rcuit Fault

Diagnosis

Diagnostic Procedure

Refer to the following procedure for the circuit
fault diagnosis:

1. Confirm Fault

To d o t he p r op e r r epai r, c onf ir m t he f au lt
symptoms described by the customer firstly.
Inspect the relevant component carefully to
confirm the fault symptoms and make record.
DO NOT disassemble the component before
confirmation of the fault scope and causes.

2. Read Wiring Diagram and Analyze Causes

Make a complete analysis and judgement on
the fault components from power supply to
grounding according to the sub-system wiring
diagram and determine the repair solution. If
it cannot be determined, please read the
system description in the “Description and
Operation” section in the repair manual to
understand the working principle. And inspect
other circuits that has common part with the
fault circuit, for example, the fuse, grounding,
switch, etc. Inspect the circuit not covered in
step 1. If other components in the common
circuit work properly, it means the fault exists
in its own circuit. Otherwise, the fuse or
grounding may have faults.

3. Inspect Circuits and Components

Always use the wiring diagram together with
repair manual and refer to the diagnostic
procedure for the relevant circuits or
components in the repair manual. For the
circuit with a control module, fully use
diagnostic tools to do the test. Effective
diagnosis should be a logical and reasonable
operation. Fully use the diagnostic
procedures in the repair manual and start the
inspection from the causes with most
possibility and the components with easiest
inspection way.

5. Confirm Circuit Working Condition

After repair, all functions should be reinspected
to confirm the fault repaired. For the fuse blown
fault, Inspect all the relevant circuits using this
fuse.

Diagnostic Tools

1. Voltmeter and Test Lamp

Use test lamp or voltmeter to inspect the
circuit status. Test lamp comprises a pair of
wiring harnesses and a 12 V bulb. When
inspecting, connect one wiring harness to the
ground and the other one to the certain
measurement point. If the bulb is lit, it means
the measurement point has power supply.

Warning: DO NOT use test lamp to inspect
the control module voltage. Otherwise it
could damage the interior circuit inside
the control module. Please use a voltmeter
with 10 MΩ or higher internal resistance
(for example, to test the ECM voltage).

Voltmeter has the same connection method
as the test lamp, but voltmeter can display the
voltage value of the circuit. Use a voltmeter
with high resistance to test the voltage. If the
circuit has poor connection, the voltmeter
may show the normal value, but the voltage
cannot drive the load successfully.

4. Repair Fault

Repair the fault. Refer to the wiring diagram
and the description for fault treatment in
repair manual. For example, the diagnostic
procedure for poor grounding and the wiring
harness connector treatment.

2. Self-powered Test Lamp and Ohmmeter

Use test lamp with own 12 V power supply or
ohmmeter to inspect the circuit for continuity.
Te st la mp c o mp ri se s a bu lb , b a tt e ry a nd a p air
of wiring harnesses. The bulb will be lit when
the two wiring harnesses are connected.
Before testing, disconnect the negative
battery cable and pull out the fuse of the
circuit. To test the circuit for continuity,
connect two wiring harnesses to the two
measurement points. If the bulb is lit, it means
the circuit is normal.

Warning: DO NOT use self-powered test
lamp to inspect the control module.
Otherwise, it could damage the interior
circuit inside the control module. Please
use a ohmmeter with 10 MΩ or higher
internal resistance.

Ohmmeter has the same usage method as
voltmeter, but ohmmeter can show the
resistance value. The lower resistance, the
better continuity.

3. Jumper Wire with Fuse

Use jumper wire to test a broken point for
open loop circuit (circuit open). The jumper
wire is a tool that should be in tandem with
the circuit.

Warning: To protect the circuit to be
inspected, DO NOT use the fuse higher
than the rated capacity of circuit to
inspect relevant circuits. DO NOT use the
jumper wire as the input or output signal
when a control module such as ECM or
TCM is in the circuit. Otherwise it could
damage the circuit interior inside the
control module.

or voltmeter, connect the negative of
testing tools to battery negative.

2Connect the other wiring harness of the

test lamp or the positive probe of the
voltmeter to the test position.

3If a voltmeter is used and voltage display

lower 1 V above compared to the rated
value, it means a circuit fault. It means a
circuit fault if a test lamp is used and lamp
is not lit.

2. Power Testing

3. Short Circuit Testing

1Disconnect the negative battery cable.

2Connect one wiring harness of the self-

powered test lamp or the probe of the
ohmmeter to the test component. If using
ohmmeter, please connect the two
probes each other and use reset button
to adjust the ohmmeter to zero.

3Connect the other wiring harness of the

test lamp or probe of the ohmmeter to the
other side of the test load.

4If the bulb is lit, it means the circuit is

normal. If an ohmmeter is used and the
resistance value is very low or close to 0
Ω, it means the component has good
continuity.

1Disconnect negative battery cable.

2Connect one wiring harness of the self-

powered test lamp or one probe of the
ohmmeter to the output terminal of the
fuse.

3Connect the other wiring harness of the

test lamp or other probe of the ohmmeter
to the grounding.

4Disconnect all the electrical loads to the

fuse.

CAUTION: If not disconnecting all the
electrical loads to the fuse, when testing
the low resistance circuit like lights, the
ohmmeter will always display the low
value. This will cause wrong judgement.

5Do the careful inspection from the place

closest to the fuse.

6If the bulb is lit or ohmmeter has value

display less than 5 Ω, it means the short
circuit to the ground.

voltmeter to one end of the circuit close to
the battery (connector or switch side).

2Connect the negative probe to the other

end of the circuit (the other side of
connector or switch).

3Switch on or off to make the circuit work.

4The voltmeter will display the voltage

difference between the two test points.

5If the voltage difference is more than 0.1

V (less than 50 mV for 5 V voltage
circuit), it means a circuit fault. Inspect for
loose, oxidized or corrosive circuit.

It can simulate each ohm-type sensor signal,
like coolant temperature sensor, air intake
temperature sensor and the like. And help
make quick judgement on the performance of
the component.
