Theft Deterrent LightS7RS0BA201003
The information display or clock (1) of this vehicle includes a theft deterrent light (2) for the theft preventive purpose.
The BCM makes the theft deterrent light flash at certain interval s after the ignition switch is turned off until it is turned
on again. Also, to check DTCs stored in BCM without usin g a SUZUKI scan tool when diagnosing troubles, it is
possible to identify them by flashing patterns of the theft deterrent light.
Security Alarm Description (If Equipped)S7RS0BA201004
Operation
The security alarm system provides a warning of an abnormal condition to those who are around. Its operation is as
follows. While the system is in the stand- by mode (when 20 seconds or more elapsed after the door is locked using a
keyless entry transmitter or door request switch), BCM monitors door lock status, door switch status and battery power
supply voltage. When it detects an abnormal condition (door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily), it activates the
warning buzzer (located in BCM), theft deterr ent light, hazard warning relay and horn relay.
The security alarm system has 2 selectable modes.
• A mode: No operation
• B mode: Theft deterrent light blinks, hazard warning lights blink, warning buzzer (located in BCM) sounds and horn
sounds
When B mode is selected and the door is locked using keyl ess entry transmitter or door request switch, the theft
deterrent light (1) flashes at 0.1 second interval for 20 seconds and the se curity alarm system is set to the stand-by
mode (2). Once it is se t to the stand-by mode, the theft deterrent light blinks at 2 second intervals.
When the system is set to stand-by mode and the door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily, the alarm devices
operate according to the selected mode as described above.
The alarm stops under either of the following conditions.
• Ignition switch is turned ON
• A certain time has elapsed since the alarm started
For selection of the mode of the security alarm system , refer to “Security Alarm Mode Selection Procedure (If
Equipped)”.

Keyless Start System
General Description
Keyless Start System DescriptionS7RS0BA501001
Keyless start system consisting of the parts shown below has three functions as described below.
• Keyless engine start function:With the remote controller which has been registered in the keyless start control module carried with oneself, the
engine can be started without using the ignition key.
• Door lock function: Pushing the request switch incorporated in the outside handl e of the driver side door, passenger side door or rear
end door while carrying the remote controller which has been registered in the keyless start control module, doors
can be locked or unlocked.
• Keyless entry system function: It is possible to lock or unlock doors by push ing the lock or unlock button of remote controller.
The keyless start control module can accept regi stration of up to four remote controllers.

Keyless Engine Start FunctionS7RS0BA501003
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 signa l in the vehicle compartment. When the remote controller
(5) receives the request signal from th e 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
lamp (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 posit ion in this state, ID codes of ECM and keyless start control
module are compared through CA N communication (immobilizer function). Wh en 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 lamp in t he combination meter light in red to warn the driver that
it is not possible to turn the ignition knob switch. Also, 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 light in the combination mete r flash to warn the driver that it is not possible to start the
engine.

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.
