2003 DODGE RAM ECU

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.

AIRBAG CONTROL MODULE (Continued)

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

CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two
screws onto the multi-function switch mounting
housing near the top of the steering column behind
the steering wheel (Fig. 17). The clockspring consists
of a flat, round molded plastic case with a stubby tail
that hangs below the steering column (Fig. 18). The
tail contains two connector receptacles that face
toward the instrument panel. Within the plastic case
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, an engagement
dowel with a yellow rubber boot, a short pigtail wire
with connector, and two connector receptacles that
face toward the steering wheel.
The lower surface of the rotor hub has a molded
plastic turn signal cancel cam with two lobes that is
keyed to the rotor and is secured there with four
integral snap features. Within the plastic case and
wound around the rotor spool is a long ribbon-like
tape that consists of several 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 wire
and connector receptacles on the hub of the clock-
spring rotor that face the steering wheel.Service replacement clocksprings are shipped pre-
centered and with a molded plastic 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 locking pin secures the centered clock-
spring rotor to the clockspring case during shipment,
but the locking pin must be removed from the clock-
spring after it is installed on the steering column.
(Refer to 8 - ELECTRICAL/RESTRAINTS/CLOCK-
SPRING - STANDARD PROCEDURE - CLOCK-
SPRING CENTERING).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mounted
on or in the rotating steering wheel. On this model
the rotating electrical components include the driver
airbag, the horn switch, the speed control switches,
and the remote radio switches, if the vehicle is so
equipped. The clockspring case is positioned and
secured to the multi-function switch mounting hous-
ing near the top of the steering column. The connec-
tor receptacles on the tail of the fixed clockspring
case connect the clockspring to the vehicle electrical
system through two take outs with connectors from
the instrument panel wire harness.
The clockspring rotor is movable and is keyed by
an engagement dowel that is molded onto the rotor
hub between two fins that are cast into the lower
surface of the steering wheel armature. A yellow rub-
