HINT: 

• The safety connect system provides a variety of functions. Therefore, it is important to identify whether a malfunction is related to the communication system, including radio wave conditions, or any other systems. Carefully check the conditions that caused the malfunction in order to determine if a temporary problem with the radio wave signal conditions caused the malfunction.
• In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
• Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
• The following 5 items are important points for analysis:

  What	Vehicle model, system name
  When	Date, time, occurrence frequency
  Where	Road conditions
  Under what conditions?	Driving conditions, weather conditions
  How did it happen?	Problem symptoms

   DTCs are not output.	B

   HINT: 

   • Even if the problem symptom is not confirmed, check for DTCs. This is because the system stores history DTCs.
   • If more information is needed, perform a recheck using the "System Check Mode" screen after rechecking for DTCs using the Techstream.
   • Check for DTCs and inspect the area that the code indicates.
