).
- Steering wheel, steering column
assembly
(1) Check that the
driver’s air bag module is installed to the
steering wheel correctly. (2) Check the steering
wheel for noise, binding, operational failure, and
play. (3) Check the shock absorbing mechanism of
steering column shaft assembly (Refer to GROUP 37
- On-vehicle Service ).

3.Instrument panel assembly
(Refer to GROUP 52A - Instrument Panel Assembly ).
|
|
4.Check the wiring harness
for binding, the connector for damage, and the terminal for
deformation (Refer to ).
|
|
1.Check the SRS air bag
components and seat belt assembly according to the following
procedures.
|
|
2.Check the operation of
seat belt. If the seat belt cannot be drawn out, replace the
seat belt with a new one.
|
|
3.If dents, fractures,
deformation or frays are found by visual inspection, the
relevant SRS airbag component or the seat belt assembly
(such as pre-tensioner, retractor, buckle) must be
replaced.
|
|
4.For removal and
installation of parts, refer to
