Nissan Frontier D22. Manual - part 820

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system may include seat belt switch inputs and dual stage front air bag modules. If
equipped with dual stage front air bag modules, the SRS system uses the seat belt switches to determine the
front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and
whether the front occupants are belted or unbelted. Information necessary to service the system safely is
included in the SRS and SB section of this Service Manual.

The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.

WARNING:

●

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

●

The vehicle may be equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled
and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled
and could inflate for certain types of collision. After SRS maintenance or repair, make sure the
passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle
arrived for service.

Precautions for Working with HFC-134a (R-134a)

EJS001ZL

WARNING:

●

CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed, compressor failure is likely to occur. Refer to

MTC-4, "Contaminated Refrigerant"

. To

determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant
Recovery/Recycling Recharging equipment and Refrigerant Identifier.

●

Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor failure is likely to occur.

●

The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:

–

When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.

–

When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possi-
ble to minimize the entry of moisture into system.

–

Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. Without proper sealing, lubricant will become moisture saturated and should not be used.

–

Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove R-134a from the A/C system, using certified service equipment meeting require-
ments of SAE J2210 (R-134a recycling equipment), or J2209 (R-134a recovery equipment). If acci-

MTC-4

PRECAUTIONS

dental system discharge occurs, ventilate work area before resuming service. Additional health
and safety information may be obtained from refrigerant and lubricant manufacturers.

–

Do not allow lubricant (Nissan A/C System Oil Type R) to come in contact with styrofoam parts.
Damage may result.

Contaminated Refrigerant

EJS001ZM

If a refrigerant other than pure R-134a is identified in a vehicle, your options are:

●

Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant
into the atmosphere.

●

Explain that recovery of the contaminated refrigerant could damage your service equipment and refriger-
ant supply.

●

Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.

●

If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain-
ers. Do not recover contaminated refrigerant into your existing service equipment. If your facility
does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for avail-
able service. This refrigerant must be disposed of in accordance with all federal and local regulations. In
addition, replacement of all refrigerant system components on the vehicle is recommended.

●

If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact Nissan Cus-
tomer Affairs for further assistance.

General Refrigerant Precautions

EJS001ZN

WARNING:

●

Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.

●

Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.

●

Do not store or heat refrigerant containers above 52

°C (125°F).

●

Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.

●

Do not intentionally drop, puncture, or incinerate refrigerant containers.

●

Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.

●

Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.

●

Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and R-134a have been
shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety information may be obtained from refrigerant man-
ufacturers.

Precautions for Leak Detection Dye

EJS001ZO

●

The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.

●

Always wear fluorescence enhancing UV safety glasses to protect your eyes and enhance the visibility of
the fluorescent dye.

●

A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).

●

Always remove any dye from the leak area after repairs are complete to avoid a misdiagnosis during a
future service.

●

Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
of time cannot be removed .

●

Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).

●

Do not use more than one refrigerant dye bottle (1/4 ounce /7.4 cc) per A/C system.

PRECAUTIONS

MTC-5

MTC

●

Leak detection dyes for R-134a and R12 A/C systems are different. Do not use R-134a leak detection dye
in R-12 A/C system or R-12 leak detection dye in R-134a A/C systems or A/C system damage may result.

●

The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure
occurs.

A/C Identification Label

EJS001ZP

Vehicles with factory installed fluorescent dye have this identification
label on the underside of hood.

NOTE:
Vehicles with factory installed fluorescent dye have a green label.

Precautions for Refrigerant Connection

EJS001ZQ

A new type refrigerant connection has been introduced to all refrigerant lines except the following portion.

●

Thermal expansion valve connections.

FEATURES OF NEW TYPE REFRIGERANT CONNECTION

●

The O-ring is relocated in a groove for proper installation. This eliminates the chance of the O-ring being
caught in or damaged by the mating part. The sealing direction of the O-ring is now set vertically in rela-
tion to the contacting surface of the mating part to improve sealing characteristics.

●

The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facil-
itating piping connections.
