General Information
The support rod must be inserted into the hole near the edge
of the hood whenever you inspect the engine compartment to prevent the
hood from falling and causing possible injury.
Make sure that the support rod has been released prior to
closing the hood. Always check to be sure the hood is firmly latched
before driving the vehicle. |
1. |
Inspection of parts
Each part, when removed, should be carefully on suspected for malfunction, deformation, damage, and other problems. |
2. |
Arrangement of parts
All disassembled parts should be carefully arranged for effective reassembly.
Be sure to separate and correctly identify the parts to be replaced from those that will be used again. |
3. |
Cleaning parts for reuse
All parts to be used again should be carefully and thoroughly cleaned by an appropriate method. |
1. |
Oil seals |
2. |
Gaskets |
3. |
O-rings |
4. |
Lock washers |
5. |
Cotter pins (split pins) |
6. |
Plastic nuts
Depending on their location. |
7. |
Sealant should be applied to gaskets. |
8. |
Oil should be applied to the moving components of parts. |
9. |
Specified oil or grease should be applied to the prescribed locations (oil seals, etc) before assembly. |
1. |
Be sure to disconnect the battery cable from the negative (-) terminal of the battery. |
2. |
Never pull on the wires when disconnecting connectors. |
3. |
Locking connectors will click when the connector is secure. |
4. |
Handle sensors and relays carefully. Be careful not to drop them against other parts. |
1. |
Basically, all measurements in this manual are taken with a tracking gauge. |
2. |
When a measuring tape is used, check to be sure there is no elongation, twisting or bending. |
3. |
For measuring dimensions, both projected dimensions and actual - measurement dimensions are used in this manual. |
1. |
These are the dimensions measured when the measurement points
are projected from the vehicle's surface, and are the reference
dimensions used for used for body alterations. |
2. |
If the length of the tracking gauge probes is adjustable,
measure it by lengthening one of two probes as long as the different
value in height of the two surface. |
1. |
These dimensions indicate the actual linear distance between
measurement points, and are used as the reference dimensions when a
tracking gauge is used for measurement. |
2. |
First adjust both probes to the same length (A=A') before measurement.
|
1. |
Check the terminal for tightness. |
2. |
Check terminals and wires for corrosion from battery electrolyte, etc. |
3. |
Check terminals and wires for open circuits. |
4. |
Check wire insulation and coating for damage, cracks and degrading. |
5. |
Check the conductive parts of terminals for contact with other metallic parts (vehicle body and other parts). |
6. |
Check grounded parts to verify that there is complete continuity between their attaching bolt(s) and the vehicle's body. |
7. |
Check for incorrect wiring. |
8. |
Check that the wiring is so clamped to the prevent contact
with sharp corners of the vehicle body, etc. or hot parts (exhaust
manifold, etc.) |
9. |
Check that the wiring is clamped firmly to provide enough
clearance from the fan pulley, fan belt and other rotating or moving
parts. |
10. |
Check that the wiring has a little space so that it can
vibrate between fixed and moving parts such as the vehicle body and the
engine. |
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.
|
If a large amount of unburned gasoline flows into the
converter, it may overheat and create a fire hazard. To prevent this
observe the following precations and explain them to your customer. |
1. |
Use only unleaded gasoline. |
2. |
Do not run the engine while the car is at rest for a long
time. Avoid running the engine at fast idle for more than 10 minutes and
idle speed for more than 20 minutes. |
3. |
Do not measure engine compression for an extended time.
Engine compression tests must be made as rapidly as possible. Remove the
fuel pump relay before performing a compression test. |
4. |
Do not dispose of used catalytic converter together with parts contaminated with gasoline or oil. |
