General Information

General Service Information

Protect the vehicle's protective painted surfaces and internal parts with work covers (seat covers) or tape (if damaged by tools) to prevent damage.

Before closing the engine hood, check the engine room for any tools or parts left.

At the same time as checking the defective part, determine the cause of the failure, determine whether it is necessary to remove or disassemble, and then work in the order of the workshop manual.

In order to prevent mis-assembly and to facilitate assembly work, punch marks or coincidence marks are applied to areas that do not adversely affect the function or appearance. When disassembling parts with a large number of parts and similar parts, arrange them so as not to be confused during assembly.

1)	Arrange the removed parts in order.

2)	Distinguish between replacement parts and reusable parts.

3)	When replacing bolts and nuts, be sure to use designated standard products.

3.	Special tools must be used for work instructing the use of special tools, as the parts may be damaged or damaged if the work is performed by using tools other than special tools.

Parts below must be replaced with new ones.

Gasket

Packing

Parts

1)	When replacing a new part, be sure to use genuine KIA parts.

2)	Use repair parts and the enclosed sets and kits.

3)	Parts supplied as maintenance parts may differ from parts assembled in a vehicle for the unification of parts, so check the parts catalog carefully before performing maintenance work.

6.	Be sure to turn the ignition switch "OFF" and disconnect the battery negative ( - ) cable before replacing or repairing electrical system parts.

7.	Be careful not to contact fuel and oil with rubber parts and hoses.

Inspection of Battery Terminals And Wiring

1.	Check that the battery terminals are solid.

2.	Check that the battery terminals and wiring are not corroded by battery electrolyte.

3.	Check the battery terminals and wiring for open circuits or the potential to open the circuit.

4.	Check the insulation and sheath of the wiring for damage, cracks, and deterioration of quality.

5.	Check if the terminals of the battery are in contact with other metal parts (car body or other parts).

6.	Make sure that the ground bolt and the body are in full contact.

7.	Check the wiring connection.

8.	Make sure that the wiring does not come into contact with sharp edges or hot parts (exhaust manifold, muffler, etc.) on the vehicle body.

9.	Make sure that the wiring is secured with sufficient clearance from rotating parts such as cooling fans and drive belts.

10.	Make sure that the wiring has an adequate vibration margin between vibration parts such as engines and fixed parts such as vehicle bodies.

Inspection of Fuse

1.	Check whether the fuse holder firmly secures the fuse.

2.	Verify that the fuse capacity is appropriate for each circuit.

Inspect the fuse for any signs of damage or malfunction.

The fuse has an inspection contact, allowing you to check its condition without removing it. To test the fuse, connect one contact of a test lamp to one side of the fuse (one at a time) and ground the other contact. If the lamp lights up, the fuse is proper. (Make sure the ignition switch is in the correct position to allow current to flow through the fuse circuit.)

4.	If the fuse is blown or damaged, refer to the electrical circuit diagram and inspect the components connected to the fuse.

5.	If no abnormalities are found in the components, thoroughly check the wiring circuit for any interference or damage.

When replacing a fuse, always use one with the specified rated capacity.

Using a fuse with a higher capacity than the specified one may cause damage to components or even a fire.

Inspection of Electrical System

Be sure to turn the ignition switch "OFF" and disconnect the battery negative ( - ) cable before replacing or repairing electrical system parts.

Disconnecting the battery negative ( - ) cable during system check will clear the error code stored in the engine control module (ECM).

Read the fault code before disconnecting the battery negative ( - ) cable.

2.	Fix the wiring with a clamp to prevent stretching.

3.	If the wiring contact with the edge or end of the part, wrap the interference part with tape to protect it from damage.

4.	When assembling vehicle parts, be careful not to damage the wiring.

5.	Be careful not to throw or cause shock to relays, sensors, electrical parts.

6.	ECMs and relays are easy to get damaged by overheating. At temperatures above 176°F (80°C), disconnect electrical parts before inspection work.

7.	Loose connector connection may cause failure, so make sure that the connector is properly connected.

8.	When disconnecting the connector, hold the connector body.

9.	When disconnecting the lockable connector, release the lock as shown below.

10.	When installing the lockable connector, push it in until a "click" sound is herd.

11.

When checking the energization or voltage of a connector terminal with a circuit tester, insert the probe from the harness side.

If the connector is a sealed type, be careful not to damage the insulation of the wiring, and insert the probe through the hole in the rubber sheath until the probe touches the terminal.
