CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
3. Connect scan tool MB991958 to the data link connector.
4. Turn the ignition switch to the “ON” position.
5. Check DTC, using scan tool MB991958 to ensure entire

SRS system operates properly.
At this time, check that DTC except 21 and 24 is not set.

DANGER

Wait at least 60 seconds after disconnecting the bat-
tery cable before doing any further work.(Refer to

P.52B-18

WARNING

Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER
HANDLING.

6. Turn the ignition key to the "LOCK" (OFF) position.

Disconnect the negative (

−) battery cable and tape the

terminal to prevent accidental connection and air bag
deployment.

>>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 harness in the
clock spring could be damaged. This would prevent
normal SRS operation and possibly cause serious
injury to the driver.

Align the mating marks of the cock 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 3/4 turns counterclockwise to align the mating marks.

>>C<< STEERING WHEEL AND AIR BAG MODULE
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.

INSPECTION

M1524002500455

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 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-234

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 wheel.

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

instrument panel and front deck 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.

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

P.52B-234

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-205 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.
