2007 KIA CARNIVAL Workshop Manual

1.Handling of Connector
a. Never pull on the wiring harness when disconnecting connectors.
b.When removing the connector with a lock, press or pull locking lever.
c.Listen for a click when locking connectors. This sound indicates that they are securely locked.
d.When a tester is used to check for continuity, or to measure voltage, always insert tester probe from wire
harness side.

e.Check waterproof connector terminals from the connector side. Waterproof connectors cannot be accessed from
harness side.
a.Use a fine wire to prevent damage to the terminal.
b. Do not damage the terminal when inserting the tester lead.
2. Checking Point for Connector
a. While the connector is connected:
Hold the connector, check connecting condition and locking efficiency.
b. When the connector is disconnected:
Check missed terminal, crimped terminal or broken core wire by slightly pulling the wire harness.
Visually check for rust, contamination, deformation and bend.
c. Check terminal tightening condition:
Insert a spare male terminal into a female terminal, and then check terminal tightening conditions.
d. Pull lightly on individual wires to ensure that each wire is secured in the terminal.
3.Repair Method of Connector Terminal
a. Clean the contact points using air gun and/or shop rag.

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
● CHECK OPEN CIRCUIT
1. Procedures for Open Circuit
a. Continuity Check
b. 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
When measuring for resistance, lightly shake the wire harness above and below or from side to side.
Specification (Resistance)
1Ω or less → Normal Circuit
1MΩ or Higher → 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 1MΩ 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.

b.Disconnect connector (B), and measure for resistance between connector (C) and (B1) and between (B2) and
(A) as shown in [FIG. 3].
In this case the measured resistance between connector (C) and (B1) is higher than 1MΩ and the open circuit
is between terminal 1 of connector (C) and terminal 1 of connector (B1).
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. 4].
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
a. Continuity Check with Chassis Ground
If short to ground circuit occurs as shown in [FIG. 5], the broken point can be found by performing Step 2
(Continuity Check Method with Chassis Ground) as shown below.

2.Continuity Check Method (with Chassis Ground)
Lightly shake the wire harness above and below, or from side to side when measuring the resistance.
Specification (Resistance)
1Ω or less → Short to Ground Circuit
1MΩ or Higher → Normal Circuit
a. Disconnect connectors (A), (C) and measure for resistance between connector (A) and Chassis Ground as
shown in [FIG. 6].
The measured resistance of line 1 and 2 in this example is below 1 Ω and higher than 1MΩ 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.
b. Disconnect connector (B), and measure the resistance between connector (A) and chassis ground, and
between (B1) and chassis ground as shown in [FIG. 7].
The measured resistance between connector (B1) and chassis ground is 1Ω or less. The short to ground circuit
is between terminal 1 of connector (C) and terminal 1 of connector (B1).
