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.

(4) Joint locking organization:
Lock the locking clasp of joint to fasten the connection of joint.
2. When the automobile front face is impacted, and generated force is bigger than the standard pre-set,
airbag will work automatically. The sensor in safety airbag controller will feel the impact, at the same
time, it will judge the generation of impact by inner arithmetic to make ignition electric current. Electric
current will flow in gas generator to make explosive function, then two gas generators in airbag at the
side of driver and passenger will make gas to increase quickly inner pressure of airbag and rush out
the trim cover of steering wheel and instrument panel. After airbag charging is closed, the gas ejects
from the gas outlet at the side or at the back of airbag.
II. Disassemble the connecting joint of lower helix cable and wiring harness of steer-
ing wheel.
1. Put your finger on sliding block.
2. Move the sliding block to release the clasp.
3. Pull out the male joint.

2. Inspection for indicating light of safety airbag
(1) When set the ignition switch at ON position, confirm whether the indicating light illuminates.
(2) After illuminating for five seconds, confirm whether indicating light extinguishes forever.
(3) If starting ignition switch for five seconds, indicating light does not extinguish (flash or illuminate for long
time), confirm the position of system malfunction with special diagnostic tool according to the flash
situation of indicating light.
3. System diagnosis
Safety airbag controller (KD4.1) will implement a series of cycle diagnostic testing to check whether the
function of airbag system has been prepared completely. This test will prevent restraint system from
exploding wrongly and insure the necessary explosion in impact. If finding any malfunction, safety airbag
controller (KD4.1) will store a applicable malfunction code and turn on indicating light to indicate a mal-
function state to be easy to maintain.
4. Malfunction judgment
(1) Malfunction category
System malfunction could be divided into three categories: power supply malfunction, subassembly
assembling malfunction and ECU inner malfunction.
a. Power supply malfunction
Normal working voltage of ECU is 9-18 V, related working voltage is 12 V. When automobile key is
turned to ACC gear, ECU connects power and begins to self-check, indicating light extinguishes
after illuminating for five seconds, this shows there is not any malfunction in ECU and exterior
subassembly, they could work normally. When automobile power voltage is less than 9V or higher
than 18V, ECU will self-check again. If self-checking could pass, ECU works normally, and indicat-
ing light extinguishes; if self-checking could not pass, it is necessary to self-check again, this self-
checking could be made six times, if indicating light illuminates all the time after six times, there is
some malfunction in power supply.
b. Assembling malfunction of airbag subassembly
Assembling malfunction of airbag subassembly is that malfunction which only needs to change or
repair airbag subassembly without needing to change ECU, including the situation that airbag
subassembly is not connected completely. If happening this malfunction when connecting power
supply, indicating light will flash N times at first, then it will illuminate all the time until malfunction is
removed. If happening impact in malfunction term, ECU could explode the channel of good part
and record every malfunction when exploding.
c. Inner malfunction of controller
Inner malfunction is the malfunction happening in ECU body, when happening this malfunction,
ECU could not explode airbag, and will record the impacting acceleration.
Note: common repairer could not repair this inner malfunction, if happening this malfunction,
it is necessary to change ECU.
(2) Malfunction state display
Malfunction treatment
1. Basic procedure of malfunction diagnosis
zAfter assembling new electronic control unit of safety airbag system, indicating light of safety airbag
system will extinguish forever after flashing for 5 seconds when ignition switch is at state of ON, this
shows airbag system works normally. At this time, the system does not need to repair, it is necessary
to make system diagnosis and repair when showing any situation except this.
zIf indicating light of safety airbag system does not illuminate when ignition switch is at the state of ON,
check the related circuits of indicating light, then operate it to make it enter working state.

Malfunction display of SRS could confirm originally by the flash of indicating light, detailed information
could be gained by malfunction diagnostic tool.
a. Safety airbag indicating light is driven by ECU, all malfunction displays are finished by ECU. After
working voltage is supplied for safety airbag controller (KD4.1) by battery, safety airbag controller
(KD4.1) illuminates indicating light to check SRS. To notify driver that there are some malfunctions
in system, indicating light will illuminate for long time after working voltage is supplied. If existing
SRS does not have any malfunction, indicating light will close after illuminating for five seconds
after ignition on. In original phase, safety airbag controller (KD4.1) does not prepare to check the
impact and stop the unfold until the wire of safety airbag controller (KD4.1) is reliable.
After ignition switch is turned to “ON” gear, the display type of indicating light when there is no any
malfunction in SRS is:
