clearing for further information.
