PRECAUTIONS
Precaution for Multiport Fuel Injection System or Engine Control System
INFOID:0000000001606121
 Before connecting or disconnecting any harness connector for the
multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
 Before disconnecting pressurized fuel line from fuel pump to injec-
tors, be sure to release fuel pressure.
 Be careful not to jar components such as ECM and mass air flow
sensor.
Precaution for HosesINFOID:0000000001606122
HOSE REMOVAL AND INSTALLATION
 To prevent damage to rubber hose, do not pry off rubber hose with
tapered tool or screwdriver.
 To reinstall the rubber hose securely, make sure that hose insertion
length and orientation is correct. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against hose
stopper.)
HOSE CLAMPING
 If old rubber hose is re-used, install hose clamp in its original posi-
tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.

< BASIC INSPECTION >
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
lowing section illustrates ways to simulate the conditions/environment under which the owner experiences an
electrical incident.
The section is broken into the six following topics: Vehicle vibration
 Heat sensitive
 Freezing
 Water intrusion
 Electrical load
 Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
Connector & Harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
Sensor & Relay
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
Engine Compartment
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
 Connectors not fully seated.
 Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
 Wires laying across brackets or moving components.
 Loose, dirty or corroded ground wires.
 Wires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.
Behind the Instrument Panel
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.

PRECAUTIONS
General Refrigerant Precaution
INFOID:0000000001396430
WARNING:
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and oil manufacturers.
 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 (126° 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 suf-
focation.
 Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing systems with compressed air during repair. Some mixtures of air and HFC-134a (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 manu-
facturers.
Oil PrecautionINFOID:0000000001396431
 Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil
other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following 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 con-
necting the components. Connect all refrigerant loop components as quickly as possible to minimize the
entry of moisture into system.
- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without proper seal-
ing, oil will become moisture saturated and should not be used.
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental
system discharge occurs, ventilate work area before resuming service. Additional health and safety informa-
tion may be obtained from refrigerant and oil manufacturers.
 Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Precaution for Refrigerant ConnectionINFOID:0000000001396432

WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.
