  2. PRECAUTIONS WHEN USING INTELLIGENT TESTER


    1. When using the intelligent tester to troubleshoot the smart entry and start system:

      Connect the intelligent tester to the DLC3 while the engine switch is off, and turn a door courtesy light switch on and off at intervals of 1.5 seconds until communication between the tester and vehicle begins.

    2. After all DTCs are cleared, check if the malfunction occurs again 6 seconds after the engine switch is turned on (IG).

  3. PRECAUTIONS FOR EACH FUNCTION


    1. Precautions for the key:

      The key is a precision instrument. Be sure to observe the following:


      1. Do not drop or strike the key.

      2. Do not keep the key in a high temperature area for a long time.

      3. Do not use an ultrasonic washing machine to clean the key.

      4. Keep the key away from magnets or magnetized items during use.

      5. Do not attach any stickers to the key.

      6. If the key is lost, delete all registered key ID codes and then reregister the remaining keys.

    2. Precautions for the entry unlock function:


      1. As the sensor is built into the backside of the door outside handle assembly, the user must touch the backside of the handle when performing the unlock function.

      2. If touched with gloved hands, the response of the door may be delayed.

      3. During the entry unlock operation, if the door handle is pulled before the door unlocks, the unlock function cannot be completed. Confirm that the door has been unlocked before pulling the door outside handle assembly to open the door.

      4. Make sure that the doors are unlocked when touching the touch sensor on the door outside handle assembly while the key is being carried.

        If the doors cannot be unlocked, the certification ECU (smart key ECU assembly) orders the main body ECU to perform the door unlock operation 4 times at intervals of 0.75 seconds.

        At this time, if the handle is being pulled, the door cannot be unlocked due to mechanical reasons.

        Be sure to return the door handle to its original position.

        If the door cannot be opened by pulling the handle, perform the entry unlock operation again.

      5. If the key is too close to the oscillator on the outside of the vehicle, the door may not be unlocked because the key cannot react to the strong wave output from the transmitter.

      6. If the key is within the vehicle exterior detection area, the door can be unlocked even when a person other than the person carrying the key holds the door handle.

        However, the doors other than the door that the codes match will not be unlocked.

        (If the key is within the driver side door detection area outside the vehicle, the doors will be unlocked when a person carrying the key holds the driver side door handle. However, if any door handle other than that of the driver side door is held, the doors will not be unlocked.)

      7. If a door is not opened after the door unlock operation, the doors automatically lock after approximately 30 seconds.

      8. If a large amount of water is applied to the door handle due to a car wash or heavy rain and the key is within the vehicle exterior detection area, the doors may be unlocked.

        However, the doors will be locked again after approximately 30 seconds if a door is not opened.

      9. If the key of the smart entry and start system is used while it is being carried with the key of another smart entry and start system, the time before the entry unlock operation will become longer than usual. This is not a malfunction.

    3. Precautions for the entry lock function:


      1. When performing the entry lock operation, firmly press the lock switch on the front door outside handle assembly.

        If pressed too quickly or lightly, the entry lock may not operate.

      2. It is possible that signals output from the indoor electrical key oscillator may leak through the window. Also, if the key is too close to a door electrical key oscillator, the oscillator output signals are too strong and the key cannot respond. As a result, when the key is near the vehicle interior (window or door handle), the entry lock function may not operate. Also, the key reminder warning buzzer may sound and the entry lock operation may stop functioning. In this situation, move the key away from the vehicle interior (window or door handle), and perform the entry lock and entry unlock operations.

      3. Do not touch the lock switch while opening or closing the door.

        If the lock switch is pressed when opening or closing the door while the key is being carried, the door ajar warning buzzer* sounds (beeps outside the vehicle for 5 seconds).

      4. If the key is on the instrument panel, rear package tray, floor or in the glove box, the key may not be detected, causing the key reminder function not to operate. As a result, the key may be accidentally locked in the vehicle. Always carry the key.

      5. If the key is outside the vehicle but is very close to a window or door handle (the ECU determines that the key is inside the vehicle) and the transmitter or mechanical key is used to lock the doors (entry lock is not used), entry unlock will not operate. To unlock the doors, perform a wireless door unlock operation. The entry lock function operates in this way to prevent the user from unintentionally unlocking the doors from outside the vehicle. For example, when a user operates the wireless door lock operation from inside the vehicle, radio waves from a door electrical key oscillator may leak into the vehicle interior and the doors may unlock.

      6. To allow the user enough time to check if the doors are locked after performing a door lock operation (entry lock function or wireless door lock operation), the entry unlock function will not be permitted for 3 seconds after the door lock operation.

    4. Precautions for the battery built into the key and the vehicle battery:


      1. The key is constantly checking for signals from the vehicle, which requires power from the built-in battery of the key. The life of the battery is approximately 1 to 2 years depending on the usage conditions. Be sure to replace the battery when its power is low. When replacing the battery, do not touch the inner circuit board or other inner parts.

      2. The key is constantly checking for signals from the vehicle and using battery power, whether the key is being used or not. Even if the user is carrying 2 keys and only 1 key is used, both keys will consume battery power.

      3. The key receives radio waves at approximately 314 MHz. If the key continuously receives strong and identical frequency waves, this may drain the key battery. Store the key at least 1 m (3.28 ft.) from TVs, personal computers or other electrical products.

      4. When the doors are locked, the vehicle battery is used to transmit radio waves. The battery will be discharged if the vehicle remains stopped for a long time. If the vehicle is not to be used for a long time, remove the battery from the vehicle or cancel the smart entry and start system.

      5. When the doors are locked and the key is in the detection area of a door electrical key oscillator, the battery is used for regular communication between the key and vehicle. If the vehicle is not being used, keep the key away from the vehicle (more than 2 m (6.56 ft.)).

      6. After disconnecting and reconnecting the battery cable, the entry unlock function may not operate. If this occurs, perform a wireless door unlock and lock operation.

    5. Precautions for the back door entry unlock function:

      Even if the key is within the outside electrical key oscillator (for rear side) detection area, the back door cannot be opened if the key is in the following areas:


      • Near the center of the bumper

      • Too close to the ground or in a high place
