OPERATION
The special functions of the entry and start system only work when the key is in the actuation area formed by the 6 oscillators.
The indoor electrical key oscillator (front), indoor electrical key oscillator (center), and indoor electrical key oscillator (rear) form the interior actuation area.
The door electrical key oscillator LH, door electrical key oscillator RH, and outside electrical key oscillator form the exterior actuation area.
| Actuation Area | Detail |
|---|---|
| Interior | The interior actuation area of the indoor electrical key oscillators (front, center, rear) is formed when the driver door is opened or closed, when the power switch is pushed, when a warning is activated, or when the lock sensor is on. |
| Exterior | The exterior actuation area formed by the door electrical key oscillators (LH, RH) and outside electrical key oscillator (back door) is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of the front doors, or the center of the rear bumper. |
| Around Front Doors | The exterior actuation area of the door electrical key oscillators (LH, RH) is formed by transmitting a request signal every 0.25 seconds while the power switch is off and each door is locked. In this way it detects the presence of a key. When locking the door using the lock sensor on the outer door handle, the actuation area is formed when the lock sensor is touched. |
| Around Back Door | The exterior actuation area of the outside electrical key oscillator (back door) is formed when the back door opener switch is on. |

Note
Normally, the operation of the power switch is disabled while the vehicle is being driven. However, in an emergency, by pushing the power switch 3 times or more in a row or pushing the power switch for approximately 2 seconds or more, the driver can stop the hybrid control system while the vehicle is in motion.
If no signals are transmitted to the power management control ECU due to malfunctions in the stop light switch or shift lever position sensor, the hybrid control system may not start when the power switch is pushed with the brake pedal depressed. In such cases, performing the following procedure may enable the hybrid control system to start: 1) push the power switch to turn the power source from off to on (ACC), and 2) push the power 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 hybrid control system must not be stopped by pushing the power switch while driving or should not be started without depressing the brake pedal or when the shift lever is in any position except P or N.
Pattern A: Off → READY (Hybrid control system is started)
| Step | System Operation |
|---|---|
| (1) | The driver, carrying the key, enters the vehicle. |
| (2) | When the brake pedal is depressed with the following conditions satisfied, the power management control ECU recognizes the stop light switch signal and transmits the key certification request to the certification ECU (smart key ECU assembly):
|
| (3) | The certification ECU (smart key ECU assembly) receives the certification request and transmits a request signal to the oscillators (front, center, rear). These oscillators then form an actuation area. |
| (4) | The moment the key receives the request signal, it transmits its ID code to the door control receiver. The signal includes the response code. |
| (5) | The door control receiver receives this code and transmits it to the certification ECU (smart key ECU assembly). |
| (6) | The certification ECU (smart key ECU assembly) judges and certifies the ID code, and transmits a key certification OK signal to the power management control ECU. |
| (7) | Due to the brake pedal being depressed, the power management control ECU turns on the green indicator light of the power switch. |
| (8) | The driver pushes the power switch once, while the green indicator light of the power switch is illuminated. |
| Step | System Operation |
|---|---|
| (9) | After receiving the key certification OK signal, the power management control ECU turns on the ACC relay, and then turns on the IG1 and IG2 relays. |
| (10) | The certification ECU (smart key ECU assembly) checks that the power source has turned from off to on (IG), and transmits a steering unlock signal to the power management control ECU and ID code box (immobiliser code ECU). |
| (11) | The power management control ECU receives the steering unlock signal and supplies power to the steering lock ECU. |
| (12) | The steering lock ECU receives the steering unlock signal via the ID code box (immobiliser code ECU), and releases the steering lock. |
| (13) | After checking the steering unlock condition, the certification ECU (smart key ECU assembly) transmits an engine immobiliser disengage signal to the certification ECU and ID code box (immobiliser code ECU). |
| (14) | The ID code box (immobiliser code ECU) certifies the disengage signal of the certification ECU (smart key ECU assembly), transmits the engine immobiliser disengage signal to the power management control ECU, and disengages the engine immobiliser. |
| Step | System Operation |
|---|---|
| (15) | After checking that the steering is in the unlocked condition, the power management control ECU start the hybrid control system. |
| (16) | The power management control ECU checks that the hybrid control system has started and turns off the indicator light of the power switch. |
Pattern B: Off → On (ACC) → On (IG) → Off
| Step | System Operation |
|---|---|
| (1) | The driver, carrying the key, enters the vehicle. |
| (2) | When the power switch is pushed once with the following conditions satisfied, the power management control ECU recognizes the power switch signal and transmits the key certification request to the certification ECU (smart key ECU assembly)
|
| (3) | The rest of the system operation is the same as (3) to (6) in pattern A. |
| (4) | The power management control ECU turns on the ACC relays will turn on the amber indicator light of the power switch. |
| (5) | The rest of the system operation is the same as (10) to (14) in pattern A. |
| Step | System Operation |
|---|---|
| (1) | When the power source is on (ACC) and the driver pushes the power switch again, the power management control ECU recognizes the power switch signal and turns on the IG1 and IG2 relays. |
| Step | System Operation |
|---|---|
| (1) | When the power switch is pushed once with the following conditions satisfied, the power management control ECU recognizes the power switch signal and turns off the ACC, IG1 and IG2 relays.
|
| (2) | When the power source is changed from on (IG) to off, the power management control ECU will turn off the indicator light of the power switch. |
| (3) | When the certification ECU recognizes that the power source is off, it transmits the engine immobiliser set signal to the ID code box (immobiliser code ECU). |
| (4) | The ID code box (immobiliser code ECU) certifies that the certification ECU (smart key ECU assembly) signal is appropriate, transmits the engine immobiliser set signal to the power management control ECU, and sets the engine immobiliser. |
| (5) | If the driver door is opened, the certification ECU receives a signal from the main body ECU (multiplex network body ECU). After that, the certification ECU transmits the steering lock signal to the power management control ECU. |
| (6) | The power management control ECU receives the steering lock signal and supplies power to the steering lock ECU. |
| (7) | The steering lock ECU operates the lock motor until the steering lock is engaged if the ID code box (immobiliser code ECU) certifies that the certification ECU (smart key ECU assembly) is appropriate. |
Pattern C: Off → On (ACC) → On (IG) → On (ACC)
| Step | System Operation |
|---|---|
| (1) | The system operations for pattern C (off → on (ACC) → on (IG)) are the same as those in pattern B. |
| (2) | When the power switch is pushed once with the following conditions satisfied, the power management control ECU recognizes the power switch signal and turns off the IG1 and IG2 relays.
|
| (3) | Even after the power switch turned from on (IG) to on (ACC), the indicator light of the power switch will remain illuminated in amber. |

| Step | System Operation |
|---|---|
| (1) | When the power switch is pushed once with the following conditions satisfied, the power management control ECU recognizes the power switch signal and turns off the ACC, IG1 and IG2 relays.
|
| (2) | The rest of the system operation is same as (3) to (7) of the "on (IG) → off" in pattern B. |
Pattern E: READY → On (ACC)
This system operation is the same as for pattern C. However, the indicator light of the power switch will illuminate as follows:
When the power source is changed from READY to on (ACC), the power management control ECU continues to illuminate the amber indicator light of the power switch.
When the hybrid control system is turned off using the power switch (power source mode is changed to off), the power management control ECU turns off the indicator light of the power switch.
When a key battery is weak.
| Step | System Operation |
|---|---|
| (1) | To operate the entry and start system when the key battery is weak, depress the brake pedal and hold the key against the power switch as shown in the illustration. |
| (2) | The power management control ECU receives the stop light switch signal and transmits a key certification request signal to the certification ECU (smart key ECU assembly). |
| (3) | The certification ECU (smart key ECU assembly) does not receive an ID code response from the door control receiver, so it actuates the transponder key amplifier built into the power switch. |
| (4) | The transponder key amplifier outputs an engine immobiliser radio wave signal to the key. |
| (5) | The key receives the radio wave signal, and returns a radio wave signal response to the transponder key amplifier. |
| (6) | The transponder key amplifier combines the key ID codes with the radio wave signal response, and transmits it to the certification ECU (smart key ECU assembly). |
| (7) | The certification ECU (smart key ECU assembly) judges and verifies the ID code, and transmits a key certification OK signal to the power management control ECU. The buzzer in the combination meter assembly sounds once. |
| (8) | After the buzzer sounds, if the power switch is pushed within 10 seconds while the brake pedal is depressed, the hybrid control system will be started, the same as with normal smart key operation. |
| (9) | After the buzzer sounds, if the power switch is pushed within 10 seconds while the brake pedal is not depressed, the power source mode will change to on (ACC) or on (IG), the same as with normal smart key operation. |

Battery Saving
1. Vehicle Battery Saving Function
In the entry and start system, signals are emitted outside of the vehicle at a prescribed interval (250 ms) when the doors are locked. Therefore, the vehicle battery could be drained if the vehicle remains parked for a long time. For this reason, the controls listed below are used.
| Condition | Control |
|---|---|
| No response from key for more than 5 days | Signal transmission interval is extended from 250 ms to 750 ms. |
| No response from key for more than 14 days | Automatically deactivates the entry and start system. |
Reinstatement Conditions:
A wireless door lock control signal (lock, unlock, or trunk lid open) is input and the ID matches.
A user who has the key in their possession touches a lock sensor on an outside door handle.
A door is locked or unlocked using the mechanical key.
2. Key Battery and Vehicle Battery Saving Function
In the entry and start system, if the key is kept (stored) in the exterior actuation area of the doors, the system will maintain periodic communication with the key. Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle battery could be drained.
For this reason, if this state continues for longer than 10 minutes, the entry and start system will automatically deactivate.
Reinstatement Conditions:
A wireless door lock control signal (lock, unlock, or trunk lid open) is input and the ID matches.
A user who has the key in their possession touches a lock sensor on an outside door handle.
A door is locked or unlocked using the mechanical key.
Key Cancel
A key cancel function is provided to make it possible to disable the entry and start system. Key cancel can be operated when certain steps are performed with the vehicle in the following condition:
The power switch is off.
The driver door is closed.
The driver door is unlocked.
Tech Tips
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 within 30 seconds, and open again. (Driver door: open → close → open → close → open)
Unlock twice with the unlock button of the key within 30 seconds.
Repeat open → close once for the driver door within 30 seconds, 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 once.
To return to the original condition, perform the procedures again. When entry and start system operation has been restored, the wireless door lock buzzer sounds twice.
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 to and stored) in the EEPROM. For details of the recognition code registration procedure, refer to the Service Bulletin for the ENGINE IMMOBILISER SYSTEM (KEY REGISTRATION).
| Mode | Function |
|---|---|
| Rewrite | Clears all previously registered codes and registers only the newly received codes. This mode is used whenever a transmitter or the ID code box is replaced. |
| Add | 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 7, the oldest registered code is cleared first. |
| Confirm | Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist. |
| Prohibit | To clear all the registered codes and to prohibit the wireless door lock function. This mode is used when a key is lost. |
CONSTRUCTION
Key
The key 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 and glove box lock cylinder, but cannot be used to start the hybrid control system. When the mechanical key is used, the cap of the driver door lock cylinder must be removed.
The transmitter for the wireless door lock control has a lock button, unlock button, panic button, and power back door button.
The transceiver of the key receives the signals from the oscillators and returns the ID code to the door control receiver.
The transponder chip for the engine immobiliser function returns a signal to the power switch as a response to the radio wave received from the power switch.
| *1 | Mechanical Key | *2 | Lock Button |
| *3 | Unlock Button | *4 | Power Back Door Button (Models with power back door system and panic control) |
| *5 | Power Back Door Button (Models with power back door system and without panic control) | - | - |
Power Switch
The power switch consists of a momentary type switch, indicator light (amber and green color LEDs), illumination, antenna coil, and transponder key amplifier.
The driver can determine the present power source* and check whether the hybrid control system can start or not in accordance with the illumination state of the indicator light.
When the power management control ECU detects an abnormality with the entry and start system, it makes the amber indicator light flash. If the hybrid control system is stopped in this state, it might not be possible to restart it.
*: In this chapter, the expression "power source" has been used in some locations to allow precise explanations. The power source condition is also expressed using conventional expressions such as "power switch off", "power switch on (ACC)" and "power switch on (IG)".
| Power Source Condition | Indicator Light Condition | |
|---|---|---|
| Brake pedal not depressed | Brake pedal depressed with shift lever in P or N | |
| Off | OFF | ON (Green) |
| On (ACC), On (IG) | ON (Amber) | ON (Green) |
| READY | OFF | OFF |
| Steering Lock not Unlocked | Flashes (Green) for 15 seconds | Flashes (Green) for 15 seconds |
| Entry and Start System Malfunction | Flashes (Amber) for 15 seconds | Flashes (Amber) for 15 seconds |
Power Management Control ECU
Power management control ECU consists of the IG1 relay and IG2 relay actuation circuits, CPU, and hold circuit.
The hold circuit is installed to prevent the power supply to the relays from being cut off when an abnormality occurs in IG1 relay and/or IG2 relay actuation circuits while driving.
Tech Tips
The power management control ECU constantly stores the present power source state in its memory. Therefore, if the power to power management control ECU is interrupted due to the removal of the battery, the power management control ECU restores the power source after the battery is reconnected.
For this reason, if the battery is removed when the power source is in a mode other than off, the power will be restored to the vehicle at the same time the power is restored to power management control ECU (by reconnecting the battery).
Therefore, before removing the battery, be sure to turn the power source off.
DIAGNOSIS
Start Function
The power management control ECU and certification ECU (smart key ECU assembly) can detect malfunctions in the entry and start system when the power source is on (IG).
When the ECUs detect a malfunction, the amber indicator light of the power switch flashes to warn the driver. At the same time, the ECUs store a 5-digit Diagnostic Trouble Code (DTC) in their memories.
The indicator light warning continues for 15 seconds even after the power switch is turned to off.
The 5-digit DTCs can be read after connecting the intelligent tester to the DLC3.
The entry and start system may not operate successfully if a malfunction occurs.
