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 system while the vehicle is in motion.
If no signals are transmitted to the power management control ECU assembly due to malfunctions in the stop light switch assembly or transmission control ECU assembly, the hybrid 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 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 system must not be stopped by pushing the power switch while driving. Also, it should not be started without depressing the brake pedal or when a shift state other than park (P) has been selected.
Pattern A: Off → READY (Hybrid 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 assembly 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 and 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 |

Battery Saving
Battery saving preserves the vehicle and key batteries. It is activated when the vehicle remains parked for a long time and when the key is left inside the exterior actuation area.
| Condition | Control | Reinstatement Condition |
|---|---|---|
| When the vehicle remains parked for a long time. | Control 1:
|
When the power switch is turned on (IG), the control is canceled and the system is returned to normal. |
| Control 2:
|
|
|
| When the key is left within the exterior detection area. |
|
|
In addition to the above functions, the auto power off function helps to reduce drain on the vehicle auxiliary battery by turning the power source mode to off when approximately 60 minutes have elapsed since (a) the P position switch (transmission shift main switch) was pushed and the power source was turned to on (ACC), or (b) the hybrid system off with the park (P) selected, the power source on (IG) and the vehicle stationary.
Key Cancel
The following system functions can be deactivated by using the key cancel operating procedure.
Entry Lock
Entry Unlock
Prevention of Key Confinement
Warning
The system functions can be deactivated by using the following key cancel operating procedure when the power switch is off and the driver door is closed and unlocked.
| Key Cancel operating procedure |
When the cancel procedure is complete, the buzzer sounds twice. Meanwhile, when the procedure is performed again to resume the system, the 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 7 different codes can be registered. The codes are electronically registered (written to and stored) in the EEPROM. For details, refer to the Repair Manual.
| Mode | Function |
|---|---|
| Add | Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter. |
| Confirm | Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist. |
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, but cannot be used to start the hybrid system.
The transmitter for the wireless door lock control has a lock button and unlock button.
The transceiver in the key receives the signals from the oscillators and returns the ID code of the key 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.
| *A | Models with Panic Alarm | ||
| *1 | Lock Button | *2 | Unlock Button |
| *3 | Mechanical Key | *4 | Panic Button |
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 mode* and check whether or not the hybrid system can start 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 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 P selected | |
| Off | OFF | ON (Green) |
| On (ACC), On (IG) | ON (Amber) | ON (Green) |
| READY | OFF | OFF |
| Entry and Start System Malfunction | Blinks (Amber) for 15 seconds | Blinks (Amber) for 15 seconds |
Power Management Control ECU
The power management control ECU includes 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 mode in its memory. Therefore, if the power to the 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 the 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.
