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.

Diagnostic Information and Procedures
BCM Self-Diagnosis FunctionS7RS0BA204001
• BCM monitors conditions of the system components and its circuit with ignition switch turned to ON position. When
an abnormality in the system oc curs, the area where that abnormality lies is stored in the memory of EEPROM in
BCM.
• DTC can be checked in either one of following ways. – DTC can be checked by SUZUKI scan tool (2) connected to DLC (1).
– DTC can be read from flashing pattern of theft deterrent light (3). Also, DTC is displayed on combination meter
(4) at the same time.
