    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.).

      Waveform or output value Pulse generation (D41-12 (CLG1) - D48-11 (GND)*)

    2. Operation 2

      Operation

      Bring the electrical key transmitter sub-assembly within 0.7 m (2.30 ft.) of the driver door.

      Tech Tips

      The system is in unlock standby mode when the electrical key transmitter sub-assembly is in the detection area and the key ID code sent by the electrical key transmitter sub-assembly matches the key ID code stored by the certification ECU (smart key ECU assembly). The door unlocks if the unlock sensor is touched by hand with the system in unlock standby mode.

      Signal transmission: Certification ECU (smart key ECU assembly) → Front door outside handle assembly (electrical key antenna) → Electrical key transmitter sub-assembly → Door control receiver → Certification ECU (smart key ECU assembly) → Main body ECU (network gateway ECU))

      Expected operation of the vehicle The electrical key transmitter sub-assembly LED starts blinking. If it does not, any of the parts listed in the table below may be malfunctioning.
      Waveform or output value
      • Pulse generation (D41-12 (CLG1) - D48-11 (GND)*)

      • Pulse generation (D40-17 (RDA) - D48-11 (GND)*)

      • Pulse generation (D40-19 (RSSI) - D48-11 (GND)*)


      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 and the brake pedal*1 or clutch pedal*2 not depressed.

        • *2: for Manual Transmission

      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 2.4 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 GTS. 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 GTS. 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.

      • The smart warning light in the combination meter assembly blinks green slowly, and the engine switch is turned on (ACC).

      • The steering wheel is unlocked.

      If it does not, the parts listed below may be malfunctioning.

      Tech Tips

      When the engine switch is pressed, the indoor electrical key oscillator forms a key detection area inside the vehicle and detects the electrical key transmitter sub-assembly in the cabin. The electrical key transmitter sub-assembly sends the ID code upon receiving a request signal and the electrical key transmitter sub-assembly LED illuminates for a short time. After pressing the engine switch, if the key ID code sent by the electrical key transmitter sub-assembly matches the key ID code stored by the certification ECU (smart key ECU assembly), the ACC relay turns on and the smart warning light in the combination meter assembly blinks green slowly. Then after the power source mode has changed, L code and S code*3 verification has been completed, the steering wheel will be unlocked and the immobiliser will be inactive. Then the Data List status of "Immobiliser" will be changed from "Set" to "Unset".
