• 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 (if equipped), BCM, ABS or ESP
® control module (if equipped), 4WD control module
(if equipped), keyless start control module (if equipped), steering angle sensor (if equipped) and combination meter
is established by CAN (Controller Area Network).
Therefore, be sure to read “Precaution for CAN Communication System in Section 00” before inspection and handle
CAN communication line.
General Description
BCM General Description
S6JB0BA201001
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 / luggage room light
• Warning buzzer
• Rear end door window defogger and door mirror heater (if equipped)
• DRL (if equipped)
• Auto-on headlight (if equipped)
• Front fog light (if equipped)
• Theft deterrent light
• Clearance 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.
