airbag GREAT WALL FLORID 2008 Service Manual

Downloaded from www.Manualslib.com manuals search engine PREFACE
GWFLORID will build 1.3L (GW413EF, GW4G13) or 1.5L (GW4G15) gasoline engines, in which the
GW4G13 and GW4G15 engines will both incorporate the newest VVT technology which meets the Euro IV
emission standards. GWFLORID features McPherson technology on its chassis system. With an ultra light
body made from structural steel and high-intensity front and rear fender impact beams as well as a collision
impact absorption system, it is able to maintain the cab's integrity and safety to greater extent. We wrote this
maintenance manual in order to meet the demand of Great Wall after-sales service technicians. This manual
mainly introduces the areas of importance in regard to maintenance and care, and removal and installation of
each system's assembly and maintenance technical parameters.
To reduce the possibility of injury or property damage, read and follow t\
he instructions carefully:
This manual is provided by the Great Wall Motor Co., Ltd, and is written for the technician use. Any
maintenance or repair without proper prior training and tools or devices may result in personal injury of the
person performing the maintenance or others in the vicinity. It is also possible that damage to the vehicle will
occur or will lead to mechanical failure during normal operation.
Correct vehicle maintenance and repair is essential for the safety of the person performing regular
maintenance as well as the vehicle itself. If there is any component that needs to be replaced, use a
component with the same serial number or a serial number specified by the Great Wall Motor Co., Ltd. Never
use any part that has not been authorized by the Great Wall Motor Co., Ltd.
Any maintenance procedure introduced in this manual is effective for maintenance and repair. Some of
these procedures need specially designed tools.
Therefore, before using any vehicle part following any maintenance procedure or working with a tool
that has not been authorized by the Great Wall Motor Co., Ltd, check to make sure that none of the above
will endanger the safety of the person performing the work or the correc\
t operation of the vehicle.
This manual includes multiple "Warnings" and "Cautions," which should be strictly followed, so as to
reduce the possibility of injury during maintenance or repair. Improper maintenance or repair of the vehicle
may cause potential safety hazards. These "Warnings" and "Cautions" are not exhaustive. It is impossible for
the Great Wall Motor Co., Ltd, to warn against all the potential dangers caused by not properly following the
instructions.
Please read carefully the "Areas of Importance" before carrying out any maintenance or repair on the
airbag system's components or its surrounding electrical components. Action contrary to any of the "Areas of
Importance" may lead to the deployment of the airbag, resulting in injur\
y or unnecessary repair of the airbag.
To avoid accidental deployment of the airbag and its resulting injury, we suggest repairing the airbag
system before other vehicle systems if the airbag and the other vehicle \
systems both need repairing.
We have received generous support and help from many professional technicians during the preparation
of this manual. We would like to express our heartfelt gratitude to all of them.
Although we have tried our best to write this manual well, we do not guarantee that the entire content
in this manual is absolutely correct. Users may not make any legal claim against the Great Wall Motor Co.,
Ltd. in regards to this manual. Any loss caused by using this manual is not our responsibility. Because of
the writer's limited experience, there are likely mistakes in this manual, therefore we welcome any user
comments, suggestions, and corrections.
Great Wall Motor Co., Ltd. reserves the final right of explanation.

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.

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.
