DANGER

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

P.52Ba-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.

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.52Ba-48

.)

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.
