Fuel System 95 General Information
3. Repair Method of Connector Terminal
a. Clean the contact points using air gun and/or
shop rag.
✍
NOTICE
Never use sand paper when polishing the
contact points, otherwise the contact point may
be damaged.
b. In case of abnormal contact pressure, replace the
female terminal.
Wire Harness Inspection Procedure
.
1. Before removing the wire harness, check the wire
harness position and crimping in order to restore it
correctly.
2. Check whether the wire harness is twisted, pulled or
loosened.
3. Check whether the temperature of the wire harness
is abnormally high.
4. Check whether the wire harness is rotating, moving
or vibrating against the sharp edge of a part.
5. Check the connection between the wire harness and
any installed part.
6. If the covering of wire harness is damaged; secure,
repair or replace the harness
Electrical Circuit Inspection Procedure
1. Procedures for Open Circuit
• Continuity Check
• Voltage Check
If an open circuit occurs (as seen in [FIG. 1]), it can
be found by performing Step 2 (Continuity Check
Method) or Step 3 (Voltage Check Method) as shown
Below
2. Continuity Check Method
✍
NOTICE
When measuring for resistance, lightly shake the
wire harness above and below or from side to side.

Specification (Resistance)
1Ω or less →
Normal Circuit
1

Open Circuit
--------------------------------------------------------------------
a. Disconnect connectors (A), (C) and measure
resistance between connector (A) and (C) as
shown in [FIG. 2].
In [FIG.2.] the measured resistance of line 1 and
2 is higher than 1
㏁
and
below 1 Ω respectively.
Specifically the open circuit is line 1 (Line 2 is
normal). To find exact break point, check sub line
of line 1 as described in next step.
