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.

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.

cthere are some malfunctions, indicating light will indicate them. If exterior malfunctions are historical,
after they are removed, indicate will disappear.
done displayed or historical malfunction is only set up again by server. Inner malfunction or “impact
record” of safety airbag controller (KD4.1) could not be set up again, in this situation, it is necessary to
change safety airbag controller (KD4.1).
(3) micro controller, independent indicating light illuminates.
Microprocessor having obvious malfunction state could not work, so it could not control the work of indicat-
ing light. In this situation, indicating light will illuminate directly by applicable circuit without considering the
micro-processor, liking that shown in following:
zThe battery providing electricity for safety airbag controller (KD4.1) disables: indicating light illumi-
nates by the automatic light driving function.
zInner working voltage loses: indicating light illuminates usually.
zNew setup caused by the unsuccessful watchdog trigger: indicating light flashes
zMicro-processor does not work: indicating light illuminates usually
zInsert of connecter of safety airbag controller (KD4.1) is wrong: indicating light illuminates usually by
short circuit stick.
Take example to specify diagnostic step:
If finding indicating light of safety airbag illuminates usually, even if it extinguishes at last, you could check
by follow step. First is to check the part happening malfunction with diagnostic tool.
Then make by the checking step for corresponding position.
a. If scan result is inner malfunction or safety airbag has exploded, at this time, change the ECU directly.
b. Malfunction has been removed.
