  4. MULTI CHANNEL FUNCTION


    1. The electrical key transmitter sub-assembly and door control receiver can operate on two different RF channels. When an electrical key transmitter sub-assembly is brought within an exterior detection area, key verification begins. If key verification fails due to wave interference, the channel will be switched and key verification will be performed again.

      The multi channel system begins verification using the channel on which the last verification was successfully performed. When verification fails, the system switches to the other channel.

      Text in Illustration
      *a Exterior detection areas are created using LF waves (emitted from the vehicle at intervals of 0.25 seconds) to receive a response from the electrical key transmitter sub-assembly.
      *b When the electrical key transmitter sub-assembly is brought into an exterior detection area, it receives LF waves from the vehicle. Using RF waves, the electrical key transmitter sub-assembly responds to the vehicle.
      *c Upon receiving the response from the electrical key transmitter sub-assembly, the certification ECU (smart key ECU assembly) activates the electrical key antennas (outside) one by one. Using LF waves, the certification ECU (smart key ECU assembly) determines which exterior detection area the electrical key transmitter sub-assembly is in.
      *d The electrical key transmitter sub-assembly receives the LF waves from the vehicle and responds using RF waves. (The certification ECU (smart key ECU assembly) recognizes which exterior detection area the electrical key transmitter sub-assembly is in.)
      *e The certification ECU (smart key ECU assembly) sends registered key ID information to the electrical key transmitter sub-assembly using LF waves. (Up to 4 key IDs can be registered.)
      *f The electrical key transmitter sub-assembly sends the key ID information using RF waves on both channels. When the certification ECU (smart key ECU assembly) receives it, verification completes.
      *g Wave interference (Channel switching)

      The multi channel system changes the channels when the RF band (*b, *d) is interrupted by wave interference.

  5. DIAGNOSIS IN ACCORDANCE WITH USER OPERATION


    1. Operation 1

      Operation

      Turn the engine switch off and lock all the doors, then take the electrical key transmitter sub-assembly approximately 3 m (9.84 ft.) or more away from the vehicle.

      Tech Tips

      The detection area of each electrical key antenna (outside) is formed by emitting a periodic LF band request signal every 0.25 seconds. The detection area formed by each front door outside handle assembly (electrical key antenna) has a detection range of approximately 0.7 m (2.30 ft.).

      Suspected Area Diagnosis
      Electrical key transmitter sub-assembly

      • The key ID code sent by the electrical key transmitter sub-assembly does not match the key ID code stored in the certification ECU (smart key ECU assembly). Use another electrical key transmitter sub-assembly to check the operation.

      • If the LED of the electrical key transmitter sub-assembly does not blink when it is brought within 0.7 m (2.30 ft.) of the driver door, perform the following procedure.

        Press the lock and unlock buttons of the electrical key transmitter sub-assembly to check the operation. If the doors can be locked and unlocked, that means the detection area has not been formed. Parts other than the electrical key transmitter sub-assemblies and door control receiver may be malfunctioning.

      • If the electrical key transmitter sub-assembly malfunctions, the engine cannot be started and the engine switch cannot be turned on (ACC or IG). Under normal operation, the smart warning light in the combination meter assembly blinks green when the engine switch is pressed with the electrical key transmitter sub-assembly in the driver seat, the shift lever in P*1 or N*2 and the brake pedal*1*2 or clutch pedal*3 not depressed. If the door cannot be opened, use the mechanical key installed in the electrical key transmitter sub-assembly to open the door.

      Tech Tips

      Before replacing the electrical key transmitter sub-assembly, check if the transmitter battery is depleted.
      Transmitter battery is depleted

      • Press and hold the lock switch of the electrical key transmitter sub-assembly for 5 seconds and check the number of times that the transmitter LED blinks. If the transmitter LED does not blink or blinks only once or twice, the transmitter battery may be depleted. If the transmitter LED does not blink at all, the electrical key transmitter sub-assembly may be malfunctioning.

      • If the transmitter battery voltage before the electrical key transmitter sub-assembly sends a signal drops to 2.7 V or less, "Yes" is displayed for "Key Low Battery" in the Data List.

      • If the transmitter battery voltage drops to 2.2 V or lower, operation cannot be assured.

        Tech Tips

        The output of the electrical key transmitter sub-assembly will decrease if it is in low temperatures.

      • When the transmitter battery is depleted, the engine cannot be started and the engine switch cannot be turned on (ACC or IG). If the electrical key transmitter sub-assembly is held near the engine switch the engine can be started.

      • Make sure that the transmitter battery type and installation direction are correct.
      Wave Interference

      • If the problem occurs in certain locations or times of day, the possibility of wave interference is high.

      • When the electrical key transmitter sub-assembly is malfunctioning, the transmitter battery is depleted, an electrical key transmitter sub-assembly from another vehicle has been used or wave interference is suspected. "Yes" may be displayed for any of the following Data List items: "Unmatched Vehicle-ID", "No Response", "Unmatch Code or Form" or "ID Code Difference(Resp)"
      Certification ECU (smart key ECU assembly) -

      Vehicle exterior detection area is not formed properly.


      • If the electrical key transmitter sub-assembly LED does not blink within 0.7 m (2.30 ft.) of the front door outside handle assembly of the driver door, but blinks within 0.7 m (2.30 ft.) of the front passenger door, the front door outside handle assembly of the driver door may be malfunctioning.

      • Even if the vehicle exterior detection area is not formed properly, the engine switch can be turned on (ACC) and the engine can be started.

      • Formation of the vehicle exterior detection area can be confirmed by using the intelligent tester. Click here.

      • Even if the vehicle exterior detection area is not formed properly, the doors can be unlocked by pressing the unlock button of the electrical key transmitter sub-assembly.
      Door control receiver

      • If the door control receiver is malfunctioning, it is not possible to unlock the front passenger door.

      • If the door control receiver is malfunctioning, it is not possible to unlock the doors by a wireless unlock operation.

      • If the door control receiver is malfunctioning, the engine cannot be started and the engine switch cannot be turned on (ACC or IG) unless in an emergency.

      • Formation of the vehicle exterior detection area can be confirmed by using the intelligent tester. Click here.
      Vehicle battery is discharged It may be possible to tell whether the vehicle battery is discharged by operating the horn.
      Others

      • If the smart key function has been cancelled through the customize function, the detection area cannot be formed, therefore the electrical key transmitter sub-assembly LED will not blink even if the electrical key transmitter sub-assembly is brought near a front door outside handle assembly.

      • In the entry and start system, if the electrical key transmitter sub-assembly is constantly in the exterior detection area of one of the doors, the transmitter battery could be drained. For this reason, if this state continues longer than 10 minutes, the entry and start system automatically deactivates the exterior detection area that the electrical key transmitter sub-assembly is in.

      • If the electrical key transmitter sub-assembly is left in the vehicle and the doors are locked using another electrical key transmitter sub-assembly, the electrical key transmitter sub-assembly LED will not blink even if it is brought near a front door outside handle assembly.

    3. Operation 3

      Operation Touch the unlock sensor of the driver door with the electrical key transmitter sub-assembly in the exterior detection area.
