Plastic Parts FinishingS6RW0D9C01002
Painting
Rigid or hard ABS plastic needs no primer coating.
General acrylic lacquers can be painted properly over hard ABS plastic in terms of adherence.
1) Use cleaning solvent for paint finish to wash each part.
2) Apply conventional acrylic color lacquer to part surface.
3) Follow lacquer directions for required drying time. (Proper drying temperature range is 60 – 70 °C (140 – 158 °F)).
Reference
Plastic parts employ not only ABS (Acrylonitrile Butadiene Styrene) plastic but also polypropylene, vinyl, or the like
plastic. Burning test method to identify ABS plastic is described below.
1) Use a sharp blade to cut off a plastic sliver from the part at its hidden backside.
2) Hold sliver with pincers and set it on fire.
3) Carefully observe condition of the burning plastic.
4) ABS plastic must raise readily distinguishable back smoke while burning with its residue suspended in air
temporarily.
5) Polypropylene must raise no readily distinguishable smoke while burning.

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.

Precautions
Precautions in Diagnosing TroublesS6RW0DA300001
• Before confirming the diagnostic trouble code (DTC),
do not disconnect connector from ECM, battery cable
from battery, ground wire harness, or main fuse. Such
disconnection will erase DTC stored in ECM.
• DTC stored in ECM memory can be checked as well
as cleared by using SUZUKI scan tool. Before using
SUZUKI scan tool, read its operator’s manual
carefully to know how to use it and what functions are
available.
• Be sure to read “Precautions for Electrical Circuit
Service in Section 00” before inspection.
• Communication of ECM, BCM, ABS control module,
TCM (if equipped), 4WD control module (if equipped),
keyless start control module (if equipped),
combination meter and DLC is established by CAN
(Controller Area Network). Therefore, handle CAN
communication lines with care referring to “Precaution
for CAN Communication System in Section 00”.
For CAN communication system, refer to description
on “CAN Communication System Description in
Section 1A”.
Precaution in Replacing ECMS6RW0DA300002
• If ECM is replaced with new or used one without
Immobilizer control function, the engine will not be
started. In case of the above, check if the newly
installed ECM has Immobilizer control function.
• After ECM is replaced with new one or used one, the
transponder code in the transponder built in the
ignition key has to be registered with ECM. Or, the
engine cannot be started up. For the registration
procedure, refer to “Procedure after ECM
Replacement”.
Precaution in Replacing Ignition KeyS6RW0DA300003
To register ignition key in case of replacing key(s) and/or
making spare key(s), the transponder code in the ignition
key is registered with ECM. Or the engine can not be
started up. For the registration procedure, refer to
“Registration of the Ignition Key”.
Precautions in Handling Immobilizer Control
System
S6RW0DA300004
• Do not turn ON ignition switch with ignition key in
contact with another one or quite close to another
one. Or, the immobilizer control system may detect
some abnormal condition and prevent the engine from
starting.
• Do not turn ON ignition switch by using ignition key
with any type of metal (1) wrapped its grip or in
contact with it. Or, the immobilizer control system may
detect some abnormal condition and prevent the
engine from starting.
