Checking the contact pressure of the terminal:
Prepare a spare male terminal. Insert it into a fe-
male terminal, and check for ample tension when in-
serting and after full engagement.

REPAIR METHOD OF CONNECTOR TERMINAL
(1)
If there is any dirt on the terminal, clean the contact
point using an air gun or cloth. Never rub the contact
point using sandpaper as the plating may come off.
(2)
If there is abnormal contact pressure, replace the
female terminal. If the male terminal is gold--plated
(gold color), use a gold--plated female terminal; if it
is silver--plated (silver color), use a silver--plated fe-
male terminal.
(3)
Damaged, deformed, or corroded terminals should
be replaced. If the terminal will not lock into the
housing, the housing may have to be replaced.
(e)
HANDLING OF WIRE HARNESS
(1)
If removing a wire harness, check the wiring and
clamping before proceeding so that it can be re-
stored in the same way.
(2)
Never twist, pull or slacken the wire harness more
than necessary.
(3)
The wire harness should never come into contact
with a high temperature part, or rotating, moving, vi-
brating or sharp--edged parts. Avoid contact with
panel edges, screw tips and other sharp items.
(4)
When installing parts, never pinch the wire harness.
(5)
Never cut or break the cover of the wire harness. If
it is cut or broken, replace it or securely repair it with
vinyl tape.
2.
CHECK OPEN CIRCUIT
(a)
For an open circuit in the wire harness in Fig. 1, perform
a resistance check (step b) or a voltage check (step c).
