SPEED CONTROL SERVO-PCM OUTPUT
DESCRIPTION
The servo unit consists of a solenoid valve body,
and a vacuum chamber. The solenoid valve body con-
tains three solenoids:
²Vacuum
²Vent
²Dump
The vacuum chamber contains a diaphragm with a
cable attached to control the throttle linkage.
OPERATION
The PCM controls the solenoid valve body. The
solenoid valve body controls the application and
release of vacuum to the diaphragm of the vacuum
servo. The servo unit cannot be repaired and is ser-
viced only as a complete assembly.
Power is supplied to the servo's by the PCM
through the brake switch. The PCM controls the
ground path for the vacuum and vent solenoids.
The dump solenoid is energized anytime it receives
power. If power to the dump solenoid is interrupted,
the solenoid dumps vacuum in the servo. This pro-
vides a safety backup to the vent and vacuum sole-
noids.
The vacuum and vent solenoids must be grounded
at the PCM to operate. When the PCM grounds the
vacuum servo solenoid, the solenoid allows vacuum
to enter the servo and pull open the throttle plate
using the cable. When the PCM breaks the ground,
the solenoid closes and no more vacuum is allowed to
enter the servo. The PCM also operates the vent sole-
noid via ground. The vent solenoid opens and closes a
passage to bleed or hold vacuum in the servo as
required.
The PCM duty cycles the vacuum and vent sole-
noids to maintain the set speed, or to accelerate and
decelerate the vehicle. To increase throttle opening,
the PCM grounds the vacuum and vent solenoids. To
decrease throttle opening, the PCM removes the
grounds from the vacuum and vent solenoids. When
the brake is released, if vehicle speed exceeds 25
mph to resume, 30 mph to set, and the RES/ACCEL
switch has been depressed, ground for the vent and
vacuum circuits is restored.
SPEED CONTROL SWITCHESÐPCM INPUT
Description
There are two separate switch pods that operate
the speed control system. The steering-wheel-
mounted switches use multiplexed circuits to provide
inputs to the PCM for ON, OFF, RESUME, ACCEL-
ERATE, SET, DECEL and CANCEL modes. Refer tothe owner's manual for more information on speed
control switch functions and setting procedures.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
Operation
When speed control is selected by depressing the
ON, OFF switch, the PCM allows a set speed to be
stored in RAM for speed control. To store a set speed,
depress the SET switch while the vehicle is moving
at a speed between 25 and 85 mph. In order for the
speed control to engage, the brakes cannot be
applied, nor can the gear selector be indicating the
transmission is in Park or Neutral.
Once the speed control has been disengaged,
depressing the ACCEL switch restores the vehicle to
the target speed that was stored in the PCM's RAM.
NOTE: Depressing the OFF switch will erase the
set speed stored in the PCM's RAM.
If, while the speed control is engaged, the driver
wishes to increase vehicle speed, the PCM is pro-
grammed for an acceleration feature. With the
ACCEL switch held closed, the vehicle accelerates
slowly to the desired speed. The new target speed is
stored in the RAM when the ACCEL switch is
released. The PCM also has a ªtap-upº feature in
which vehicle speed increases at a rate of approxi-
mately 2 mph for each momentary switch activation
of the ACCEL switch.
The PCM also provides a means to decelerate with-
out disengaging speed control. To decelerate from an
existing recorded target speed, depress and hold the
COAST switch until the desired speed is reached.
Then release the switch. The ON, OFF switch oper-
ates two components: the PCM's ON, OFF input, and
the battery voltage to the brake switch, which powers
the speed control servo.
Multiplexing
The PCM sends out 5 volts through a fixed resistor
and monitors the voltage change between the fixed
resistor and the switches. If none of the switches are
depressed, the PCM will measure 5 volts at the sen-
sor point (open circuit). If a switch with no resistor is
closed, the PCM will measure 0 volts (grounded cir-
cuit). Now, if a resistor is added to a switch, then the
PCM will measure some voltage proportional to the
size of the resistor. By adding a different resistor to
each switch, the PCM will see a different voltage
depending on which switch is pushed.

The integrated switch assembly is mounted to the
left hand side of the steering column. When the
driver wishes to signal his intentions to change direc-
tion of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the
system is deactivated automatically. As the steering
wheel returns to the straight ahead position, a can-
celing cam molded to the clockspring mechanism
comes in contact with the cancel actuator on the turn
signal multi-function switch assembly. The cam lobe,
pushing on the cancel actuator, returns the switch to
the off position.
If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this
position the signal lamps flash as described above,
but the switch returns to the OFF position as soon as
the lever is released.
When the system is activated, one of two indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
DESCRIPTION AND OPERATION
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a push
button located in the muti-function switch (Fig. 1) on
the top of the steering column between the steering
wheel and the instrument panel. The hazard switch
is identified with a double triangle on front of the
button.
HEADLAMP SWITCH
The headlamp switch is part of the Multi-Function
Switch (Fig. 1). Refer to Multi-Function Switch Diag-
nosis and Testing, Turn Signal and Hazard Warning
Flasher Diagnosis table in this section.
COMBINATION FLASHER
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo- flasher con-
trols the flashing of the hazard warning system and
the turn signal system. An inoperative bulb or incom-
plete turn signal circuit will cause the flasher rate to
double.
The combo-flasher is located on the back of the
multi-function switch (Fig. 2). The combo-flasher is
black in color and has a dampener material wrapped
on it.

The windshield wipers will only operate with the
ignition switch in the ACCESSORY or IGNITION
RUN position. The wiper circuit is protected against
over loads by a fuse in the fuse block and a circuit
breaker within the wiper motor. This protects the cir-
cuitry of the wiper system and the vehicle. The wiper
motor has permanent magnet fields.
The intermittent wiper system, in addition to low
and high speed, has a delay mode and a pulse wipe
mode. The delay mode has a range of 1 to 15 seconds.
Pulse wipe is accomplished by momentarily moving
the stalk lever into the WASH position while the
wiper switch is in either OFF or DELAY position.
The wiper blades then sweep once or twice and
return to the previous wiper switch mode, OFF or
DELAY.The intermittent wiper function is integral to the
wiper switch. All electronics and relay are inside the
switch assembly.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.
The wiper switch also includes the MIST feature
which provides a single wipe when actuated.
DESCRIPTION AND OPERATION
WIPER BLADES
Wiper blades, exposed to the weather for a long
period of time, tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is suggested to
remove the accumulation of salt and road film. The
wiper blades, arms, and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the blades continue to
streak or smear, they should be replaced. The right
and left wipers are different blade lengths. The
driver side length is 550 mm and the passenger side
length is 475 mm. The blades should not be inter-
changed.
