If the stored DTC information is successfully erased,
go to Step 9.
(9) Turn the ignition switch to the Off position for
about fifteen seconds, and then back to the On posi-
tion. Observe the airbag indicator in the instrument
cluster. It should illuminate for six to eight seconds,
and then go out. This indicates that the supplemen-
tal restraint system is functioning normally and that
the repairs are complete. If the airbag indicator fails
to light, or lights and stays on, there is still an active
supplemental restraint system fault or malfunction.
Refer to the appropriate diagnostic information to
diagnose the problem.

AIRBAG CONTROL MODULE
DESCRIPTION
The Airbag Control Module (ACM) is also some-
times referred to as the Occupant Restraint Control-
ler (ORC) (Fig. 7). The ACM is concealed below the
instrument panel center stack in the passenger com-
partment of the vehicle, where it is secured by three
screws to a stamped steel mounting bracket welded
onto the top of the floor panel transmission tunnel
just forward of the instrument panel center support
bracket. Concealed within a hollow in the center of
the die cast aluminum ACM housing is the electronic
circuitry of the ACM which includes a microproces-
sor, an electronic impact sensor, an electronic safing
sensor, and an energy storage capacitor. A stamped
metal cover plate is secured to the bottom of the
ACM housing with four screws to enclose and protect
the internal electronic circuitry and components.
An arrow printed on the label on the top of the
ACM housing provides a visual verification of the
proper orientation of the unit, and should always be
pointed toward the front of the vehicle. The ACM
housing has integral mounting flanges on three cor-
ners. The mounting flange to the left of the connector
receptacle has an integral locating pin on its lower
surface. Both left side flanges have round mounting
holes, while the flange on the right side has a slotted
mounting hole. A molded plastic electrical connector
with two receptacles, one containing twenty-four ter-
minal pins and the other containing thirty-two termi-
nal pins, exits the rearward facing side of the ACM
housing. These terminal pins connect the ACM to the
vehicle electrical system through two dedicated takeouts and connectors of the instrument panel wire
harness.
The impact sensor and safing sensor internal to
the ACM are calibrated for the specific vehicle, and
are only serviced as a unit with the ACM. In addi-
tion, there are unique versions of the ACM for light
and heavy-duty models, and for vehicles with or
without the optional side curtain airbags. The ACM
cannot be repaired or adjusted and, if damaged or
faulty, it must be replaced.
OPERATION
The microprocessor in the Airbag Control Module
(ACM) contains the supplemental restraint system
logic circuits and controls all of the supplemental
restraint system components. The ACM uses
On-Board Diagnostics (OBD) and can communicate
with other electronic modules in the vehicle as well
as with the DRBIIItscan tool using the Programma-
ble Communications Interface (PCI) data bus net-
work. This method of communication is used for
control of the airbag indicator in the ElectroMechani-
cal Instrument Cluster (EMIC) and for supplemental
restraint system diagnosis and testing through the
16-way data link connector located on the driver side
lower edge of the instrument panel. (Refer to 8 -
ELECTRICAL/INSTRUMENT CLUSTER/AIRBAG
INDICATOR - OPERATION).
The ACM microprocessor continuously monitors all
of the supplemental restraint system electrical cir-
cuits to determine the system readiness. If the ACM
detects a monitored system fault, it sets an active
and stored Diagnostic Trouble Code (DTC) and sends
electronic messages to the EMIC over the PCI data
bus to turn on the airbag indicator. An active fault
only remains for the duration of the fault, or in some
cases for the duration of the current ignition switch
cycle, while a stored fault causes a DTC to be stored
in memory by the ACM. For some DTCs, if a fault
does not recur for a number of ignition cycles, the
ACM will automatically erase the stored DTC. For
other internal faults, the stored DTC is latched for-
ever.
In standard cab models, the ACM also monitors a
resistor multiplexed input from the passenger airbag
on/off switch and provides a control output for the
Off indicator in the switch through a passenger air-
bag indicator driver circuit. If the passenger airbag
on/off switch is set to the Off position, the ACM turns
on the passenger airbag on/off switch Off indicator
and will internally disable the passenger airbag from
being deployed. The ACM also turns on the on/off
switch Off indicator for about seven seconds each
time the ignition switch is turned to the On position
as a bulb test. Following the bulb test, the ACM con-
trols the status of the Off indicator based upon the

AUTOMATIC LOCKING
RETRACTOR
DESCRIPTION
The seat belt retractors used in all seating posi-
tions include an inertia-type, emergency locking
mechanism as standard equipment (Fig. 9). However,
the retractor locking mechanism for the passenger
side front seating position is mechanically switchable
from an emergency locking retractor to an automatic
locking retractor. The primary function of this fea-
ture is to securely accommodate a child seat in the
passenger side front seating position of the vehicle
without the need for a self-cinching seat belt tip half
latch plate unit or another supplemental device that
would be required to prevent the seat belt webbing
from unwinding freely from the retractor spool of an
inertia-type emergency locking retractor mechanism.
The automatic locking mechanism is integral to the
passenger side front seat belt and retractor unit and
is concealed beneath a molded plastic cover located
on the same side of the retractor spool as the seat
belt tensioner housing. The retractor is secured to
the inner B-pillar on the right side of the vehicle and
is concealed beneath the molded plastic inner B-pil-lar trim. The automatic locking mechanism cannot be
adjusted or repaired and, if faulty or damaged, the
entire passenger side front seat belt and retractor
unit must be replaced.
OPERATION
The automatic locking mode of the retractor is
engaged and the retractor is switched from operating
as a standard inertia-type emergency locking retrac-
tor by first buckling the combination lap and shoul-
der belt buckle. Then grasp the shoulder belt and
pull all of the webbing out of the retractor. Once all
of the belt webbing is extracted from the spool, the
retractor will automatically become engaged in the
pre-locked automatic locking mode and will make an
audible clicking or ratcheting sound as the shoulder
belt is allowed to retract to confirm that the auto-
matic locking mode is now engaged. Once the auto-
matic locking mode is engaged, the retractor will
remain locked and the belt will remain tight around
whatever it is restraining.
The retractor is returned to standard emergency
locking mode by unbuckling the combination lap and
shoulder belt buckle and allowing the belt webbing to
be almost fully retracted onto the retractor spool. The
emergency locking mode is confirmed by the absence
of the audible clicking or ratcheting sound as the belt
webbing retracts. This mode will allow the belt to
unwind from and wind onto the retractor spool freely
unless and until a predetermined inertia load is
sensed, or until the retractor is again switched to the
automatic locking mode.

This model is equipped with a Lower Anchors and
Tether for CHildren, or LATCH child restraint
anchorage system (Fig. 10) or (Fig. 11). The LATCH
system provides for the installation of suitable child
restraints in certain seating positions without using
the standard equipment seat belt provided for that
seating position. Standard cab models are equipped
with a fixed-position child restraint upper tether
anchor for the front center and outboard seating posi-
tions, and child restraint lower anchors for the front
outboard seating position. Quad cab models are
equipped with a fixed-position child restraint upper
tether anchor strap for the rear center and both rear
outboard seating positions, and child restraint lower
anchors for both rear outboard seating positions. All
front seat child restraint anchors are deleted on quad
cab models.
The two upper tether anchors for standard cab
models are integral to the upper cab back panel rein-
forcement and are concealed behind individual trim
cover and bezel units that are integral to the cab
back trim panel (Fig. 12). These upper tether anchors
cannot be adjusted or repaired and, if faulty or dam-
aged, they must be replaced as a unit with the upper
cab back panel reinforcement. The upper tether
anchor trim covers and bezels are serviced as a unit
with the cab back trim panel.The three upper tether anchor straps for quad cab
models are secured to the upper cab back panel rein-
forcement with screws (Fig. 13). These anchor straps
are concealed behind the upright rear seat back. The
upper tether anchor straps are available for individ-
ual service replacement.
The lower anchors for all models are integral to
their respective front or rear seat cushion frame (Fig.
14) or (Fig. 15). Round markers with an imprinted
child seat icon on the standard cab front seat back
trim cover helps identify the anchor locations for that
application because they may be otherwise difficult to
see with the seat back in the upright position. These
lower anchors are each constructed from round steel
bar stock that is formed into a U-shape, then
securely welded at each end to the seat cushion
frame. They are each accessed from the front of their
respective seats, at each side where the seat back
meets the seat cushion. These lower anchors cannot
be adjusted or repaired and, if faulty or damaged,
they must be replaced as a unit with the seat cush-
ion frame. On quad cab models, if the lower anchors
have been bent or broken as a result of a vehicle col-
lision, the latch for the affected rear seat cushion
frame unit must also be replaced.
