Precautions
Precautions in Diagnosing TroubleS7RS0BA200001
• Diagnostic information stored in BCM memory can be cleared as well as checked by using SUZUKI scan tool.
Before using scan tool, read its Operator ’s (Instruction) Manual carefully to have good understanding as to what
functions are available and how to use it.
• Be sure to read “Precautions for Electrical Circuit Serv ice in Section 00” before inspection and observe what is
written there.
• Communication of ECM, TCM (if equipped), ABS/ESP ® control module, steering angle sensor (ESP ® model),
keyless start control module (if equipped), combinatio n meter and BCM is established by CAN (Controller Area
Network). For detail of CAN communication for BCM, refer to “CAN Communication System Description”.
Therefore, handle CAN communication line with care referr ing to “Precaution for CAN Communication System in
Section 00”.
General Description
BCM General DescriptionS7RS0BA201001
The Body electrical Control Module (BCM) is incorporated in junction block assembly. Do not attempt removal of BCM
from junction block assembly as it may cause contact failure.
The BCM incorporates relays and controllers which are used for the following systems and controls them.
• Power door lock
• Keyless entry (if equipped)
• Door lock function of keyle ss start system (if equipped)
• Rear wiper
• Combination meter
• Interior light
• Warning buzzer
• Rear end door window defogger and door mirror heater (if equipped)
• Rear end door opener
• Theft deterrent light
Also, the BCM has a function to cause the interior light and open door warning lamp in the combination meter to turn
off when any door is left open for longer than 15 minutes to reduce wasteful battery consumption.
In addition, it is possible to check operation of actuator whic h is controlled by BCM by using the output test function of
SUZUKI scan tool to operate actuator simulatively.

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)”.
