Precautions for Installing Mobile
Communication Equipment
S6RW0D0000005
When installing mobile communication equipment such
as CB (Citizens-Band)-radio or cellular-telephone, be
sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic
control system.
• Keep the antenna as far away as possible from the
vehicle’s electronic control unit.
• Keep the antenna feeder more than 20 cm (7.9 in.)
away from electronic control unit and its wire
harnesses.
• Do not run the antenna feeder parallel with other wire
harnesses.
• Confirm that the antenna and feeder are correctly
adjusted.
Precaution for CAN Communication SystemS6RW0D0000006
• The loose (1) in the wire harnesses twist of the CAN
lines except around the connector (3) should be within
100 mm (3.9 in.). Refer to the wiring diagram for the
CAN lines discrimination. Excessively-loosed lines
may be influenced by the electric noise.
• Do not connect terminals of the CAN line using a
bypass wire (1). Otherwise, the CAN line may be
influenced by the electric noise.
Precautions for Electrical Circuit ServiceS6RW0D0000007
• When replacing a fuse, make sure to use a fuse of the
specified capacity. Use of a fuse with a larger capacity
will cause a damage to the electrical parts and a fire.
• When disconnecting and connecting coupler, make
sure to turn ignition switch OFF, or electronic parts
may get damaged.
• When disconnecting connectors, never pull the wiring
harness. Unlock the connector lock first and then pull
them apart by holding connectors themselves.

• Do not leave ignition key in a place where
temperature is high. High temperature may cause
damage to the transponder built in the ignition key.• Do not turn ignition switch to ON position by bringing
radio antenna close to coil antenna. Or, the
immobilizer control system may detect some
abnormal condition and prevent the engine from
starting.
General Description
Immobilizer Control System IntroductionS6RW0DA301001
The immobilizer control system is an anti-theft device that immobilizes the vehicle. It stops the engine from working
and prevents the vehicle from being stolen. It mainly consists of the following components. For immobilizer control
system components location, refer to “Immobilizer Control System Components Location”.
•ECM
• ICM with the built-in coil antenna
• Ignition key with the built-in transponder
A code called the transponder code is memorized in the transponder. And, the code is registered with ECM. Basically,
when the ignition switch is turned ON, ECM reads the code by the coil antenna. Then, if the code in transponder in the
ignition key does not match with the one registered with ECM, ECM stops the operation of the fuel injection so as not
to start up the engine and turns the immobilizer indicator light ON and OFF using CAN communication lines. (In
addition to the above operation, ECM also turns the immobilizer indicator light ON and OFF when some trouble is
detected in the keyless start system.)
On-Board Diagnostic System Description (Self-diagnosis Function)S6RW0DA301002
ECM diagnoses if there is any trouble with the immobilizer control system. The diagnostic information is stored as the
diagnostic trouble code (DTC) in ECM. To read the diagnostic information, use SUZUKI scan tool referring to “DTC
Check”.
With the ignition switch turned ON (but the engine at stop) regardless of the condition of the engine and emission
control system, ECM indicates whether there is any trouble with the immobilizer control system or not by either lighting
ON or flashing ON and OFF the immobilizer indicator light.
Immobilizer indicator light lights ON:
No trouble exists in the immobilizer control system. (After starting up the engine, the light turns OFF.)
Immobilizer indicator light flashes ON and OFF:
There is some trouble in the immobilizer control system or in the keyless start system. Its diagnostic information is
stored in ECM.

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)

Diagnostic Information and Procedures
Precautions in Diagnosing TroublesS6RW0DA504001
• The keyless start system executes data transmission/
reception by means of the radio wave. Therefore,
proper operation may not be obtained if use of the
door lock function and engine start function of the
keyless start system is attempted near the place
where strong radio wave is emitted (TV and radio
broadcasting stations, etc.).
• Diagnostic information stored in keyless start control
module memory can be checked only by key indicator
light.
• Be sure to use the trouble diagnosis procedure as
described in “Keyless Start System Check”. Failure to
follow it may result in incorrect diagnosis. (Some other
DTC may be stored by mistake in the memory of
keyless start control module during inspection.)
• Be sure to read“Precautions for Electrical Circuit
Service in Section 00” before inspection and observe
what is written there.
• Communication of ECM, TCM (A/T model), BCM,
ABS control module, 4WD control module (if
equipped), keyless start control module and
combination meter is established by CAN (Controller
Area Network). (For detail of CAN communication for
keyless start control module, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”.
• Replacement of the keyless start control module
When keyless start control module is replaced with
new one, make sure that register remote controller ID
code to keyless start control module correctly
according to “Registration Procedure for Remote
Controller ID Code”.• Keyless start control module substitution
When the keyless start control module used in
another vehicle was installed in the vehicle being
serviced, register the ID code of the remote controller
to the keyless start control module first and then the
following code.
– With immobilizer control system, register the
ignition key transponder code for the immobilizer
control system in ECM. For registration procedure
of that, refer to “Registration of the Ignition Key in
Section 10C”.
– Without immobilizer control system, register the
steering lock unit ID code in keyless start control
module. For registration procedure of that, refer to
“Keyless Start Registration”.
Self-Diagnosis FunctionS6RW0DA504002
The keyless start control module has self-diagnosis
function to monitor the system components and circuits
while the keyless start system is at work. When the
keyless start control module detects an abnormality in
the system, it saves the area where such abnormality
has occurred as a DTC in its memory. The DTC stored in
memory of the keyless start control module is indicated
by the key indicator light in the combination meter
flashing in a specific pattern. For DTC indication, refer to
“DTC Check” and for the clearing procedure, to “DTC
Clearance”.
Keyless Start System Diagnosis IntroductionS6RW0DA504003
To ensure that the trouble diagnosis is done accurately
and smoothly, observe “Precautions in Diagnosing
Troubles” and follow “Keyless Start System Check”.
