PRECAUTIONS BEFORE SERVICE
m i
PROTECTING THE VEHICLE
If there is a likelihood of damaging painted or interior parts
during service operations, protect them with suitable covers
(such as seat covers, etc.).
> ’
REMOVAL AND DISASSEMBLY
When checking a malfunction, find the cause of the problem.
If it is determined that removal and/or disassembly is neces-
sary, perform the work by following the procedures con-
tained in this Service Manual.
If punch marks or mating marks are made to avoid error in
assembly and facilitate the assembly work, be sure to make
them in locations which will have no detrimental effect on
performance and/or appearances.
If an area having many parts, similar parts, and/or parts
which are symmetrical right and left is disassembled, be sure
to arrange the parts so that they do not become mixed during
the assembly process.
1. Arrange the parts removed in the proper order.
2. Determine which parts are to be reused and which are to
be replaced.
3. If bolts, nuts, etc., are to be replaced, be sure to use only
the exact size specified.
SPECIAL TOOLS
If other tools are substituted for the special tools to do serv-
ice or repair work, there is the danger that vehicle parts might
be damaged, or the mechanic might be injured; therefore,
be sure to use the special tool whenever doing any work for
which the use of one is specified,

PRECAUTIONS BEFORE SERVICE
WIRING HARNESES
1. Secure the wiring harnesses by using clamps so that there
is no slack. However, for any harness which passes to the
engine or other vibrating parts of the vehicle;allow some
slack within a range that does not allow the engine vibra-
tions to cause the harness to come into contact with any
of the surrounding parts. Then secure the harness. by
using a clamp.
In addition, if a mounting indication mark (yellow tape)
is on a harness, secure the indication mark in the speci-
fied location. (C 1638 1)
2. If any section of a wiring harness contacts the edge
of a part, or a corner, wrap the section of the harness
with tape or something similar in order to protect it
from damage.
3. When using a circuit tester to perform continuity or volt-
age checks on connector terminals, insert the test probe
from the harness side.
If the connector is a sealed connector, insert the test
probe into the hole in the rubber cap for the electrical
wires, being careful not to damage the wire insulation.
Continue to insert the test probe until it makes contact
with the terminal.
4. When disconnecting a connector, be sure to pull only the
connector, not the harness.
