2. CUSTOMER PROBLEM ANALYSIS

   Tech Tips

   
   

   • 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

3. PRE-CHECK

   
   

   1. Measure the auxiliary battery voltage with the power switch off.

      Standard voltage
      11 to 14 V

      If the voltage is below 11 V, recharge or replace the auxiliary 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.

      Tech Tips

      If the vehicle approaching speaker controller mistakenly receives a vehicle speed signal, communication between the vehicle and the GTS fails. Be sure to check "Vehicle Speed Meter" displayed on the Data List to make sure that the vehicle speed is not abnormal.
