THE SYSTEM CAPACITOR TO DISCHARGE BEFOREPERFORMING FURTHER DIAGNOSIS OR SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO
TAKE THE PROPER PRECAUTIONS COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
(1) During the following test, the battery negative
cable remains disconnected and isolated, as it was
during the supplemental restraint system component
removal and installation procedures.
(2) Be certain that the DRBIIItscan tool contains
the latest version of the proper DRBIIItsoftware.
Connect the DRBIIItto the 16-way Data Link Con-
nector (DLC). The DLC is located on the driver side
lower edge of the instrument panel, outboard of the
steering column (Fig. 5).
(3) Turn the ignition switch to the On position and
exit the vehicle with the DRBIIItscan tool.
(4) Check to be certain that nobody is in the vehi-
cle, then reconnect the battery negative cable.
(5) Using the DRBIIIt, read and record the active
(current) Diagnostic Trouble Code (DTC) data.
(6) Next, use the DRBIIItto read and record any
stored (historical) DTC data.
(7) If any DTC is found in Step 5 or Step 6, refer
to the appropriate diagnostic information.
(8) Use the DRBIIItto erase the stored DTC data.
If any problems remain, the stored DTC data will not
erase. Refer to the appropriate diagnostic informa-
tion to diagnose any stored DTC that will not erase.

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 secured with
four screws to the top mounting surface of a stamped
steel bracket welded onto the top of the floor panel
transmission tunnel forward of the instrument panel
center support bracket and below the instrument
panel center stack in the passenger compartment of
the vehicle (Fig. 7). Concealed within a hollow in the
center of the die cast aluminum ACM housing is the
electronic circuitry of the ACM which includes a
microprocessor, an electronic impact sensor, an elec-
tromechanical 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.
The ACM housing has integral mounting flanges
on each side. Two of the mounting flanges, one on
each side, have an integral locating pin on their
lower surface. The left flanges have round mounting
holes, while the flanges on the right side have slotted
mounting holes. An arrow cast into the top of the
ACM housing near the rear provides a visual verifi-
cation of the proper orientation of the unit, and
should always be pointed toward the front of the
vehicle. A molded plastic electrical connector recepta-
cle containing twenty-three terminal pins exits the
rearward facing side of the ACM housing. These ter-
minal pins connect the ACM to the vehicle electrical
system through a dedicated take out and connector of
the instrument panel wire harness.
The impact sensor and safing sensor internal to
the ACM are calibrated for the specific vehicle, andare only serviced as a unit with the ACM. 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 front supplemental restraint sys-
tem logic circuits and controls all of the front supple-
mental 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 front supplemental restraint system electrical
circuits 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, 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
forever.
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 if an impact is detected that is suffi-
cient for an airbag deployment. The ACM also turns
on the on/off switch Off indicator for about seven sec-
onds each time the ignition switch is turned to the
On position as a bulb test. Following the bulb test,
the ACM controls the status of the Off indicator
based upon the resistance of the input from the on/off
switch. The ACM will also set and/or store a DTC for
faults it detects in the passenger airbag on/off switch
circuits, and will turn on the airbag indicator in the
EMIC if a fault has been detected.

8O - 10 RESTRAINTSDR

On models equipped with optional side curtain air-
bags, the ACM communicates with both the left and
right Side Impact Airbag Control Modules (SIACM)
over the PCI data bus. The SIACM notifies the ACM
when it has detected a monitored system fault and
stored a DTC in memory for its respective side cur-
tain airbag system, and the ACM sets a DTC and
controls the airbag indicator operation accordingly.
The ACM receives battery current through two cir-
cuits; a fused ignition switch output (run) circuit
through a fuse in the Integrated Power Module
(IPM), and a fused ignition switch output (run-start)
circuit through a second fuse in the IPM. The ACM
receives ground through a ground circuit and take
out of the instrument panel wire harness. This take
out has a single eyelet terminal connector that is
secured by a ground screw to the instrument panel
support structure. These connections allow the ACM
to be operational whenever the ignition switch is in
the Start or On positions. The ACM also contains an
energy-storage capacitor. When the ignition switch is
in the Start or On positions, this capacitor is contin-
ually being charged with enough electrical energy to
deploy the front supplemental restraint components
for up to one second following a battery disconnect or
failure. The purpose of the capacitor is to provide
backup supplemental restraint system protection in
case there is a loss of battery current supply to the
ACM during an impact.
Two sensors are contained within the ACM; an
electronic impact sensor, and a safing sensor. The
electronic impact sensor is an accelerometer that
senses the rate of vehicle deceleration, which pro-
vides verification of the direction and severity of an
impact. The safing sensor is an electromechanical
sensor within the ACM that provides an additional
logic input to the ACM microprocessor. The safing
sensor is a normally open switch that is used to ver-
ify the need for a front supplemental restraint
deployment by detecting impact energy of a lesser
magnitude than that of the electronic impact sensor,
and must be closed in order for the front airbags or
seat belt tensioners to deploy. A pre-programmed
decision algorithm in the ACM microprocessor deter-
mines when the deceleration rate as signaled by the
impact sensor and the safing sensor indicate an
impact that is severe enough to require front supple-
mental restraint system protection and, based upon
the status of the passenger airbag on/off switch input
and the severity of the monitored impact, determines
what combination of seat belt tensioner and front air-
bag deployment is required for each front seating
position. When the programmed conditions are met,
the ACM sends the proper electrical signals to deploy
the seat belt tensioners and dual front airbags.The hard wired inputs and outputs for the ACM
may be diagnosed and tested using conventional
diagnostic tools and procedures. However, conven-
tional diagnostic methods will not prove conclusive in
the diagnosis of the ACM, the PCI data bus network,
or the electronic message inputs to and outputs from
the ACM. The most reliable, efficient, and accurate
means to diagnose the ACM, the PCI data bus net-
work, and the electronic message inputs to and out-
puts from the ACM requires the use of a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation.

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. Theupper 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
