FUNCTION
Start Function
The start function has different power source modes to suit the brake pedal condition and shift lever position*1 or clutch pedal condition*2.
When the driver carrying an electrical key transmitter sub-assembly enters the vehicle while the power source mode is off and presses the engine switch without depressing the brake pedal*1 or the clutch pedal*2, the power source mode turns on (ACC) to show "POWER ON" on the multi-information display*3 or key warning light will blink green*4. With each pressing of the engine switch, the power source mode switches as follows: off → on (ACC) → on (IG) → off.
When the driver who is carrying an electrical key transmitter sub-assembly enters the vehicle while the power source mode is off, and depresses the clutch pedal*2 or depresses the brake pedal while the shift lever is in P or N*1, the key warning display*3 illuminates or the key warning light*4 illuminates green. Pressing the engine switch with the key warning display*3 or key warning light*4 illuminated will cause the engine to start.
When starting the engine with the vehicle stopped, pressing the engine switch while the shift lever is in P will cause the power source mode to turn off. Pressing the engine switch when the shift lever is in any position other than P will cause the mode to turn on (ACC).*1
When starting the engine with the vehicle stopped, pressing the engine switch will cause the power source mode to turn off.*2

Figure 2. Transition of Power Source Mode (Models with Manual Transaxle)
Transition of the power source mode when the electrical key transmitter sub-assembly battery is low or the electrical key transmitter sub-assembly is not operating normally due to an electromagnetic interference:
The driver uses the mechanical key (which is built into the electrical key transmitter sub-assembly) to unlock the door, and enters the vehicle while carrying the electrical key transmitter sub-assembly.
The driver places the TOYOTA mark of the electrical key transmitter sub-assembly in contact with the front of the engine switch (push start switch) while depressing the brake pedal*1 or clutch pedal*2 to turn to on (IG or ACC*3).
With each pressing of the engine switch (push start switch), the power source mode switches as follows: on (ACC)*3 → on (IG) → off.

Note
Normally, the operation of the engine switch (push start switch) is disabled while the vehicle is being driven. However, if the engine must be stopped in an emergency while the vehicle is in motion, the driver can press the engine switch (push start switch) for approximately 2 seconds or more, or press it briefly for 3 times or more in succession to stop the engine.
If no signals are transmitted to the certification ECU (smart key ECU assembly) due to a malfunction in the stop light switch assembly, the engine will not start even if the driver presses the engine switch (push start switch) while depressing the brake pedal.*1 In this case, the driver can start the engine by the following operations. Press the engine switch (push start switch) to turn the power source mode from off to on (ACC), and press the engine switch (push start switch) again and hold it for 15 seconds or more.
The above 2 operations must be applied only in emergency situations. Under normal conditions, the engine must not be stopped by pressing the engine switch (push start switch) during driving or started without depressing the clutch pedal*2 or brake pedal when the shift lever is in any position other than P*3.

SYSTEM CONTROL
Entry Function
The entry function consists of the following functions:
| Function | Outline |
|---|---|
| Wireless Door Lock Control | This function is a convenient system for locking and unlocking all the doors and the back door at a distance. The operation of this function in the entry and start system is the same as that of the wireless door lock control system. However, the receiver in the certification ECU (smart key ECU assembly) uses a door control receiver to perform the control. |
| Entry Illumination | When an electrical key transmitter sub-assembly enters the exterior actuation area of the door electrical key antenna, the interior light and engine switch illumination light will illuminate. |
| Entry Unlock | When an electrical key transmitter sub-assembly is located in the exterior actuation area of a door electrical key antenna, touching any unlock sensor will cause all doors to unlock. In addition, the back door can be unlocked by pressing the opener switch. |
| Entry Lock | When an electrical key transmitter sub-assembly is located in the exterior actuation area of any door electrical key antenna or electrical key antenna (back door) and the engine switch (push start switch) is off, all doors can be locked by simply touching the lock sensor or pressing the back door lock switch. |
| Back Door Open | When an electrical key transmitter sub-assembly is in an exterior actuation area of the electrical key antenna (back door), the back door can be opened manually by simply pressing the back door opener switch. |
| Prevention of Key Confinement | Prevents the confinement of the electrical key transmitter sub-assembly if the door is locked from the door outside handle while the electrical key transmitter sub-assembly is still inside the vehicle. When locking the doors while the electrical key transmitter sub-assembly is inside the vehicle, a buzzer sounds to prevent the electrical key transmitter sub-assembly from being confined, and all doors are automatically unlocked. |
| Key Cancel |
|
| Battery Saving | To prevent the electrical key transmitter sub-assembly battery and the vehicle battery from becoming discharged, the battery saving function activates when the vehicle remains unused for a long period of time or the electrical key transmitter sub-assembly has been detected in the exterior actuation area for more than 10 minutes. |
| Warning | The entry and start system causes the certification ECU to sound the buzzer in the combination meter assembly and uses the multi-information display*1 or key warning light*2 in order to alert the driver. |
| Key Code Registration Function | A total of 7 keys can be registered. Key registration enables the registering (writing and storing) of transmitter recognition codes in the EEPROM that is contained in the certification ECU (smart key ECU assembly). |

Driver door is closed.
Driver door is unlocked.
The operation procedure is as follows:
Unlock once with the unlock button of the key.
Open the driver door within 5 seconds.
Unlock twice with the unlock button of the key within 5 seconds.
Repeat open → close twice for the driver door, and open again. (Driver door: open → close → open → close → open)*
Unlock twice with the unlock button of the key*
Repeat open → close once for the driver door, and open again. (Driver door: open → close → open)*
Close the driver door within 5 seconds.
When key cancel is activated, the wireless door lock buzzer sounds twice.
To return to the original condition, perform the procedures again. When key cancel is returned, the wireless door lock buzzer sounds once.
*: Perform all these 3 steps within 30 seconds of the previous step.
Key Code Registration Function
The table below shows the 4 special ID code registration function modes through which up to 4 different codes can be registered. The codes are electronically registered (written and stored) in the EEPROM. For details of the recognition code registration procedure, refer to the Service Bulletin.
| Mode | Function |
|---|---|
| Registration | Registers newly received codes. This mode is used whenever the certification ECU (smart key ECU assembly) is replaced. |
| Addition | Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter. If the number of codes exceeds 4, the oldest registered code is cleared first. |
| Confirmation | Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist. |
CONSTRUCTION
Electrical Key Transmitter Sub-assembly
The electrical key transmitter sub-assembly consists of a mechanical key, transmitter for the wireless door lock control, transceiver for the entry function, and transponder chip for the engine immobiliser function.
This mechanical key operates the driver door lock cylinder, but cannot be used to start the engine.
The transceiver in the electrical key transmitter sub-assembly receives the signals from the antennas and returns the ID code of the electrical key transmitter sub-assembly to the door control receiver.
The transponder chip for the engine immobiliser function returns a signal to the engine switch as a response to the radio wave received from the engine switch.

| *3 | Mechanical Key | - | - |
Door Control Receiver
The door control receiver and electrical key transmitter sub-assembly can operate on 2 different Radio Frequency (RF) channels. Therefore, stable signal transmission and reception will be delivered even if wave interference occurs.
When an electrical key transmitter sub-assembly is brought within an exterior actuation 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.
| Step | System Operation |
|---|---|
| *a | Exterior actuation areas are created using Low Frequency (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 actuation 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 actuation 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 actuation 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 on both channels. 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 and *d) is interrupted by wave interference.
Combination Meter Assembly
The key warning light located in the combination meter helps the driver in checking the current status of the power source. (models with monochrome type multi-information display)
| *A | Models with Toyota Safety Sense | *B | Models without Toyota Safety Sense |
| *1 | Key Warning Light | - | - |

When the certification ECU (smart key ECU assembly) detects an abnormality with the entry and start system, a message appears on the multi-information display. If the engine is stopped in this state, it might not be possible to restart it. (models with color type multi-information display)
| *1 | Multi-information Display | *2 | Power Source State |
| *3 | Key Warning Light | - | - |
| Displayed Item | Power Source Condition |
|---|---|
| - | Either of the following conditions is met:
|
| Power Source State | On (ACC) state or On (IG) state* |
| Key Warning Light | Engine start ready state* |
*: The engine is not started.
Tech Tips
Engine start ready state is shown below:
For models with CVT, the shift lever is in P, the key certification result is OK and the brake pedal is depressed (the stop light switch assembly is on).
For models with manual transaxle, the key certification result is OK and the clutch pedal is depressed (the clutch start switch assembly is on).
DIAGNOSIS
The certification ECU (smart key ECU assembly) can detect malfunctions in the start function when the power source mode is on (IG).
The indicator light warning continues for 15 seconds even when the power source mode is turned off.
The Diagnostic Trouble Code (DTC) can be read by connecting the Global TechStream (GTS) to the DLC3.
The start function cannot be operated again if a malfunction occurs.
