side.1. Check the drive shaft (referring to page 111).
2. Discharge the oil in gearbox.(a) Disassemble oil plug and gasket to discharge the oil in
gearbox.
(b) Change with a new gasket and assemble oil discharging
plug.

4. Disassemble fixing nut of drive shaft [64000083](a) Use special tool and hammer to unclench the concave part
of fixing nut.
(b) Disassemble the fixing nut.5. Disassemble speed sensor assembly of left front
wheels (equipping with ABS) [67000020](a) Disassemble the bolt, and disassemble sensor wiring har-
ness and brake hose from the absorber.
(b) Disassemble the bolt, and disassemble speed sensor from

(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.
Liking that shown in figure: some joints of wiring harness use the female joints in the right part of figure,
some designs of helix cable is similar with the joints in the left part.
III.Connect the connecting joint of lower helix cable and wiring harness of steering wheel.
1. Liking that shown in figure, align locking part of male joint and sliding block of female joint in same
direction to avoid mutual friction.

Diagnostic procedure
When starting to check, firstly, use special diagnostic tool and ECU to make diagnostic communication to
find the reason of malfunction, if communication could not implement, make following inspection:
(1) Check the battery
a. Measure the voltage of battery
b. Is the voltage higher than 9V?
Yes: make next operation,
No: Power supply of battery is lack, check the charging/discharging system, then make step 5.
(2) Check the conduction of wiring harness between ECU and combination meter.
a. Set ignition switch at LOCK position,
b. Cut off cathode of battery,
c. Open the defending board of central channel,
d. Disconnect the connector of instrument package ,
e. Connect the cathode of battery,
f. Set ignition switch at ON position,
g. Check whether the terminal voltage of corresponding connector of instrument is 12V (connecting
wire of power supply and instrument)
Yes: make next step,
No: check the circuit part, then make step 5 after repairing it.
h. Set ignition switch at LOCK position,
i. Check whether the corresponding terminal of instrument connector conducts with corresponding
terminal of diagnostic interface (diagnose two ends of K wire),
Yes: make next step,
No: repair or change the wiring harness, then make step 5.
j. Guarantee cathode of battery is cut off and keep this state for one minutes at least, cut off connec-
tor of ECU.
k . Disconnect the plug of instrument package,
l. Check whether it conducts between ECU plug voltage, K wire, airbag indicating light terminal and
plug of instrument package ?
Yes: make next operation,
No: change the wiring harness, then make the step 5.
m. Disassemble the ECU to check whether the terminal is good, and the short circuit stick is broken.
Yes: change the ECU,
No: connect the ECU connector again, then make next operation.
