- How the Circuit Works
With the ignition switch in ON (ll) or START (lll),
battery voltage is supplied through fuse 15 and the
BLK//EL wire to the vehicle speed sensor (VSS).
The sensor is grounded by the BLK wire to G101.
The speedometer and other control units in the
circuit supply about 5 volts to the ORN wire. The
vehicle speed sensor (VSS) intermittently grounds
the ORN wire which generates a pulsed signal in it.
The number of pulses per minute increases/
decreases with the speed of the car
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

Cruise Control (cont'd)
- How the Circuit Works
The cruise control system uses mechanical and
electrical devices to maintain the car's soeed at a
setting selected by the driver.
System Description
The cruise control unit receives command signals
from the cruise control main switch and the cruise
control SevBesume switch. With the ignition switch
in ON (ll) or START (lll), voltage is provided to the
cruise control main switch. When you push the
switch to on, power is provided to the cruise control
unit and the brake switch.
The cruise control unit receives information about
operating conditions from the brake switch, the
ignition control module (lCM), the vehicle speed
sensor (VSS), and the clutch switch (manual
transmission) or the A,/T gear positton switch
(automatic transmission). The cruise control unit
then sends signals to the cruise conirol actuator
which regulates the throttle position to maintain the
selected speed. The control unit compares the
aclual speed of the car to the selected speed. The
control unit then uses the result of that comoarison
to oDen or close the throttle.
The brake switch releases the system's control of
the throttle at the instant you press on the brakepedal. The switch sends a signal to the control unit
by removing power from the normally closed brake
input (GRY wire), and providing power at the
normally open brake input (GRNMHT wire). The
control unit responds by allowing the throttle to
close. The clutch switch or the A/T gear position
switch sends a "disengage" signal to the control unit
that also allows the throttle to close.
The cruise control system will set and automatically
maintain any speed above 25 mph (40 km/h). To set
it, make sure the main switch is on and the switch
indicator is on. Then, after reaching the desired
speed, press the set switch. This sends a "set"
signal to the cruise control unit which, in turn,
controls the cruise control actuator to maintain the
set soeed.
When you push the SET switch and the cruise
control system is on, the "cruise control" ON
indicator lights up.
34-4
You can cancel the cruise control system by
turning the main switch off. This removes power to
the control unit and erases the set sDeed from
memory. lf the system is disengaged temporarily
by the brake switch, or clutch switch, and the car's
speed is still above 25 mph, press the RESUME
switch: the car will automatically return to the
previously set speed.
For gradual acceleration without pressing the
accelerator pedal, push the RESUME switch and
hold it there. This will send an "acceleration" signal
to the control unit. When you release the switch, the
system will be reprogrammed tor the new speed. To
slow the car down, push the SET switch in and hold
it there. This sends a "deceleration" signal to the
control unit, causing the car to coast. When the
desired speed is reached, release the SET switch.
This reprograms the system for the new speed.
Reter to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
