							CRUISE CONTROL - V8i

DESCRIPTION AND OPERATION CRUISE CONTROL SYSTEM-HELLA GR66
Description
The cruise control system consists of
electro-mechanical devices, and comprises of the
following components.
ELECTRONIC CONTROL UNIT (ECU)
The engine control module is located behind the lower
dash panel. The microprocessor based ECU
evaluates the signals provided by the driver controls,
brake pedal switch, clutch pedal switch on manual
models, and the vehicle speed sensor. The ECU
activates the vacuum pump as required. The ECU
also has a memory function for set speed storage.
Driver operated switches
The main cruise control switch is located in the
auxiliary switch panel and activates the cruise control
system. The steering wheel switches provide
set/accelerate and resume/decelerate features.
These switches provide the interface between driver
and cruise control system.
Brake pedal switch
The brake pedal switch is located under the lower
dash attached to the brake pedal mounting bracket.
The switch provides for fast disengagement of the
cruise control system and rapid return of the throttle
levers to the idle position when the brake pedal is
applied.
Clutch pedal switch
The clutch pedal switch is located under the lower
dash attached to the clutch pedal mounting bracket.
The switch provides for fast disengagement of the
cruise control system and rapid return of the throttle
levers to the idle position when the clutch pedal is
applied.Vehicle speed sensor
The vehicle speed sensor is located on the side of the
transfer box adjacent to park brake. The sensor
provides road speed data to the ECU. The cruise
control system cannot be engaged until the road
speed exceeds 45 km/h, (28 mph) the system will
automatically disengage at a road speed of 42 km/h
(26 mph).
Vacuum pump
The vacuum pump is located in the engine
compartment, attached to the left hand valance. The
vacuum pump is energised when the main cruise
control switch is operated, and is actuated by the
steering wheel and brake pedal switches. The pump
provides a vacuum source to the cruise control
actuator at the throttle levers. A control valve in the
pump provides for steady increase of road speed or
purge of the system when the brake pedal is applied.
Actuator
The actuator is located in the engine compartment
and is bolted to the throttle lever bracketry. The
actuator provides the servo mechanism link between
the cruise control system and throttle linkage and is
operated by vacuum from the vacuum pump.
Neutral lockout relay module-cruise control -
Automatic vehicles
The relay module is located in the right hand side
footwell, accessible by removing the trim panel.
The function of the relay module is to disengage the
cruise control system if neutral, or park, is selected in
the main gearbox, when the system is engaged.
Engine speed trip ECU - Manual vehicles
This unit is located in the right hand side footwell,
accessible by removing the trim panel.
The function of the unit is to disengage cruise control
if engine speed exceeds 5000 rev/min.

FAULT DIAGNOSIS ROAD TEST
CAUTION: Do not engage cruise control
when vehicle is being used in low transfer
gear or reverse.
WARNING: The use of cruise control is not
recommended on winding, snow covered
or slippery roads or in heavy traffic
conditions where a constant speed cannot be
maintained.
1.Start engine, depress main control switch to
actuate cruise control system. Accelerate to
approximately 50 km/h, (30 mph), operate
set/accswitch, immediately release switch,
remove foot from accelerator pedal. Vehicle
should maintain speed at whichset/accswitch
was operated.
2.Operateset/accswitch and hold at that
position, vehicle should accelerate smoothly until
switch is released. Vehicle should now maintain
new speed at whichset/accswitch was
released.
3.Momentarily touch and releaseset/accswitch,
vehicle speed should increase 1.6 km/h (1 mph)
for each touch. Note that five touches will
increase speed 8 km/h (5 mph).
4.Applyres/decelswitch while vehicle is in cruise
control mode, cruise control should disengage.
Slow to approximately 55 km/h, (35 mph)
operateres/decelswitch, immediately release
switch and remove foot from accelerator, vehicle
should smoothly accelerate to previously set
speed. Increase speed using accelerator pedal,
release pedal, vehicle should return to previously
set speed.5.Operate brake pedal, cruise control system
should immediately disengage returning vehicle
to driver control at accelerator pedal. Operate
res/decelswitch, vehicle should accelerate to
previously set speed without driver operation of
accelerator pedal.
6.Operateres/decelswitch and allow vehicle to
decelerate to below 42 km/h, (26 mph). Operate
res/decelswitch, cruise control system should
remain disengaged.
7.Operateset/accswitch below 40 km/h, (28
mph), cruise control system should remain
disengaged. Accelerate, using accelerator pedal
to above 45 km/h, (28 mph), operateres/decel
switch, and remove foot from accelerator pedal,
vehicle should smoothly adjust to previously
memorised speed.
8. Automatic vehicles- select neutral, system
should disengage.Manual vehicles- depress
clutch, system should disengage.
9.Cruise at 80 km/h (50 mph), declutch, select
neutral, remove foot from clutch. Operate
res/decelswitch. Engine should rev to 5000
rev/min, cruise control disengages, engine
returns to idle.
10.Engage forward gear. Operateres/decel
switch. Remove foot from accelerator. Speed
should accelerate to previous set speed.
11.Depress main control switch in control system
should immediately disengage and erase
previously set speed from ECU memory.
