MULTI CHANNEL FUNCTION
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.
| *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 7 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 channels 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 channels.
| *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 channels will not be switched. | The channels will be switched. | The channels will not be switched. | The channels will be switched*. |
*: The channels are not switched during vehicle interior verification after an entry lock operation is performed.
BASIC PRECAUTIONS
DTCs and Data Lists of ECUs related to the entry and start system can be checked using the GTS.
Check for DTCs using the following procedure. If any DTCs are output, diagnose those DTCs first.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Body Electrical / Entry&Start, Power Source Control or Starting Control / Trouble Codes.
When using the GTS with the power switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.
If the entry and start system has been canceled by a customize setting, enable the entry and start system.

DIAGNOSIS IN ACCORDANCE WITH USER OPERATION
Operation 1
| Operation | Turn the power 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) and rear 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 (N54-17 (CLG1) - I1-18 (E)*) |

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 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. |

|
| 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. |
Operation 4
| Operation | After getting into the vehicle while carrying the electrical key transmitter sub-assembly, close the door and press the power switch once with the shift lever in P while not depressing the brake pedal. |
| Expected operation of the vehicle |
If any of the preceding do not happen, check the suspected areas in the following table. Tech Tips When the power switch is pressed, the indoor electrical key antennas form the key detection area inside the vehicle and detect 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 LED of the electrical key transmitter sub-assembly illuminates for a short time. After pressing the power 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 entry warning light is displayed on the multi-information display in the combination meter assembly. After the power source mode has changed, and L code and S code verification has been completed, the parking lock will be unlocked and the immobiliser will be disabled. The Data List item "Immobiliser" will then change from "Set" to "Unset". Signal transmission: Certification ECU (smart key ECU assembly) → Indoor electrical key antenna → Electrical key transmitter sub-assembly → Electrical key and tire pressure monitoring system receiver assembly → Certification ECU (smart key ECU assembly) Tech Tips The interior detection area is formed when any of the following conditions are met:

AUXILIARY BATTERY SAVING FUNCTION
When the entry and start system is operating, the vehicle performs key detection operations every 0.25 seconds. Therefore, if the vehicle is left as is for a long period of time, the auxiliary battery may become fully discharged. The following controls help reduce the rate at which the battery is discharged.
If the entry and start system is not operated for 5 days or more, periodic signal transmission from the electrical key antennas stops. However, the doors can still be unlocked by touching the unlock sensor of a front door outside handle assembly.
If the entry and start system is not operated for 14 days or more, the lock and unlock sensors of the front door outside handle assembly (for front passenger door) will be disabled. Therefore, only the unlock sensor of the front door outside handle assembly (for driver door) can be used to unlock the doors.
If 10 minutes or more elapse while the electrical key transmitter sub-assembly is in an exterior detection area, the front door outside handle assembly (electrical key antenna) detecting the electrical key transmitter sub-assembly will stop operating.
To restore operation of the entry and start system, perform any of the following operations.
While carrying the electrical key transmitter sub-assembly, touch the lock or unlock sensor of the front door outside handle assembly (for driver door) and perform a door lock or unlock operation.
Lock or unlock the doors using the wireless function.
Insert the mechanical key into the door key cylinder of the driver door and lock or unlock the doors.
