How to make systematic inspection
The inspection order is a simple troubleshooting approach, which is used to check and diagnose the failure on vehicle
when there is part (wiring and plugging elements excluded) failure in the systematic operation or presupposed
system.
Following items should be considered firstly when checking the failure.

wiring failure

open circuit or short circuit of electric wiring

failure in plugging element connection or terminal connection

failure of fuse or maxi-fuse
Notice:
1. The inspection is conducted on vehicle when the system is in operation, therefore, security should be
taken into account when checking.
2. Care should be paid not to make short circuit in the system under the condition that the accumulator is
directly connected, and the applicable voltage should be selected correctly.
Voltage inspection
(a) Verify the voltage situation at the inspection spots.
For example:

Put the ignition switch at
ON
position

Put the ignition switch and SW1 at
ON
position;

Put the ignition switch of SW, SW1 and the relay at

ON
position (SW2 at
OFF
position)
(b) Connect the cathode lead (-) to the normal grounding
place or the cathode terminal of accumulator with the
voltmeter; while connecting the positive lead (+) to the
plugging element or part terminal. Such inspection can
be conducted with the test bubble instead of voltmeter.
Inspection on Conductance and Resistance
(a) Disconnect the terminal or wire of accumulator to guar-
antee there is no voltage between the inspection sports.
(b) Connect the two measuring leads of ohmn meter with the
inspection spots.ohmn meter

Brief Introduction

BE-5
If there is diode in the circuit, connect the two leads in reverse
polar and make another inspection. When the cathode lead (-)
is connected with the positive (+) side of diode, and the
positive (+) lead should be connected with the cathode (-) lead
of diode, the diode should conduct, while the two leads
connected to the reverse polar, the diode should not contact.
Remark: the specification may be not same due to different
testing meter types; therefore, the application instruction for
testing meter should be referred before the inspection.
Check the light emitting diode (LED) according to the same
approach for diode inspection.
Remark:
The testing meter should be used the one with 3V voltage or the
one has larger resistance than that in circuit.
If no suitable testing meter is applied, the voltage of accumu-
lator may be added to check the LED to see whether it is
lighted.
(c) Use the voltage or ohmn meter with high-impedance
(min voltage of 10 KV) to diagnose the failure in electric
circuit. Body Electric System

Check to see whether there is short circuit
(a) Tear down the burned fuse and remove all loads from
the fuse.
(b) Connect the testing bubble at the fuse position;
(c) Verify the situation of testing bubble position:
For example:

Put the ignition switch of SW at
ON
position;

Put the ignition switch of SW and SW1 at
ON
position;

Put the ignition switch of SW, SW1 and Relay at

ON
position (which connects with the relay), and put
SW2 at
OFF
) position (or disconnect the SW2).
(d) Disconnect or re-connect the plugging elements when
observing the testing bubble. In case the testing bubble
keeps lighting, which shows there is short circuit between
the plugging elements; if the testing bubble extinguishes,
there is short circuit between the plugging elements.
(e) Shake the trouble wire alongside the body to locate the
SW2 electromagnetic
coil

c. The inaccuracy display of tachometer is usually caused by the interior failures of tachometer, in such situation,
change the combination directly. As for the good-bad shift or out-operation of tachometer, the failures can be judged
according to the following approaches:
1) Start the vehicle, then check the voltage of signal input of tachometer (wire harness with multi-meter, the
voltage should be 6 V or so.
2) In case there is no signal voltage, check the power supply system of the whole vehicle to remove the failures
in circuit.
3) The plugs of wire harness is only allowed to be inserted in the combination instruments under the condition
that the signal voltage is normal, and the instrument is in normal operation.
4) Where the instrument is in abnormal operation, such trouble is caused by the failure of combination
instruments, in such case, change the combination instrument directly.
d. Troubles of fuel gauge and water thermometer
1) In case the instrument indicator points to the large number after it is powered, disconnect the sensor from the
plugging elements of wire harness before judging such kinds of troubles, if the indicator is still at large number,
it can be make a judgment that the trouble is caused by the interior failure of instrument, in such case, change
the combination instrument directly; if the indicator returns to the small number, according to which it can be
judged that the trouble is caused by the sensor failure, therefore, change the sensor directly.
2) where the instrument indicator stands still, such trouble may be caused by three causes probably, interior failure
of sensor, plugging elements of wire harness or interior failure of instrument; the inspection may be conducted
according to the following approaches: disconnect the plugging elements of wire harness from that of sensor,
grounding the wire at the sensor end; in such condition, the indicator should move upwardly to the largest
number; if such phenomena occurs, it can show the trouble is caused by the interior failure of sensor, in such
case, change the sensor directly; if the instrument indicator is still immobilized after it is powered, it can be
judged that the trouble is caused by the interior failure of instrument under the condition that the wire harness
and plugging elements are normal, in such case, change the combination instrument directly.
