PRECAUTIONS BEFORE SERVICE
PROTECTIN” THE VEHICLE NOODAAC
If theIre is a likelihood of damaging painted or interior parts
during service operations, protect them with suitable covers
(such as seat covers. fender 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 contained
in this, Workshop 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 service
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.
PARTS TO IBE REPLACED
If any of the following parts are removed, they must be
replaced with new parts.
1. Oil seals
2. Gaskets (except rocker cover gasket)
3. Packings
4. O-rings
5. Lock washers
6. Cotter pins
7. Self-locking nuts

INTRODUCTION - Towing and Hoisting
HOISTING
POST TYPE
15
Special care should be taken when raising the vehicle on a
frame contact type hoist. The hoist must be equipped with the
proper adapters in order to support the vehicle at the proper
locations. (See next page)
Conventional hydraulic hoists may be used after determining
that the adapter plates will make firm contact with the side
frame.
FLOOR JACK
A regular floor jack may be used under the front crossmember
or rear axle housing.
Caution
1. A floor jack must never be used on any part of the
underbody.
2. Do not attempt to raise one entire side of the vehicle by
placing a jack midway between front and rear wheels.
This practice may result in permanent damage to the
body.
EMERGENCY JACKING
Jack receptacles are located at the No. 2 crossmember and
rear axle housing to accept the jack supplied with the vehicle
for emergency road service. Always block the opposite wheels
and jack only on a level surface.

WIRING HARNESS - Troubleshooting 8-17
When a normal close type relay as illustrated here is checked,
there should be continuity between terminals (1) and (2) and
between terminals 3 and 4 when the relay is deenergized,
and the continuity should be lost between terminals 3 and 4
when the battery voltage is applied to the terminals 1 and 2. A
relay can be checked in this manner and it cannot be deter-
mine if a relay is okay or faulty by checking its state only when
it is deenergized (or energized).

CHECKING FUSES
A blade type fuse has test taps provided to allow checking of
the fuse itself without removing it from the fuse block. The
fuse is okay if the test light comes on when its one lead is
connected to the test taps (one at a time) and the other lead is
grounded.
(Change the ignition switch position adequately so that the
fuse circuit beomes live.)
CAUTIONS IN EVENT OF BLOWN FUSE
When a fuse is blown, there are two probable causes as follows
: One is that it is blown due to flow of current exceeding its rating.
The other is that it is blown due to repeated on/off current flowing
through it. Which of the two causes is responsible can be easily
determined by visual check as described below.
(1) Fuse blown due to current exceeding rating
The illustration shows the state of a fuse blown due to this
cause. In this case, do not replace the fuse with a new one
hastily since a current heavy enough to blow the fuse has
flowed through it. First, check the circuit for shorting and
check for abnormal electric parts. Only after the correction of
such shorting or parts, fuse of the same capacity should be
used as a replacement. Never use a fuse of lager capacity than
the one that has blown. If such a fuse is used, electric parts or
wirings could be damaged before the fuse blows in the event
an overcurrent occurs again.
(2) Fuse blown due to repeated current on/off
The illustration shows the state of a fuse blown due to re-
peated current on/off. Normally, this type of problem occurs
after fairly long period of use and hence is less frequent than
the above type. In this case, you may simply replace with a
new fuse of the same capacity.

2. CHECKING SHORTCIRCUITS
(1) Remove the blown fuse connect the test light to the
disconnected terminal. The test light should not come
on.
(2) Connect a lead wire of the test light to the power side
of the connector 0. The test light should not come on.
(3) Connect a lead wire of the test light to the load side of
the connector 0. The test light should come on and the
load light should also come on.
(4) Disconnect the load at the connector 0 and connect
the test light lead wire to the load side of the connector
CD.
The test light should come on and the load light should
also come on.
(5) Connect the test light lead wire to the switch side of
the connecotr 0. The test light should come on.
(6) If the test conforms to any of the above conditions,
there is a shortcircuit in the wiring between the
connector 0 and the connector 0.
3. CHECKING CONTINUITY
(I) When the switch is in the OFF position, the self power
test light should come on or the ohmmeter should read
0 R only when the terminals 2 and 3 are interconnect-
ed.
(2) When the switch is in the ON position, the self power
test light should come on or the ohmmeter should read
0 LR only when the terminals 1 and 4 are interconnect-
ed.
