Kia Optima: Servicing The Electrical System
| 1. | Prior to servicing the
electrical system, be sure to turn off the ignition switch and disconnect
the battery ground cable.
|
| 2. | Attach the wiring harnesses
with clamps so that there is no slack. However, for any harness which passes
the engine or other vibrating parts of the vehicle, allow some slack within
a range that does not allow the engine vibrations to cause the harness to
come into contact with any of the surrounding parts and then secure the
harness by using a clamp.
|
| 3. | If any section of a wiring
harness interferes with the edge of a parts, or a corner, wrap the section
of the harness with tape or something similar in order to protect if from
damage.
|
| 4. | When installing any parts,
be careful not to pinch or damage any of the wiring harness.
|
| 5. | Never throw relays, sensors
or electrical parts, or expose them to strong shock.
|
| 6. | The electronic parts used
in the computer, relays, etc. are readily damaged by heat. If there is a
need for service operations that may cause the temperature to exceed 80°C
(176°F), remove the electronic parts before hand.
|
| 7. | Loose connectors cause
problems. Make sure that the connectors are always securely fastened.
|
| 8. | When disconnecting a connector,
be sure to grip only the connector, not the wires.
|
| 9. | Disconnect connector which
have catches by pressing in the direction of the arrows shown the illustration.
|
| 10. | Connect connectors which
have catches by inserting the connectors until they make a clicking sound.
|
| 11. | When using a circuit tester
to check continuity or voltage on connector terminals, insert the test probe
into the harness side. If the connector is a sealed connector, insert the
test probe through the hole in the rubber cap until contacts the terminal,
being careful not to damage the insulation of the wires.
|
| 12. | To avoid overloading the
wiring, take the electrical current load of the optional equipment into
consideration, and determine the appropriate wire size.
