Answer

Brief Explanations:

When the check - engine light is illuminated, the first step is to use a scan tool to retrieve Diagnostic Trouble Codes (DTCs) which will help identify the root cause of the problem. Shutting down and restarting may not accurately diagnose the issue. Just noting or marking the light in vehicle - related sections does not address the problem.

Answer:

A. Use a scan tool to retrieve DTCs
