3. Press the contact point to the male terminal down by holding

a screwdriver [1.4 mm (0.06 inch) width] as shown in the
figure. Lightly squeeze the outer edge so the flats are
parallel with the bottom.

INJECTOR CONNECTOR

1. Remove the waterproof cap.

2. Insert the tip of a screwdriver [1.4 mm (0.06 inch) width] into

the connector as shown in the figure, press in the terminal
lance, and pull out the terminal.

CAUTION

Make sure the lance is pressed in before the terminal is
inserted into the connector.

HOW TO DIAGNOSE

HOW TO DIAGNOSE

M1001004300086

The most important point in troubleshooting is to
determine "Probable Cause." Once the probable
causes are determined, parts to be checked can be
limited to those associated with such probable
causes. The determination of the probable causes
must be based on a theory and be supported by facts
and must not be based on intuition only.

TROUBLESHOOTING STEPS

M1001004400049

If an attempt is made to solve a problem without going through correct steps for troubleshooting, the symp-
toms could become more complicated, resulting in failure to determine the causes correctly and making
incorrect repairs. The four steps below should be followed in troubleshooting.

Probable Causes and Determination
of Faulty Parts

2 Determination of Probable Causes

4 Repair and Confirmation

Observe the symptom carefully. Check if there are also
other problems.

In determining the probable causes, it is necessary to
study the wiring diagram to understand the circuit as a
system. Knowledge of switches, relays and other parts is
necessary for accurate analysis. The causes of similar
problems in the past must be taken into account.

Troubleshooting is carried out by making step-by-step
checks until the cause is found.

After the problems are corrected, be sure to check that the
system operates correctly. Also check that new problems
have not been caused by the repair.

INFORMATION FOR DIAGNOSIS

M1001004500132

This manual contains the harness diagrams as well as the individual circuit drawings, operational explana-
tions, and troubleshooting hints for each component. The information is presented in the following manner:
1. Connector diagrams show the connector

positions, etc., on the actual vehicle as well as the
harness path.

2. Circuit diagrams show the configuration of the

circuit with all switches in their normal positions.

3. Operational explanations include circuit drawings

of current flow when the switch is operated and
how the component reacts.

4. Troubleshooting hints include numerous

examples of problems which might occur, traced
backward in a common-sense manner to the
origin of the trouble. Problems whose origins may
not be found in this manner are pursued through
the various system circuits.

NOTE: Components of MFI, ETACS, etc. with ECU do not include 3 and 4 above. For this information, refer
to a relevant group which includes details of these components.

INSPECTION

M1001004600139

1. Sight and sound checks

Check relay operation, blower motor rotation, light
illumination, etc. Listen for a "click" when some relay covers
are pushed down.

2. Simple checks

For example, if a headlight does not come on and a faulty
fuse or poor grounding is suspected, replace the fuse with a
new one. Or use a jumper wire to ground the light to the
body. Determine which part(s) is/are responsible for the
problem.

3. Checking with instruments

Use an appropriate instrument in an adequate range and
read the indication correctly.

INSPECTION INSTRUMENTS

M1001004700040

For inspection, use the following instruments:

CAUTION

Never use a test light for checking ECU-related circuits or
ECUs.
1. Test light

A test light consists of a 12V bulb and lead wires. It is used
to check voltages or short circuits.

2. Self-powered test light

A self-powered test light consists of a bulb, battery and lead
wires connected in series. It is used to check continuity or
grounding.

CAUTION

Never use a jumper wire to connect a power supply
directly to a load.
3. Jumper wire

A jumper wire is used to close an open circuit.

4. Voltmeter

A voltmeter is used to measure the circuit voltage. Normally,
the positive (red lead) probe is applied to the point of voltage
measurement and the negative (black lead) probe to the
body ground. Use a digital voltmeter to check for voltage
drop before or after a component.
