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? Running conditions, driving conditions, weather conditions How did it happen? Problem symptoms* *: 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. If the entry lock/unlock function does not operate for all doors. If the entry lock function does not operate. If the entry unlock function does not operate. If both the entry lock and unlock functions do not operate. If the wireless lock and unlock functions do not operate. If there is no power even when the engine switch is pressed [does not turn on (ACC)]. If the engine does not start with the entry ignition function. If the outside warning buzzers do not sound. If the customer attempted to start the engine by touching the electrical key to the engine switch and pressing the engine switch. If the interior warning buzzers do not sound. If the steering does not unlock. Any other details concerning the problem. If it is thought 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. 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.). Specific times when the system does not operate: Whether or not symptoms occurred immediately after purchase or only recently. Whether or not the symptoms occurred even when the key was near the vehicle (electrical key antenna). If the system does not operate only when near specific vehicles (there may be an effect from electric waves from the wireless systems of other vehicles). If the system operates intermittently. If the key is bundled together with other items. If the key is carried together with other electronic devices, such as cell phones, personal computers, portable music players, other electrical keys, etc. (keep the key at least 0.1 m (0.33 ft.) away from such items).
