INTERIOR Supplemental Restraint System (SRS)
CLOCK SPRING
The clock spring is provided between the steering
wheel (air bag module) and column switch body
(steering column).
The clock spring provides harness connections be-
tween the air bag module and SRS diagnostic unit,
between the horn switch and dashboard wiring har-
ness, and between the remote control switch and
dashboard wiring harness.
The clock spring consists of a neutral position indica-
tion mechanism, flat cable, upper case, lower case,
rotor, etc.
The flat cable is loosely wound like a coil, and is
held in the upper and lower cases with one of its
ends mounted to the rotor and the other end
mounted to the upper case. The upper and lower
cases are mounted to the steering column. The
rotor is coupled with. the steering shaft. Rotation
of the steering wheel (steering shaft) causes the
rotor to rotate. Accordingly, the flat cable is wound
round the rotor or loosened, and operates with the
rotor as the steering wheel is turned.
Caution
Make sure that the clock spring is never disas-
sembled.

INTERIOR Supplemental Restraint System (SRS)
NEUTRAL POSITION INDICATION MECHANISM
The system consists of a ring gear (number of teeth:
90) provided in the upper case, a transparent cover
mounted on the rotor with screws, and a gear (num-
ber of teeth: 80) which is in mesh with the ring
gear and is driven by the convex portion of the
cover.
The upper case is mounted on the steering column
and is always held in position.
The rotor coupled with the steering shaft and always
operates with the steering wheel. The gear is always
kept in mesh with the ring gear by the convex portion
of the cover. If the rotor turns through a rotation,
the convex portion of the cover also turns through
a rotation. So the gear is displaced in the opposite
direction to the rotating direction of the rotor by
the difference in the number of teeth between the
gear and ring gear or by 10 teeth.
Markings R2, 1, NEUTRAL, 1, and 2L are made
on the gear for every teeth. An alignment mark
is made on the upper case. The clock spring is
placed in the neutral (straight ahead) position by
lining up the alignment mark with the mark NEU-
TRAL of the gear. The mark
on the gear indicates
that the rotor has been turned clockwise, whereas
the mark
indicates counterclockwise rotation of
the rotor.

SRS WARNING LIGHT
The SRS warning light is provided at the left side of the combina-
tion meter.
When the SRS is in good order, the light should illuminate
for approximately 7 seconds after the ignition key has been
turned ON, or the engine has been started, and will then go
out.
The SRS warning light has only one display area but contains
two lights. Even if one of the lights is defective, the other one
can be lit.
The SRS warning light is checked by the SRS diagnostic unit
for defective light.
