Steering System Maintenance
Structure Introduction
The steering wheel has an airbag module which should only be inspected and repaired by a professional. The
steering column's upper section adopts a steel deformation and energy absorbing crumple structure which
ensures collision protection for the driver. The lower section uses a high precision sliding spline structure,
which can effectively eliminate structural interference caused by body deformation. The steering column angle
is adjustable, which can more easily adapt to the driver, and at the same time possesses reasonable reverse
efficiency to ensure the driver has a good feel for the road. Steering sys\
tem is as shown below:
Steering column assembly removal and
installation
1. Remove the airbag.
(a) Disconnect the battery's negative cable, and wait for
one minute before canceling the airbags function in
order to avoid unnecessary injury.
(b) To ensure steering column's proper installation, during
the entire removal process, the front tires must keep
straight.
(c) Remove the two hexagon screws and the airbag module.

2. Remove the steering wheel.
(a) Remove the lock nut Q32012 (M12×1.25) of steering
wheel with a M18 socket wrench in the counterclock-
wise direction.
(b) Grip the entire steering wheel and shake it several
times, and then to pull out the steering wheel upwards.
3. Remove the upper and lower trim cover of the combina-
tion switch.
4. Remove the left and right combination switch and the
ignition lock.
(a) Pull out the wire harness on the left and right
combination switch and the ignition lock.
(b) Remove the left and right combination switch and the
ignition lock.
5. Screw off the bolt 3404202-S08 connected the steering
column and steering propeller shaft with a M13 socket
wrench in the counterclockwise direction.
6. Screw off the two flange bolts Q1840820 (d2=22) which
are in the upper part of steering column connected
to instrument brace reinforcement with a M13 socket
wrench in the counterclockwise direction, and screw
off one flange bolt Q1840850 which is in the lower
part of steering column connected to instrument brace
reinforcement with a M10 socket wrench in the counter-
clockwise direction. Follow the column's upper axes
and pull out the steering column assembly.

4. Screw off the two bolts Q1840816 of the steering
gear protection plates installed on the subframe with
a M10 socket wrench, and remove the steering gear
protection plate.
5. First fasten four hexagon nuts 2904013-S08 with a
M18 socket wrench, then screw off the four hexagon
bolt gasket groups 3411013-S08 and 3411014-S08
installed on the subframe with a M14 socket wrench.
6. Remove and replace the steering tie rod ball assembly.
Fasten the hexagon nuts in the cotter pins with a M12 socket
wrench, then loosen the steering tie rod ball with a M19
socket wrench, and then finally pull out steering tie rod ball
assembly.
2. Unscrew the hexagon bolts for flange face Q32008

overall vehicle, disconnect the coupling nut of steering
pipeline and steering gear's high-low pressure oil
port with a M19 wrench. The removal of the steering
pipeline is then complete. While installing this area,
please ensure the two O-rings are in good condition,
and connect the high and low pressure pipeline and
steering gear low pressure oil port according to the
locations shown in the diagram. The tightening torque
of the two nuts is 46±2 N·m.

Steering pipeline removal and installation
1. Disconnect the hollow bolt which connects the high
pressure oil pipe and the power steering pump with a
M22 socket wrench. When installing, please take note
of the two seal gaskets and do not allow the oil pump
port to loosen. Each of the seal gaskets should be
positioned at either side of the high pressure oil ring.
Tightening torque for the hollow bolt is 30±4 N·m.

1. Configuration introduction
The GWFLORID comes in three configurations: comfort, luxury and elite. The wire harness has two types of
configurations: One is a non jam protection comfort model, which is a combination of both comfort and luxury
type, the other type is called elite. These two configurations are universally used in most of this manual. The
parts that are only available for the non jam protection comfort type have been marked in this manual, please
pay attention to these sections while performing maintenance.
2. Fuse box and power supply introduction
The fuse box located inside the left side of the dashboard is No. 1 Fuse Box, the other one inside the left side of
the engine compartment is No. 2 Fuse Box.
• 30 represents a power cord for normal power, which is from the battery positive fuse box-60 A.
• 30a represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 30b represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 15 represents a power cord for small capacity electronics. When the ignition switch is at the "ON" position,
power is supplied by relay IG.
• 15a represents a power cord for small capacity electronics. When the ignition switch is at the "ON"
position, power is directly supplied by ignition switch IG1.
• 15b represents a power cord for small capacity electronics. When the ignition switch is at the "ON"
position, power is directly supplied by ignition switch IG2.
• X represents a power cord for small capacity electronics. When the ignition switch is at the "ACC"
position, power is supplied by relay ACC.

Areas of importance in circuit maintenance
1. Before operating any electronic devices, and when tools or maintenance devices may easily make
contact with an uncovered electronic terminal, please make sure to turn the ignition switch to the LOCK
position, and then disconnect the battery's negative cable to avoid injury or vehicle damage. When the
ignition switch is on the ON position, please do not disconnect the battery's connecting wire or take out
the power's fuse, regardless if the engine is running or not.Otherwise it would seriously damage the
ECU and related microelectronic devices such as sensors.
2. When changing the fuse, please make sure that the new fuse possesses the proper current rating,
and is not above or below this rating.
3. When repairing the wire harnesses of the airbag and pretensioner, only specified contact points,
plugs, and wires are allowed to be used.
4. Before repairing the wire harness, make sure to eliminate any factor that might cause damage,
for example, the edge of a vehicle body part is too sharp, or the used electronics are damaged or
corroded.
5. Shielded wire should not be repaired, it must be replaced entirely once it is damaged.
6. Unless it is specified during the test, please do not use an analog multimeter to test the ECU and
sensor, instead use a high-impedance digital multimeter (internal resistance should be ≥10 kΩ) or a
vehicle multimeter for inspection.
7. When inspecting the connector with a digital multimeter, take the waterproof rubber cover off the
connector, and tightly insert the test pen along the connecting terminal. Don't use too much force, as
to avoid cracking the connector.
Circuit inspection steps
The principle of troubleshooting is to confirm the "possible cause". Once the possible cause is confirmed, the
components that need to be inspected are limited to the components that are related to the possible cause. The
confirmed possible cause should be based on theory and be supported by facts, but not just by intuition. If
one tries to solve the problem but does not adopt the proper troubleshooting steps, it may make the problem
worse. Then the possible cause not only can't be confirmed, but also maintenance can't be performed properly.
Troubleshooting should adhere to the four steps below:
1. Observe the symptoms carefully, inspect if there is anything else abnormal, and record it.
2. While confirming the possible causes, study the circuit diagram carefully, and regard it as a whole
system in order to understand the circuit. Thorough knowledge of switches, relays, and other
electronic components is obligatory for proper analysis.
3. Inspect and eliminate the problems one by one until the cause is found.
4. After the malfunction is fixed, make sure to check if the inspected system is working properly, and also
check if the maintenance may have caused any new problems.
