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.

Anti-stealing and door lock--Electronic anti-stealing system
Electronic anti-stealing system
Electronic anti-stealing system consists of anti-stealing controller, anti-stealing loop and transmitter. One
end of loop covers ignition locker core, the other end connects with anti-stealing controller, and the other end
of controller connects with engine ECU, at the same time, transmitter is assembled in key. Memory of
transmitter stores only mark (code) showing the legal identity of automobile owner, transmitter, anti-stealing
controller and electric injection ECU constitutes a multi-layer effective electronic anti-stealing system verified
by password.
If customer key loses, anti-stealing ECU is changed or engine ECU is changed, it is necessary to match
again in repairing station. When automobile leaves the factory, safety password is delivered directly to
owner for keeping with the type of secrecy. If it is necessary to make a new key, change anti-stealing
controller and make other operations, owner should bring the safety password with the automobile to repair
in repairing station. Repairing station should keep repairing (make new key, change anti-stealing controller
and so on) record for inquiring in future.
