8E - 2 INSTRUMENT PANEL AND SYSTEMSPL

On most vehicles another resistor has been added
to the at rest circuit causing the PCM to never see 5
volts. This was done for diagnostic purposes. If the
switch circuit should open (bad connection) then the
PCM will see the 5 volts and know the circuit is bad.
The PCM will then set an open circuit fault.
STOP LAMP SWITCH
DESCRIPTION
The switch is mounted on the brake pedal mount-
ing bracket under the instrument panel.
OPERATION
Vehicles equipped with the speed control option use
a dual function stop lamp switch. The PCM monitors
the state of the dual function stop lamp switch. Refer
to the Brake section for more information on stop
lamp switch service and adjustment procedures.
The brake switch is equipped with three sets of
contacts, one normally open and the other two nor-
mally closed (brakes disengaged). The PCM sends a
12 volt signal to one of the normally closed contacts
in the brake switch, which is connected to a ground.
With the contacts closed, the 12 volt signal is pulled
to ground causing the signal to go low. The low volt-
age signal, monitored by the PCM, indicates that the
brakes are not applied. When the brakes are applied,
the contacts open, causing the PCM's output voltage
to go high, disengaging the speed control also
grounding the dump solenoid.
The second set of normally closed contacts is sup-
plied battery voltage any time speed control is
selected. From the brake switch, current is routed to
the speed control servo solenoids. The speed control
solenoids (vacuum, vent and dump) are provided this
current any time the speed control is ON and the
brakes are disengaged. When the driver applies the
brakes, the contacts open and current is interrupted
to the solenoids. The normally open contacts are fed
battery voltage. When the brakes are applied, battery
voltage is supplied to the stop lamps.
SERVO CABLE
DESCRIPTION
The speed control servo cable is connected between
the speed control vacuum servo diaphragm and the
throttle body control linkage.
OPERATION
This cable causes the throttle control linkage to
open or close the throttle valve in response to move-
ment of the vacuum servo diaphragm.
VACUUM RESERVOIR
OPERATION
The reservoir stores engine vacuum in the reser-
voir. When engine vacuum drops, as in climbing a
grade while driving, the reservoir supplies the vac-
uum needed to maintain proper speed control opera-
tion. The vacuum reservoir cannot be repaired and
must be replaced if faulty.
VEHICLE SPEED SENSOR
The Vehicle Speed Sensor (VSS) is a pulse genera-
tor mounted to an adapter near the transmission out-
put shaft. The sensor is driven through the adapter
by a speedometer pinion gear. The VSS pulse signal
to the speedometer/odometer is monitored by the
PCM speed control circuitry to determine vehicle
speed and to maintain speed control set speed.

DESCRIPTION AND OPERATION
WINDSHIELD WASHER NOZZLE(S)
This model is equipped with two hood mounted
washer nozzles. Each nozzle emits two streams into the
wiper pattern (Fig. 1). If the nozzle performance is
unsatisfactory they can be adjusted. To adjust insert a
pin into the nozzle ball and move to proper pattern (Fig.
2). The right and left nozzles are identical.
WINDSHIELD WASHER SYSTEM
All models are equipped with electrically operated
windshield washer pumps. The wash function can be
accessed in the OFF position of the wiper control
switch. Holding the wash button depressed when the
switch is in the OFF position will operate the wipers
and washer motor pump continuously until the
washer button is released. Releasing the button will
stop the washer pump but the wipers will complete
the current wipe cycle. Followed by an average of two
more wipe cycles (61) before the wipers park and the
module turns off.
The electric pump assembly is mounted directly to
the reservoir. A permanently lubricated motor is cou-
pled to a rotor type pump. Fluid, gravity fed from the
reservoir, is forced by the pump through rubber hoses
to the hood mounted nozzles which direct the fluid
streams to the windshield.
The pump and reservoir are serviced as separate
assemblies (Fig. 3).
