d. Loosen the connectors of all safety airbag system units,
e. Check whether the connector between electronic control unit of safety airbag system and the
circuit between connector of safety belt pre-tension have following situations:
zEarth
zShort connection with power supply
zOpen circuit
f. Are the wiring harnesses above normal?
Normal: malfunction diagnosis ends
Abnormal: change related wiring harness.
8. Malfunction of impact output
Malfunction of safety airbag assembly at the side of passenger (resistance is too big
or too small, short circuit, grounding and so on)
Resting conditionWarning
zIf the treatment is wrong, safety airbag assembly and pre-tension safety belt might be
triggered to unfold and tighten to make heavy human hurt, so, before the treatment, it
is necessary to read repairing warnings carefully.
Refer to repairing warning of safety airbag system.
Possible reason
zConnector between impact output circuit and electronic control unit of safety airbag sys-
tem has malfunction.
zConnector between safety airbag system unit and grounding position has malfunction.
zThe circuit between impact output circuit and electronic control unit of safety airbag
system happens open circuit or short circuit.
zCircuit between safety airbag system unit and grounding position happens open circuit
or short circuit.
zSafety airbag system unit has malfunction.
(1) Check whether this airbag controller has impact output function
a. Set ignition switch at LOCK position
b. Loosen the cathode cable of battery and keep this state for one minute at least
(2) Check whether the connection of impact output connector is good,
(3) Check whether the impact output connecting wire is earth or is short connecting with other wires,
(4) Check whether impact output connecting wire is open circuit,
(5) Check whether the central control door lock control system or electric injection control system of
engine has been changed,
Note: If repairing it by the steps above and requirements, indicating light or diagnostic tool
could display the mistakes before repairing all the time, please do not change it by
yourself, you should contact with the manufacturer as soon as possible avoid wrong
explosion or no explosion when using airbag.

Vehicle inspection
1. inspect speed counter
(1) Use speedometer tester to inspect allowed error of speedometer and action of speedometer
Reference: Km/h
speed indicated by speedometer actual speed
20km/h17-23km/h
40km/h35-40km/h
60km/h55-60km/h
80km/h75-80km/h

140km/h133-140km/h
160km/h152-160km/h
Notes: tyre wear or tyre pressure too high or too low will increase error.
(2) Inspect speedometer needle offset
Reference: below 0.5km/h

Panel/combination instrument--combination instrument
2. Inspect output signal of vehicle speed.
(1) When vehicle run at 10km/h, inspect voltage between ter-
minal10 and terminal A1 of combination instrument assembly.
Standards: the voltage pulsates repeatedly between
0V to 5V for thirteen times.
Notes: Inspect the ignition switch “on” connects the
joint
3. Inspect speed gauge
(1) Connect a test tachometer. then startup the engine.
Notes:
zTachometer terminals polarity connects oppositely will damage interior transistors and
LEDs.
zWhen move or disassemble tachometer. do not drop on the ground or knock the surface.
(2) Compare indicted value test tachometer and combination instrument tachometer.
Standard indicted value (rmp) permitted values (rpm)
700 630-770
1,000 (900-1,100)
2,000 (1,850-2,250)

(1) Disassemble the joint of fuel meter
(2) Turn ignition switch to ON, inspect indictor position of fuel guage.
Indictor position: F
(3) Connect short terminal1 and terminal2 of wiring harness sides. Turn ignition switch to ON, inspect
indictor position of fuel guage.
Indictor position: F
5. Inspect low fuel level indictor 4. Inspect fuel gauge
The fuel gauge has the function of sensor detection (that is
failure treatment of oil level tachometer)that is when fuel gauge
indictor is at E position, if low oil level warning light doesn”t
light, first should judge whether there have open-loop trouble of
fuel sensor or wiring harness. When sensor fails, fuel indictor
should stop at current position. But if failing time is over 20
seconds, the indictor will return to E position quickly, the in-
strument will at wire break detection. If the normal situation of
detection panel is over 20 seconds, indicator will return to normal.

indictor is at E line, the indictor light lights.
6. Inspect generator water thermometer .
(1) Disassemble joint of generator water thermometer
(2) Turn ignition switch to ON, inspect indictor position of gen-
erator water thermometer.
