  2. CUSTOMER PROBLEM ANALYSIS

    Tech Tips


    • In troubleshooting, in order to check the problem symptoms accurately and judge correctly, avoid having any preconceptions. 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 malfunctions 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 and time, frequency, whether the problem occurred recently or has been occurring for a long time
      Where Whether the problem occurs at specified place
      Under what conditions? Whether the doors were locked or unlocked, whether the power switch was on (IG), whether the hybrid control system was started
      How did it happen? Ask the customer for details about the vehicle operating conditions, environment and malfunction.*

      • *: Be sure to ask the customer in detail about the following points concerning the vehicle operating conditions, environment and problem, and then check for DTCs.


        1. If the entry unlock function does not operate.

        2. If there is no power even when the power switch is pressed (does not turn on (ACC)).

        3. If the entry lock function does not operate.

        4. If the entry lock/unlock function does not operate for all doors.

        7. If the hybrid control system does not start with the push-button start function.

        8. If a hybrid control system start was attempted by holding the electrical key transmitter sub-assembly near the power switch and then pressing the power switch.

        9. If the interior warning buzzers do not sound.

        10. If the outside warning buzzers do not sound.

        11. If the steering does not unlock.

      • If it is suspected that wave interference is likely, be sure to ask the customer in detail about the following points concerning the vehicle operating conditions, environment and problem.


        1. Specific locations where the system does not operate (such as near TV towers, large video displays, wireless garage door opener systems, wireless security cameras, home security systems, etc.).

        2. Specific times when the system does not operate.

        3. If the symptoms occurred immediately after purchase or only recently.

        4. If the system does not operate only when near specific vehicles (there may be wave interference from the wireless systems of other vehicles).

        5. If the system operates intermittently.

        6. If the electrical key transmitter sub-assembly is bundled together with other items.

        7. If the electrical key transmitter sub-assembly is carried together with other electronic devices, such as cell phones, personal computers, portable music players, other electrical key transmitter sub-assemblies, etc. (keep the electrical key transmitter sub-assembly at least 0.1 m (0.328 ft.) away from such items).

        8. Where the electrical key transmitter sub-assembly is being kept when not in use: If the electrical key transmitter sub-assembly is being placed within 1 m (3.28 ft.) of items such as TVs, DVD recorders, induction cookers, rice cookers, dishwashers, modems, cell phones, personal computers, microwave ovens, desk or floor lamps, cordless telephones, etc.

        9. If there are electronic devices that transmit radio waves placed in the vehicle.
