Door Entry Function
GENERAL INFORMATION
DOOR ENTRY FUNCTION
LOCKING OPERATION OF DOOR ENTRY FUNCTION
The keyless operation key certification communication is performed when the lock/unlock switch of door outside handle (driver's side, front passenger's side) or the lock switch of liftgate lock release handle is turned ON. When KOS-ECU can certify the registered keyless operation key outside the vehicle only, it requests ETACS-ECU to unlock all the doors
(including liftgate).
NOTE:
- When a keyless operation key is located inside the vehicle, KOS-ECU does not output a request for locking all the doors.
- When a keyless operation key with discharged battery is inserted in the keyless operation key box, the keyless operation key is not certified to be located inside the vehicle.
CONTROL OF LOCKING OPERATION
1. KOS-ECU detects the lock/unlock switch ON signal of door outside handle (driver's side, front passenger's side) or the lock switch ON signal of liftgate lock release handle.
NOTE:
When KOS-ECU detects the lock/unlock switch ON signal of door outside handle
(driver's side, front passenger's side) or the lock switch ON signal of liftgate lock release handle, KOS-ECU judges the lock prohibition condition. When the lock prohibition condition is met, the locking operation is terminated.
2. KOS-ECU transmits the exterior data from the outside transmission antenna assembly on the operation side. At the same time, KOS-ECU transmits the interfering radio wave (reversal code) from the outside transmission antenna assembly on the other side. (The interfering radio wave will be transmitted from the front passenger-side antenna assembly when the driver-side door outside handle is operated, and vice versa. It will not be transmitted when the liftgate lock release handle is operated.)
NOTE:
*: The interfering radio wave is transmitted to disable the door locking/unlocking operation performed by a person without the keyless operation key while a user with the keyless operation key is operating from the opposite side of the vehicle.
3. After the exterior data are transmitted from the outside transmission antenna assembly, the interior data are transmitted from the inside transmission antenna assembly (front, rear).
4. After the specified time (varies with the number of keyless operation keys registered in KOS-ECU) has elapsed, a confirmation is made that there is no keyless operation key located inside the vehicle.
- When KOS-ECU receives the response from the keyless operation key that received the interior data, KOS-ECU terminates the process without performing the locking operation.
5. KOS-ECU transmits the interior data from the inside transmission antenna assembly
(front, rear).
6. After the specified time (varies with the number of keyless operation keys registered in KOS-ECU) has elapsed, a confirmation is made if the lock conditions are met.
- When KOS-ECU receives the response from the keyless operation key that received the interior data, KOS-ECU terminates the process without performing the locking operation.
- When all the responses from the registered keyless operation key are the exterior data only, KOS-ECU transmits the lock request to ETACS-ECU. Also, KOS-ECU transmits the keyless operation key number to ETACS-ECU.
NOTE:
When multiple keyless operation keys responded, KOS-ECU transmits ETACS-ECU the key number of keyless operation key that responded first. As for the transmission sequence to ETACS-ECU, the keyless operation key number is transmitted first, and then the lock request is output.
- If there is no response from the keyless operation key, Step 6 is performed once.
7. KOS-ECU transmits the exterior data from the outside transmission antenna assembly on the operation side. At the same time, KOS-ECU transmits the interfering radio wave* (reversal code) from the outside transmission antenna assembly on the other side. (The interfering radio wave will be transmitted from the front passenger's side when the driver's side door outside handle is operated, and vice versa. Also, it will be transmitted when the liftgate lock release handle is operated.)
8. If the specified time (varies with the number of keyless operation keys registered in KOS-ECU) has not elapsed, a confirmation is made if the lock conditions are met.
- After retry, when the responses from the registered keyless operation key are the exterior data only, KOS-ECU transmits the lock request (request to lock the applicable position) to ETACS-ECU. Also, KOS-ECU transmits the keyless operation key number to ETACS-ECU.
NOTE:
When multiple keyless operation keys responded, KOS-ECU transmits ETACS-ECU the key number of keyless operation key that responded first. As for the transmission sequence to ETACS-ECU, the keyless operation key number is transmitted first, and then the lock request is output.
- When the locking operation is performed on the driver's side, the priority order of keyless operation key is updated.
LOCKING OPERATION INHIBITION CONDITIONS
In the following cases, the door locking operation is inhibited.
- Any door or the liftgate is open (door switch is ON). (including door ajar)
- Either of the outside/inside transmission antenna assembly is being detected to be open, or it is actually open.
- The wiring of outside/inside transmission antenna assembly is contacting against the power supply line.
- The engine switch is other than OFF.
- The lock and unlock signals are input at the same time. (When the liftgate is operated)
- The door entry function is prohibited by the customization function.
UNLOCKING OPERATION OF DOOR ENTRY FUNCTION
The keyless operation key and KOS-ECU communicate to certify the keyless operation key when the lock/unlock switch of door outside handle (driver's side, front passenger's side) or the liftgate lock release handle (open switch) is turned ON. When KOS-ECU can certify the registered keyless operation key outside the vehicle, it requests ETACS-ECU to unlock all the doors (when a registered keyless operation key is certified outside the vehicle, KOS-ECU requests ETACS-ECU to unlock even when other registered keyless operation keys are located inside the vehicle).
NOTE:
When the driver's door limited unlocking function is set to active using the customization function, the operation can be performed using the lock/unlock switch of door outside handle (driver's side). Within 2 seconds after the driver's door is unlocked by pressing the lock/unlock switch of door outside handle (driver's side) once, pressing the lock/unlock switch of door outside handle (driver's side) unlocks all the doors (including liftgate).
CONTROL OF UNLOCKING OPERATION
1. KOS-ECU detects the lock/unlock switch ON signal of door outside handle (driver's side, front passenger's side) or the liftgate lock release handle (open switch) ON signal.
NOTE:
When KOS-ECU detects the lock/unlock switch ON signal of door outside handle
(driver's side, front passenger's side) or the liftgate lock release handle
(open switch) ON signal, KOS-ECU judges the unlock prohibition condition. When the unlock prohibition condition is met, the unlocking operation is terminated.
2. When KOS-ECU detects the lock/unlock switch ON signal of door outside handle
(driver's side, front passenger's side) or the liftgate lock release handle
(open switch) ON signal, KOS-ECU transmits the exterior data from the outside transmission antenna assembly on the operation side. At the same time, KOS-ECU transmits the interfering radio wave* (reversal code) from the outside transmission antenna assembly on the other side. (The interfering radio wave will be transmitted from the front passenger-side antenna assembly when the driver-side door outside handle is operated, and vice versa. It will not be transmitted when the liftgate lock release handle is operated.)
NOTE:
*: The interfering radio wave is transmitted to disable the door locking/unlocking operation performed by a person without the keyless operation key while a user with the keyless operation key is operating from the opposite side of the vehicle.
3. After the exterior data are transmitted from the outside transmission antenna assembly, the interior data are transmitted from the inside transmission antenna assembly (front, rear).
4. For the specified time (varies with the number of keyless operation keys registered in KOS-ECU), the response from the keyless operation key meeting the unlock condition is monitored.
- When the registered keyless operation key receives the exterior data only, KOS-ECU transmits the unlock request (request to unlock the applicable position) to ETACS-ECU.
- Even after the specified time has elapsed, if KOS-ECU receives no response that satisfies the unlock, it performs a retry once. (When no response after the retry, KOS-ECU terminates the unlocking operation.)
- When the unlocking operation is performed on the driver's side, the priority order of keyless operation key is updated.
UNLOCKING OPERATION INHIBITION TIME (WHEN THE LIFTGATE IS OPERATED)
Considering that the customer operates the lock switch of liftgate 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 liftgate lock release handle. Using the customization function, the unlock prohibition time can be changed.
UNLOCKING OPERATION INHIBITION CONDITIONS
In the following cases, the unlocking operation is prohibited.
- Any door or the liftgate is open (door switch is ON). (including door ajar)
- Inside lock knob position of driver's side and front passenger's side is set to Unlock.
- The engine switch is other than OFF.
- The lock and unlock signals are input at the same time. (When the liftgate is operated)
- The outside/inside transmission antenna assembly is being detected to be open, or it is open.
- The wiring of outside/inside transmission antenna assembly is contacting against the power supply line.
- During the unlocking operation inhibition time (When the liftgate is operated)
- The door entry function is prohibited by the customization function.
