Door Lock - Smart Key System
DOOR LOCK: SMART KEY SYSTEM: PRECAUTION
1. PRECAUTION FOR DISCONNECTING THE BATTERY CABLE
NOTICE:
When disconnecting the battery negative(-) terminal, initialize the following systems after the terminal is reconnected:
2. PRECAUTIONS WHEN USING TECHSTREAM
(a) When troubleshooting the smart key system using Techstream with the engine switch off, connect Techstream to the vehicle and repeat turning any of the courtesy light switches on and off until communication between the tester and the vehicle begins (the interval between ON and OFF should be less than 1.5 seconds).
(b) After DTCs are all cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).
3. PRECAUTIONS FOR EACH FUNCTION
(a) Precautions for the electrical key:
The electrical key is a precision instrument. Be sure to observe the following:
(1) Do not drop or strike the electrical key.
(2) Do not keep the electrical key in a high temperature area for a long time.
(3) Do not use an ultrasonic washing machine to clean the electrical key.
(4) Keep the electrical key away from magnets or magnetized items during use.
(5) Do not attach any stickers to the electrical key.
(6) If an electrical key is lost, delete all registered electrical key ID codes and then reregister the remaining electrical keys.
(b) Precautions for the entry unlock function:
(1) As the sensor is built into the backside of the door outside handle, the user must touch the backside of the door outside handle when performing the unlock function.
(2) If the backside of the door outside handle is touched with gloved hands, the response of the door may be delayed.
(3) During the entry unlock operation, if the door outside 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 to open the door.
(4) Make sure that the doors are unlocked when touching the touch sensor on the door outside handle while the electrical key is being carried.
If the doors cannot be unlocked, the certification ECU (smart key ECU assembly) orders the main body ECU (instrument panel junction block) to perform the door unlock operation 4 times at intervals of 0.75 seconds.
At this time, the door may not be unlocked because the door outside handle is being pulled due to some mechanical reasons.
Be sure to return the door outside handle to its original position.
If the door cannot be opened by pulling the door outside handle, perform the entry unlock operation again.
(5) If the electrical key is too close to the oscillator on the outside of the vehicle, the door may not be unlocked because the electrical key cannot react to the strong wave output from the transmitter.
(6) If the electrical key is within the vehicle exterior detection area, the door can be unlocked even when a person other than the person carrying the electrical key holds the door outside handle.
However, the doors other than the door that the codes match will not be unlocked.
(If the electrical key is within the driver side door's detection area outside the vehicle, the doors will be unlocked when the person carrying the electrical key holds the driver side door outside handle. However, if any door outside 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 outside handle due to a car wash or heavy rain, the electrical key being within the vehicle exterior detection area may cause the doors to be unlocked.
However, the doors will be locked again after approximately 30 seconds if a door is not opened.
(9) If the electrical key of the smart key system is used while it is being carried with the electrical key of another smart key system, the time before the entry unlock operation will become longer than usual. This is not a malfunction.
(c) Precautions for the entry lock function:
(1) When performing the entry lock operation, firmly press the lock switch on the door outside handle.
If the lock switch is pressed too quickly or lightly, the entry lock may not operate.
(2) It is possible that signals output from the indoor electrical key antenna may leak through the window. Also, if the electrical key is too close to a door electrical key oscillator, the oscillator output signals are too strong and the electrical key cannot respond. As a result, when the electrical key is near the vehicle interior (window, door outside handle), the entry lock function may not operate. Also, the electrical key reminder warning buzzer may sound and the entry unlock operation may stop functioning. In this situation, move the electrical key away from the vehicle interior (window, door outside handle), perform the entry lock operation and perform the entry unlock operation.
(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 electrical key is being carried, the door ajar warning buzzer sounds (beeps outside the vehicle for 10 seconds).
(4) If the electrical key is on the instrument panel, rear package tray, floor, or in the glove box, the electrical key reminder function may not operate and the electrical key may be locked in the vehicle. Always carry the electrical key.
(5) If the electrical key is outside the vehicle but is very close to a window or door outside handle (the ECU determines that the electrical 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.
(d) Precautions for back door or glass hatch entry open function:
Even if the electrical key is within the outside electrical key oscillator (back door) detection area, the back door or glass hatch cannot be opened if the electrical key is in the following areas:
* Near the center of the bumper
* Too close to the ground or in a high place
(e) Precautions for the function to prevent electrical key confinement in the cabin:
(1) Do not place the electrical key in the cabin.
If the luggage compartment is closed with the electrical key in it when all the doors are locked, the alarm to indicate electrical key confinement will operate (beeping sound for 2 seconds outside of the vehicle). However, the alarm may not operate for some reason relating to the electrical key location, the electrical key condition (covered with metal or near metal), or ambient radio waves.
(2) If the glass hatch is closed with the electrical key in the luggage compartment when any of the doors is unlocked or open, the electrical key confinement prevention function will not operate. In this case, use the glass hatch opener in the cabin to open the glass hatch and take out the electrical key.
(3) The alarm may erroneously operate in the following conditions. If you can confirm that you are carrying the electrical key or that the electrical key is in the cabin, there is no problem. The entry glass hatch open function may not operate if the alarm erroneously operates. In this case, use the glass hatch opener in the cabin.
- The electrical key is brought into the cabin after the glass hatch is opened, and then the glass hatch is closed.
- The glass hatch is closed by the person who is carrying the electrical key.
(4) If the alarm operates when the glass hatch is closed with all the doors locked, the electrical key is in the cabin. Check the cabin to find the electrical key.
(5) If the glass hatch is closed with the electrical key in the luggage compartment when all the doors are locked, the alarm will sound and the glass hatch can be opened. This may increase the risk of the vehicle being stolen.
(6) Do not open or close the glass hatch after all the doors are locked if you want to keep the spare electrical keys in the cabin. As a result, the alarm may sound and the glass hatch can be opened. This may increase the risk of the vehicle being stolen.
(f) Precautions for the battery built into the electrical key and the vehicle battery:
(1) The electrical key is constantly checking for signals from the vehicle, which requires power from the electrical key's built-in battery. 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 electrical key is constantly checking for signals from the vehicle using battery power to determine whether the electrical key is being used or not. Even if the user is carrying 2 electrical keys and only 1 electrical key is used, both electrical keys will consume battery power.
(3) The electrical key receives radio waves at approximately 314 MHz. If the electrical key continuously receives strong, identical frequency waves, this may drain the electrical key's battery. Store the electrical key at least 1 m (3.3 ft.) away from TVs, personal computers, or other electrical products.
(4) When a door is being locked, the vehicle battery is used to transmit radio waves. The battery may be dead if the vehicle remains stopped for a long time. If the vehicle is not used for a long time, remove the battery from the vehicle or cancel the smart key system.
(5) When a door is being locked with the electrical key in the detection area of a door electrical key oscillator, the battery is used for regular communication between the electrical key and vehicle. If the vehicle is not used, keep the electrical key away from the vehicle (more than 2 m (6.6 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.
(g) Precautions for the entry unlock mode switching function:
(1) Use the entry unlock mode switching function within a 1 m (3.3 ft.) area around the vehicle.
(2) The entry unlock mode switching function cannot be used within 5 seconds of the previous mode change. Wait 5 seconds or more before performing a mode change.
