Blower Motor Controller InspectionS6RW0D7226012
1) Check internal circuit of controller for resistance as
follows.
a) Measure resistance between “1” terminal and “2”
terminal of blower motor controller.
Blower motor controller resistance
“1” – “2”: approximately 10 kΩ
If resistance does not meet above specification,
replace blower motor controller.
b) Using ohmmeter, connect its positive terminal to
“3” terminal of blower motor controller and
negative terminal to “1” terminal of blower motor
controller and check that there is no continuity.
2) Check controller for operation as follows.
a) Using bulb (3.4 W) (5) and service wire, connect
battery positive terminal to “3” terminal of blower
motor controller as shown in figure.
b) Using service wire, connect battery negative
terminal to “1” terminal of blower motor
controller.
c) Arrange 3 new 1.5 V batteries (6) in series
(check that total voltage is 4.5 – 5.0 V) and
connect its positive terminal to “2” terminal of
blower motor controller and negative terminal to
“1” terminal of blower motor controller.
Then, check that bulb lights. If bulb does not light
under the above conditions, replace blower
motor controller.

Downloaded from www.Manualslib.com manuals search engine 8A-3 Seat Belts:
Seat Belt with ELR
The seat belt with emergency locking retractor (ELR) is
designed so that it locks immediately (to prevent the
webbing from being pulled out of the retractor any
further) when any of the following items is detected as
exceeding each set value;
• Speed at which the webbing is pulled out of the
retractor.
• Acceleration or deceleration of the vehicle speed.
• Inclination.
Seat Belt with A-ELR
The automatic and emergency locking retractor (A-ELR)
works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an
Automatic Locking Retractor (ALR) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out
from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further,
unless it is wound all the way back into the retractor,
which releases the lock and allows the webbing to be
pulled out.
Seat Belt with ELR and Pretensioner
The seat belt with ELR and a pretensioner has a
pretensioner mechanism which operates in linkage with
the air bag in addition to the described ELR.The pretensioner is incorporated in retractor and
controlled by SDM as one of air bag system
components. It will be activated at the same time as the
driver and passenger air bag module when an impact at
the front of vehicle exceeds the specified value.
When servicing seat belt (retractor) with pretensioner, be
sure to observe all WARNINGS and CAUTIONS and
“Precautions on Service and Diagnosis of Air Bag
System in Section 8B”.
CAUTION!
Do not reuse the seat belt pretensioner
(retractor) that has activated. Replace it with
a new seat belt and buckle together as a set.
For checking procedure of its activation,
refer to “Repair and Inspection Required after
Accident in Section 8B”.

Seat Belt Remainder
When driver’s seat belt is unfastened (under the
following conditions), seat belt reminder light inform that
driver’s seat belt is unfastened. Seat belt reminder light
located in combination meter located inside BCM
operate as follows:
• Seat belt reminder light comes on when driver’s seat
belt is unfastened while ignition key switch is at ON
position.
Diagnostic Information and Procedures
Repair and Inspection Required after AccidentS6RW0D8104001
After an accident, whether the seat belt pretensioner has been activated or not, be sure to perform checks and repairs
described on “Repair and Inspection Required after Accident in Section 8B”.

• Never attempt to disassemble or repair the
retractor (seat belt pretensioner). If any
abnormality is found, be sure to replace it
with new one as an assembly.
• Be sure to read “Precautions on Service
and Diagnosis of Seat Belt” before starting
to work and observe every precaution
during work. Neglecting them may result in
personal injury or unactivation of the seat
belt pretensioner when necessary.

used.Rear Seat Belt InspectionS6RW0D8106006
WARNING!
Be sure to read “Precautions on Service and
Diagnosis of Seat Belt” before starting to
work and observe every precaution during
work.

• Check the rear seat belt in the same way as “Front
Seat Belt Inspection”.
• As to seat belts with A-ELR, check them as follows.
– With vehicle at stop, pull seat belt all the way out,
let it retract a little and try to pull it. It should not be
pulled out, that is, it should be locked where
retracted.
– Let seat belt retract to its original state. Next, pull it
half way out, let it retract a little and try to pull it
again. It should be pulled out smoothly, that is it
should not be locked at this time.

Precautions
Precautions on Service and Diagnosis of Air
Bag System
S6RW0D8200004
WARNING!
• If the air bag system and another vehicle
system both need repair, SUZUKI
recommends that the air bag system be
repaired first, to help avoid unintended air
bag system activation.
• Do not modify the steering wheel,
dashboard, both front seat or any other on
or around air bag system components.
Modifications can adversely affect air bag
system performance and lead to injury.
• Be sure to follow the procedures described
in this section. Failure to follow
procedures could result in possible air bag
system activation, personal injury or
unneeded air bag system repairs.

• WARNING / CAUTION labels are attached on each
part of air bag system components (SDM, air bag
(inflator) modules and seat belt pretensioners). Be
sure to follow the instructions.
• Many of service procedures require disconnection of
“A/B” fuse and air bag (inflator) module(s) (driver
module, passenger module, side modules and curtain
modules) from initiator circuit to avoid an accidental
deployment.
• Do not apply power to the air bag system unless all
components are connected or a diagnostic flow
requests it, as this will set a DTC.
• The “Air Bag Diagnostic System Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning light operation and will lead you to the
correct flow to diagnose any air bag malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
• Never use air bag component parts from another
vehicle.
• If the vehicle will be exposed to temperatures over 93
°C (200 °F) (for example, during a paint baking
process), remove the air bag system components
beforehand to avoid component damage or
unintended system activation.• When handling the air bag (inflator) modules (driver
module, passenger module, side modules and curtain
modules), seat belt pretensioners (driver module and
passenger module), SDM, forward impact-sensor or
side impact-sensor be careful not to drop it or apply
an impact to it. If an excessive impact was applied
(e.g., SDM, forward impact-sensor are dropped, air
bag (inflator) module is dropped from a height of 90
cm (3 ft) or more, seat belt pretensioner (retractor
assembly) is dropped from a height of 30 cm (1 ft) or
more), never attempt disassembly or repair but
replace it with a new one.
• When using electric welding, be sure to disconnect air
bag (inflator) module connectors (driver module,
passenger module, side modules and curtain
modules) and seat belt pretensioner connectors
(driver module and passenger module) respectively.
• When applying paint around the air bag system
related parts, use care so that the harness or
connector will not be exposed to the paint mist.
• Never expose air bag system component parts
directly to hot air (drying or baking the vehicle after
painting) or flames.
WARNING!
When performing service on or around air
bag system components or air bag wiring,
follow the procedures listed in “Disabling Air
Bag System” to temporarily disable the air
bag system.
Failure to follow procedures could result in
possible air bag system activation, personal
injury or unneeded air bag system repairs.

Precautions on Handling and Storage of Air Bag
System Components
S6RW0D8200002
SDM
WARNING!
Never power up air bag system when SDM is
not rigidly attached to the vehicle. Otherwise,
personal injury may result.

CAUTION!
After detecting one time of such collision as
to meet deployment conditions, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.
