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.

Connect the connector securely and route the harnesses not to 
lie off the cover hole.

.

>>E<< POST-INSTALLATION INSPECTION

1. Reconnect the negative (

−) battery cable.

2. Turn the ignition switch to “ON” position.
3. Does the "SRS" warning light illuminate for approximately 

seven seconds, and go out?

4. If yes, the SRS system is functioning properly. If not, refer to

.

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 

P.52B-417

).

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 

P.52B-417
