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.

(4) Connect conversion wiring harness of safety airbag on yel-
low joint of helix cable, then lead it out of automobile with
unfolding wiring harness (see following figure).
(5) Close all windows and doors, and assemble automobile
cover.
(6) Cut off the joint of wiring harness used for unfolding of safety
airbag assembly at the side of driver at the place apart from
the automobile, then connect it with two ends of battery
taken from automobile to make it explode (see following
figure).

Anti-stealing and door lock--Electric door lock control system
3. Check panel junction box assembly.
(a) Check 25A DOOR fuse.
(b) Check conformity relay.
(1) Disassemble F, G, H and I joint on instrument junction
box.
(2) Check the voltage and conduction of every terminal of
joint. (d) Check security function:
(1) When closing all doors, open the driver window to operate door control switch out of automobile.
(2) Take down the key, open driver door, then close the door and lock (not use key). In this situation
above, check that door could not open locker even if door control switch (handle operation) is
pressed to locker opening side out of automobile.
(3) Take down the key, close and use the key to lock driver door. In this situation above, check that
door could not open locker even if door control switch (handle operation) is pressed to locker
opening side out of automobile.
(4) Take down the key, close and use remote control key to lock driver door. In this situation above,
check that door could not open locker even if door control switch (handle operation) is pressed to
locker closing side out of automobile (only applicable for the automobile equipping with remote
control door locker control system).
Hint:
zIn following situation, check whether security has been canceled.
zIgnition switch is turned to ON.
zUse key operation to open the driver door locker.
zAfter door locker is pressed to opening side by hand, door control switch (handle
operation) is pressed to locker opening side.
zUse remote control locker control to open the door (only applicable for the automobile
equipping with remote control door locker control system).

Anti-stealing and door lock--Electronic anti-stealing system
Electronic anti-stealing system
Electronic anti-stealing system consists of anti-stealing controller, anti-stealing loop and transmitter. One
end of loop covers ignition locker core, the other end connects with anti-stealing controller, and the other end
of controller connects with engine ECU, at the same time, transmitter is assembled in key. Memory of
transmitter stores only mark (code) showing the legal identity of automobile owner, transmitter, anti-stealing
controller and electric injection ECU constitutes a multi-layer effective electronic anti-stealing system verified
by password.
If customer key loses, anti-stealing ECU is changed or engine ECU is changed, it is necessary to match
again in repairing station. When automobile leaves the factory, safety password is delivered directly to
owner for keeping with the type of secrecy. If it is necessary to make a new key, change anti-stealing
controller and make other operations, owner should bring the safety password with the automobile to repair
in repairing station. Repairing station should keep repairing (make new key, change anti-stealing controller
and so on) record for inquiring in future.
