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.
Supplemental restraint system
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.

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
normal.
b. Check whether the joint of wiring harness is damaged or terminal is distorted.

(3) Fix the module on wheel.
a. Assemble two bolts with gasket on two assembling holes
of safety airbag module at the side of driver.
Size of bolt: L 35.0 mm
M 6.0 mm
Note:tighten the bolts with hand until they could
not be turned in. But they could not be
screwed too tightly.
b. Use maintenance electric wire used for automobile to
fix safety airbag module at the side of driver on wheel.
Section area of nude wire part of wiring harness is more
than 2 mm
2. If the wiring harness is too thin, it might
break for the shake when airbag explodes. This is very
dangerous.
c. Use three wiring harnesses, and the wiring harness
should twist the bolts at the two sides of airbag assem-
bly twice at least. Tighten the wiring harness twisted on
fixed bolts to avoid them loosen, if wiring harness loosen,
they might incur airbag assemble loosens for shake
when airbag explodes. This is very dangerous.
d. Place the airbag module upwards, and bind the con-
necting bolts at the two sides of airbag module in wheel
hub bolt holes of wheel. Adjust the fixed position of airbag
module to make the joint hang in the wheel hub hole of
wheel. Wiring harness should be tightened. The metal
surface of airbag assembly must face the downside to
prevent wiring harness from breaking for airbag
explosion, explosive force will throw airbag to air to hurt
human or surrounding things. Airbag explosion will leave
track for surrounding things, so used wheel should be
scraped.
(4) Place wheel on flat ground, and connect the one end of
wiring harness used for unfolding with airbag short wiring
harness, and connect the other end with short circuit.

2. If the wiring harness is too thin, it might
break for the shake when airbag explodes. This is very
dangerous.
c. Use four wiring harnesses, and the wiring harness should
twist the fixed bolts and small bracket of airbag assem-
bly twice at least. Tighten the wiring harness twisted to
avoid them loosen, if wiring harness loosen, they might
incur airbag assembly loosens for shake when airbag
explodes. This is very dangerous.
d. Place the airbag module upwards, and bind the wiring
harnesses at the two sides of airbag module in wheel
tightly. After twisting the tyre twice with the wiring har-
ness twisted on middle small bracket, bind it on tyre.
After twisting the tyre twice with the wiring harness
twisted on left and right small bracket, bind it on tyre.
Adjust the fixed position of airbag module to make the
joint hang in the wheel hub hole of wheel. Then fix the
wiring harness getting through the center of left and right
small bracket on tyre to prevent the module from shak-
ing left and right, and the wiring harness twisted on bolts
of small bracket is fixed on tyre to prevent airbag mod-
ule from shaking front and back.
(4) Place the wheel on flat ground, and connect one end of
wiring harness used for unfolding with airbag short wiring
harness, and connect the other end with short circuit. The
terminal end of unfolding wiring harness is 10m apart from
wheel of fixed airbag at least.
