>>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.

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.

4. Align the paint mark of special tool MB991613 connector

number 4 with the notch in clock spring connector number 2
(arrow in the illustration) to connect the connectors number
2 and 4.

5. Check that the resistance meets the standard value

between the terminals 22 and 23 of special tool MB991613
connector number 5.
