FRONT SEATBACK ASSEMBLY WITH SIDE-AIRBAG
MODULE CHECK
DANGER
Never attempt to measure the circuit resistance of the
air bag module (squib) even if you are using the spec-
ified tester. If the circuit resistance is measured with a
tester, accidental air bag deployment will result in
serious personal injury.
WARNING
If any improper part is found during the following
inspection, replace the front seatback assembly with
a new one. Dispose of the old one according to the
specified procedure. (Refer to
.)
1. Check the air bag module deployment section for dents or
deformation.
2. Check the connector for damage, the terminals for
deformation, and the harness for binds.
.
CLOCK SPRING CHECK
If any malfunction is found in the following inspections, replace
the clock spring with a new one.
1. Check the connectors and protective tube for damage, and
the terminals for deformation.
2. Visually check the case for damage.
3. Check to see that there is a change (continuity) between the
D-206 clock spring connector terminal and D-228 horn
switch connector.
CAUTION
Do not insert the probe directly to the terminal from the
front of the connector.
4. Insert special tool MB991222 from behind the airbag module
connector of the D-229 driver's side.
5. As shown in the Figure, connect the circuit tester to special
tool MB991222 and check to see that there is a charge
between the terminals.

impact sensor, if dents, cracking, deformation, or rust are present.
•
Replace the side impact sensor after the air bag has deployed.
NOTE: The illustration above shows the side impact sensor (RH). The position of the side impact sensor (LH)
is symmetrical to this.

REMOVAL AND INSTALLATION
M1524004100152
WARNING
•
Never attempt to disassemble or repair the seat belt pre-tensioner. If faulty, replace it.
•
Be extremely careful when handling the seat with pre-tensioner. Do not subject it to
shocks, drop it, bring it close to strong magnets or allow contact with water, grease or oil.
Always replace it with a new part if any dents, cracks or deformation is found.
•
Do not place anything on top of the seat belt pre-tensioner.
•
Do not expose the seat belt pre-tensioner to temperatures over 90
°C (194°F).
•
After operating the seat belt pre-tensioner, replace the seat belt pre-tensioner with a new
part.
•
Gloves and protective goggles should be worn when handling a seat belt pre-tensioner
once it has been used.
•
If disposing of a seat belt with pre-tensioner which has not yet been operated, its seat belt
pre-tensioner should be operated first before disposal. (Refer to
