2008 GEELY FC airbag off

Supplemental restraint system--Note
Note:
zWhen making repair, please make malfunction diagnosis by the flash light and malfunction diagnosing device
according with the method regulated in this operation manual at first, at the same time, it is necessary to check
whether there is any malfunction code before disassembling battery wire.
zForbid disassembling or repairing at any non-appointment repair station
zDo not assemble any safety lever or bumper at the front of automobile, this will influence the performance of this
airbag.
zPeople for repairing, disassembling and assembling should be trained specially.
zWhen disassembling steering wheel assembly, it is necessary to make steering wheel right, only this could disas-
semble steering wheel assembly and make helix cable locate correct position, or it will damage helix cable assembly.
zECU matches with the technical parameter of electric system, forbid using the SRS parts of other automobiles, at
the same time, it is necessary to use new product to replace any part.
zWhen repairing automobile (especially electric welding), it is necessary to close key switch, and it is best to cut off
the anode of battery.
zAfter unfolding airbag, safety airbag assembly and helix cable assembly should be changed completely.
zWhen disassembling or carrying airbag assembly, trim cover should face the upside; safety airbag assembly
could not superpose directly to avoid make wrong explosion and make any accident.
zThe inner malfunction of controller (ECU) could not repair, if it happens any malfunction, change it.
zSafety airbag assembly should be stored in the environment whose temperature is lower than 40C, relative humid-
ity is lower than 75% and is apart from electromagnetic interruption.
zForbid disassembling the airbag assembly and gas generator in it.
zForbid connect AC or DC with over 20V with ECU to avoid damage.

Note
Warning:
zThis product is the SRS (supplemental restraint system) equipped by JILI “YUANJIN vision” type automobile, when
the automobile frontal face is impacted heavily, this product could reduce the possible hurt for driver and passen-
ger at the front seat, but this product could not replace the safety belt. For SRS is supplemental restraint safety
system, the driver should tie safety belt. This product is single-point electronic dual-airbag system whose charac-
teristic is that all sensors and control circuits are assembled in control box and gas maker is protechny. At the
same time, this product accords with the enterprise standard “Automobile safety airbag equipment” (Q/JL001—
2001) to product.
zIn repairing process, if it does not accord with correct operation sequence to operate, SRS might happen the
accidental explosion to make heavy accident. If repair does not accord with correct procedure, even if repair does
not incur accident, SRS might disable when automobile happens accident, for example, it could not explode by
the requirement. So, when making repair (including disassembling, assembling, checking or changing any part),
it is necessary to operate by correct sequence regulated by repair manual.
zIt is necessary to confirm following works before repairing: 1. Put the ignition switch at “OFF” state. 2. Disconnect
the cathode connection of battery, and make repair after waiting for 60s. In addition, disassembled cathode
should be twisted by insulating tape to insulate. (Capacitor in ECU could keep some electric power after battery
is cut off to unfold safety airbag in some time. So, when making maintenance, if it does not wait for some time
before operating, it might incur heavy hurt accident for wrong expansion of safety airbag.)
zDo not put the parts of SRS directly under the insulation of hot air or flame.

Scrap treatment for safety airbag
Hint:
zWhen scraping a automobile with SRS or disposing safety airbag module, it is necessary to explode the airbag by
following steps at first.
zIf there is any abnormal phenomenon when exploding airbag, please contact with our service store or automobile
factory in time.
Note:
z Forbid exploding the safety airbag module that does not explode by yourself.

zWhen exploding the airbag, it will make much big explosive sound, so it is necessary to operate this out of the
automobile, please do not make this operation influence the life of near habitants to avoid their complaints.

zWhen exploding the airbag, use the battery as power supply whose voltage is (12±1)V.
zWhen exploding the airbag, operator should be apart from the exploded module and he should confirm there is
not anyone in the scope of 10m at least.

z When disposing the exploded airbag module, it is necessary to wear glove and safety glass.

zWhen airbag is exploded, the temperature of airbag module is too high, and a lot of gas with peculiar smell will
be produced, so do not make any treatment for exploded airbag in 30 minutes after exploding it.
zPlease wash your hands with water after finishing those operations above.
zDo not sprinkle water on exploded airbag module.
zWhen scraping a automobile, the safety airbag module assembled on automobile should be exploded.
I. Scrap the safety airbag module on automobile
1. Treatment before exploding:
(1) Park the automobile on flat place.
(2) Disassemble the cathode and anode of battery and disassemble the battery from automobile.
Note: do not work until disassembling the cathode and anode of battery for 60 seconds.
(3) Safety airbag assembly should be unfolded by following sequence.
2. Safety airbag assembly at the side of driver
(1) Disassemble three screws and lower cover of combination switch.
(2) Disassemble the lower end of helix cable and the joint connecting with panel wiring harness.
(3) Connect the conversion wiring harness of safety airbag with one wiring harness with over 10 m used
for unfolding, and the connecting part should be twisted with insulation adhesive tape to insulate and
prevent from wrong unfolding for static.
Note:take down the joint of helix cable from panel wiring harness, the joint of helix cable
will be short circuit automatically, this will prevent from exploding the safety airbag
assembly at the side of driver for static to make heavy accident.
