Entry & Start System (Entry Function): Precautions

Notes on replacing the ECM
CAUTION: When replacing the collation ECM (smart key ECM ASSY), it is also necessary to prepare all the electrical key transmitter SUB-ASSYs.
1. When you replace the ID code box (immobilizer code ECM)*, collation ECM (smart key ECM ASSY), steering lock actuator ASSY (steering lock ECM), the ECM, or the electrical key transmitter SUB-ASSY, refer to the "Registration manual for immobilizer".
  *: The ID code box is included.
2. If you replace the collation ECM (smart key ECM ASSY), the registered steering lock position will not match the one registered in the steering lock actuator ASSY (steering lock ECM). Due to this, you might not be able to start the engine. To avoid this, you need to perform the following steps after replacing the collation ECM (smart key ECM ASSY):
  1. Move the shift lever in position P*.
    *: for automatic transmission
  2. With the power mode in IG OFF, open and then close a door, and start the engine.
Notes for registration
1. When replacing any of the following parts, refer to the "Registration manual for immobilizer".
  1. ID code box (immobilizer code ECM)*
  2. Collation ECM (smart key ECM ASSY)
  3. Steering lock actuator ASSY (steering lock ECM)
  4. Electrical key transmitter SUB-ASSY *: The ID code box is included.
Notes on removing the cable from the battery ground terminal
1. If you disconnect the battery cable and then reconnect it afterwards, the entry unlock function might not work. In this case, the entry unlock function returns by performing the wireless door lock and unlock.
Notes on the vehicle battery and the battery integrated into the electrical key transmitter SUB-ASSY
1. While doors are locked, radio waves are transmitted from the vehicle, which means that power is constantly supplied from the battery. If the vehicle is left in this state for a prolonged period of time, the battery can become completely drained. If the vehicle is not to be used for a long time, the battery must be disconnected, or the entry & start system (entry function) must be cancelled.
  NOTE: To cancel the entry & start system (entry function), refer to the steps described below. (Refer to CUSTOMIZE PARAMETERS )
2. If the doors are locked and the electrical key transmitter SUB-ASSY is located within the detection area of the electrical key antenna, there is regular communication between the electrical key transmitter SUB-ASSY and the vehicle, causing battery output. If the vehicle is not in use, the electrical key transmitter SUB-ASSY must be kept outside a 2 m (6.56 feet) radius of the vehicle.

Notes on inspecting the entry & start system (entry function)
1. General notes on the entry & start system (entry function)
  1. Always carry the electrical key transmitter SUB-ASSY with you.
2. Under the conditions described below, the key detection area might become smaller, or the electrical key transmitter SUB-ASSY might not be detected properly. These problems arise when the reception of electromagnetic waves used for key detection becomes weak.
  1. The battery is drained.
  2. There is a facility that produces strong radio waves nearby, such as a TV tower, a power plant, a TV station, or a gas station.
  3. The electrical key transmitter SUB-ASSY is carried along with a wireless communication device, such as a transceiver, a cell phone, a cordless telephone, a digital audio player, or a portable game system.
  4. The electrical key transmitter SUB-ASSY is located under a metal object such as a coin or a special type of a card, or is in contact with such an object.
  5. A metal film is applied over the rear glass of the vehicle.
  6. A radio wave type keyless entry system is being used nearby.
  7. A vehicle using an electrical key transmitter SUB-ASSY is located nearby.
  8. The electrical key transmitter SUB-ASSY is located near a device producing high voltage or electrical noise.
  9. The electrical key transmitter SUB-ASSY is near an electronic device, such as a charger.
3. The operating range of the entry & start system (entry function):
  1. Due to the design of the body, there are certain places where the system might not work properly.
  2. Even when the electrical key transmitter SUB-ASSY is located within the key detection area outside the vehicle, it might not be detected properly if it is used near the window, the outer door handle, or the center of the bumper.
  3. Even when the electrical key transmitter SUB-ASSY is located within the key detection area inside the vehicle, it might not be detected properly if it is located on the instrument panel, inside the accessory box of the instrument panel, inside or near the front cup holder, inside the glove compartment, on the package tray trim, or on the floor.
  4. If held improperly, the electrical key transmitter SUB-ASSY may not work properly.
4. If using a pacemaker, it may affect the pacemaker. If this might be the case, the instruction manual supplied with the pacemaker must be consulted carefully.
  1. The entry & start system (entry function) does not work under the following circumstances:
    1. The entry & start system (entry function) is being cancelled.
    2. Electrical key transmitter SUB-ASSY
      The battery is drained (the LED on the electrical key transmitter SUB-ASSY does not blink when the switch is pressed).
Notes on the entry unlock function
1. When you perform an entry unlock operation, make sure to touch the unlock sensor located on the back side of the front door outer handle ASSY.
2. Touching the unlock sensor located on the back side of the front door outer handle ASSY wearing a glove or the like could result in slow system response.
3. After performing an entry unlock operation, confirm that the door has been unlocked and open it by pulling the front door outer handle ASSY.
4. If you approach the vehicle too quickly or pull the front door outer handle ASSY too quickly, you might fail to open the door. In this case, return the front door outer handle ASSY to its original position, then pull it again. The door will then open. (If the system could not detect the unlock operation, it will automatically repeat the unlock operation 4 times.)
5. If you move the electrical key transmitter SUB-ASSY to the front door outer handle ASSY too quickly, you might fail to unlock the door by the entry unlock function.
6. While the electrical key transmitter SUB-ASSY is located within the detection area outside the vehicle, a door can be unlocked by anyone (even those who do not hold the electrical key transmitter SUB-ASSY) who grabs the front door outer handle ASSY. Note that the unlock operation works only on a door for which a code match is detected. (While the electrical key transmitter SUB-ASSY is located within the detection area outside the driver's door, grabbing the driver's side front door outside handle ASSY unlocks the door, but grabbing the passenger's side front door outside handle ASSY does not unlock the door.)
7. If you do not open the door after unlocking it, the door will be automatically locked in approximately 30 seconds.*
  NOTE: *: If the door is automatically locked after an elapse of a certain period of time from the entry unlock operation performed with the electrical key transmitter SUB-ASSY located near the vehicle, the electrical key transmitter SUB-ASSY will be detected as being inside the vehicle. As a result, the lockout protection function kicks in to unlock the door.
8. If a large amount of water is sprinkled over the front door outer handle ASSY during car wash, heavy rain, or the like when the electrical key transmitter SUB-ASSY is located inside the detection area outside the vehicle, the sensor or the entry unlock function might become activated. If, however, a door is not opened within 30 seconds, it will be locked automatically.*
  NOTE: *: If the door is automatically locked after an elapse of a certain period of time from the entry unlock operation performed with the electrical key transmitter SUB-ASSY located near the vehicle, the electrical key transmitter SUB-ASSY will be detected as being inside the vehicle. As a result, the key lock-in prevention function kicks in to unlock the door.
9. If the electrical key transmitter SUB-ASSY is carried along with an electrical key transmitter SUB-ASSY of another vehicle supporting an entry & start system, it might take longer than usual to unlock a door by an entry unlock operation.
Notes on the entry lock function
1. If you touch the front door outer handle ASSY too quickly during an entry lock operation, you might fail to lock the door.
2. If the electrical key transmitter SUB-ASSY is brought near the vehicle (near the window or the front door outer handle ASSY), the entry lock function might not work. In addition, the anti-lockout alarm might go off, disabling the entry unlock operation. If this is the case, move the electrical key transmitter SUB-ASSY away from the vehicle (the window or the front door outer handle ASSY) and perform an entry lock operation.
3. If you carry the electrical key transmitter SUB-ASSY and if you attempt to lock any door while it is open (not properly closed), a warning will be activated to remind you that the door is open.
4. If the electrical key transmitter SUB-ASSY is placed on the instrument panel, inside the glove compartment, or on the floor, the anti-lockout alarm (which reminds you that the electrical key transmitter SUB-ASSY is left inside the vehicle) might not go off. In this case, you can end up locking the door with the electrical key transmitter SUB-ASSY left inside the vehicle. Make sure to always carry the electrical key transmitter SUB-ASSY with you.
5. After locking a door using an entry lock or wireless lock operation, you have to wait approximately 3 seconds before you can perform an entry unlock operation.
