  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

  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.

      Tip:

      • 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.
