NOTE
When performing the this inspection, make
sure to have any of the door once opened /
closed after the ignition key has been
removed from the ignition key cylinder.
1) Confirm that power door lock system operates
normally, refer to “Power Door Lock System
Operation Inspection (If Equipped)”.

Replacement of Transmitter Battery (Other than
Keyless Start Model)
S6RW0D9606014
NOTE
For keyless start model, perform
“Replacement of Remote Controller Battery
in Section 10E” instead of “Replacement of
Transmitter Battery (Other than Keyless Start
Model)”.
If transmitter becomes unreliable, replace transmitter
battery as follows.
1) Remove screw (1) and transmitter cover (2).
2) Remove transmitter (3) from transmitter holder (4).
CAUTION!
Use care not to allow grease or dirt to be
attached on the printed circuit board and the
battery.
3) With tip of flat blade screwdriver put in slot of
transmitter, pry it open.
4) Replace the battery (lithium disc-type CR 1620 or
equivalent battery) so its (+) terminal faces “+” mark
on transmitter.
5) Fit together transmitter (3) and install it into
transmitter holder (4).
6) Install transmitter cover (2) and screw (1).7) Make sure that door locks can be operated with
transmitter.
NOTE
• To prevent theft, be sure to break the
transmitter before discarding it.
• Dispose of the used battery properly
according to applicable rules or
regulations. Do not dispose of lithium
batteries with ordinary household trash.

• Three transmitter codes can be registered.
• When a new transmitter code is registered,
the oldest one will be cleared.
• As for vehicle equipped with keyless start
system, perform “Registration Procedure
for Remote Controller ID Code in Section
10E” instead of “Programming Transmitter
Code for Keyless Entry System (Other than
Keyless Start Model)”.
If transmitter or BCM (included in junction block
assembly) is replaced with a new one or additional
transmitter(s) is necessary, program transmitter code(s).
1) Confirm that all doors are closed and ignition key is
out of ignition key cylinder.
2) Open driver side door.

Keyless Engine Start FunctionS6RW0DA501003
When the ignition knob switch (2) installed to the steering lock unit (1) is pushed, the keyless start control module (3)
activates the center antenna (4) to send out the request signal in the vehicle compartment. When the remote controller
(5) receives the request signal from the center antenna, it transmits the ID code to the keyless start control module.
The keyless start control module compares the ID code sent by the remote controller with the ID code registered in the
keyless start control module. When these ID codes match, the keyless start control module makes the key indicator
light (7) in the combination meter (6) light in blue and unlocks the steering lock unit to enable the ignition knob switch
to turn. When the ignition knob switch is turned to ON position in this state, ID codes of ECM and keyless start control
module are compared through CAN communication (immobilizer function). When they match, turning the ignition knob
switch to start position will start the engine.
NOTE
When ignition knob switch is at ACC or ON position (engine not running) and any door has been kept
open for a certain time, it may happen that engine fails to start. In such a case, turn ignition knob
switch to OFF position once and then try to start engine again.
When the ID code from the remote controller and the ID code registered in the keyless start control module do not
match or when the remote controller is outside the operation area of the remote controller and the ignition knob switch
is pushed, the steering lock unit cannot be unlocked and so the ignition knob switch cannot be turned. Then, the
keyless start control module makes the key indicator light in the combination meter light in red to warn the driver that it
is not possible to turn the ignition knob switch.
In case of vehicle equipped with immobilizer control system, when the ID code of ECM and that of the keyless start
control module do not match, the engine cannot be started even if the ignition knob switch is turned to the start
position. Then ECM makes the immobilizer indicator light in the combination meter flash to warn the driver that it is not
possible to start the engine.

Door Lock Function of Keyless Start SystemS6RW0DA501004
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 module (2) activates the center antenna (3) and luggage room
antenna (4) to send out the radio wave in the vehicle compartment 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 operation 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 operation indicator light (7) of the remote controller light up. Lighting of the operation
indicator light 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) state 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 receives 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 vehicle 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 ControllerS6RW0DA501005
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 conditions as described below. And when the keyless engine start
function doesn’t work, the key indicator light in the combination meter may light up.
• Doors cannot be locked or unlocked using the door 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 container 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 container 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, on the rear parcel shelf or in a corner of the luggage room)
