6. Exhaust the air in steering system:
(a) Loosen the bleeding plug;
(b) Screw up the bleeding plug when there is no air bubble
exhausted from the pipeline.
Notice: take care not let the ethane pipe slide from the
bleeding plug, because the liquid is high in temperature
and pressure.
7. Check to see whether there is air bubble or turbidities
in the oil cup, and ensure the liquid level will not
exceed the max value when the engine stops,
Measure the liquid height under the condition of engine running,
then turn off the engine and measure the liquid height again.
In case any problem is found, repeat the approaches of (5) and
(6) in Power Steering Liquid Change. If the problem still
exists, repair the power steering oil pump.

steering oil pump with SST.
2. Loosen the belt pulley nuts;
Press the driving belt by hand to fix the belt pulley to immo-
bilize and loosen the belt pulley nut.
3. Adjust the driving belt tension after mounting the
power steering oil pump;

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 atON position
Put the ignition switch and SW1 at ONposition;
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

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 SystemBrief Introduction0

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 atON position;
Put the ignition switch of SW and SW1 atON 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

coil
