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.

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:

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.
