42 -BODY > 42B-KEYLESS OPERATION SYSTEM (KOS) > SYSTEM OPERATION > DOOR ENTRY FUNCTION
DESCRIPTION OF CONSTRUCTION AND OPERATION
When a driver carrying a keyless operation key presses the lock/unlock switch in the front door out side handle (driver's side, passenger's side) or the lock/open switch of tailgate lock release handle, the KOS&OSS-ECU communicates with the keyless operation key to authorise the keyless operation key. When the KOS&OSS-ECU authorises the registered keyless operation key within 70 cm in radius out of the vehicle, it requests the ETACS-ECU to lock/unlock the doors. Note that the key may not be authorised even if it is within this range, when it is positioned too high or too low.
LOCKING OPERATION OF DOOR ENTRY FUNCTION
When the lock/unlock switch in the front door outside handle (driver's side, passenger's side) or the lock/open switch of tailgate lock release handle is turned ON, the KOS&OSS-ECU communicates with the keyless operation key to authorise it. When the KOS&OSS-ECU can authorise the registered keyless operation key only outside the vehicle only, it requests the ETACS-ECU to lock all the doors (including tailgate). At this time, the outside door mirrors are also folded.
| note | If any keyless operation key is located inside the vehicle, the KOS&OSS-ECU does not request the ETACS-ECU to lock all the doors. |
LOCKING OPERATION INHIBITION CONDITIONS
In the following cases, the door locking operation is inhibited.
- Any door is open (door switch is ON). (including door ajar)
- Either of the keyless operation antenna is being detected to be open, or it is actually open.
- The wiring of keyless operation antenna is contacting against the earth line.
- The engine switch is other than "OFF".
- The lock and unlock signals are input at the same time.
- During the unlocking operation inhibition time (When the tailgate is operated).
- The door entry function is prohibited by the customisation function.
UNLOCKING OPERATION OF DOOR ENTRY FUNCTION
When the lock/unlock switch in the front door outside handle (driver's side, passenger's side) or the tailgate lock/open switch of tailgate lock release handle is turned ON, the KOS&OSS-ECU communicates with the keyless operation key to authorise it. When the KOS&OSS-ECU can authorise the registered keyless operation key only outside the vehicle, it requests the ETACS-ECU to unlock all the doors (if any registered keyless operation key is authorised outside the vehicle, the KOS&OSS-ECU requests the ETACS-ECU to unlock all the doors even when other registered keyless operation keys are located inside the vehicle). At this time, the outside door mirrors are also unfolded.
UNLOCKING OPERATION INHIBITION TIME (WHEN THE TAILGATE IS OPERATED)
Considering that the customer operates the open switch of tailgate lock release handle to make sure the doors are locked, the unlocking operation is prohibited for 3 seconds after the locking operation is performed by the lock switch of tailgate lock release handle. Using the customisation function, the unlock prohibition time can be changed.
UNLOCKING OPERATION INHIBITION CONDITIONS
In the following cases, the unlocking operation is prohibited.
- When either door opens (a door switch ON) and a door is not closed properly, and while the open switch of tailgate lock release handle is not operated.
- Inside lock knob position of driver's side or passenger’s side is set to unlock.
- The engine switch is other than "OFF".
- The keyless operation antenna is being detected to be open, or it is open.
- The wiring of keyless operation antenna is contacting against the earth line.
- The door entry function is prohibited by the customisation function.
ANSWERBACK FUNCTIONS
When KOS&OSS-ECU sends a signal to ETACS-ECU, ETACS-ECU outputs the lock/unlock signal and activates the hazard warning lamp to notify the driver the doors are locked/unlocked.
| Lock signal received | Unlock signal received |
| ETACS-ECU | Lock signal output | Unlock signal output |
| Hazard warning lamp | Flashes once (initial setting) | Flashes twice (initial setting) |
KOS TIMER LOCK FUNCTION
When none of the doors are opened within 30 seconds after the doors are unlocked by KOS, ETACS-ECU automatically outputs the door lock signal to lock the doors. This function prevents the doors from being unlocked accidentally. Using a customisation function, the timer lock period can be changed. (Refer to
