>>B<< CLOCK SPRING INSTALLATION 

WARNING

Ensure that the clock spring's mating marks are prop-
erly aligned. If not, the steering wheel may not rotate 
completely during a turn, or the flat cable in the clock 
spring could be damaged. This would prevent normal 
SRS operation and possibly cause serious injury to 
the driver. 

1. Check that the front wheels is in the straight-ahead position. 
2. Align the mating marks of the clock spring. Turn the front 

wheels to the straight-ahead position. Then install the clock 
spring to the column switch.

Mating Mark Alignment
Turn the clock spring clockwise fully. Then turn it back approxi-
mately 3 4/5 turns counterclockwise to align the mating marks. 

.

>>C<< STEERING WHEEL INSTALLATION 

CAUTION

When installing the steering wheel, ensure that the har-
ness of the clock spring does not become caught or tan-
gled.
1. Before installing the steering wheel, 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.

.

>>D<< AIR BAG MODULE INSTALLATION (DRIVER'S SIDE)
1. Connect the air bag module connector securely.
2. Tighten the air bag module mounting screws to 8.8 N

⋅m (78 

in-lb).

>>E<< POST-INSTALLATION INSPECTION
1. Reconnect the negative (

−) battery cable. 

2. Turn the ignition key to the "ON" position. 
3. Does the "SRS" warning light illuminate for approximately 7 

seconds, and the remain off for at least 5 seconds after 
turning "OFF?" 

4. If yes, the SRS system is functioning properly. 

If no, consult

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 
in serious personal injury.

WARNING

•

If any component damage is found during the fol-
lowing inspection, replace the air bag module with 
a new one. Dispose of the old one according to the 
specified procedure. (Refer to 

P.52B-96

.) 

•

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 mea-
sured with a tester, accidental air bag deployment 
will result in serious personal injury. 

1. Check the pad cover for dents, cracks or deformation. 
2. Check the connectors for damage, the terminals for 

deformation, and the harness for binds. 

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 wheel. 

5. Install the air bag module (front passenger's side) to the 

instrument panel and crossmember and check fit and 
alignment. 

6. Install the air bag module cover (front passenger's side) to 

the instrument panel to check fit and alignment.

CLOCK SPRING CHECK 
Required Special Tool:
MB991613: SRS Check Harness 
If, even one abnormality is discovered in Steps 1 to 5, 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 continuity.

<Vehicles without auto-cruise control>

• Check continuity between the number 1 connector terminal 

3 and number 3 connector.

<Vehicles with auto-cruise control>

• Check continuity between the number 1 connector terminal 

1 and number 4 connector terminal 2, number 1 connector 
terminal 2 and number 4 connector terminal 1, number 1 
connector 3 and number 3 connector, number 1 connector 
terminal 4 and number 4 connector terminal 3 respectively.
