Refer to Group 25, for further information and use-
age of the DRB scan tool and a more complete list of
Diagnostic Trouble Code.
SPEED CONTROL SLOWS DOWN BY ITSELF
Test vehicle speed sensor, refer to group 8E. If sen-
sor fails replace sensor, if it passes perform the fol-
lowing test:
(1) Perform the speed control switch test on the
DECEL switch, if it fails replace switch.
(2) If the switch passes, conduct the vacuum sup-
ply test.
(3) If it passes, conduct the servo vacuum test. If it
fails replace servo.
(4) If continuity, replace the PCM.
SPEED CONTROL ELECTRICAL TEST
Electronic speed control systems may be tested
using two different methods. One involves use of a
DRB. If this test method is desired, refer to the Pow-
ertrain Diagnostic Test Procedures for charging and
speed control system manual.The other test method uses a volt/ohm meter. The
volt/ohm meter method is described in the following
tests.
If any information is needed concerning wiring,
refer to Group 8W, Wiring Diagrams (Fig. 2).
CAUTION: When test probing for voltage or conti-
nuity at electrical connectors, care must be taken
not to damage connector, terminals, or seals. If
these components are damaged, intermittent or
complete system failure may occur.
When electrical connections are removed, corrosion
should be removed from electrical terminals and a
light coating of Mopar Multi-Purpose Grease, or
equivalent, applied. Inspect connectors for damage
terminals.
A poor connection can cause a complete or inter-
mittent malfunction and is also the only connection
in the circuit, that can not be tested. For this reason,
a loose connection may be misdiagnosed as a compo-
nent malfunction.

GENERAL INFORMATION
INTRODUCTION
The turn signals are actuated with a lever on the
left side of the steering column just ahead of the
steering wheel. The signals are automatically turned
off by a canceling cam (two lobes molded to the clock-
spring mechanism). The cam comes in contact with
the cancel actuator on the turn signal (multi-func-
tion) switch assembly. Either cam lobe, pushing on
the cancel actuator, returns the switch to the OFF
position.
Lane change signaling is actuated by applying par-
tial turn signal stalk movement toward the direction
desired until the indicator lamps flashes in the
instrument cluster. When the switch stalk is released
the stalk will spring back into the neutral position
turning OFF the turn signal.
With the ignition switch ON and the turn signal
switch stalk actuated left or right, current flows
through the:
²Combination flasher
²Multi-function switch
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 0.5 mile with the turn sig-
nal ON.
COMBINATION FLASHER
The Turn Signal/Hazard Warning Flasher is a
module providing the vehicle with turn signal and
hazard warning functions and has been designed
with internal relays to take advantage of low current
switching requirements in the vehicle. It is plugged
into the Junction Block at position 4 (Fig. 1), where
all wiring associated with its operation is terminated.The Junction Block is adjacent to and left of the
steering column of the vehicle.
To gain access to the flasher, remove the lower
steering column cover and knee blocker. Refer to
Group 8E, Instrument Panel and Systems for
removal procedures.
DESCRIPTION AND OPERATION
COMBINATION FLASHER FUNCTION
The Turn Signal/Hazard Warning Flasher is a
module providing turn signal, hazard warning func-
tions and has been designed with internal relays to
Fig. 1 Combination Flasher Location
NSTURN SIGNAL AND FLASHERS 8J - 1
Page 430 of 1938

take advantage of low current switching require-
ments in the vehicle. It is plugged into the Junction
Block at positions 4 (Fig. 1) where all wiring associ-
ated with its operation is terminated. The Junction
Block is adjacent to and left of the steering column of
the vehicle.
To gain access to the device, remove the lower
steering column cover and knee blocker, refer to
Group 8E, Instrument Panel and Systems.
The combination flasher may be operated in its
hazard warning mode either with or without the igni-
tion circuit being active. However, in order to operate
in the turn signal mode, the ignition circuit must be
completed to the module.
While the combination flasher is idle, there is no
current drawn through the module. The device does
not become active until a signal ground circuit is
supplied to either of the turn signal inputs or the
hazard warning input.
Typical flash rate for the flasher is 90 flashes per
minute.
When a lamp is burnt out for a given side of the
vehicle or a wire is open to a lamp, the flash rate will
increase to 180 flashes per minute when in the turn
signal mode. When in the hazard warning signal
mode the flash rate remains at 90 flashes per
minute.
Turn signal inputs that actuate the flasher are low
current grounds, each drawing a maximum of 300
mA., and are provided to the flasher through the
Junction Block from the multi-function switch that is
mounted to the steering column. The hazard warning
signal input is a low current ground drawing a max-
imum of 600 mA. through the multi-function switch.
COMBINATION FLASHER / DAYTIME RUNNING
LAMPS (DRL) MODULE
The Combination Flasher/DRL is a module provid-
ing turn signal, hazard warning, and daytime run-
ning light functions, and has been designed with
internal relays to take advantage of low current
switching requirements in the vehicle. It is plugged
into the junction block at positions 3 AND 4 (Fig. 2)
where all wiring associated with its operation is ter-
minated. The Junction Block is adjacent to and left of
the steering column of the vehicle.
To gain access to the device, remove the lower
steering column cover and knee blocker, refer to
Group 8E, Instrument Panel and Gauges.
The combination flasher/DRL may be operated in
its hazard warning mode either with or without the
ignition circuit being active. However, in order to
operate in the turn signal mode or the DRL mode,
the ignition circuit must be completed to the module.
While the combination flasher portion is idle, there
is no current drawn through the module. The devicedoes not become active in the turn signal or hazard
warning modes until a signal ground circuit is sup-
plied to either of the turn signal inputs or the hazard
warning input. With the ignition OFF, there is no
current drawn through the module.
While the ignition is ON, the front turn signal fil-
aments are illuminated steadily thus providing the
DRL function. The DRL function may be inhibited by
applying a signal ground input from either the park
brake circuit or the headlamp relay activation circuit.
Typical flash rate for the flasher is 90 flashes per
minute.
When a lamp is burnt out for a given side of the
vehicle or a wire is open to a lamp, the flash rate will
increase to 180 flashes per minute when in the turn
signal mode. When in the hazard warning signal
mode the flash rate remains at 90 flashes per
minute.
Turn signal inputs that actuate the flasher are low
current grounds, each could draw a maximum of 300
mA., and are provided to the flasher through the
Junction Block from the multi-function switch that is
mounted to the steering column. The hazard warning
signal input is a low current ground that could draw
a maximum of 600 mA. through the multi-function
switch.
DIAGNOSIS AND TESTING
TURN SIGNAL MULTI-FUNCTION SWITCH
To test turn signal, headlamp beam select and opti-
cal horn portion of the multi-function switch:
(1) Remove the multi-function switch, refer to
removal procedures.
(2) Using an ohmmeter check continuity reading
between multi-function switch pins. Refer to (Fig. 3)

COMBINATION FLASHER WITH / WITHOUT
DAYTIME RUNNING LAMPS MODULEÐCIRCUIT
DIAGNOSTICS
The battery input (Pin 1), is brought into the Junction
Block through the Electrical Distribution Wiring (EDW)
harness (Fig. 4). It originates under the hood in thePower Distribution Center (PDC) through a 20 ampere
fuse at position 10 (9th position from the upper end) and
labeled HAZARD. This circuit (L09) is the only power
feed to the combination-flasher/DRL.
The ignition input of Pin 6 (refer to Junction Block
Terminal Call-Out and Junction Block Terminal Call-Out
with DRL tables) only senses that the ignition circuit is
ON and does not supply current to the module in a way
that would power the system. This RUN/START circuit is
brought into the junction block to a 10 ampere fuse
labeled TS BU LMP at the bottom right side. The circuit
designation out of the fuse is A22D. This circuit feeds the
combo-flasher and the following systems with Ignition
voltage if the vehicle is so equipped:
²Back-Up Lamps
²Electrochromic Inside Rear view Mirror
²A/C Control Head
²Mini-Trip Computer
²ABS Module
²Front Blower Relay Coil
²Rear Blower Relay Coil
²AWD Solenoids
²Rear Window Defogger (EBL) Relay Coil
The ignition input to the combo-flasher will draw
typically 5 mA of current while active.
For diagnostic test procedures, refer to Combina-
tion Flasher Diagnosis tables.
