Removal of Manifold Gauge Set
WARNING!
High pressure side is under high pressure.
Therefore, be careful not to get injured
especially on your eyes and skin.

For the A/C system charged with the specified amount of
refrigerant, remove manifold gauge set as follows:
1) Close low pressure side valve of manifold gauge set. (The high pressure side valve is closed continuously
during the process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves. This operation must be performed quickly.
5) Put caps on service valves.
Check A/C System for Refrigerant Leaks
Whenever a refrigerant leak is suspected in the system
or any service operation has been performed which may
result in malfunction of lines and connections, it is
advisable to check for leaks.
Common sense should be used during refrigerant leak
test, since the need and extent of any such test will, in
general, depend upon the nature of a complaint and the
type of a service performed on the system.
Liquid leak detector
WARNING!
• To prevent explosions and fires, make sure that there are no flammables in the vicinity.
• When the refrigerant exposed to fire, it turns into a poisonous gas (phosgene). Do
not inhale this gas.

There is a number of fittings and places throughout the
A/C system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question
with a swab, such as attached to the cap of a vial,
bubbles will form within seconds if there is a leak.
For confined areas, such as sections of the evaporator
and condenser, an electronic (refrigerant) leak detector
is more practical fo r determining leaks.

Condenser Assembly On-Vehicle InspectionS7RS0B7216002
Check the followings.
• Clog of condenser fins If any clog is found, cond enser fins should be washed
with water and should be dried with compressed air.

• Condenser fittings for leakage. If any defects are found, repair or replace condenser.
Condenser Assembly Removal and InstallationS7RS0B7216003
CAUTION!
Do not damage condenser fins. If condenser
fin is bent, straighten it by using flat head
screwdriver or pair of pliers.

Removal
1) Recover refrigerant from A/C system referring to “Operation Procedure for Refrigerant Charge”.

Precautions in Diagnosing TroubleS7RS0B7220002
• Do not disconnect couplers from HVAC control module, battery cable from battery, HVAC control module ground
wire harness from body or main fuse before confirming diagnostic information (diagnostic trouble code) stored in
HVAC control module memory.
• Diagnostic information (diagnostic trouble code) stored in HVAC control module can be checked by display of HVAC
control module. Also, it can be checked by using SU ZUKI scan tool. Before checking diagnostic information
(diagnostic trouble code), read this manual and operator's manual for SUZUKI scan tool to know how to read
diagnostic information (diagnostic trouble code).
• When trouble is diagnosed using diagnostic information (diagnostic trouble code) on display of HVAC control
module, keep in your mind that each diagnostic inform ation (diagnostic trouble code) has priority, and only
diagnostic information (diagnostic troub le code) which has the highest priority is indicated. Therefore, after
troubleshooting the malfunction, make sure if there exists any other diagnostic information (diagnostic trouble
code).
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” before inspection.
Precautions on Servicing A/C SystemS7RS0B7220003
Refer to “Precautions on Servicing A/C System”.
General Description
Auto A/C System DescriptionS7RS0B7221001
The automatic type air conditioning system (auto A/C) is pr ovided with the function to automatically control the inside
air temperature, fan speed, air flow outl et direction and air intake position by HVAC control module in addition to
functions of the manual type air conditioning system (manua l A/C). Once the inside air temperature is set using the
temperature selector, HVAC control module automatically controls the inside air temperature at the constant level at all
times based on the inside air temperature, outside ai r temperature, amount of sunlight and engine coolant
temperature detected respectively by the inside air te mperature sensor, outside air temperature sensor, sunload
sensor and ECT sensor. At this time, “FULL AUTO A/ C” appears on the display of HVAC control module.
With the air intake selector pushed in the above state, it is possible to select any position of the air intake actuator.
Then, “FULL AUTO A/C” on the display changes to “AUTO A/C”.

Not Using SUZUKI Scan Tool
Current DTC mode1) Light over sunload sensor vertically with an incandescent lamp of approximately 100 W apart
from about 100 mm (3.94 in.).
NOTE
If sunload sensor is not lighted over with an
incandescent lamp, DTC B1504 is detected
as current DTC even though there is not any
malfunction.

2) Start engine.
3) Wait for 20 seconds or more after engine started and set temperature selector to 25 °C (77 °F).
4) Push AUTO switch (1) and defroster switch (2) at the same time.
5) Check DTC (3).
NOTE
• DTC flashes for 15 seconds. After that, the normal display is rest ored. To have DTC
displayed again, repeat the procedure from
Step 4.
• When more than two 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.

History DTC mode
1) Turn ignition switch to ON position.
2) Set temperature selector to 25 °C (77 °F).
3) Push AUTO switch (1) and MODE (air flow) selector

4) Check DTC (4).
NOTE
Each DTC item is displayed (lights up) for 4
seconds.
When HVAC control module detects 2 or
more DTC items, each one is displayed once
starting from the one of higher priority order.
After all DTC items being detected have been
displayed, “Ed” (3) appears on display of
HVAC control module and normal display is
restored. “Ed” means that all DTC items have
been displayed.

DTC ClearanceS7RS0B7224004
NOTE
Only history DTC(s) can be cleared. Current
DTC(s) can not be cleared unless the
problem(s) is fixed.

Using SUZUKI Scan tool
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) (1) located on underside of instrument panel
at driver’s seat side.

Precautions on Service and Diagnosis of Seat
Belt
S7RS0B8100001
WARNING!
If replacing seat belt is necessary, replace
buckle and seat belt assembly together as a
set. This is for the reason of ensuring locking
of tongue plate with buckle. If these parts are
replaced individually, such a locking
condition may become unreliable. For this
reason, SUZUKI will supply only the spare
buckle and seat belt assembly in a set part.

Before servicing or replacing seat belts, refer to the
following precautionary items.
• Seat belts should be normal relative to strap retractor and buckle portions. • Keep sharp edges and damaging objects away from
belts.
• Avoid bending or damaging any portion of belt buckle or latch plate.
• Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)
• When installing a seat belt anchor bolt, it should be tightened by hand at first to prevent cross-threading
and then to specified torque.
• Do not attempt any repair s on retractor mechanisms
or retractor covers. Replace defective assemblies with
new replacement parts.
• Keep belts dry and clean at all times.
• If there exist any parts in question, replace such parts.
• Replace belts whose webbing is cut or otherwise damaged.
• Do not put anything into trim panel opening which seat belt webbing passes through.
