Precautions
Precautions in Diagnosing TroubleS6RW0DA200001
• 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 Service in Section 00” before inspection and observe what is
written there.
• Communication of ECM, TCM (A/T model), ABS control module, 4WD control module (if equipped), keyless start
control module (if equipped), combination 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 referring to “Precaution for CAN Communication System in Section 00”.
General Description
BCM General DescriptionS6RW0DA201001
The Body electrical Control Module (BCM) is
incorporated in junction block. Do not attempt removal of
BCM from junction block 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 (if equipped)
• Keyless entry (if equipped)
• Door lock function of keyless 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 (if equipped)
• Theft deterrent light
Also, the BCM has a function to cause the interior light
and open door warning light 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
which is controlled by BCM by using the output test
function of SUZUKI scan tool to operate actuator
simulatively.
