PRECAUTIONS
GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servicing
a vehicle. These general precautions apply to many of the service procedures described in this manual, and they
will not necessarily be repeated with each procedure to which they apply.
WARNING:
Whenever raising a vehicle for service, be sure to follow the instructions under “VEHICLE LIFTING
POINTS” on SECTION 0A.
When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for auto-
matic transmission vehicles), Keep hands, hair, clothing, tools, etc. away from the fan and belts
when the engine is running.
When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refriger-
cardiagn.com
ant), make sure that the area you work in is well-ventilated.
To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold,
tailpipe, muffler, etc.
New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new
or used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory ani-
mals. Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil,
wear a long-sleeve shirt and moisture-proof gloves (such as dish washing gloves) when changing
engine oil. If engine oil contacts your skin, wash thoroughly with soap and water. Launder any
clothing or rags if wet with oil, recycle or properly dispose of used oil and filters.
Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.
CAUTION:
Before starting any service work, cover fenders, seats and
any other parts that are likely to get scratched or stained
during servicing. Also, be aware that what you wear (e.g,
buttons) may cause damage to the vehicle’s finish.
cardiagn.com
Whenever you use oil seals, gaskets, packing, O-rings,
locking washers, split pins, self-locking nuts, and certain
other parts as specified, be sure to use new ones. Also, be-
fore installing new gaskets, packing, etc., be sure to remove
any residual material from the mating surfaces.

For vehicles equipped with fuel injection systems, never
disconnect the fuel line between the fuel pump and injector
without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.
cardiagn.com
Never connect any tester (voltmeter, ohmmeter, or whatev-
er) to electronic control unit when its coupler is discon-
nected. Attempt to do it may cause damage to it.
Never connect an ohmmeter to electronic control unit with
its coupler connected to it. Attempt to do it may cause dam-
age to electronic control unit and sensors.
Be sure to use a specified voltmeter/ohmmeter. Otherwise,
accurate measurements may not be obtained or personal
injury may result. If not specified, use a voltmeter with high-
impedance (M/V minimum) or a digital type voltmeter.

ELECTRICAL CIRCUIT INSPECTION
PROCEDURE
While there are various electrical circuit inspection methods, de-
scribed here is a general method to check its open and short circuit
by using an ohmmeter and a voltmeter.
1. Looseness of crimping
cardiagn.com
2. Open
3. Thin wire (single strand of wire)
Continuity check
1) Measure resistance between connector terminals at both ends
of the circuit being checked (between A-1 and C-1 in the figure).
If no continuity is indicated (infinity or over limit), that means that
the circuit is open between terminals A-1 and C-1.
Voltage check
If voltage is supplied to the circuit being checked, voltage check
can be used as circuit check.
1) With all connectors connected and voltage applied to the circuit
being checked, measure voltage between each terminal and
body ground.
GENERAL INFORMATION 0A-9
Voltage Between:
C-1 and body ground: Approx. 5V
B-1 and body ground: Approx. 5V
A-1 and body ground: 0V
Voltage Between:
0V
C-1 and body ground: Approx. 5V
B-1 and body ground: Approx. 5V 2V voltage drop
A-1 and body ground: Approx. 3V
cardiagn.com
SHORT CIRCUIT CHECK (wire harness to ground)
1) Disconnect negative cable from battery.
2) Disconnect connectors at both ends of the circuit to be checked.
NOTE:
If the circuit to be checked is connected to other parts, dis-
connect all connectors of those parts.
Otherwise, diagnosis will be misled.
3) Measure resistance between terminal at one end of circuit (A-1
terminal in figure) and body ground. If continuity is indicated, it
means that there is a short to ground between terminals A-1 and
C-1 of the circuit.

with the component or mating connector.

When using floor jack: In raising front or rear vehicle end off the floor by jacking, be sure
to put the jack against the center portion of front cross member (1)
or rear axle (2).
WARNING:
Never apply jack against suspension parts (i.e., stabi-
lizer, etc.) or vehicle floor, or it may get deformed.
If the vehicle to be jacked up only at the front or rear
end, be sure to block the wheels on ground in order to
ensure safety.
2 After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on
the vehicle raised on jack alone.
cardiagn.com
Front To perform service with either front or rear vehicle end jacked up,
be sure to place safety stands (1) under body so that body is se-
curely supported. And then check to ensure that body does not
slide on safety stands and the vehicle is held stable for safety’s
sake.
