Precautions in Diagnosing Troubles for Combination MeterS6RW0D9300001
Combination meter uses signals (information) from each control module by CAN communication to control
speedometer, tachometer, fuel meter, engine coolant temp meter, warning light and indicator light (other than air bag
warning light, EPS warning light, headlight leveling warning light (if equipped), rear fog light indicator light (if
equipped), high beam indicator light and turn signal indicator light). Therefor, check that no DTC is detected in each
module before performing combination meter symptom diagnosis. If any DTC is detected, correct trouble indicated by
that DTC troubleshooting first.

Precautions
Precautions for Power Window Service (Pinching Prevention Function Model)S6RW0D9500001
WARNING!
When checking the pinching prevention function, never attempt intentionally to have your hand, arm
or any other part of the body pinched. Also, use full care not to have your body caught.

• Do not drop the power window regulator (motor) or expose it to a strong impact in any other way.
• Do not operate the motor unless the power window regulator (motor) is installed and ready to operate door glass.
• If any peripheral part has bean damaged, replace regulator (motor) as well depending on the damage condition.
• After replacing or disconnecting the driver side power window regulator (motor), power window main switch, battery
and/or fuse, make sure to execute the initial setting, (to have the door glass closed position learned) refer to “Power
Window Main Switch Initialization (Pinching Prevention Function Model)”.
General Description
Rear End Door Window Defogger System DescriptionS6RW0D9501001
The rear end door window defogger is controlled by BCM. For the BCM description refer to “BCM General Description
in Section 10B”.

CAUTION!
Upon completion of installation, note the
following.
• Sudden closing of door before adhesive is
completely set may cause glass to become
loose or to come off. Therefore, if door is
opened or closed before adhesive is
completely set, make sure to open all door
glasses and use proper care.
• If molding is not securely in place, hold it
down with a tape until adhesive is
completely set.
• Each adhesive has its own setting time.
• Be sure to refer to its maker’s instruction,
check setting time of adhesive to be used
and observe precautions to be taken
before adhesive is set.
• Refrain from driving till adhesive is
completely set so as to ensure proper and
sufficient adhesion.

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.
