Power Steering (On-Vehicle Inspection)
Change of power steering liquid
1. Tear down the oil-returning hose from the oil cup to
drain the liquid into the container;
2. Run the engine in the idle status, and rotate the
steering wheel toward the max rotating angle for
several times in right or left direction while draining the
liquid, until the oil in steering liquid is drained up.
3. Turn off the engine.
4. Connect the oil-returning pipe and inject the new
power steering liquid in the liquid tank;
Hydraulic oil type: No.8 Liquid drive oil (Q/SH003.01.012-88)
5. Start the engine, and make it running in the idle status.
Rotate the steering wheel to the max rotating angle repeatedly
several times, meanwhile, supplement new power steering
liquid in the liquid tank until there is no foam or turbidities in
the liquid tank, and the oil indicating lamp reaches the marked
range when the engine is turned off.
6. Tighten the liquid tank cover
7. Exhaust the air in the power steering system;
Ai-r bleeding in power steering system
1. Check the liquid level height in the liquid tank
Check the liquid level and, if needed, supplement the liquid.
2. Start the engine in the idle status and rotate the
steering wheel repeatedly to the max rotating angle
several times.
3. Turn off the engine and connect the ethane pipe and
bleeding plug.
4. Start the engine and rotate the steering wheel
repeatedly to the max rotating angle several times.
5. Locate the steering wheel at the intermediate position.

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.

Inspection on Common Trouble
Failure Judgment Methods
No backup radar display (no
system start notification when
the reverse gear is engaged)Check whether the plugging elements of power supply
of back up radar control box are in well connection as
shown in drawing H in next page.(when the reverse
gear is engaged, touch the detector, if there is vibration,
which shows the detector is powered.
Check whether the wire harness of inner mirror in
electric room and that on the top of body are in well
connection as shown in the drawing A in next page
Check whether the wire harness of back up radar
control box is well connected with that of chassis
and that on the top of body.
Rotate the vehicle key to the ACC position and
engage the reverse gear, then measure to see whether
the back up power supply reaches to 12 V with the
multi-meter of 50 V of voltage, refer to the
red
and black
positions shown in the drawing in next
page.
If the voltage reaches 12 V, change the backup
radar control box in trial firstly, then the inner
mirror in electric room, finally change the roof
wire harness and the chassis.
No backup radar display (but
there is start notification when
the reverse gear is engaged)
remark: such trouble occur
under the blocking condition.Check whether the power supply of back up radar
is well located, see the red and position in the
drawing of next page.
Check and align the plugging element.Poor properties of ultrasonic wave
Change the ultrasonic detector heads.
Continuous back up radar red
lamp alarming (remark: there
is no obstacle within 0.5 m away
from the detector head)Check whether the detectors in the two circuit of
back up radar control box is well plugged, see the
marked positions F, G in the drawing of next page.
Check and well connect those plugging elements
Poor connection of the left/right ultrasonic detector head
Poor performance of back up radar control box.Check and well connect those plugging elements
Change the ultrasonic detector head
Change the back up radar control box.

2. When the body height varies or the stand by tire is opened, make a new inspection for the rear stand by
tire to ensure the backup radar in normal operation.

Gearbox
Three-grade maintenance for gearbox
1. Grade I maintenance for gear box
Grade I maintenance: Check the lubricant level to see whether the lubricant level is in alignment with the lower edge of oil
filler; if the lubricant is lower than the oil filler lower edge, add the lubricant; or the insufficient lubricant will lead to the poor
lubrication or burn-out of bearing and teeth; while the over-high lubricant will cause the overheating and oil leakage.
2. Grade II maintenance for gear box
Grade II maintenance: The gear box of a new vehicle should be maintained by exchanging the lubricant during the
first grade II maintenance and should be washed with kerosene; and the lubricant quality should be checked in the
grade II maintenance in later time, if the lubricant is diluted, gumming or over-dirty, it should be changed.
3. Grade III maintenance
The gearbox should be disassembled for inspection, washing and oil change.
Notice: As the new vehicle is in the running-in status, the gearbox should be maintained by exchanging lubricant
after the vehicle covers 1500 km,
