TURN SIGNALS
TURN SIGNAL RELAY
In the RUN position, the ignition switch connects
circuit A1 from fuse 6 in the Power Distribution Cen-
ter (PDC) to circuit A21. Circuit A21 connects to the
turn signal relay.
Circuit L9 from fuse 4 in the PDC supplies battery
voltage to the relay. Circuit Z1 provides ground for
the relay.
Circuit L5 from the relay connects to the multi-
function switch to supply power to the turn signals.
The multi-function switch supplies voltage to the
turn signals and side marker lamps on circuits L60
and L61.
Circuit L12 from the relay connects to the multi-
function switch and the hazard flasher relay.
TURN SIGNALS
When the operator selects the right turn signal, the
multi-function switch connects power from circuit L5
to circuit L60. Circuit L60 feeds the right front and
right rear turn signal lamp. Circuit L60 also splices
to power the right turn signal indicator lamp on the
instrument cluster.
When the operator selects the right turn signal, the
multi-function switch connects power from circuit L5
to circuit L61. Circuit L61 feeds the left front and
left rear turn signal lamp. Circuit L61 also splices to
power the left turn signal indicator lamp on the in-
strument cluster.
Circuit Z1 provides ground for the turn signal
lamps.
HELPFUL INFORMATION
²The turn signal lamps are the same lamps used
for the hazard flasher.
²Check fuse 6 in the PDC.
HAZARD FLASHERS
When the operator selects the hazard flashers, the
multi-function switch connects circuit L12 from the
hazard flasher relay to circuits L60 and L61.
Circuit L60 feeds the right front and right rear
turn signal lamp. Circuit L60 also splices to power
the right turn signal indicator lamp on the instru-
ment cluster.
Circuit L61 feeds the left front and left rear turn
signal lamp. Circuit L61 also splices to power the left
turn signal indicator lamp on the instrument cluster.
Circuit Z1 provides ground for the hazard flasher
lamps.

TRAILER TOW
TRAILER TOW
The factory installed trailer tow system in this ve-
hicle uses three relays and a circuit breaker along
with the trailer tow wiring connector located below
the rear bumper.
Battery voltage for the trailer tow circuit breaker
and relays is supplied on circuit A11. This circuit is
HOT at all times and connects to the power accessory
tap in the fuse block. An in line 10 amp circuit pro-
tected breaker protects circuit A11 and the trailer
tow circuits. The trailer tow circuit breaker is located
in the left rear quarter panel.
STOP LAMP RELAY
Power for the coil side of the stop lamp relay is
supplied by circuit L50. This circuit connects to the
stop lamps. Ground for the coil side is supplied on
circuit Z1.
When the operator depresses the brake pedal, volt-
age flows through the coil of the relay to ground
causing the contacts in the relay to close connecting
circuits A11 and 95.
Circuit 95 connects to the left and right turn signal
relays. Voltage flows through the closed contacts in
the relays to the trailer tow connector.
RIGHT TURN RELAY
Power for the coil side of the right turn relay is
supplied by circuit L60. This circuit connects to the
right side turn signal lamps. Ground for the coil side
of the relay is supplied on circuit Z1.
When the operator turns the right turn signal ON,
power flows through the coil in the relay to ground
causing the contacts in the relay to switch from there
normally CLOSED position to connect circuits 94 and
L60.
Circuit 94 is the feed for the contact side of the re-
lay. Circuit L60 connects from the relay to the trailer
tow connector.
Circuit 94 is fed power through the normally
CLOSED side of the stop lamp relay and circuit A11.
The A11 circuit is HOT at all times and protected by
a 10 amp circuit breaker located in the left rear
quarter panel.
LEFT TURN RELAY
Power for the coil side of the left turn relay is sup-
plied by circuit L61. This circuit connects to the left
side turn signal lamps. Ground for the coil side of the
relay is supplied on circuit Z1.
When the operator turns the left turn signal ON,
power flows through the coil in the relay to ground
causing the contacts in the relay to switch from there
normally CLOSED position to connect circuits 94 and
L61.
Circuit 94 is the feed for the contact side of the re-
lay. Circuit L61 connects from the relay to the trailer
tow connector.
Circuit 94 is fed power through the normally
CLOSED side of the stop lamp relay and circuit A11.

Battery voltage for the power seat system is sup-
plied by circuit A11 from fuse 1 in the fuse block. Cir-
cuit A11 is HOT at all times and supplies battery
voltage to the power seat switch.
A BUS bar internal to the power seat switch con-
nects the power from circuit A11 to the switches.
Grounding for the seat system is supplied on circuit

ranges. Third gear ratio is 1:1. A separate planetary
gear set provides overdrive operation in fourth gear.
TRANSMISSION RANGES AND SHIFT LEVER
POSITIONS
The AW-4 transmission has six ranges and shift le-
ver positions. Park, Reverse and Neutral are conven-
tional and mechanically operated. The 1-2, 3 and D
ranges provide electronically controlled shifting.
The 1-2 position provides first and second gear
only. The 3 position provides first, second and third
gear.
The D range provides first through fourth gear.
Overdrive fourth gear range is available only when
the shift lever is in D position (Fig. 2).
TRANSMISSION IDENTIFICATION
The transmission I.D. plate is attached to the case
(Fig. 3). The plate contains the transmission serial
and model numbers. Refer to the information on this
plate when ordering service parts.
RECOMMENDED FLUID AND CAPACITY
Recommended and preferred fluid for the AW-4
transmission is Mopar Dexron IIE/Mercon.
Mopar Dexron II can be used but only in emer-
gency situations where Mercon fluid is not available.
Approximate refill capacity for the AW-4 is 8.0 li-
ters (16.9 pints or 8.45 quarts).
COMPONENTS AND OPERATION
ELECTRONIC CONTROLS
The AW-4 is electronically controlled in 1, 2, 3 and
D ranges. Controls consist of the transmission control
module (TCM), valve body solenoids and various sen-
sors. The sensors monitor vehicle speed, throttle
opening, shift lever position and brake pedal applica-
tion.
TRANSMISSION CONTROL MODULE (TCM)
The module determines shift and converter clutch
engagement timing based on signals from sensors.
The valve body solenoids are activated, or deacti-
vated accordingly.
The TCM has a self diagnostic program. Compo-
nent and circuitry malfunctions can be diagnosed
with the DRB scan tool. Once a malfunction is noted
and stored in control module memory, it is retained
even after the problem has been corrected. To cancel
a stored malfunction, disconnect and reconnect the
9Trans.9fuse in the module harness.
TRANSMISSION VALVE BODY SOLENOIDS
The solenoids are mounted on the valve body and
operated by the TCM. The solenoids control operation
of the converter clutch and shift valves in response to
input signals from the module.
SENSORS
Sensors include:
²throttle position sensor (TPS)
²transmission speed sensor
²vehicle speed sensor
²park/neutral position switch
²brake switch
The throttle position sensor is mounted on the
throttle body. It electronically determines throttle po-
sition and relays this information to the transmission
control module to determine shift points and con-
verter clutch engagement.
