WARNING!
Handling of Rear End Door Balancer
(Damper)
• Handle balancer carefully. Do not scar or scratch exposed surface of its piston rod,
and never allow any paint or oil to stick to
its surface.
• Do not turn piston rod with balancer fully extended.
• Do not disassemble balancer (1) because its cylinder is filled with gas.
Discarding of Rear End Door Balancer
(Damper)
• The gas itself in balancer is harmless but it may issue out of the hole together with
chips generated by th e drill (2). Therefore,
be sure to wear goggle when drilling.
• Using a 2 to 3 mm (0.08 to 0.12 in.) drill (2),
make a hole to remove gas inside as
shown before discarding.

Installation
Reverse removal procedure noting the following.
• Tighten rear end door balancer bolt to specified torque.
Tightening torque
Rear end door balancer bolt (a): 23 N·m (2.3 kgf-
m, 17.0 lb-ft) • Secure wiring harness (1).
• Adjust door latch striker position by referring to “Rear
Door Lock Assembly Removal and Installation in
Section 9F”.
• Adjust door cushion so that door contacts body when closed.
• Apply sealant to contact face “A” of door hinge (1) and apply grease to rotating part “B” of hinge (1).
Specified sealant and grease.
“A”: Sealant 99000–31110 (SUZUKI Bond
No.1215)

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.

Inspection of BCM and its CircuitsS7RS0BA204018
BCM and its circuits can be checked at BCM wiring couplers by measuring voltage and resistance.
CAUTION!
BCM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to BCM
with couplers disconnected from it.

Voltage Check1) Disconnect negative (–) cable at battery.
2) Remove BCM (included in junction block assembly) refe rring to “BCM (Included in Junction Block Assembly)
Removal and Installation”.
3) Connect connectors to BCM (1) and junction block assembly (2).
4) Check voltage at each terminal number of couplers connected. For connector and terminal number, refer to “Connector Layout Diagram of BCM and Junction Block Assembly”.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is ON.
• Voltage with asterisk (*) can not be measured by voltmeter because it is pulse signal. Check it with oscilloscope if necessary.

Immobilizer Indicator Lamp Remains ON after Engine StartsS7RS0BA304007
Wiring Diagram
Refer to “Immobilizer Control S ystem Wiring Circuit Diagram”.
Circuit Description
When the ignition switch is turned ON, ECM read the code by the coil antenna from ignition key. Then if the code in
transponder in the key match with the one registered with ECM, transmits indication ON signal of immobilizer indicator
lamp to combination meter in order to turn immobilizer indicator lamp on. And then, combination meter turns
immobilizer indicator lamp on. When th e engine starts to run and no malfunction is detected in the system, ECM
transmits immobilizer indicator lamp indication O FF signal to combination meter in order to turn immobilizer indicator
lamp off. And then, comb ination meter turns immobilizer indicator lamp off, but if a malfunction was or is detected,
immobilizer indicator lamp is flashes ON and OF F, when ignition switch turn to ON position.
