HINT: 

• 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 problem 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

1. Measure the battery voltage with the ignition switch off.

   Standard voltage

   11 to 14 V

   HINT: 

   If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

2. Check the fuses and relays.
3. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

1. Using the GTS, check for Vehicle Control History (RoB).

   HINT: 

   Based on the customer interview results, narrow down the cause of the malfunction and check the related Vehicle Control History (RoB).

   Chassis > Front Recognition Camera > Utility 

   Tester Display
   Vehicle Control History (RoB)

2. Make a note of the output Vehicle Control History (RoB).
