1. Before connecting or disconnecting any harness connector for multiport fuel injection system or ECM (ECCS control module):
Turn the ignition switch to the "OFF" position.
Disconnect the negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure.
3. Be careful not to jar components such as ECM and mass air flow sensor.
Precautions For Three Way Catalyst
If a large amount of unburned fuel flows into the Catalyst, the Catalyst temperature will be excessively high. To prevent this, follow the procedure below:
^
Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
^
When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary.
^
Do not run engine when the fuel tank level is low, otherwise the engine may misfire causing damage to the Catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe.
Precautions For Engine Oils
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact with used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
^
Avoid prolonged and repeated contact with oils, particularly used engine oils.
^
Wear protective clothing, including impervious gloves where practicable.
^
Do not put oily rags in pockets.
^
Avoid contaminating clothes, particularly underpants, with oil.
^
Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly.
^
First Aid treatment should be obtained immediately for open cuts and wounds.
^
Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
^
Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the
natural skin oils which have been removed.
^
Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or solvents for cleaning skin.
^
If skin disorders develop, obtain medical advice without delay.
^
Where practicable, degrease components prior to handling.
^
Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility
should be provided.
Precautions For Fuel
Use unleaded gasoline with an octane rating of at least 87 AKI(Anti-Knock Index) number (research octane number 91).
CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst.
Using fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.
