   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 front door outside handle assemblies may be malfunctioning. If the electrical key transmitter sub-assembly malfunctions, the EV control system cannot be started and the power switch cannot be turned on (ACC or IG). Under normal operation, when the power switch is pressed with the electrical key transmitter sub-assembly in the driver seat, the shift lever in P and the brake pedal not depressed. HINT:  If the door cannot be opened, use the mechanical key installed in the electrical key transmitter sub-assembly to open the door. 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 at the time the electrical key transmitter sub-assembly sends a signal drops to 2.1 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 EV control system cannot be started and the power switch cannot be turned on (ACC or IG). If the electrical key transmitter sub-assembly is held near the power switch the EV 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)	-
   Front door outside handle 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 power switch can be turned on (ACC) and the EV control system can be started. Formation of the vehicle exterior detection area can be confirmed by using the Techstream. Refer to OPERATION CHECK . 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 EV control system cannot be started and the power 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 Techstream. Refer to OPERATION CHECK .
   Vehicle Auxiliary Battery is discharged	It may be possible to tell whether the vehicle auxiliary battery is discharged by operating the horn.
   Others	If the smart key system 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 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 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 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
