System Description [07/2020 - ]

1. The electrical key transmitter sub-assembly and electrical key and tire pressure monitoring system receiver assembly 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.

1. Some customers may inquire about the frequency used by the smart key system on various models. This repair manual contains the applicable specifications of the smart key system.

HINT:  The system will enter in unlock standby mode when the electrical key transmitter sub-assembly is brought into 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) → Door outside handle assembly (electrical key antenna) → Electrical key transmitter sub-assembly → Electrical key and tire pressure monitoring system receiver assembly → Certification ECU (smart key ECU assembly) → Main body ECU (multiplex network body ECU)
   Expected operation of the vehicle	The LED of the electrical key transmitter sub-assembly starts blinking. If it does not, check the suspected areas in the following table.
   Waveform or Output Value	Pulse generation (N54-17 (CLG1) - I1-18 (E)*) Pulse generation (N54-18 (RCO) - I1-18 (E)*) Pulse generation (N54-19 (RDAM) - I1-18 (E)*) Pulse generation (N54-20 (CSEL) - I1-18 (E)*)

   1. *: Refer to TERMINALS OF ECU [09/2016 - ] 

   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 front door outside handle assembly (for driver door), perform the following procedure. Press the lock and unlock switches 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 electrical key and tire pressure monitoring system receiver assembly may be malfunctioning. If the electrical key transmitter sub-assembly is malfunctioning, the hybrid control system cannot be started and the power switch cannot be turned on (ACC) or on (IG). Under normal conditions, the entry warning light is displayed on the multi-information display in the combination meter assembly when the power switch is pressed with the electrical key transmitter sub-assembly in the driver seat area, the park (P) and the brake pedal released. If the driver door cannot be opened, use the mechanical key installed in the electrical key transmitter sub-assembly to open the door. HINT:  Before replacing the electrical key transmitter sub-assembly, check if the transmitter battery is depleted. If the driver door cannot be opened, use the mechanical key installed in the electrical key transmitter sub-assembly to open the door.
   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 LED of the electrical key transmitter sub-assembly blinks. If the LED of the electrical key transmitter sub-assembly does not blink or blinks only once or twice, the transmitter battery may be depleted. If the LED of the electrical key transmitter sub-assembly does not blink at all, the electrical key transmitter sub-assembly may be malfunctioning. If the transmitter battery voltage at the time the electrical key transmitter sub-assembly sends a signal drops to 2.2 V or less, "Yes" is displayed for "Key Low Battery" in the Data List. If the transmitter battery voltage drops to 2.0 V or lower, operation cannot be assured. HINT:  The output of the electrical key transmitter sub-assembly will decrease if it is in low temperatures. When the transmitter battery is depleted, the power cannot be started and the power switch cannot be turned on (ACC) or on (IG). If the electrical key transmitter sub-assembly is held near the power switch, the hybrid control system 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: "Unmatch Code or Form", "No Response", "ID Code Difference" or "Unmatched Vehicle-ID"
   Certification ECU (smart key ECU assembly)	-
   Main body ECU (multiplex network body ECU)	-
   Front door outside handle assembly	Vehicle exterior detection area is not formed properly. 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 front door outside handle assembly (for driver door), but blinks when it is brought within 0.7 m (2.30 ft.) of the front door outside handle assembly (for 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 power switch can be turned on (ACC) and the hybrid control system can be started. Formation of the vehicle exterior detection area can be confirmed by using the Techstream. Refer to OPERATION CHECK [09/2016 - ]  Even if the vehicle exterior detection area is not formed properly, the doors can be unlocked by pressing the unlock switch of the electrical key transmitter sub-assembly.
   Electrical Key and Tire Pressure Monitoring System Receiver Assembly	If the electrical key and tire pressure monitoring system receiver assembly is malfunctioning, it is not possible to unlock the front passenger door. If the electrical key and tire pressure monitoring system receiver assembly is malfunctioning, it is not possible to unlock the doors by a wireless unlock operation. If the electrical key and tire pressure monitoring system receiver assembly is malfunctioning, the hybrid control system cannot be started and the power switch cannot be turned on (ACC) or on (IG) unless in an emergency. Formation of the vehicle exterior detection area can be confirmed by using the Techstream. Refer to OPERATION CHECK [09/2016 - ]
   Auxiliary battery is discharged	It may be possible to tell whether the auxiliary battery is discharged by operating the horn.
   Others	If the smart key system function has been canceled through the customize function, the detection area cannot be formed, therefore the LED of the electrical key transmitter sub-assembly will not blink even if the electrical key transmitter sub-assembly is brought near a front door outside handle assembly. In the smart key 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 for longer than 10 minutes, the smart key system automatically deactivates the exterior detection area that the electrical key transmitter sub-assembly is in. If the electrical key transmitter sub-assembly is in transmitter battery saving mode, even if it receives LF waves from the vehicle, it will not respond using RF waves, therefore the LED of the electrical key transmitter sub-assembly will not blink. 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 LED of the electrical key transmitter sub-assembly 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 front door outside handle assembly (for driver door) with the electrical key transmitter sub-assembly in the exterior detection area.
   Expected operation of the vehicle	While the doors are unlocked, the answer-back is performed at the same time. If they do not, check the suspected areas in the following table.
   Waveform or Output Value	Pulse generation (N54-17 (CLG1) - I1-18 (E)*) Tester connection (instrument panel junction block assembly (ACT-) - body ground)*
