  2. CUSTOMER PROBLEM ANALYSIS


    • When 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. INSPECT BATTERY VOLTAGE


    1. Measure the battery voltage.

      Standard voltage
      11 to 14 V

      Tech Tips

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

  4. CHECK CABIN


    1. Check that condensation is not likely to occur in the cabin and that the temperature is not high or extremely low in the cabin.

      OK
      Condensation is not likely being produced and the temperature is not high or extremely low.

      Tech Tips


      • A humid cabin and a rapid change in temperature may lead to condensation. Condensation in the cabin may cause a short circuit.

      • The audio and visual system may not operate normally when the temperature is -20°C (-4°F) or lower, or 65°C (149°F) or higher.
