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)”.
