Faults Features Causes Solutions
7. Oil deterioration remove the fault
6. Check and clean the transmission oil
radiator
7. Check if the oil for dual-clutch
transmission (oil quantity and quality)
meets the requirement
8. Check if the oil return pressure of the
torque converter is too high, whether the
oil temperature raises rapidly due to too
large fluid resistance in the oil return
system leads to rapid rising of oil
temperature
9. Check the oil thermometer, oil
temperature sensor for accuracy
Insufficient steering
torque
Insufficient flow due to wear of
steering pump
Changed pressure of safety
valve
Serious inner leakage in steering
pump
Check or replace the steering pump
Adjust the pressure
Overhaul or replace
Insufficient foot braking
force
1. Oil leakage in brake master
pump or slave cylinder
2. Air in the brake hydraulic
pipeline
3. Low pressure of
compressed air
4. Damaged booster leather
cup
5. Oil leakage from wheel rim
to brake pad
6. Extremely worn brake pad
1、 Replace the leather cup or
rectangular seal ring
2、 Bleed the air
3、 Check the control valve, air reservoir
and pipeline of air compressor for sealing
performance
4、 Replace the leather cup
5、 Check or replace the hub oil seal
6、 Replace the brake pad
Gear engagement
failure after foot brake
1. The limit screw of air brake
valve pedal is adjusted
improperly, air brake valve fails to
return to the original position
fully, and transmission pressure
gauge does not work
2. The air brake valve position
gets stuck, without air return after
brake release
3. Inner leakage in pipeline or
oil cylinder
4. No compressed air gets into
the gearshift control valve
1. Readjust the limit screw of the pedal
so that the air brake valve can return to
the original position fully
2. Clean and overhaul the piston
3. Remove the brake valve rod for
overhaul
4. Check the emergency brake valve
