MULTI CHANNEL FUNCTION

The electrical key transmitter sub-assembly and certification ECU (smart key ECU 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. If the verification fails, the system switches to the other channel.

*a	Exterior detection areas are created using LF waves 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. When the certification ECU (smart key ECU assembly) receives it, verification completes.
*g	Wave interference (Channel switching)	-	-

The multi channel system changes the channel when the RF band (*b, *d and *f) is interrupted by wave interference. Refer to the table below to confirm when the system changes the channel.


	b or d is NG		*f is NG
Condition	RF waves cannot be received	RF waves cannot be received properly	RF waves cannot be received	RF waves cannot be received properly
Channel switching	The channel will not be switched.	The channel will be switched.	The channel will not be switched.	The channel will be switched*.

*: The channel is not switched during vehicle interior verification after an entry lock operation is performed.

DIAGNOSIS IN ACCORDANCE WITH USER OPERATION

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.

Operation 2


Operation	While carrying the electrical key transmitter sub-assembly, press the trigger switch on the front door outside handle assembly. Tip: When the trigger switch is pressed, a request signal is sent from the indoor electrical key antenna, and an approximately 0.7 m (2.30 ft.) detection area is formed to detect the electrical key transmitter sub-assembly. Signal transmission: Certification ECU (smart key ECU assembly) → No. 2 indoor electrical key antenna assembly (center pillar LH) and No. 2 indoor electrical key antenna assembly (center pillar RH) → Electrical key transmitter sub-assembly → Certification ECU (smart key ECU assembly) → Body ECU
Expected operation of the vehicle	While the doors are unlocked, the answer-back is performed at the same time. If the answer-back is not performed at the same time any of the parts listed in the table below may be malfunctioning.

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. 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 "Certification ECU (smart key ECU assembly)" may be malfunctioning. If the electrical key transmitter sub-assembly is malfunctioning, the engine cannot be started and the engine switch cannot be turned on (ACC) or on (IG). Under normal conditions, the smart warning light in the combination meter assembly blinks (green) slowly when the engine switch is pressed with the electrical key transmitter sub-assembly in the driver seat area, the shift lever in N1 and the brake pedal1 or clutch pedal released*2. Tip: If the door cannot be unlocked, use the mechanical key built into in the electrical key transmitter sub-assembly to unlock 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 2.2 V or less, Yes is displayed for the Data List item Key Low Battery. If the transmitter battery voltage drops to 2.0 V or lower, operation cannot be assured. Tip: 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 on (IG) normally. 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. If 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)	If the certification ECU (smart key ECU assembly) is malfunctioning, it is not possible to unlock the front passenger door. If the certification ECU (smart key ECU assembly) is malfunctioning, wireless unlock cannot be performed. If the certification ECU (smart key ECU assembly) is malfunctioning, the engine switch cannot be turned on (ACC) and the engine cannot be started (excluding emergency operation). Formation of the vehicle exterior detection area can be confirmed by using the GTS. Click here
No. 2 indoor electrical key antenna assembly (center pillar LH) No. 2 indoor electrical key antenna assembly (center pillar RH)	Vehicle exterior detection area is not formed properly. 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 Under normal conditions, "ON" is displayed for the Data List item "D-Door Trigger Switch" when the trigger switch is pressed.
Front door outside handle assembly (for driver door)	If the doors can be unlocked by pressing the trigger switch of the front passenger door while carrying the electrical key transmitter sub-assembly, the trigger switch of the driver door may be malfunctioning.
Vehicle Battery is discharged	It may be possible to tell whether the vehicle battery is discharged by operating the horn.
Door lock/unlock mechanism	If a door cannot be locked/unlocked by operating the door control switch on the door in the cabin, the door lock mechanism is malfunctioning.
Others	If the entry and start system function has been canceled through the customize function, the detection area will not be formed and the door lock function will not operate even if the trigger switch is pressed. If the electrical key transmitter sub-assembly is in transmitter battery saving mode, even if it receives LF waves from the vehicle, it does not respond using RF waves, therefore the electrical key transmitter sub-assembly LED does not blink.

Operation 3


Operation	After getting into the vehicle while carrying the electrical key transmitter sub-assembly, close the door and press the engine switch once with the shift lever in N1 while not depressing the brake pedal1 or clutch pedal*2.
Expected operation of the vehicle	The smart warning light in the combination meter assembly blinks (green) slowly, and the engine switch is turned on (ACC). The steering is unlocked. If any of the above operations are not performed, check the suspected areas in the following table. Tip: When the engine switch is pressed, the indoor electrical key antenna 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 a key 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. After the power source mode has changed and L code verification has been completed, the steering will be unlocked and the immobiliser will be inactive. The Data List status of "Immobiliser" will then be changed from "Set" to "Unset". Signal transmission: Certification ECU (smart key ECU assembly) → Indoor electrical key antenna assembly → Electrical key transmitter sub-assembly → Certification ECU (smart key ECU assembly) Tip: The interior detection area is formed when any of the following conditions are met: Any door is opened. Within approximately 30 seconds after any of the doors have been opened and closed. Within approximately 30 seconds after the brake1 or clutch pedal2 has been depressed. Right after the engine switch is pressed.
