DODGE RAM 2001 Service Repair Manual

Operate the power seat switch to move all three
seat motors in each direction. The seat should move
in each of the selected directions. If the power seat
adjuster fails to operate in only one direction, move
the adjuster a short distance in the opposite direction
and test again to be certain that the adjuster is not
at its travel limit. If the power seat adjuster still
fails to operate in only one direction, see Power Seat
Switch in the Diagnosis and Testing section of this
group. If the power seat adjuster fails to operate in
more than one direction, proceed as follows:
(1) Test the fuse in the power distribution center
as described in this group. If OK, go to Step 2. If not
OK, replace the faulty fuse.
(2) Remove the power seat switch from the seat.
Check for battery voltage at the fused B(+) circuit
cavity of the power seat switch wire harness connec-
tor. If OK, go to Step 3. If not OK, repair the open
circuit to the power distribution center as required.
(3) Check for continuity between the ground cir-
cuit cavity of the power seat switch wire harness con-
nector and a good ground. There should be
continuity. If OK, go to Step 4. If not OK, repair the
open circuit to ground as required.
(4) Test the power seat switch as described in this
group. If the switch tests OK, check the wire harness
for the inoperative power seat motor(s) between the
power seat switch and the motor for shorts or opens.
If the circuits check OK, replace the faulty power
seat adjuster and motors assembly. If the circuits are
not OK, repair the wire harness as required.

POWER WINDOWS
DESCRIPTION
Power windows are available as factory-installed
optional equipment on this model. The power lock
system is included on vehicles equipped with the
power window option.
OPERATION
The power window system allows each of the front
door windows to be raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. Additionally, the master switch on the
driver side door trim panel allows the driver to raise
or lower the passenger side front door window. The
power window system receives battery feed through a
circuit breaker in the junction block, only when the
ignition switch is in the On position.
The power window system includes the power win-
dow switches on each front door trim panel, the cir-
cuit breaker in the junction block, and the power
window motors inside each front door. This group
covers diagnosis and service of only the electrical
components in the power window system. For service
of mechanical components, such as the regulator, lift
plate, window tracks, or glass refer to Group 23 -
Body.
Refer to the owner's manual in the vehicle glove
box for more information on the features, use and
operation of the power window system.
DIAGNOSIS AND TESTING - POWER
WINDOWS
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out informationand location views for the various wire harness con-
nectors, splices and grounds.
ALL WINDOWS INOPERATIVE
(1) Check the circuit breaker in the junction block.
If OK, go to Step 2. If not OK, replace the faulty cir-
cuit breaker.
(2) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the driver side front door trim panel.
Unplug the wire harness connector from the switch
and bezel unit.
(3) Check for continuity between the ground cir-
cuit cavity of the switch and bezel unit wire harness
connector and a good ground. If OK, (Refer to 8 -
ELECTRICAL/POWER WINDOWS/POWER WIN-
DOW SWITCH - DIAGNOSIS AND TESTING). If not
OK, repair the circuit to ground as required.
ONE WINDOW INOPERATIVE
The window glass must be free to slide up and
down for the power window motor to function prop-
erly. If the glass is not free to move up and down, the
motor will overload and trip the integral circuit
breaker. To determine if the glass is free, disconnect
the regulator plate from the glass. Then slide the
window up and down by hand.
There is an alternate method to check if the glass
is free. Position the glass between the up and down
stops. Then, shake the glass in the door. Check that
the glass can be moved slightly from side to side,
front to rear, and up and down. Then check that the
glass is not bound tight in the tracks. If the glass is
free, proceed with the diagnosis that follows. If the
glass is not free, (Refer to 23 - BODY/DOOR -
FRONT/DOOR GLASS - REMOVAL).
(1) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the door trim panel on the side of the
BR/BEPOWER WINDOWS 8N - 23

vehicle with the inoperative window. Unplug the wire
harness connector from the switch and bezel unit.
(2) Connect the battery negative cable. Turn the
ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (run) cir-
cuit cavity in the body half of the switch and bezel
unit wire harness connector. If OK, and the inopera-
tive power window is on the driver side, go to Step 4.
If OK, and the inoperative power window is on the
passenger side, go to Step 3. If not OK, repair the
open circuit to the junction block as required.
(3) Disconnect and isolate the battery negative
cable. Check for continuity between each of the two
master window switch right up/down control circuit
cavities in the body half of the passenger side switch
and bezel unit wire harness connector and a good
ground. In each case, there should be continuity. If
OK, go to Step 4. If not OK, repair the open circuit to
the driver side switch and bezel unit as required.
(4) Test the power window switch continuity.
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - DIAGNOSIS AND
TESTING). If OK, go to Step 5. If not OK, replace
the faulty power window and lock switch and bezel
unit.
(5) Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, details
of wire harness routing and retention, connector pin-
out information and location views for the various
wire harness connectors, splices and grounds. Check
the continuity in each circuit between the inoperative
power window and lock switch and bezel unit wire
harness connector cavities and the corresponding
power window motor wire harness connector cavities.
If OK, (Refer to 8 - ELECTRICAL/POWER WIN-
DOWS/WINDOW MOTOR - DIAGNOSIS AND TEST-
ING). If not OK, repair the open circuit(s) as
required.
NOTE: The passenger side power window switch
receives the ground feed for operating the passen-
ger side power window motor through the driver
side power window switch and wire harness con-
nector.
POWER WINDOW SWITCH
DESCRIPTION
The power windows are controlled by two-way
switches integral to the power window and lock
switch and bezel unit on the trim panel of each front
door. A second power window switch in the driver
side switch and bezel unit allows the driver to control
the passenger side window. A Light-Emitting Diode(LED) in the paddle of each switch is illuminated
whenever the ignition switch is in the On position.
OPERATION
The power window switch for the driver side front
door has an Auto label on it. This switch has a sec-
ond detent position beyond the normal Down position
that provides an automatic one-touch window down
feature. This feature is controlled by an electronic
circuit and a relay that are integral to the driver side
front door power window and lock switch unit.
The power window switches control the battery
and ground feeds to the power window motors. The
passenger side power window switch receives a
ground feed through the driver side power window
switch for operating the passenger side power win-
dow motor.
The power window and lock switch and bezel unit
cannot be repaired and, if faulty or damaged, the
entire switch and bezel unit must be replaced.
DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH
The auto down feature of the driver side power
window switch is controlled by an electronic circuit
within the switch unit. The auto down circuitry is
activated when the driver side power window switch
is moved to the second detent in the Down direction.
The outputs from the auto down circuitry are carried
through the same switch pins that provide the nor-
mal down function. The auto down circuit cannot be
tested. If the driver side power window switch conti-
nuity tests are passed, but the auto down feature is
inoperative, replace the faulty driver side power win-
dow switch unit.
The Light-Emitting Diode (LED) illumination
lamps for all of the power window and lock switch
and bezel unit switch paddles receive battery current
through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in
either or both power window and lock switch and
bezel units and the power windows are inoperative,
perform the diagnosis for Power Window System in
this group. If the power windows operate, but any or
all of the LEDs are inoperative, the power window
and lock switch and bezel unit with the inoperative
LED(s) is faulty and must be replaced. For circuit
descriptions and diagrams, refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.

WINDOW MOTOR
DESCRIPTION
A permanent magnet reversible motor moves the
window regulator through an integral gearbox mech-
anism. A positive and negative battery connection to
the two motor terminals will cause the motor to
rotate in one direction. Reversing the current
through these same two connections will cause the
motor to rotate in the opposite direction.
In addition, each power window motor is equipped
with an integral self-resetting circuit breaker to pro-
tect the motor from overloads. The power window
motor and gearbox assembly cannot be repaired and,
if faulty or damaged, the entire power window regu-
lator assembly must be replaced.
DIAGNOSIS AND TESTING - WINDOW MOTOR
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds. Before you proceed withthis diagnosis, confirm proper switch operation.
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - DIAGNOSIS AND
TESTING).
(1) Disconnect and isolate the battery negative
cable. Remove the trim panel from the door with the
inoperative power window.
(2) Unplug the power window motor wire harness
connector. Apply 12 volts across the motor terminals
to check its operation in one direction. Reverse the
connections across the motor terminals to check the
operation in the other direction. Remember, if the
window is in the full up or full down position, the
motor will not operate in that direction by design. If
OK, repair the circuits from the power window motor
to the power window switch as required. If not OK,
replace the faulty motor.
(3) If the motor operates in both directions, check
the operation of the window glass and lift mechanism
through its complete up and down travel. There
should be no binding or sticking of the window glass
or lift mechanism through the entire travel range. If
not OK, (Refer to 23 - BODY/DOOR - FRONT/WIN-
DOW REGULATOR - REMOVAL).
REMOVAL
The power window motor and mechanism is inte-
gral to the power window regulator unit. If the power
window motor or mechanism is faulty or damaged,
the entire power window regulator unit must be
replaced. (Refer to 23 - BODY/DOOR - FRONT/WIN-
DOW REGULATOR - REMOVAL) for the window
regulator service procedures.

DESCRIPTION
A dual front airbag system is standard factory-in-
stalled safety equipment on this model. The airbag
system is a passive, inflatable, Supplemental
Restraint System (SRS) and vehicles with this equip-
ment can be readily identified by the ªSRS - AIR-
BAGº logo molded into the driver airbag trim cover
in the center of the steering wheel and also into the
passenger airbag door on the instrument panel above
the glove box (Fig. 1). Vehicles with the airbag sys-
tem can also be identified by the airbag indicator,which will illuminate in the instrument cluster for
about seven seconds as a bulb test each time the
ignition switch is turned to the On position.
The dual front airbag system consists of the follow-
ing major components, which are described in further
detail elsewhere in this service manual:
²Airbag Control Module- The Airbag Control
Module (ACM) is located on a mount on the floor
panel transmission tunnel, below the center of the
instrument panel.
²Airbag Indicator- The airbag indicator is inte-
gral to the ElectroMechanical Instrument Cluster
(EMIC), which is located on the instrument panel in
front of the driver.
BR/BERESTRAINTS 8O - 1

²Clockspring- The clockspring is located near
the top of the steering column, directly beneath the
steering wheel.
²Driver Airbag- The driver airbag is located in
the center of the steering wheel, beneath the driver
airbag trim cover.
²Driver Knee Blocker- The driver knee blocker
is a molded plastic structural unit secured to the
back side of and integral to the instrument panel
steering column opening cover.
²Passenger Airbag- The passenger airbag is
located on the instrument panel, beneath the passen-
ger airbag door on the instrument panel above the
glove box on the passenger side of the vehicle.
²Passenger Airbag On/Off Switch- The pas-
senger airbag on/off switch is located in a dedicated
opening in the upper right corner of the instrument
panel cluster bezel, to the right of the center panel
outlets of the climate control system.
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
The ACM and the EMIC each contain a central
processing unit and programming that allow them to
communicate with each other using the Chrysler Col-
lision Detection (CCD) data bus network. This
method of communication is used for control of the
airbag indicator on all models. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/
COMMUNICATION - DESCRIPTION).
Hard wired circuitry connects the airbag system
components to each other through the electrical sys-
tem of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system, and to the air-
bag system components through the use of a combi-
nation of soldered splices, splice block connectors,and many different types of wire harness terminal
connectors and insulators. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, further details on wire harness routing
and retention, as well as pin-out and location views
for the various wire harness connectors, splices and
grounds.
OPERATION
The airbag system is referred to as a supplemental
restraint system because it was designed and is
intended to enhance the protection for the front seat
occupants of the vehicleonlywhen used in conjunc-
tion with the seat belts. It is referred to as a passive
system because the vehicle occupants are not
required to do anything to make it work. The pri-
mary passenger restraints in this or any other vehi-
cle are the standard equipment factory-installed seat
belts. Seat belts are referred to as an active restraint
because the vehicle occupants are required to physi-
cally fasten and properly adjust these restraints in
order to benefit from them. The vehicle occupants
must be wearing their seat belts in order to obtain
the maximum safety benefit from the factory-in-
stalled airbag system.
The airbag system electrical circuits are continu-
ously monitored and controlled by a microprocessor
and software contained within the Airbag Control
Module (ACM). An airbag indicator in the ElectroMe-
chanical Instrument Cluster (EMIC) lights for about
seven seconds as a bulb test each time the ignition
switch is turned to the On or Start positions. Follow-
ing the bulb test, the airbag indicator is turned on or
off by the ACM to indicate the status of the airbag
system. If the airbag indicator comes on at any time
other than during the bulb test, it indicates that
there is a problem in the airbag system electrical cir-
cuits. Such a problem may cause the airbags not to
deploy when required, or to deploy when not
required.
The clockspring on the top of the steering column
allows a continuous electrical circuit to be main-
tained between the stationary steering column and
the driver airbag inflator, which rotates with the
steering wheel. The passenger airbag on/off switch
allows the passenger side airbag to be disabled when
circumstances necessitate that a child, or an adult
with certain medical conditions be placed in the front
passenger seating position. Refer to the owner's man-
ual in the vehicle glove box for specific recommenda-
tions concerning the specific circumstances where the
passenger airbag on/off switch should be used to dis-
able the passenger airbag.

8O - 2 RESTRAINTSBR/BE
RESTRAINTS (Continued)

Deployment of the airbags depends upon the angle
and severity of the impact. The airbag system is
designed to deploy upon a frontal impact within a
thirty degree angle from either side of the vehicle
center line. Deployment is not based upon vehicle
speed; rather, deployment is based upon the rate of
deceleration as measured by the forces of gravity (G
force) upon the airbag system impact sensor, which is
integral to the ACM. When a frontal impact is severe
enough, the microprocessor in the ACM signals the
inflator units of both airbag modules to deploy the
airbags. During a frontal vehicle impact, the knee
blockers work in concert with properly fastened and
adjusted seat belts to restrain both the driver and
the front seat passenger in the proper position for an
airbag deployment. The knee blockers also absorb
and distribute the crash energy from the driver and
the front seat passenger to the structure of the
instrument panel.
Typically, the driver and front seat passenger recall
more about the events preceding and following a col-
lision than they have of the airbag deployment itself.
This is because the airbag deployment and deflation
occur so rapidly. In a typical 48 kilometer-per-hour
(30 mile-per-hour) barrier impact, from the moment
of impact until both airbags are fully inflated takes
about 40 milliseconds. Within one to two seconds
from the moment of impact, both airbags are almost
entirely deflated. The times cited for these events are
approximations, which apply only to a barrier impact
at the given speed. Actual times will vary somewhat,
depending upon the vehicle speed, impact angle,
severity of the impact, and the type of collision.
When the ACM monitors a problem in any of the
airbag system circuits or components, it stores a
fault code or Diagnostic Trouble Code (DTC) in its
memory circuit and sends an electronic message to
the EMIC to turn on the airbag indicator. Proper
testing of the airbag system components, the
Chrysler Collision Detection (CCD) data bus, the
data bus message inputs to and outputs from the
EMIC or the ACM, as well as the retrieval or erasure
of a DTC from the ACM requires the use of a
DRBIIItscan tool. Refer to the appropriate diagnos-
tic information.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of all of the factory-installed passenger restraints,
including the airbag system.

DIAGNOSIS AND TESTING - AIRBAG SYSTEM
Proper diagnosis and testing of the airbag system
components, the PCI data bus, the data bus message
inputs to and outputs from the ElectroMechanical
Instrument Cluster (EMIC) or the Airbag Control
Module (ACM), as well as the retrieval or erasure of
a Diagnostic Trouble Code (DTC) from the ACM
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
STANDARD PROCEDURE - HANDLING
NON-DEPLOYED AIRBAGS
At no time should any source of electricity be per-
mitted near the inflator on the back of a non-de-
ployed airbag. When carrying a non-deployed airbag,
the trim cover or airbag cushion side of the unit
should be pointed away from the body to minimize
injury in the event of an accidental deployment. If
the airbag unit is placed on a bench or any other sur-
face, the trim cover or airbag cushion side of the unit
should be face up to minimize movement in the event
of an accidental deployment. In addition, the airbag
system should be disarmed whenever any steering
wheel, steering column, or instrument panel compo-
nents require diagnosis or service. Failure to observe
this warning could result in accidental airbag deploy-
ment and possible personal injury.
All damaged or faulty and non-deployed driver or
passenger airbags which are replaced on vehicles are
to be returned. If an airbag unit is faulty or damaged
and non-deployed, refer to the parts return list in the
current DaimlerChrysler Corporation Warranty Poli-
cies and Procedures manual for the proper handling
and disposal procedures.
AIRBAG STORAGE
An airbag must be stored in its original, special
container until it is used for service. Also, it must be
stored in a clean, dry environment; away from
sources of extreme heat, sparks, and high electricalenergy. Always place or store any airbag on a surface
with its trim cover or airbag cushion side facing up,
to minimize movement in case of an accidental
deployment.
STANDARD PROCEDURE - SERVICE AFTER AN
AIRBAG DEPLOYMENT
Any vehicle which is to be returned to use follow-
ing an airbag deployment, must have both airbags,
the driver airbag trim cover, the clockspring, and the
steering column assembly replaced. These compo-
nents are not intended for reuse and will be damaged
or weakened as a result of an airbag deployment,
which may or may not be obvious during a visual
inspection. Other vehicle components should be
closely inspected, but are to be replaced only as
required by the extent of the visible damage
incurred.
CLEANUP PROCEDURE
Following an airbag deployment, the vehicle inte-
rior will contain a powdery residue. This residue con-
sists primarily of harmless particulate by-products of
the small pyrotechnic charge used to initiate the pro-
pellant used to deploy the airbags. However, this res-
idue may also contain traces of sodium hydroxide
powder, a chemical by-product of the propellant
material that is used to generate the nitrogen gas
that inflates the airbag. Since sodium hydroxide pow-

WARNING: IF YOU EXPERIENCE SKIN IRRITATION
DURING CLEANUP, RUN COOL WATER OVER THE
AFFECTED AREA. ALSO, IF YOU EXPERIENCE
IRRITATION OF THE NOSE OR THROAT, EXIT THE
VEHICLE FOR FRESH AIR UNTIL THE IRRITATION
CEASES. IF IRRITATION CONTINUES, SEE A PHYSI-
CIAN.
Begin the cleanup by removing both airbags from
the vehicle. Refer to the appropriate service removal
procedures. Place the deployed airbags in your vehic-
ular scrap pile.
Next, use a vacuum cleaner to remove any residual
powder from the vehicle interior. Clean from outside
the vehicle and work your way inside, so that you
avoid kneeling or sitting on a non-cleaned area. Be
certain to vacuum the heater and air conditioning
outlets as well (Fig. 3). Run the heater and air con-
ditioner blower on the lowest speed setting and vac-
uum any powder expelled from the outlets. You may
need to vacuum the interior of the vehicle a second
time to recover all of the powder.
STANDARD PROCEDURE - VERIFICATION TEST
The following procedure should be performed using
a DRBIIItscan tool to verify proper airbag system
operation following the service or replacement of any
airbag system component.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAGSYSTEM. FAILURE TO TAKE THE PROPER PRECAU-
TIONS 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 airbag component removal and installa-
tion 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. 4).
(3) Turn the ignition switch to the On position and
exit the vehicle with the DRBIIIt.
(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.
