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.
