d. Loosen the connectors of all safety airbag system units,
e. Check whether the connector between electronic control unit of safety airbag system and the
circuit between connector of safety belt pre-tension have following situations:
zEarth
zShort connection with power supply
zOpen circuit
f. Are the wiring harnesses above normal?
Normal: malfunction diagnosis ends
Abnormal: change related wiring harness.
8. Malfunction of impact output
Malfunction of safety airbag assembly at the side of passenger (resistance is too big
or too small, short circuit, grounding and so on)
Resting conditionWarning
zIf the treatment is wrong, safety airbag assembly and pre-tension safety belt might be
triggered to unfold and tighten to make heavy human hurt, so, before the treatment, it
is necessary to read repairing warnings carefully.
Refer to repairing warning of safety airbag system.
Possible reason
zConnector between impact output circuit and electronic control unit of safety airbag sys-
tem has malfunction.
zConnector between safety airbag system unit and grounding position has malfunction.
zThe circuit between impact output circuit and electronic control unit of safety airbag
system happens open circuit or short circuit.
zCircuit between safety airbag system unit and grounding position happens open circuit
or short circuit.
zSafety airbag system unit has malfunction.
(1) Check whether this airbag controller has impact output function
a. Set ignition switch at LOCK position
b. Loosen the cathode cable of battery and keep this state for one minute at least
(2) Check whether the connection of impact output connector is good,
(3) Check whether the impact output connecting wire is earth or is short connecting with other wires,
(4) Check whether impact output connecting wire is open circuit,
(5) Check whether the central control door lock control system or electric injection control system of
engine has been changed,
Note: If repairing it by the steps above and requirements, indicating light or diagnostic tool
could display the mistakes before repairing all the time, please do not change it by
yourself, you should contact with the manufacturer as soon as possible avoid wrong
explosion or no explosion when using airbag.

Diagnosis of impacted automobile
No matter whether the safety airbag has been unfolded, the inspection and maintenance for impacted auto-
mobile should be made by following sequence.
1. Check the ECU diagnostic signal.
(1) Connect the diagnostic joint of diagnostic tool,
(2) Use diagnostic tool to read the diagnostic result.
2. Repair sequence
Note: For the impact, when power supply of battery is lack, diagnostic tool could not communicate
with ECU, at this time, it is necessary to check and maintain the wiring harness of panel or use
exterior power supply.
(1) When safety airbag has been unfolded,
Following parts should be changed with new ones
a. Safety airbag assembly at the side of passenger
b. ECU
c. Safety airbag assembly at the side of driver
d. Pre-tension safety belt at the side of driver and passenger
Check the following parts, if they are abnormal, change them with new ones
a. Helix cable
b. Steering wheel, steering column, combination switch
Assembling state for steering wheel of safety airbag assembly at the side of driver
a. Check whether there is any abnormal noise in steering wheel, its action is flexible and clearance is

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.
