3. Repair Method of Connector Terminal

a. Clean the contact points using air gun and/or shop rag.

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

• CHECK OPEN CIRCUIT

1. Procedures for Open Circuit



Continuity Check



Voltage Check

If an open circuit occurs (as seen in Fig. 9), it can be found by performing Step 2 (Continuity Check
Method) or Step 3 (Voltage Check Method).

NOTE:

Never use sand paper when polishing the contact points, otherwise
the contact point may be damaged.

2. Continuity Check Method

Specification (Resistance)

1ohms or less --> Normal Circuit

1ohms or Higher --> Open Circuit

a. Disconnect connectors (A), (C) and measure resistance between connector (A) and (C) as shown in

Fig. 10.

In Fig. 10 the measured resistance of line 1 and 2 is higher than 1MQ and below 1Q 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.

b. Disconnect connector (B), and measure for resistance between connector (C) and (B1) and between

(B2) and (A) as shown in Fig. 11.

In this case the measured resistance between connector (C) and (B1) is higher than 1MQ and the
open circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).

NOTE:

When measuring for resistance, lightly shake the wire harness above and
below or from side to side.

3. Voltage Check Method

a. With each connector still connected, measure the voltage between the chassis ground and terminal

1 of each connectors (A), (B) and (C) as shown in Fig. 12.

The measured voltage of each connector is 5V, 5V and 0V respectively. So the open circuit is
between connector (C) and (B).

• CHECK SHORT CIRCUIT

1. Test Method for Short to Ground Circuit



Continuity Check with Chassis Ground

If short to ground circuit occurs as shown in Fig. 13, the broken point can be found by performing Step 2
(Continuity Check Method with Chassis Ground).

2. Continuity Check Method (with Chassis Ground)

Specification (Resistance)

1ohms or less --> Short to Ground Circuit

1M ohms or Higher --> Normal Circuit

a. Disconnect connectors (A), (C) and measure for resistance between connector (A) and Chassis

Ground as shown in Fig. 14.

The measured resistance of line 1 and 2 in this example is below 1Q and higher than 1MB
respectively. Specifically the short to ground circuit is line 1 (Line 2 is normal). To find exact
broken point, check the sub line of line 1 as described in the following step.

NOTE:

Lightly shake the wire harness above and below, or from side to side when
measuring the resistance.
