Dodge Sprinter. Manual — part 79
INSTALLATION
The following procedure is for replacement of a
faulty or damaged side curtain airbag. If the airbag
is faulty or damaged, but not deployed, review the
recommended procedures for handling non-deployed
supplemental restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - HAN-
DLING
NON-DEPLOYED
SUPPLEMENTAL
RESTRAINTS). If the side curtain airbag has been
deployed, review the recommended procedures for
service after a supplemental restraint deployment
before removing the airbag from the vehicle. (Refer to
8 - ELECTRICAL/RESTRAINTS - STANDARD PRO-
CEDURE - SERVICE AFTER A SUPPLEMENTAL
RESTRAINT DEPLOYMENT).
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental
restraint
system
before
attempting
any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, when
removing a deployed airbag, rubber gloves, eye
protection, and a long-sleeved shirt should be
worn. There may be deposits on the airbag unit and
other interior surfaces. In large doses, these depos-
its may cause irritation to the skin and eyes.
WARNING: To avoid personal injury or death, use
extreme care to prevent any foreign material from
entering the side curtain airbag, or becoming
entrapped between the side curtain airbag cushion
and
the
roof
rail
garnish
molding.
Failure
to
observe this warning could result in occupant inju-
ries upon airbag deployment.
(1) Position the side curtain airbag into the vehicle
as a unit.
(2) Engage the lug that secures the side curtain
airbag bracket into the bore in the roof side rail (Fig.
50).
(3) Install and tighten the screw that secures the
rear of the side curtain airbag to the B-pillar (Fig.
48). Tighten the screw to 23 N·m (17 ft. lbs.).
(4) Install and tighten the screw that secures the
front of the side curtain airbag to the A-pillar.
Tighten the screw to 9 N·m (80 in. lbs.).
(5) Install and tighten the screw that secures the
side curtain airbag front tether retainer to the base
of the A-pillar near the belt line (Fig. 47). Tighten
the screw to 5 N·m (44 in. lbs.).
(6) Install a new tie wrap to secure the side cur-
tain airbag pigtail wire to the inside of the B-pillar
(Fig. 46).
(7) Reconnect the pigtail wire connector for the
side curtain airbag to the vehicle wire harness con-
nector on the B-pillar. Be certain the connector is
fully engaged and latched.
(8) Reinstall the trim onto the A-pillar that con-
ceals the side curtain airbag front tether (Fig. 45).

(9) Reinstall the grab handle onto the headliner.
(Refer to 23 - BODY/INTERIOR/ASSIST HANDLE -
INSTALLATION).
(10) Reinstall the trim onto the inside of the B-pil-
lar. (Refer to 23 - BODY/INTERIOR/B-PILLAR TRIM
- INSTALLATION).
(11) Reinstall the pinch welt to the front door
opening (Fig. 44).
(12) Do not reconnect the battery negative cable at
this time. The supplemental restraint system verifi-
cation test procedure should be performed following
service of any supplemental restraint system compo-
nent. (Refer to 8 - ELECTRICAL/RESTRAINTS -
STANDARD PROCEDURE - VERIFICATION TEST).
SIDE IMPACT SENSOR
DESCRIPTION
On vehicles equipped with the optional side curtain
airbags, two side impact sensors are used, one each
for the left and right sides of the vehicle (Fig. 51).
These sensors are mounted remotely from the bi-di-
rectional safing sensor that is internal to the Airbag
Control Module (ACM). The side impact sensors are
each secured with two screws to the forward vertical
surface of the right and left front door step wells and
concealed behind the step well trim paneling within
the passenger compartment.
The impact sensor housing has an integral connec-
tor receptacle and two integral mounting flanges, one
at the top and one at the bottom. An arrow on the
sensor housing provides a visual verification of the
proper orientation of the unit, and should always be
pointed toward the outboard side of the vehicle. A
cavity in the center of the molded plastic impact sen-
sor housing contains the electronic circuitry of the
sensor, which includes an electronic communication
chip and an electronic impact sensor. Potting mate-
rial fills the cavity to seal and protect the internal
electronic circuitry and components. The side impact
sensors are each connected to the vehicle electrical
system through a dedicated take out and connector of
the vehicle wire harness.
The side impact sensors cannot be repaired or
adjusted and, if damaged or faulty, they must be
replaced.
OPERATION
The side impact sensors are electronic accelerome-
ters that sense the rate of vehicle deceleration, which
provides verification of the direction and severity of
an impact. Each sensor also contains an electronic
communication chip that allows the unit to commu-
nicate the sensor status as well as sensor fault infor-
mation to the microprocessor in the Airbag Control
Module (ACM). The ACM microprocessor continu-
ously monitors all of the passive restraint system
electrical circuits to determine the system readiness.
If the ACM detects a monitored system fault, it sets
a Diagnostic Trouble Code (DTC) and controls the
airbag indicator operation accordingly.
The impact sensors each receive battery current
and ground through dedicated left and right sensor
plus and minus circuits from the ACM. The impact
sensors and the ACM communicate by modulating
the voltage in the sensor plus circuit. The hard wired
circuits between the side impact sensors and the
ACM may be diagnosed and tested using conven-
tional diagnostic tools and procedures. However, con-
ventional
diagnostic
methods
will
not
prove
conclusive in the diagnosis of the ACM or the impact
sensors. The most reliable, efficient, and accurate
means to diagnose the impact sensors, the ACM, and
the electronic message communication between the
sensors and the ACM requires the use of a diagnostic
scan tool. Refer to the appropriate diagnostic infor-
mation.

REMOVAL
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental
restraint
system
before
attempting
any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, never
strike or drop the side impact sensor, as it can
damage the impact sensor or affect its calibration.
The side impact sensor enables the system to
deploy the side curtain airbags. If an impact sensor
is accidentally dropped during service, the sensor
must be scrapped and replaced with a new unit.
Failure to observe this warning could result in acci-
dental,
incomplete,
or
improper
supplemental
restraint deployment.
(1) Disconnect and isolate the battery negative
cable. Wait two minutes for the system capacitor to
discharge before further service.
(2) Remove the trim paneling from the interior of
the front door step well. (Refer to 23 - BODY/INTE-
RIOR/STEPWELL SCUFF PADS - REMOVAL).
(3) Disconnect the vehicle wire harness connector
from the side impact sensor connector receptacle
(Fig. 52).
(4) Remove the two screws that secure the side
impact sensor to the forward vertical surface of the
step well.
(5) Remove the side impact sensor from the step
well.
