ventilated.
• To avoid getting burned, keep away from
hot metal parts such as the radiator,
exhaust manifold, tail pipe, 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 animals. 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.

Repair Instructions
Electrical Circuit Inspection ProcedureS6RW0D0006001
While there are various electrical circuit inspection
methods, described here is a general method to check
its open and short circuit by using an ohmmeter and a
voltmeter.
Open Circuit Check
Possible causes for the open circuit are as follows. As
the cause is in the connector or terminal in many cases,
they need to be checked particularly carefully.
• Loose connection of connector
• Poor contact of terminal (due to dirt, corrosion or rust
on it, poor contact tension, entry of foreign object etc.)
• Wire harness being open
When checking system circuits including an electronic
control unit such as ECM, TCM, ABS control module,
etc., it is important to perform careful check, starting with
items which are easier to check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit
being checked for loose connection. Also check lock
condition of connector if equipped with connector
lock.
3) Using a test male terminal, check both terminals of
the circuit being checked for contact tension of its
female terminal. Check each terminal visually for
poor contact (possibly caused by dirt, corrosion, rust
entry of foreign object, etc.). At the same time, check
to make sure that each terminal is locked in the
connector fully.4) Using continuity check or voltage check the following
procedure, check the wire harness for open circuit
and poor connection with its terminals. Locate
abnormality, if any.
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”.
2) Disconnect the connector included in the circuit
(connector-B in the figure) and measure resistance
between terminals “A-1” and “B-1”.
If no continuity is indicated, that means that the
circuit is open between terminals “A-1” and “B-1”. If
continuity is indicated, there is an open circuit
between terminals “B-1” and “C-1” or an abnormality
in connector-B.
1. Check contact tension by inserting and removing just for once.

Downloaded from www.Manualslib.com manuals search engine 00-13 Precautions:
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.
a) If measurements were taken as shown in the
figure and results were as listed in the following,
it means that the circuit is open between
terminals “B-1” and “A-1”.
Voltage between
“C-1” and body ground: Approx. 5 V
“B-1” and body ground: Approx. 5 V
“A-1” and body ground: 0 V
b) Also, if measured values were as listed in the
following, it means that there is a resistance
(abnormality) of such level that corresponds to
the voltage drop in the circuit between terminals
“A-1” and “B-1”.
Voltage between
“C-1” and body ground: Approx. 5 V
“B-1” and body ground: Approx. 5 V
“A-1” and body ground: Approx. 3 VShort Circuit Check (Wire Harness to Ground)
1) Disconnect negative (–) cable at 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 (1), disconnect all connectors of
those parts.
Otherwise, diagnosis will be misled.

3) Measure resistance between terminal at one end of
circuit (“A-1” terminal in the 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.
4) Disconnect the connector included in circuit
(connector-B) and measure resistance between “A-
1” and body ground. If continuity is indicated, it
means that the circuit is shorted to the ground
between terminals “A-1” and “B-1”.
