3. Driver side airbag module installation sequence (after steering wheel i\
nstallation is completed)
(a) Install the horn's wire harness.
(b) Install the airbag module executing equipment's (gas generator) wire harness.
(c) Place the airbag module onto the steering wheel's proper installation position (avoid heavy knocking while
placing).
(d) Tighten the airbag module mounting bolt.
(e) Connect the battery's negative (-) terminal.
(f) Inspection after installation.
Auxiliary airbag removal and installation
1. Auxiliary airbag removal
(a) Remove the glove box.
(b) Pull out the dashboard wire harness and the auxiliary airbag wire harness connectors.
(c) Remove the airbag mounting bolt.
(d) Remove the upper dashboard.
(e) Remove the auxiliary airbag's two mounting nuts.
(f) Press the buckle and remove the auxiliary airbag.
2. Installation sequence for the auxiliary airbag is reverse to the removal\
sequence.
Caution: Please do not place anything on the auxiliary airbag, as to avoid accidents while deploying
the airbag.
Operation essentials
1. Driver side airbag and steering wheel removal
Caution: The following operations should only be performed after the battery's negative (-) terminal
has been disconnected, and after the ignition switch key has been pulled\
out for 60 s.
(a) Remove the mounting screws from the two holes under the steering wheel bottom cap, and lightly pick up
the driver side airbag module.
(b) Pull out the deployed airbag module's wire harness and the horn line, and remove the airbag module\
.
Attention: Diagnose the airbag module's circuit with an electrical measuring instruments but do not
dismantle it. Face the bottom of the removed passenger side airbag upwards and store it in a clean
and dry place.
(c) Remove the steering wheel mounting bolt on the steering column.
Caution: Due to the over-tight occlusion of the spline and column, the steering wheel and steering
column may be hard to separate, in which case make sure not to use force to remove the steering
wheel. The correct method is to tighten the screw into the column just a bit, and then pull up the
steering wheel (because the steering wheel bottom is connected to the clock spring, if force is used to
remove it, it may damage it).
2. Clock spring removal
(a) After steering wheel removal is completed, remove the combination switch hood.
(b) Pull out the dashboard wire harness connectors under the clock spring.
(c) Take off the clock spring.
Caution: Store the removed clock spring in a clean and dry place.
3. Installation notes
(a) Inspection before installation, inspection of driver side airbag module.
(b) Inspect the new airbag or clock spring before installing them.
4. Driver side airbag module inspection
Inspect each of the following items. If any faults are found, replace with a new corresponding airbag module
part. Discard the old components after they have been deployed in the pr\
oper order.
(a) Whether the cover sunken or depressed, cracked, or deformed.
(b) Whether the wire harness has broken connectors and deformed terminals.
(c) Whether the gas generator's housing is sunken or depressed, cracked, or deformed.
(d) Airbag module installation status.
Caution: The specified measuring instrument cannot measure the airbag module (tube rupture) circuit
resistance. Test the resistance with a testing instrument. There is an electric current in the tube rup-
ture which may lead to accidental deployment due to static electricity a\
nd cause serious accidents.
5. Clock spring inspection
Inspect each of the following items. If any fault is found, replace with\
a new clock spring.
