DOOR ENTRY FUNCTION


DESCRIPTION OF CONSTRUCTION AND OPERATION






note *: In the communication for certification of the keyless operation key, KOS-ECU judges if the keyless operation key ID (specified to keyless operation key) contained in the response data from the keyless operation key coincides with the ID that has been stored in ECU by registration operation. The keyless operation key sends the response to KOS-ECU only when the KOS ID (specific to KOS-ECU) contained in the received data coincided with the stored ID. In the beginning of the communication for certification, KOS-ECU creates an encrypted code calculation factor in random number, and sends it to the keyless operation key together with the transmit data. The keyless operation key calculates the code by using the received factor, and sends the result to KOS-ECU together with the response data. KOS-ECU determines that the communication is established only when the code calculation results of both parties coincided.

UNLOCKING OPERATION OF DOOR ENTRY FUNCTION



CONTROL OF UNLOCKING OPERATION




1.
note *: The interfering radio wave is transmitted to disable the door unlock operation by a person without the keyless operation key while a user with the keyless operation key is performing the door unlock operation from the opposite side of the vehicle.
2.
3.

  • When the keyless operation key receives the exterior data only, KOS-ECU transmits the unlock request (request to unlock the applicable position) to ETACS-ECU.
  • When KOS-ECU received no response that enables the unlocking after the specified time period has passed, it performs the retry cycle once (When no response after the retry, KOS-ECU terminates the unlocking operation).

UNLOCKING OPERATION INHIBITION TIME



UNLOCKING OPERATION INHIBITION CONDITIONS




  • The emergency key is in the ignition switch.
  • The push switch in the steering lock is ON.
  • The IG knob is in other than LOCK (OFF) position.
  • During the unlocking operation inhibition time.
  • One or more of the doors or tailgate is open (door switch is ON) (including door ajar).
  • Inside handles of driver’s side and front passenger’s side are unlocked.
  • The door entry function is prohibited by the customisation function (refer to ).

LOCKING OPERATION OF DOOR ENTRY FUNCTION



CONTROL OF LOCKING OPERATION




1.
2.
3.

  • When KOS-ECU receives the response from the keyless operation keys that received the interior data, KOS-ECU cancels the locking operation.
4.
5.

  • When KOS-ECU receives the response from the keyless operation keys that received the interior data, KOS-ECU cancels the locking operation.
  • When all the responding keyless operation keys receive the exterior data only, KOS-ECU transmits the lock request to ETACS-ECU.
  • If there is no response from the keyless operation keys, perform the step 6 once.
6.
7.

  • When the responded keyless operation keys after the retry receives the exterior data only, KOS-ECU transmits the lock request (request to lock the actuated position) to ETACS-ECU.

LOCKING OPERATION INHIBITION CONDITIONS




  • One or more of the doors or tailgate is open/ajar (door switch is ON). (including door ajar)
  • The emergency key is in the ignition switch.
  • The push switch in the steering lock is ON.
  • The IG knob is in other than LOCK (OFF) position.
  • The door entry function is prohibited by the customisation function (refer to ).
