Main components and functions
Parts name
Functional description
KOS-ECU
Controls KOS by using the following inputs/outputs and communications.

  • Input of front door lock/unlock switch, input of tailgate lock release handle, and input of tailgate lock switch
  • Communications with ETACS-ECU, OSS-ECU and combination meter via CAN
  • Wireless communication of keyless operation key via the interior and exterior transmitter antennas as well as via the key slot integrated antenna
  • Output to the outer buzzer
  • Output of actuator driving permission signal to electric steering lock
Electric steering lock (incorporates electric steering lock unit)
The steering lock mechanism incorporates a mechanism that can electrically unlock the lock. When the lock is unlocked electrically, the steering lock is unlocked approximately for 30 seconds by the certification communication with OSS-ECU via LIN communication, the power supply permission signal obtained via wire communication, and the actuator driving permission signal received via wire communication from KOS-ECU.
Keyless operation key (incorporates emergency key)

  • The keyless operation key receives signals sent from each interior/exterior transmitter antenna, certifies the key ID code, calculates the encrypted code, and sends the reply data signal to KOS-ECU. If the integrated battery is discharged, the keyless operation key receives signals sent from the key slot when it is inserted in the key slot. Then, it certifies the key ID code, calculates the encrypted code, and sends the reply data signal to KOS-ECU via the key slot. Also, when the lock/unlock switch on the keyless operation key is pressed, the corresponding signal is sent to KOS-ECU.
  • If two or more keyless operation keys registered in KOS-ECU respond at the same time, their signals would interfere. To avoid this interference, each signal from KOS-ECU is given the priority* data, and the keyless operation keys respond in accordance with this priority.

Lock/Unlock
Driver’s side
Locks/unlocks all the doors and tailgate when the driver carrying the keyless operation key presses the lock/unlock switch on the front door outside handle.
Passenger’s side
Tailgate lock release handle
Locks all the doors and the tailgate when a driver carrying the keyless operation key presses the lock switch on the front door outside handle or on the tailgate lock release handle.
Tailgate lock switch
Locks all the doors and tailgate when the driver carrying the keyless operation key presses the lock switch on the tailgate lock release handle.
Exterior transmitter antenna assembly

Converts the data output from KOS-ECU via wire into a signal, and sends it to the keyless operation key (The transmission/reception area is the same as the conventional OUTLANDER.).
Passenger’s side
Tailgate
Interior transmitter antenna assembly
Front
Converts the data output from KOS-ECU via wire into a signal, and sends it to the keyless operation key (For more information on the transmission/reception area, refer to the one-touch start system valid area).
Rear
Outer buzzer
The outer buzzer sounds when:

  • The doors are locked or unlocked by the door entry function.
  • The keyless operation key is carried out of the vehicle when the power supply mode is other than OFF, and the door is closed.
  • The lock/unlock switch on the front door outside handle is pressed when the power supply mode is other than OFF.
  • The lock/unlock switch on the front door outside handle is pressed when the keyless operation key is still located inside the car.
  • The lock/unlock switch on the front door outside handle is pressed when the door is ajar.
  • With the driver’s door kept open, the keyless operation key is not removed from the key slot located in the glove box.
Key slot
Converts the data output from KOS-ECU via wire into a signal, sends it to the keyless operation key, and then sends the reply data signal from keyless operation key to KOS-ECU.
OSS-ECU
Controls OSS by using the following inputs/outputs and communications.

  • Input from the engine switch
  • Input from stop lamp switch <CVT vehicle>
  • Input from clutch switch <M/T vehicle>
  • Input from P range detection switch <CVT vehicle>
  • Input of monitoring signal for actuator driving permission of electric steering lock via wire communication with KOS-ECU
  • Output of KOS back-up power supply via wire communication with KOS-ECU
  • Power supply output to electric steering lock unit
  • CAN communication with KOS-ECU, ETACS-ECU, engine ECU, and combination meter
  • LIN communication with electric steering lock
Engine switch

  • Output of engine switch ON/OFF signal to OSS-ECU
  • Input of LED signal from OSS-ECU

Combination meter (keyless operation alarm display)
Communicates with KOS-ECU and OSS-ECU via CAN. Receives the warning request or warning information from KOS-ECU and OSS-ECU, and displays the warning.
ETACS-ECU

  • Communicates with KOS-ECU via CAN. By the door lock/unlock request or tailgate lock/unlock request from KOS-ECU, ETACS-ECU outputs the lock/unlock signal. When the door lock/unlock signal is output, the ETACS-ECU flashes or illuminates the turn-signal lamps and the room lamp to notify the driver that the doors are locked/unlocked. Furthermore, by the multi-mode function of keyless entry, the folding/unfolding of door mirrors is performed depending on the pattern of door lock/unlock request from KOS-ECU.
  • Communicates with OSS-ECU via CAN, and outputs the door switch ON/OFF signal.
  • Receives the ACC output signal or IG1 output signal sent from OSS-ECU via wire communication, and drives the ACC relay or supplies electrical current to the IG1 relay to drive the IG1 relay.
  • Using the welcome light function, the headlamps and tail lamps are illuminated by the door unlock request from KOS-ECU.

Engine-ECU
Communicates with OSS-ECU through ETACS-ECU via CAN. Permits/inhibits the engine starting and controls the engine operation.
note *: When registering the keyless operation keys, KOS-ECU numbers each key (1 to 4) in the order they are registered (initial priority). This priority is renewed each time the doors are locked/unlocked and the engine switch is pressed. For example, when only keys 1 and 3 have responded to the signal sent from KOS-ECU, the new priority of the keys would be 1-3-2-4. When keys 3 and 4 have responded, then the priority of the keys becomes 3-4-1-2.

System configuration





DOOR ENTRY FUNCTION



LOCKING OPERATION OF DOOR ENTRY FUNCTION




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 slot, the keyless operation key is not certified to be located inside the vehicle.

CONTROL OF LOCKING OPERATION




1.
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 tailgate lock release handle, KOS-ECU judges the lock prohibition condition. When the lock prohibition condition is met, the locking operation is terminated.
2.
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.
4.

  • 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.
6.

  • 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.
8.

  • 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




  • Any door or the tailgate is open (door switch is ON). (including door ajar)
  • Either of the exterior/interior transmitter antenna assembly is being detected to be open, or it is actually open.
  • The wiring of exterior/interior transmitter antenna assembly is contacting against the power supply line.
  • The ignition is other than OFF.

UNLOCKING OPERATION OF DOOR ENTRY FUNCTION



note When the driver’s door limited unlocking function is set to active using the customisation 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 tailgate).

CONTROL OF UNLOCKING OPERATION




1.
note When KOS-ECU detects the lock/unlock switch ON signal of door outside handle (driver’s side, front passenger’s side) or the tailgate 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.
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.
4.

  • 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.

ONE-TOUCH START SYSTEM CONFIGURATION





ONE-TOUCH START SYSTEM VALID AREA





note

If the keyless operation key battery is discharged, the one-touch start system (power supply changeover, engine start/stop) becomes available when the keyless operation key is inserted into the key slot located in the glove box. When inserting the keyless operation key to the key slot, easy locking of the key can be performed by inserting the key from the emergency key side.

Power supply changeover control (Operation description)




Flow of power supply changeover control
<1>
Under the power OFF status, operate the engine switch without depressing the brake pedal <CVT vehicle> or the clutch pedal <M/T vehicle>.
<2>
By the operation of engine switch, OSS-ECU sends KOS-ECU the certification request via CAN, and at the same time, supplies the electric steering lock unit power to the electric steering lock.
<3>
In accordance with the certification request from OSS-ECU, KOS-ECU performs the certification communication with the keyless operation key.
<4>
KOS-ECU sends the key certification result to OSS-ECU via CAN. OSS-ECU compares its certification result with the KOS-ECU certification result, and goes to <5> when the results agree with each other.
<5>
OSS-ECU performs the certification communication with the electric steering lock via LIN (local LIN). The electric steering lock compares the certification result with that of OSS-ECU, and unlocks the steering lock when the results agree with each other.
<6>
After the certification communication with the electric steering lock, OSS-ECU sends the ACC output to ETACS-ECU. Then, ETACS-ECU drives the internal ACC relay to turn the power to ACC.
<7>
With the power supply set to ACC, when the engine switch is operated again without depressing the brake pedal <CVT vehicle> or clutch pedal <M/T vehicle>, OSS-ECU sends the IG1 output. Then, the current is supplied to the IG1 relay in ETACS-ECU, thus driving the IG1 relay and turning the power ON. (At this time, OSS-ECU also communicates with engine-ECU to certify the engine start.)
<8>
With the power supply set to ON, when the engine switch is operated again without depressing the brake pedal <CVT vehicle> or clutch pedal <M/T vehicle>, the power of the CVT vehicle is turned OFF when the selector lever is in the P position, or the power is turned to ACC when in other than the P position. In the case with the M/T vehicle, the power is turned OFF. When the vehicle speed information, which is received via CAN, cannot be received or when the vehicle speed is 3 km/h or more, any standard engine switch operations will not be accepted. However, the power can be turned to ACC by the emergency stop operation*.
note *: The emergency stop operation refers to the operation to press and hold the engine switch for 3 seconds or longer, or to repeatedly press the engine switch 3 times or more within 1 second. After the emergency stop operation, OSS-ECU will not accept the engine switch operation for 2 seconds.

At the same time with the transmission of certification request to engine-ECU via CAN, OSS-ECU also sends the starter output to engine-ECU.
<2 (Diesel vehicle)>
At the same time with the transmission of certification request to engine-ECU via CAN, OSS-ECU also checks the glow status signal. When the glow status ON signal is received, OSS-ECU sends the starter output to engine-ECU. In the case of vehicles with AS&G, the starter output is sent to both engine-ECU and AS&G-ECU.
<3 (Vehicles without AS&G)>
Engine-ECU supplies current to the starter relay to perform cranking. Also, engine-ECU compares its own certification result with the OSS-ECU certification result, and starts the engine when the results agree with each other. (If the certification results do not agree with each other, engine-ECU stops the supplying of current to the starter relay and injector. Also, OSS-ECU stops the starter output.)
<3 (Vehicles with AS&G)>
AS&G-ECU supplies current to the starter relay to perform cranking. Also, engine-ECU compares its own certification result with the OSS-ECU certification result, and starts the engine when the results agree with each other. (If the certification results do not agree with each other, AS&G-ECU stops the supplying of current to the starter relay, and engine-ECU stops the supplying of current to the injector. Also, OSS-ECU stops the starter output.)
