BCLOCK SPRING INSTALLATION
Align the mating marks of the clock spring and, after turning
the front wheels to the straight-ahead position, install the
clock spring to the column switch.
Mating Mark Alignment
Turn the clock spring clockwise fully, and then turn back it
approx. 3 4/5 turns counterclockwise to align the mating marks.
Caution
If the clock spring’s mating marks are not properly aligned,
the steering wheel may not be completely rotational during
a turn, or the flat cable within the clock spring may be
severed, obstructing normal operation of the SRS and
possibly leading to serious injury to the vehicle’s driver.
CSTEERING WHEEL INSTALLATION
1. Before installation the steering wheel, be sure to first
turn the vehicle’s front wheels to the straight-ahead
position and align the mating marks of the clock spring.
Caution
Be sure when installing the steering wheel, that the
harness of the clock spring does not become caught
or tangled.
2. After clamping, turn the steering wheel all the way in
both directions to confirm that steering is normal.
DPOST-INSTALLATION INSPECTION
1. Turn the steering wheel lightly to the left and right to
check if it can be operated properly without any
abnormality.
2. Reconnect the negative battery terminal.
3. Turn the ignition key to the “ON” position.
4. Does the “SRS” warning lamp illuminate for about 7
seconds, and then remain extinguished for at least 5
seconds after turning OFF?
5. If yes, SRS system is functioning properly.
If no, consult page 52B-6.

INSPECTION
AIR BAG MODULE CHECK
If any improper part is found during the following inspection,
replace the air bag modules with a new one.
Dispose the old one according to the specified procedure.
(Refer to P.52B-32.)
Caution
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 bags deployment will result in serious
personal injury.
1. Check pad cover for dents, cracks or deformation.
2. Check connectors for damage, terminals for deformation,
and harness for binds.
3. Check air bag inflator case for dents, cracks or
deformation.
4. Install the air bag module to steering wheel to check
fit or alignment with the wheel.
Caution
If dents, cracks, deformation, or rust are discovered in
the air bag module, replace it with a new one.
Dispose of the old one according to the specified
procedure. (Refer to P.52B-32.)
CLOCK SPRING CHECK
If, as result of following checks, even one abnormal point
is discovered, replace the clock spring with a new one.
1. Check connectors and protective tube for damage, and
terminals for deformation.
2. Visually check the case for damage.
