PRECAUTIONS FOR HANDLING ELECTRICAL EQUIPMENT

To maintain the performance of the machine over a long period, and to prevent failures or troubles before they
occur, correct "operation", "maintenance and inspection" "troubleshooting", and "repairs" must be performed.
This section deals particularly with correct repair procedures for mechatronics components and is aimed at im-
proving the quality of repairs. For this purpose, it describes the working procedures in "Handling of electrical
equipment".

Handling wiring harnesses and connectors

• Wiring harnesses consist of wires connecting one compo-

nent to another component, connectors used for connect-
ing and disconnecting one wire from another wire, and pro-
tectors or tubes used for protecting the wires.

• Compared with other electrical components fitted in boxes

or cases, wiring harnesses are likely to be directly affected
by  rain  water,  heat,  or  vibration.  Furthermore,  during  in-
spection  and  repair  operations,  they  are  frequently  re-
moved and installed again, so they are likely to suffer de-
formation or damage. For this reason, it is necessary to be
extremely  careful  when  handling  and  maintenance  of  the
wiring harnesses.

• If AdBlue/DEF is spilled over wiring harness and connectors, it may cause corrosion and defective contact.

Be careful not to spill it over electrical equipment, wiring harness and connectors since AdBlue/DEF is
strongly corrosive to metal.

Main causes of failure in wiring harness

Defective contact of connectors (defective contact between male and female connectors)

Problems with defective contact are likely to occur because the
male connector is not properly inserted into the female connec-
tor,or because one or both of connectors are deformed or the
position is not correctly aligned, or because there is corrosion
or oxidization of the contact surfaces. The corroded or oxidized
contact surfaces may become shiny again (and contact may
become normal) by connecting and disconnecting the connec-
tors approximately 10 times.

Defective crimping or soldering of connectors

The pins of the male and female connectors are attached to
wires by crimping or soldering. If excessive force is applied to
the wire, the jointed portion (1) may become loose, and it may
result in a defective connection or breakage.
