HINT: 

• 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 ignition switch was ON, whether the hybrid control system was starting
  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 to ACC).
    3. If the entry lock function does not operate.
    4. If the entry lock/unlock function does not operate for all doors.
    5. If both the entry lock and unlock functions do not operate.
    6. If the wireless lock and unlock functions do not operate.
    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.
  • 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.
    10. When the transmitter battery was last replaced. The transmitter battery can be checked roughly using the "Key Low Battery" item in the Data List.

        Refer to DATA LIST / ACTIVE TEST [12/2023 - ] 

    11. If the customer installed any optional components (theft deterrent devices, wireless fog lights, etc.) to the vehicle.

1. Measure the auxiliary battery voltage.

   Standard voltage

   11 to 14 V (ignition switch off)

   HINT: 

   • A simple method to determine whether the auxiliary battery is depleted is to operate the horn.
   • If the auxiliary battery voltage is below 11 V, recharge or replace the auxiliary battery.
2. Check for blown fuses, open or shorted wire harnesses, improperly connected connectors and other problems in areas that can be visually inspected.
3. Check the connections of each connector and check them for deformation or damage.
