DRIVER'S AIR BAG MODULE AND CLOCK SPRING
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-391
Alignment of mating marks
(1) Turn the clock spring clockwise fully.
(2) Turn the clock spring counterclockwise approximately
three and 3/4 turns to align the mating marks.
(3) Check that the white roller can be seen from the window
for checking the neutral point when the mating marks are
aligned.
NOTE: If the white roller cannot be seen, the neutral point
is not aligned correctly.
(4) Install the clock spring to the column switch.

>>C<< STEERING WHEEL ASSEMBLY/DRIVER’S
AIR BAG MODULE ASSEMBLY INSTALLATION
CAUTION
When installing the steering wheel and air bag module,
ensure that the harness of the clock spring does not
become caught or tangled.
1. Before installing the steering wheel and air bag module, turn
the vehicle’s front wheels to the straight-ahead position and
align the mating marks of the clock spring.
2. After securing the steering wheel, turn the steering wheel all
the way in both directions to confirm that the steering wheel
rotation is normal.

AIR BAG MODULE CHECK
DANGER
Never attempt to measure the circuit resistance of the
air bag modules (squib), even if you are using the
specified tester. If the circuit resistance is measured
with a tester, accidental air bag deployment will
result, and possible serious personal injury.
WARNING
If any component damage is found during the follow-
ing inspection, replace the air bag module with a new
one. Dispose of the old one according to the specified
procedure (Refer to
).
1. Check the pad cover for dents, cracks or deformation.
2. Check the connectors for damage, the terminals for
deformation, and the harness for binding.
3. Check the air bag inflator case for dents, cracks or
deformation.
4. Install the air bag module (driver’s side) to the steering
wheel and check fit and alignment with the steering wheel.
5. Install the air bag module (front passenger’s side) to the
instrument panel and front deck crossmember and check fit
and alignment.
.
CLOCK SPRING
If any malfunction is found in the following inspections, replace
the clock spring with a new one.
1. Check the connectors and protective tubes for damage and
the terminal for deformation.
2. Check the case for damage.
3. Check that the continuity exists between the following
connector terminals.
• C-205 connector terminal 1 and horn switch connector
• C-205 connector terminal 2 and C-202 connector terminal 5
• C-205 connector terminal 3 and C-202 connector terminal 4
• C-205 connector terminal 4 and C-202 connector terminal 3
• C-205 connector terminal 5 and C-202 connector terminal 2
• C-205 connector terminal 6 and C-202 connector terminal 1

CAUTION
Never insert the probe directly to the terminals from the
front of the connector.
4. Check the continuity between the driver's air bag module
connectors according to the following procedures.
(1) Insert special tool extra fine probe (MB992006) from the
backside of driver's air bag module connector.
(2) Connect the circuit tester to the special tool as shown in
the figure, and check the continuity among terminal No. 1
− 2 or No. 3 − 4.

REMOVAL AND INSTALLATION
M1524047300063
WARNING
•
Never attempt to disassemble or repair the air bag modules. If faulty, replace it.
•
Do not drop the air bag modules or allow contact with water, grease or oil. Replace it if a
dent, crack, deformation or rust is detected.
•
The air bag modules should be stored on a flat surface with the pad cover facing upward.
Do not place anything on top of it.
•
Do not expose the air bag modules to temperatures over 93
°
C (200
°
F).
•
After deployment of the air bag, replace the air bag module with a new one.
•
Wear gloves and safety glasses when handling air bags that have already deployed.
•
An undeployed air bag module should only be disposed of in accordance with the proce-
dures (Refer to
).
•
When removing and installing the front passenger seat, be sure to carry out accuracy
check of the occupant classification sensor after the seat has been installed in the vehicle
