2000 MITSUBISHI MONTERO Service Repair Manual

GENERAL -Precautions Before Service00-32
Other precautions:
DAvoid prolonged and repeated contact with oils,
particularly used engine oils.
DWear protective clothing, including impervious gloves
where practicable.
DAvoid contaminating clothes, particularly underpants, with
oil.
DDo not put oily rags in pockets, the use of overalls without
pockets will avoid this.
DDo not wear heavily soiled clothing and oil-impregnated
foot-wear. Overalls must be cleaned regularly and kept
separately from personal clothing.
DWhere 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.
DObtain First Aid treatment immediately for open cuts and
wounds.
DWash regularly with soap and water to ensure all oil is
removed, especially before meals (skin cleansers and
nail brushes will help). After cleaning, the application of
preparations containing lanolin to replace the natural skin
oils is advised.
DDo not use petrol, kerosine, diesel fuel, gas oil, thinners
or solvents for cleaning skin.
DUse barrier creams, applying them before each work
period, to help the removal of oil from the skin after work.
DIf skin disorders develop, obtain medical advice without
delay.

6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

2. Bolts marked with indications such as 4T or 7T are reinforced bolts. The larger the number, the
greater the bolt strength.
