1. GENERAL I NFORMATION
Cruise control is a vehicle speed control system which maintains a desired vehicle speed without the driver having
to continually apply foot pressure to the accelerator pedal.
Depending on the model var iant, cruis e control is available as either standar d or optional equipm ent on all MY 2003
VY and V2 Series models with either automatic or manual transmission.
The cruise control system is an Electro-motor system, i.e. it uses a stepper motor to control vehicle speed.
On m odels fitted with GEN III V8 engine and traction control, a throttle relaxer servo is f itted as part of the traction
control system to pr ovide engine torque c ontrol. The thr ottle relaxer m om entarily reduces the throttle opening angle
when traction loss occurs.
There is no electronic interface between the throttle relaxer and the cruise control module.
1.1 SYSTEM OPERATION
The main components of the Electro-motor cruise control system are:
• Module Assembly – Cruise Control (cruise control module);
• Switch Assembly – Cruise Control (cruise control switch assembly, incorporated into the turn signal switch
assembly);
• Brake pedal stop lamp switch (Switch A);
• Brake pedal electrical release switch (Switch B);
• Clutch pedal switch and patch harness (manual transmission models);
• Cruise control cable; and
• Electrical wiring (incorporated into the main wiring harness).
The cruise control module also uses an output from the Powertrain Control Module (PCM) for vehicle speed, and
provides an input to the instrument cluster for cruise control status indication.
When the c r uise contr ol module is powered up via the cr uis e c ontrol O N- OF F push- button s witch, the cr uis e contr ol
module activates an input to the instrument cluster. The instrument cluster sees this line as active and sends a
message to the Multi-function Display (MFD) to turn its CRUISE icon on.
W hen the CRUISE switch is rotated to the SET -DECEL position (provided the vehicle s peed is above 40 km/h and
either the brake or clutch pedal is not pressed) the cruise control module activates an input to the instrument
cluster. The instrument cluster sees this line as active and sends a mess age to the MFD to turn its ACTIVE icon on
and in tur n, the instrument c luster inform s the PCM via the serial data interf ace to use a specif ic transm ission shift
pattern. T he transm iss ion s hift pattern is des igned primar ily for cruise m ode, having f ewer trans m ission down shif ts
and reduc ed trans miss ion gear c hange ac tivity. For f urt her inf or mation about the PCM cr uis e contr ol inter f ace, r ef er
to Section 6C, POWERTRAIN MANAGEMENT.
Figure 12E-1 illustrates the component relationship for the cruise control sy stem.

COMPONENTS
The cruise control module (1) is mounted forward
of the right-hand s trut tower (2) and adjacent to the
optional ABS/TCS module (3), on both LHD and
RHD vehicles, regardless of the engine variant.
Refer to Figure 12E-2, RHD shown.
Figure 12E-2
The c ruis e c ontrol module f unctionally integrates an
electronic controller (1) with an electric stepper
motor (2).
The electronic controller monitors vehicle speed
from a signal generated by the PCM which in turn,
operates the electric stepper motor.
The stepper motor, in response to the electronic
controller, adjusts the throttle position to maintain
the desired vehicle set speed. The electronic
controller is operated by the cruise control system
control switches (3), RHD model shown, located at
the tip of the headlamp and turn signal switch
assembly.
Figure 12E-3
Two switches, mounted on the brake pedal
support (1), disengage the cruise control system
electronically when the brake pedal (2) is pressed.
The upper switch (3) is the cruise control electrical
release switch (Switch B). The two rear terminals
are used for the cruise control system.
NOTE: Us ing the front set of terminals will res ult in
the cruise control not functioning.
The lower switch (4) is the brake pedal stop lamp
switch (Switch A), and is used to illum inate the stop
lamps and signal the cruise control module to
disengage.
With the brake pedal at rest, the stop lamp contacts
in the lower switch are open, and closed when the
brake pedal is pressed.
With the brake pedal at rest, the electrical release
contacts in the upper switch are closed, and open
when the brake pedal is pressed.
Both switches are used to signal the cruise control
module s o that if one should f ail, the second switch
will still generate a signal to the cruise control
module to disengage the cruise control function.
Figure 12E-4
For vehicles with a manual transmission, a clutch
pedal switch (1) mounted on the clutch pedal
support (2), has been incorporated into the cruise
control system. W hen the driver presses the clutch
pedal (3) to change gear, the cruise control is
disengaged.
When the clutch pedal is pressed, a signal is
transmitted to the cruise control module to
disengage the cruise control function.
With the clutch pedal at rest, the contacts of the
clutch switch are c losed, and open when the clutch
pedal is pressed.
Figure 12E-5
The cruise control module comprises of an
electronic controller (1) and electric stepper motor,
solenoid operated clutch and gear train
assemblies (2), and a connecting strap (3).
The electronic controller receives signals from the
cruise control electrical release switch, stop lamp
switch, clutch pedal switch and vehicle speed
output. It then generates signals to control the
stepper m otor and solenoid operated cr uise control
module clutch.
The electric stepper motor is a brushless type
motor with a four pole perm anent magnet arm ature
and three phase stator. The motor provides torque
through a mechanical gear train to a control cable,
which actuates the throttle linkage.
When the brake pedal electrical release switch is
activated (brake pedal pressed) the stepper motor
begins to spin the motor back to the zero motor
position. If the signal at pin X1-G (refer to
Figure 12E-43) of the cruise control module is
pulled high, it will cause the stepper m otor clutch to
de-energise in about 0.75 second. In most cases,
the stepper motor will be in the zero position when
the module clutch is disengaged. This time delay
period is introduced to prevent the accelerator
pedal from slapping while the throttle is still held
open. The stepper motor relies on the throttle
return s pr ing to r eturn the s tepper motor to the zero
position as the spring on the drum gear is not
strong enough to return the throttle/cruise to zero.
The internal components of the cruise control
module are not serviceable.
CAUTION: Do not attempt to repair the cruise
control module assembly if faulty.
Unauthorised repair of the cruise control
module will affect vehicle safety.
Figure 12E-6
CRUISE CONTROL SWITCH OPERATION
Engaging the Cruise Control
With the ignition switched on, press the CRUISE
ON-OFF push-button (1), RHD model shown. This
will cause the ‘Cruise Enabled’ message to be
displayed for 2 seconds on the instrument cluster
MFD along with the cruise symbol with a flashing
set arrow and the CRUISE icon, refer to
Figure 12E-8. The instrument cluster MFD then
reverts to just the CRUISE icon, indicating that
power is on.
Accelerate the vehicle to the desired cruise speed
(above 40 km/h) and rotate the CRUISE switch (2)
to the SET-DECEL position (3) and release, then
release the accelerator pedal.
Figure 12E-7
The ‘Cruise Enabled’ message (1), the cruise
symbol with a flashing set arrow (2) and the
CRUISE icon (3) will be displayed on the
instrument cluster MFD for 2 seconds when the
cruise control system is turned on at the control
switch located on the turn signal switch assembly.
The instrum ent cluster MFD then reverts to j ust the
CRUISE icon (3) indicating that power is on.
The ACTIVE icon (4) in the instrum ent cluster MFD
will be displayed when the cruise control system is
engaged. The cruise speed will be automatically
maintained, provided the vehicle speed is above
40 km/h.
Figure 12E-8
To Change Cruise Speed
To reset the cruise control to a higher speed,
accelerate the vehicle to the desired speed, rotate
the CRUISE switch (1) to the SET-DECEL
position (3) and release it. Refer to Figure 12E-9,
RHD model shown.
Rotating the CRUISE switch (1) to the RES-ACCEL
position (2) will cause an increase in cruise speed
and the vehicle will accelerate at a controlled rate
until the CRUISE switch is released. The vehicle
will now cruise at this higher set speed.
To decrease the cruise speed, rotate the CRUISE
switch to the SET-DECEL position (3). The vehicle
will decelerate, coasting to a slower speed at a
controlled rate until the CRUISE switch is released.
The vehicle will now continue to cruise at the
reduced set speed.
NOTE: While holding the CRUISE switch in the
SET-DECEL position, the ACTIVE icon (4) in the
instrument cluster MFD (refer to Figure 12E-8) will
turn OFF . The ACTIVE ic on will be displayed again
when the CRUISE switch is released.
The cruise control switches also provide the facility
for TAP UP and TAP DOWN for smaller
incremental adjustments in vehicle cruise speed.
TAP UP is ac hieved by quickly rotating the CRUISE
switch to the RES-ACCEL position and releasing.
The cruise speed will increase by 2.0 km/h for
every TAP UP. Quickly rotating the CRUISE switch
to the SET-DECEL position (TAP DOWN) will
decrease the cruise control speed by 2.0 km/h for
every TAP DOW N. T AP DOW NS are lim ited to the
minimum cruising speed of 40 km/h.
Figure 12E-9
To Override the Cruise Control System
The acceler ator pedal m ay be pressed at any time to overr ide the cruis e control s ys tem . Release of the acceler ator
pedal will return the vehicle to the cruise speed set previously.
To Disengage the Cruise Control System
The system is disengaged when:
1. The brake pedal is pressed.
2. The clutch pedal is pressed (for vehicles with manual transmission).
3. The ON-OFF push-button is pressed switching the cruise control system to the Standby mode.
IMPORTANT: When vehicles fitted with Electronic T raction Control are in a low traction situation, the c ruise control
will disengage.
When the cruise control system is disengaged, the ACTIVE icon goes out but the CRUISE icon remains.
To resume the previously set cruise control memory speed after changing gear, braking, stopping or pressing the
ON-OFF switch once; first accelerate, if required, until the vehicle speed is greater than 40 km/h, then rotate the
CRUISE switch to the RES-ACCEL position ( for less than 1 s econd). The vehicle will then autom atically acceler ate
to the previous cruise speed setting.
The cruise control module will retain the previous set speed in memory for as long as the CRUISE icon is on.
Pressing the clutch pedal or brake pedal, or pressing the ON-OFF switch once while the ACTIVE icon is, will not
erase the vehicle set speed from the cruise control module memory.
Pressing the ON-OFF switch while only the CRUISE icon is on or turning the ignition off, will erase the previous
cruise set speed from the cruise control module memory.
NOTE: Each tim e the ignition is cycled, the CRUISE and ACTIVE icons will go out. To reactivate the cruise control,
the CRUISE ON-OFF switch will have to be pressed.

3. DIAGNOSIS
3.1 PRELIMINARY DIAGNOSIS AND INSPECTION
NOTE: If a vehic le is fitted with traction contr ol, the cruise control system will disengage or fail to engage whenever
the LOW TRAC icon is displayed on the instrum ent cluster MFD, and will not engage or re-engage until the LOW
TRAC icon turns off.
When a vehicle is sus pected of having a cruis e control s ystem operation malf unction, it is im portant to carr y out the
following preliminary diagnosis. This diagnosis should be used to determine whether the cruise control system
problem is the result of an actual system defect, or the result of a problem with some other vehicle component.
Also, s om e c ruise control system c om plaints m ay be a misunders tanding by the driver about how the cruise contr ol
system f unctions . In that c as e, the operation of the s ystem should be ex plained in a manner the dr iver unders tands .
A practical demonstration is very useful to explain system operation.
If it is decided the cruise control system is at fault, perform a visual inspection of all components in the system.
Cruise control system malfunctions can be caused by mechanical, electrical, or a combination of both problems.
Things to check are:
1. Switch inputs to the cruise control module.
2. Dirty, corroded, or loose electrical connections.
3. Damaged or incor rectly adjusted stop lam p switch (Switch A). Refer to 2.4 ST OP LAMP SWITCH (SW IT CH A)
in this Section for test and adjustment procedure.
4. Damaged or incorrectly adjusted electrical release switch (Switch B). Refer to 2.5 ELECTRICAL RELEASE
SWITCH (SWITCH B) in this Section for test and adjustment procedure.
5. Damaged or inoper ative clutch pedal s witch. Refer to 2.6 CLUT CH PEDAL SWITCH in this Sec tion f or tes t and
adjustment procedure.
6. Binding or sticking throttle linkage.
7. Broken components (eg. cruise control cable).
8. Bare, broken or disconnected wires.
9. Adjustment of the control cable, refer to 2.1 CRUISE CONTROL CABLE in this Section.
10. On vehicles fitted with GEN III V8 engine and traction control, ensure that the throttle relaxer is functioning
correctly. Refer to Section 12L, ABS AND ABS/ETC.
11. If pr elim inary inspection reveals no problem , and the s ystem is m alfunc tioning, refe r to 3.3 SELF DIAGNOSTIC
TEST in this Section.
NOTE: Verify that the problem exists before attempting any repairs. Sometimes normal operating characteristics
may be misunderstood as a problem.
3.2 CRUISE CONTROL SYSTEM FUNCTIONAL CHECK
The f ollowing procedure s hould be used to chec k the oper ating m odes of the cruis e control s ystem. T his procedure
should always be used after repair work has been completed on the cruise control system.
ROAD TEST PROCEDURE
1. Check ON-OFF activation: Ignition on, press the cruise control ON-OFF push-button to turn the system on;
system CRUISE icon should illuminate.
2. Check the low speed inhibit: Drive the vehicle at 30 km/h. Rotate the CRUISE switch to the SET-DECEL
position and release. Cruise control must not engage and only the CRUISE icon should be illuminated.
3. Check set speed: Drive the vehicle at a steady speed of 60 km/h. Rotate the CRUISE switch to the
SET-DECEL position and release. The cruise control should engage at approximately 60 km/h and both the
CRUISE and ACTIVE icons must illuminate.
4. Check b rake release: With the cruis e c ontrol system engaged, pr ess the br ak e pedal. The c ruise c ontrol m ust
release the throttle, allowing vehicle speed to drop. The system must not re-engage when the brake pedal is
released. The ACTIVE icon must go out but the CRUISE icon should remain on.
5. Check clu tch release (manual t ransmission only): With the cruis e control system engaged, pr ess the clutch
pedal. The c ruise control m ust r elease the throttle, allowing the vehicle speed to drop. The system m ust not re-
engage when the clutch pedal is released. The ACTIVE icon must go out but the CRUISE icon should remain
on.
6. Check resume feature: With the vehicle speed at approximately 50 km/h, rotate the CRUISE switch to the
RES-ACCEL position and release. The vehicle should accelerate to approximately 60 km/h and the CRUISE
and ACTIVE icons should illuminate again.
7. Check coast feature: Rotate the CRUISE switch to the SET-DECEL position and hold. Only the ACTIVE icon
must go out. Allow the vehicle speed to drop to 50 km/h and release the CRUISE switch. The cruise control
should hold the vehicle speed at approximately 50 km/h and both the ACTIVE and CRUISE icons should be
illuminated.
8. Check accelerator feature: Rotate the CRUISE switch to the RES-ACCEL position and hold. The vehicle
speed should begin to increase. Allow the speed to increase to 60 km/h and release the switch. The cruise
control s hould hold the vehicle s peed at approximately 60 km /h. Both the ACT IVE and CRUISE ic ons should be
illuminated.
9. Check coast down mode:
a) Press and release the ON-OFF push-button. The vehicle should begin to slow down (this has the same effect
as holding the CRUISE switch in the SET-DECEL position). In this m ode, the cruise is deactivated and allows
the vehicle to slow down but the CRUISE icon remains illuminated. Allow the vehicle to slow to approximately
50 km/h then rotate the CRUISE switch to the RES-ACCEL position and release. The vehicle must return to
approximately 60 km/h and both the CRUISE and ACTIVE icons should be illuminated.
b) Press and release the ON-OFF push-button and allow vehicle to slow to approximately 50 km/h again then
rotate the CRUISE switch to the SET-DECEL position. The vehicle speed must hold at 50 km/h and both the
CRUISE and ACTIVE icons should be illuminated.
c) Press the ON-OFF pus h-button again and allow the vehicle to coast down. Only the CRUISE icon should be
illuminated.
d) Press the ON-OFF push-button again while in coast down mode (Step c) to fully turn the cruise control
system off. Both the CRUISE and ACTIVE icons must go out.
3.3 SELF DIAGNOSTIC TEST
To provide a means of checking the brake switch, clutch switch, cruise release switch, speed sensor inputs and
electro-motor operation, the cruise control system incorporates a self diagnostic facility.
Following the SELF DIAGNOSTIC TEST CHART is a detailed Diagnostic Chart to pin point the cause of a cruise
control system malfunction. Refer to 3.5 CRUISE CONTROL SYSTEM DIAGNOSTIC CHART in this Section.
Carry out the Self Diagnostic Test as outlined.
Jack up the vehicle and support on saf ety stands. Ref er to Section 0A GENERAL INFORMAT ION f or the location
of jacking points. Ensure that the drive shafts are horizontal.
