Not Using SUZUKI Scan Tool
NOTE
In case of malfunction of temperature
selector, blower speed selector and air flow
selector, DTC can not be checked by the
following procedure. Use SUZUKI scan tool
for DTC check.
1) Light over sunload sensor vertically with an
incandescent light of approximately 100 W apart
from about 100 mm (3.94 in.).
NOTE
If sunload sensor is not lighted over with an
incandescent light, DTC of sunload sensor is
detected as current DTC even though there is
not any malfunction.
2) Set the following selectors to specified positions
below respectively with ignition switch off position.
• Temperature selector (1) is maximum cool
position
• Blower speed selector (2) is OFF position
• Air flow selector (3) is AUTO position
3) While pressing A/C switch (4) and air intake selector
(5) simultaneously, turn ignition switch to ON
position.
4) Wait for about 5 seconds (start of diagnosis).
5) Read flashing pattern of “FRE” (6) and “REC” (7)
indicator lights which represents DTC and write it
down.
NOTE
• When 2 or more current DTCs are
detected, only DTC having the highest
priority is indicated. Therefore, after
troubleshooting the malfunction, DTC
check has to be performed again to see if
any other DTC(s) is detected.
• Pressing “A/C” switch alternates display
of current DTC and history DTC. “A/C”
indicator light (8) remains off when display
is in current DTC mode and it lights up
when display is in history DTC mode.
• When a history DTC is indicated while 2 or
more history DTCs are detected, it is
possible to have other history DTC(s)
stored in HVAC control module displayed
by pressing the air intake selector.
Example: When inside air temperature sensor
circuit malfunction (Open) is set
Example: When VSS signal failure (Data error) is
set
6) After completing above check, turn ignition switch to
“OFF” position.
[A]: “REC” indicator light L: OFF
[B]: “FRE” indicator light a. About 0.5 seconds
H: ON b. About 2 seconds
[A]: “REC” indicator light a. About 0.5 seconds
[B]: “FRE” indicator light b. About 3 seconds
H: ON c. About 1.5 seconds
L: OFF

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.

• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal included in the
connector test adapter kit (special tool).
If contact tension is not enough, reform the terminal to
increase contact tension or replace it.
Special tool
(A): 09932–76010 Connector test adapter kit
• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an
intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wire broken inside the insulation. This condition could
cause a continuity check to show a good circuit, but if
only 1 or 2 strands of a multi-strand-type wire are
intact, resistance could be far too high.
Repair and Inspection Required after AccidentS6RW0D8204048
CAUTION!
• All air bag system components, including
the electrical harness (component
mounting points), must be inspected after
an accident. If any components are
damaged or bent, they must be replaced
even if air bag system activation did not
occur.
• Never use air bag system parts from
another vehicle.
• Do not attempt to service the parts below.
Service of these parts is by replacement
only.
– Driver / Passenger air bag (inflator)
modules
– Driver / Passenger side-air bag (inflator)
modules
– Driver / Passenger side curtain-air bag
(inflator) modules
– Driver / Passenger seat belt
pretensioners
– Forward impact-sensor
– Driver / Passenger side impact-sensors
–SDM
– Contact coil and combination switch
assembly
– Air bag wire harness in main harness,
instrument panel harness, floor harness,
passenger air bag harness, side-air bag
harness and side curtain-air bag
harness.
• Proper operation of the sensors and air
bag system requires that any repairs to the
vehicle structure return it to its original
production configuration.
