AIRBAG CONTROL MODULE (Continued)
WARNING: THE AIRBAG CONTROL MODULE CON-
TAINS THE IMPACT SENSOR, WHICH ENABLES
THE SYSTEM TO DEPLOY THE AIRBAGS. NEVER
STRIKE OR KICK THE AIRBAG CONTROL MODULE,
AS IT CAN DAMAGE THE IMPACT SENSOR OR
AFFECT ITS CALIBRATION. IF AN AIRBAG CON-
TROL MODULE IS ACCIDENTALLY DROPPED DUR-
ING SERVICE, THE MODULE MUST BE SCRAPPED
AND REPLACED WITH A NEW UNIT. FAILURE TO
OBSERVE THIS WARNING COULD RESULT IN ACCI-
DENTAL, INCOMPLETE, OR IMPROPER AIRBAG
DEPLOYMENT AND POSSIBLE OCCUPANT INJU-
RIES.
(1) Position the Airbag Control Module (ACM)
beneath the instrument panel.
(2) Reconnect the cross body wire harness connec-
tor for the ACM to the ACM connector receptacle
(Fig. 7). Be certain that the connector latches and the
white Connector Positive Assurance (CPA) locks are
fully engaged.
(3) Carefully position the ACM to the mounting
bracket that is welded onto the floor panel transmis-
sion tunnel (Fig. 6). When the ACM is correctly posi-
tioned, the locator pins on the ACM housing will be
engaged in the locator holes in the mounting bracket,
and the arrow on the ACM label will be pointed for-
ward in the vehicle.
(4) Install and tighten the four screws that secure
the ACM to the mounting bracket welded onto the
floor panel transmission tunnel. Tighten the screws
to 14 N·m (125 in. lbs.).
(5) If the vehicle is equipped with the optional
ABS brakes, reinstall the acceleration switch onto
the left side of the mounting bracket on the floor
panel transmission tunnel. (Refer to 5 - BRAKES/
ELECTRICAL/G-SWITCH - INSTALLATION).
(6) Restore the carpet on the right and left sides of
the floor panel transmission tunnel to its proper posi-
tion beneath the instrument panel.
(7) Do not reconnect the battery negative cable at
this time. The airbag system verification test proce-
dure should be performed following service of any
airbag system component (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - VERI-
FICATION TEST).

CLOCKSPRING

DESCRIPTION

The clockspring assembly is secured with two inte-
gral plastic latches onto the steering column lock
housing near the top of the steering column behind
the steering wheel (Fig. 8). The clockspring consists
of a flat, round molded plastic case with a stubby tail
that hangs below the steering column and contains

two connector receptacles that face toward the
instrument panel. Within the plastic housing is a
spool-like molded plastic rotor with a large exposed
hub. The upper surface of the rotor hub has a large
center hole, two large flats, and two or three short
pigtail wires with connectors. The third pigtail wire
is used on vehicles equipped with the optional speed
control system. The lower surface of the rotor hub
has a molded plastic turn signal cancel cam consist-
ing of two lobes that are molded into the rotor.
Within the plastic case and wound around the rotor
spool is a long ribbon-like tape that consists of sev-
eral thin copper wire leads sandwiched between two
thin plastic membranes. The outer end of the tape
terminates at the connector receptacles that face the
instrument panel, while the inner end of the tape
terminates at the pigtail wires on the hub of the
clockspring rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-
centered and with a locking pin that snaps into a
receptacle on the rotor and is engaged between two
tabs on the upper surface of the rotor case. The lock-
ing pin secures the centered clockspring rotor to the
clockspring case during shipment, but the locking pin
must be removed from the clockspring after it is
installed on the steering column. (Refer to 8 - ELEC-
