A keyless entry system has been adopted in which locking/locking is performed by operation of the remote transmitter button, even from a location away front the vehicle.
The start stop unit performs keyless entry system fail-safe. (See START STOP UNIT.)
When the following operation is performed, the start stop unit verifies the remote transmitter ID data.
Locking/unlocking using a remote transmitter
Trunk lid opening using remote transmitter
The keyless entry system has the following functions in the event that the user operates the system incorrectly or to prevent the user from leaving the vehicle without locking.
Auto re-lock function: After unlocking, if any door or the trunk lid is not opened and a period of time according to the personalization setting has elapsed, all doors are automatically locked.
Remote transmitter pause function: All the functions of the remote transmitter other than the remote transmitter used for the door lock are paused.
Alert function: If the system is operated incorrectly which results in a possible problem occurring, the system warns the user by using the indicator light, warning light, LCD display, and buzzer in the instrument cluster.
This function notifies the user that the battery voltage of the remote transmitter is low.
NOTE:
If the lock button of the remote transmitter is operated when all of the following conditions are met, all the doors are locked.
Ignition is switched off (LOCK)
All doors are closed
If the unlock button of the remote transmitter is operated when all of the following conditions are met, all the doors are unlocked.
Ignition is switched off (LOCK)
1. When the lock or unlock button of the remote transmitter is pressed, the remote transmitter sends ID data.
2. The keyless receiver receives ID data and transmits the data to the start stop unit.
3. The start stop unit verifies the ID data, and if the ID data matches, it sends a lock/unlock request signal to the rear body control module (RBCM).
4. The rear body control module (RBCM) operates the front/rear door lock actuator motor to lock/unlock the front/rear doors.
5. At the same time as the door lock/unlock operation, it sends a hazard light flash request signal to the instrument cluster as a CAN signal.
6. The instrument cluster sends the hazard light flash request signal to the front body control module (FBCM) as a CAN signal.
7. The front body control module (FBCM) controls the hazard lights to flash for the following number of times to signal that the lock/unlock operation is completed.
Lock: Flashed once
Unlock: Flashed twice
NOTE:
The trunk lid opens when the trunk lid open button on the remote transmitter is pressed with the ignition switched OFF (LOCK).
1. When the trunk lid open button is pressed for approx. 0.5 s, the remote transmitter sends ID data to the keyless receiver.
2. The keyless receiver receives ID data and transmits the data to the start stop unit.
3. The start stop unit verifies the ID data, and if the ID data matches, it sends a trunk lid release signal to the rear body control module (RBCM).
4. When the rear body control module (RBCM) receives the trunk lid release signal, it operates the trunk lid release actuator motor to release the trunk lid.
After the start stop unit sends an unlock request signal to the rear body control module (RBCM), if any of the following operations is not performed in 60 s*1, it sends a lock request signal to the rear body control module (RBCM) to lock the front/rear doors.
A door or the trunk lid is opened
A lock/unlock operation is performed using the driver's side front door key cylinder.
A lock/unlock operation is performed using the driver's side front door lock knob.
A lock/unlock operation is performed using the remote transmitter.
The ignition is switched to ACC or ON (engine off).
When door locking is performed
If a door is locked by the remote transmitter operation when all the following conditions are met, all the functions of the remote transmitter other than the remote transmitter used for the door lock operation are paused.
All doors and trunk lid are closed
Ignition is switched off (LOCK)
Remote transmitter pause cancel operation
The functions of the paused remote transmitter are restored when the following conditions are met:
A remote transmitter with which the engine can be started is brought inside the vehicle.
The lock/unlock button on the paused remote transmitter is pressed.
Under the following conditions, the start stop unit sends a warning request signal to the instrument cluster via CAN communication to illuminate the push button start indicator light (amber).
When the instrument cluster receives the security warning request signal, it displays the warning indicator in the LCD display (instrument cluster type A) or it flashes the KEY warning light (instrument cluster type B).
| Condition | Instrument cluster | Push button start |
||
| Keyless warning alarm | KEY warning light (red) | LCD display | Indicator light (amber) |
|
| Keyless entry system malfunction | ― | On |
| Flash |
| Driver's door is opened with ignition in ACC | Pattern A*1×Continuous | ― |
| ― |
| Remote transmitter cannot be detected inside vehicle when all doors are closed with ignition not switched off (LOCK) | Pattern B*1 | Flash |
| ― |
When the ignition is switched from ON (engine off or on) to off (LOCK) under the condition indicated in the table, the start stop unit sends a battery voltage low indication request signal to the instrument cluster as a CAN signal.
When the instrument cluster receives the battery voltage depletion display request signal, it performs the remote transmitter battery voltage low indication in the LCD display (instrument cluster type A) or it flashes the KEY indicator light (instrument cluster type B).
| Condition | Instrument cluster |
|
| KEY indicator light (green) | LCD display |
|
| Start stop unit receives code for low remote transmitter battery voltage | Flash (for approx. 30 s after ignition switched off) |
