Ohmmeter
The ohmmeter is used to measure the resistance be-
tween two points in a circuit, and is also used to check
for continuity and diagnosis of short circuits.
Caution
Do not attempt to connect the ohmmeter to
any circuit to which voltage is applied, be-
cause doing so may burn or otherwise dam-
age the ohmmeter.
PRECAUTION
Wiring Color Code
Two-color wires are indicated by a 2-letter symbol.
The first letter indicates the base color of the wire and
the second indicates the color of the stripe.

Inspection note
When checking the continuity or voltage with a cir-
cuit tester, insertion of the test probe into the recep-
tacle connector may open the fitting of the connector
and result in poor contact.
Therefore, insert the test probe only from the wire har-
ness side.
Replacement of Terminal
Use the appropriate tools to remove the terminal, as
shown in the figure.
When installing a terminal, be sure to press it in until
it locks securely.
< Female Type No.1 >
Insert a push-tool or thin piece of metal from the ter-
minal side of the connector, and then, with the lock-
ing tabs of the terminal pressed down, pull the
terminal out from the rear side.
< Female Type No.2>
