HVAC SYSTEM (AUTO A/C)(DIAGNOSTIC)
General Description
2. General Description
A: CAUTION
1) Never connect the battery in reverse polarity.
Auto A/C control module may be destroyed instant-
ly.
2) Do not disconnect the battery terminals while the
engine is running.
A large counter electromotive force will be generat-
ed in the generator, and this voltage may damage
electronic parts such as auto A/C control module,
etc.
3) Before disconnecting the connectors of each
sensor and the auto A/C control module, be sure to
turn off the ignition switch.
Auto A/C control module may be damaged.
4) Every A/C-related part is a precision part. Do not
drop them.
5) Airbag system wiring harness is routed near the
A/C control panel (auto A/C control module) and
junction box.
CAUTION:
For airbag system, yellow-colored wiring har-
ness and connectors are all used. Do not use
the electrical test equipment on these circuits.
Be careful not to damage the airbag system
wiring harness when servicing the A/C control
panel (auto A/C control module) and junction
box.
B: INSPECTION
Before performing the diagnosis, check the follow-
ing items which might affect A/C system problems.
1. BATTERY
1) Measure battery voltage and specific gravity of
electrolyte.
Standard voltage: 12 V
Specific gravity: More than 1.260
2) Check the condition of the fuses for A/C system
power supply and other fuses.
3) Check the condition of harness and harness
connector connections.
2. ASPIRATOR HOSE
1) Turn the ignition switch to ON, and press the A/
C switch.
2) Turn the temperature control dial at maximum
hot position.
3) Press the defroster switch.
4) Turn the fan speed control dial to 4th position.5) Approach a strip of paper (b) in front of the in-ve-
hicle sensor suction port (a) located in the instru-
ment lower cover, and check that air is being
sucked into the port by seeing the paper moving to-
wards port.
NOTE:
Be careful not to let the paper get sucked into port.
6) If the paper does not move at all, remove the in-
strument panel lower cover
for improper connection of the aspirator hose (a),
in-vehicle sensor and heater unit, and repair them if
necessary.
3. A/C LINE
Check the connection for A/C line (A) and lower
side high-pressure pipe.
4. CONTROL LINKAGE
1) Check the state of mode door linkage.
2) Check the state of air mix door linkage.
3) Check the state of intake door linkage.

AIRBAG SYSTEM
General Description
B: CAUTION
When servicing a vehicle, be sure to turn the ig-
nition switch to OFF, disconnect the ground cable
from battery, and wait for more than 20 seconds
before starting work.
The airbag system is fitted with a backup power
source. If the airbag system is serviced within 20
seconds after the ground cable is disconnected, it
may inflate.
If the airbag warning light illuminates, repair the
vehicle immediately. Airbag or pretensioner may in-
flate incorrectly, or not inflate in collision.
If sensors, airbag module, airbag control module,
pretensioner or harness are deformed or damaged,
replace them with new parts.
When checking the airbag system, be sure to
use a digital circuit tester.
Infinitesimal electric current in an analog circuit
tester may cause the airbag to activate erroneous-
ly. When checking, use a test harness (1). Do not
directly apply the tester probe to any connector ter-
minal of the airbag. Damage to the connector termi-
nal may cause the airbag to activate erroneously.
Do not check continuity of either of the airbag
modules for driver, passenger or side, or preten-
sioner.

Airbag Module Disposal (Deployment Processing On Vehicle)
11.Airbag Module Disposal (De-
ployment Processing On Ve-
hicle)
A: OPERATION
CAUTION:
Do not discard an undeployed airbag mod-
ules because it may cause a serious personal
injury when accidentally deployed.
As a rule, the airbag module should be de-
ployed while still installed in the vehicle. Do not
remove the airbag modules unless necessary.
Deployment of the airbag module should be
done on a flat place free from any possible dan-
ger. Avoid deploying outdoors during rainy or
windy weather.
Deploying the airbag module causes a high
explosive noise, be sure to warn people in the
area, and do not allow anyone within a 5 m (16
ft) radius of the disposal site.
Some smoke will be emitted from deployment
of the airbag module. Therefore, it must be de-
ployed in a well-ventilated place with no smoke
detector nearby.
Wear protective gloves, safety goggles and
earplugs during this operation. Wash your hands
afterwards.
After deployment, the airbag module will be
especially hot, leave it unattended for 40 min-
utes, and then discard it.
Do not let water get on the deployed airbag
module.
Wrap the deployed airbag module in an air-
tight vinyl bag, and discard it.
If circumstances do not permit the airbag
module deployment, contact the SUBARU deal-
er.
