Safety airbag-25

Figure 8.3

d. Remove the steering wheel by removing the mounting screw from the mid-position. (Shut off the horn connector)

Caution

It is difficult to separate the steer from steering column due to the over meshing between spline and steering column,

in this case, do not forcibly remove the steer but screw off the bolt on the steering column and lift up the steer instead

(the forced removal will damage the clock spring since the connection between the steer and the spring)

Caution

Diagnose the safety airbag module circuit with electric diagnostic instrument without separating it.

Let the removed driver’s side safety airbag module bottom-side up and store it at a clean and dry place.

Store the clock spring in a clean and dry place.

9. Installation operation instructions

a.  The test before installation

The new safety airbag or clock spring must be tested before installation.

Caution

The safety airbag module must be abandoned after its release according to the procedure

Connect the accumulator negative

Connect the K-431 diagnostic instrument with the diagnostic interface (16 plug)

Caution

Place the ignition switch in OFF place when connect or shut off the 

 diagnostic instrument.

Place the ignition switch in ON position

Read the diagnostic circuit, check whether the safety airbag module is in normal condition except the failure regions.

Place the ignition switch in OFF position

Remove accumulator negative and wrap it with the tape for insulation.

Caution

Continue the operation 60 seconds after the removal of accumulator negative

Install the clock spring to the steer after its involution

 Clock spring’s central involution, clockwise screw the clock spring to the end, then turn it for 3 circles anticlockwise and make

    the involution with the marked sites

Safety airbag-26

Do the troubleshooting if the alarm lamp re-illuminates after its extinguishments following the 6-second-flashing (or it keeps

 illuminating from the very beginning)

10. Test

a. Driver’s side airbag module test (Figure8-3)

Check the following items and replace the corresponding safety airbag module part with anything abnormal with a new one.
Abandon the safety airbag’s old parts after its release according to the instructed procedure.

Caution

Do not jam the clock spring wiring harness during the steering wheel and safety airbag module assembly installation.

After the installation, rotate the steering wheel to left and right positions as enough as possible to confirm whether something

 abnormal is with it.

d. Post-installation test.

lightly rotate the steering wheel to the left and right to confirm whether something abnormal and noises will arise.(Driver’s side

safety airbag module, clock spring)

Place the ignition switch in ON place.

SRS alarm lamp flashes in 6 seconds and then extinguishes.

Caution

If without the clock spring central involution, the steering wheel will not be able to rotate at midway, or the clock spring

circuit will be damaged so that jeopardize SRS safety airbag’s normal activities.

The spacer must be removed after replacing a clock spring with a new one, otherwise it will damage the clock spring.

c.   Steering wheel and safety airbag module assembly installation.

Install the steering wheel and safety airbag module assembly after clock spring’s central involution.

Caution

The safety airbag module (squib) circuit resistance can even not be tested by the designated tester.

When testing the resistance with an experimental instrument, sometimes the improper release will be caused by the

static interference because of the current in explosion pipe and cause some major damaging accidents.

Whether depression, crack or deformation is with the shroud.

 Whether the joint is broken and the terminal is deformed.

Whether depression, crack or deformation is with the gas generator shield.

Safety airbag module. Installation status.

Caution

Replace the safety airbag with depression, crack or deformation with a new one. Its old parts must be abandoned after

its release.

Safety airbag-27

b. Clock spring test (figure 8.5,figure 8.6)

Check the following items and replace the clock spring with anything abnormal (even it is quite tiny) with a new one

Whether the joint and protection tube are broken and the terminal is deformed.

Whether the shield is damaged.

Check the connection between clock spring’s upper joint terminal and it’s corresponding bottom terminal.

Plug in a thin probe from the 3# joint of clock spring.

Caution

Do not directly plug in the probe from the bottom of the joint.

5 As showed in Figure 8.5,Plug a thin probe into the current tester to check the connection of the terminal.

Safety airbag module abandoning instruction

Carry out the operation according to the following procedure to abandon a safety airbag module or a vehicle with the SRS

safety airbag. First of all, release the safety airbag.

Unreleased safety airbag module abandoning

Caution

First release the SRS safety airbag when abdbdon it.

Release the safety airbag outside the vehicle to replace the safety airbag module.

Conduct the operation somewhere next to a smoke tester due to the smoke during the safety airbag’s release.

Tell the people to cover their ears and try to conduct the operation somewhere far away from the residential area due

to the big noise during the safety airbag’s release.

Remove the accumulator positive and negative and remove the accumulator off the vehicle.

Caution

Continue the operation 60 seconds after the removal of accumulator positive and negative.

Release the safety airbag module according to the following procedure.

1. Driver’s side safety airbag module

a.  Remove the blocking lever
b. Remove the clock spring 2# joint and instrument panel wiring harness joint (yellow)(figure 8.6)

Caution

The clock spring joint will short automatically after the removal of clock spring from the instrument wiring harness,

which can prevent any possible major accident caused by the incorrect release of driver’s side safety airbag module duo

to the static interference from happening.

c.  Connect the SRS safety airbag translation wring harness with 2 6m plus release wiring harnesses, wrap the joint part with

    insulating tape for insulation.
