Door Lock Function of Keyless Start SystemS7RS0BA501004
When the request switch (1) incorporated in the outside handle of the driver side door, front passenger side door or
rear end door is pushed, the keyless start control modul e (2) activates the center antenna (3) and luggage room
antenna (4) to send out the radio wave in the vehicle compartm ent to check if the remote controller (5) is in the vehicle
compartment or not. When the keyless start control module receives no signal from the remote controller (i.e., the
remote controller does not exist in the vehicle compartment) , it activates the antenna (6) of the door of which the
request switch has been pushed to send the request signal out of the compartment.
If the remote controller exists within the door lock operati on area, it receives the request signal sent from the above
said antenna, sends the ID code of the remote controller and the request signal to the keyless start control module and
at the same time, it makes the operatio n indicator lamp (7) of the remote controller light up. Lighting of the operation
indicator lamp indicates that the remote controller sent the ID code and the request signal.
The keyless start control module compares the ID code sent from the remote controller with the ID code registered in
the keyless start control module. If both ID codes match, the keyless start control module outputs the lock or unlock
request signal (depending on the door lock switch (8) stat e then) to BCM (9). When BCM receives such signal through
CAN communication from the keyless start control module, it activates the door lock actuator to lock or unlock doors.
When the keyless start control module receiv es a signal from the remote controller (i.e., the remote controller exists in
the vehicle compartment), the function of the keyless start system to prevent the remote controller from being closed in
the vehicle works and the keyless start control module sends a request signal to unlock doors to BCM. In this way,
doors are kept unlocked.
Also, when the driver or passenger has left the vehicl e with the remote controller left behind in the vehicle
compartment and locked doors by using the door lock knob or manual door lock switch, the function to prevent the
remote controller from being closed in the vehicle works to unlock doors.
Furthermore, when ID codes of the remote controller and keyless start control module do not match or the remote
controller exists outside of the operation area, doors are not locked or unlocked even if the request switch of the
outside handle is operated.

Operation Area of Remote ControllerS7RS0BA501005
Shown below are the operation areas of the remote controller for the keyless engine start function and door lock
function of the keyless start system.
However, even when the remote controller is within the operation area as shown above, there are cases where the
keyless start system doesn’t work under certain conditi ons as described below. And when the keyless engine start
function doesn’t work, the key indicator la mp in the combination meter may light up.
• Doors cannot be locked or unlocked using the doo r lock function of keyless start system when:
– The remote controller which has been registered in the keyless start control module and another un-registered one are both carried at the same time
– The remote controller is kept in some metallic co ntainer which disturb radio wave transmission/reception
– One of doors is open
– The ignition key is inserted in the ignition key cylinder
• The function of the keyless start system to prevent the remote controller from being closed in the vehicle
compartment doesn’t work when:
– The remote controller is in the door pocket or in the glove box
– The remote controller is kept in some metallic co ntainer which disturb radio wave transmission/reception
– The remote controller is placed close to outside of the vehicle compartment (such as on the instrument panel beside the front window shield glass or in a corner of the luggage room)
• The ignition knob switch cannot be turned usin g the keyless engine start function fails to turn:
– The remote controller which has been registered in the keyless start control module and another un-registered one are both carried at the same time
– The remote controller is kept in some metallic cont ainer which disturbs radio wave transmission/reception
– The ignition knob switch has been pushed for 5 seconds or longer
– The remote controller is placed close to outside of the vehicle compartment (such as on the instrument panel beside the front window shield glass or in a corner of the luggage room)
