8B-2 CRUISE CONTROL SYSTEM
General Description
The cruise control keeps the vehicle running at a fixed speed until a signal canceling this fixed speed is received.
W hen the main switch “AUTO CRUISE” is turned on with the vehicle in the running mode, the battery voltage is
applied to the control unit (Engine control module). W hen a signal from the control unit while the vehicle is in this
state, the cruise control actuator is activated to operate the system. Also, while the system is operating, the cruise
control set indicator light in the meter assembly lights up.

1. SET/COAST Switch Function
1. Set Function: W hen the SET/COAST switch is pressed and released with the main switch on, the speed at
which the vehicle is running at that moment is stored in the memory, and the vehicle automatically runs at the
stored speed.
2. COAST-down Function: W hen the SET/COAST switch is kept on while the vehicle in running, the vehicle
decelerates during that time. The speed at which vehicle is running when the control switch is pressed in the
memory, and the vehicle automatically returns to the stored speed.
3. Tap-down Function: W hen the SET/COAST switch is pressed and released instantaneously while the
vehicle is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the
vehicle was running when the SET/COAST was released last is stored in the memory, and the vehicle
automatically returns to this stored speed.

2. RESUME/ACCEL Switch Function
1. Resume Function: W hen the RESUME/ACCEL switch is turned on/off after the system is temporarily
deactivated by pressing the brake or clutch pedal while the vehicle is running, the vehicle resumes the speed
stored before the system was released, and the vehicle automatically runs at the stored speed.
2. Accelerate Function: W hen the RESUME/ACCEL switch is kept on the vehicle accelerates its speed during
that time. The vehicle speed at which the vehicle was running when the switch was turned off is stored in the
memory, and the vehicle automatically returns to this speed.
3. Tap-up Function: W hen the RESUME/ACCEL switch is turned on and off instantaneously while the vehicle
is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the vehicle
was running when the switch was turned off last is stored in the memory, and the vehicle automatically
returns to this stored speed.

Cruise Control – HFV6 Page 8C–6
The stop lamp switch contacts are normally open with the brake pedal at rest and close when the brake pedal is pressed
turning on the vehicles brake lamps. These switch contacts also double as the cruise cancel signal for the cruise control
operation.
The cruise control initial brake apply signal function switch contacts are normally closed with the brake pedal at rest and
open when the brake pedal is pressed. This switch function is a safety requirement of the vehicle as it ensures that the
cruise control cannot be activated without the brake pedal first being pressed.
Powertrain Interface Module
The Powertrain Interface Module (PIM) is located on the driver’s side, kick trim panel. The purpose of the PIM is to act as
an interface between the drivetrain serial data bus (GMLAN protocol) and the body side data bus (UART Bus protocol).
All inputs from the cruise control switch assembly are directly wired to the PIM. The PIM then takes these inputs,
converts them to GMLAN protocol and sends the messages via the data bus to the engine control module (ECM). The
PIM also receives signals for the cruise control system from the ECM. When the ECM activates cruise control, it sends a
signal through the PIM (which converts it from GMLAN to UART protocol) to display the various cruise control messages
on the instrument cluster assembly.
For further information on the operation of the PIM, refer to 6E1 Powertrain Interface Module – V6.
Engine Control Module
The Engine Control Module (ECM) is mounted on the front of the engine. The role of the ECM is to receive all the inputs
from various sensors (vehicle speed (VSS) etc.) and switches to manage the engine. W hen a request is sent from the
cruise control switch assembly via the PIM to the ECM, the ECM will activate cruise control providing given parameters
are satisfied. Once the cruise is set, the ECM monitors the vehicle speed and controls the throttle actuator assembly thus
controlling the speed of the vehicle.
For further information on the operation of the ECM, refer to 6C1-1 Engine Management – V6 – General Information.
Throttle Actuator Control (TAC) Assembly
The throttle actuator control assembly is located on the front of the inlet manifold. The throttle actuator control assembly
receives signals from the ECM and controls the angle of the throttle plate. Refer to 6C1-1 Engine Management – V6 –
General Information for further information.
1.3 System Operation
Preliminary Information
Enabled and Disabled
The cruise control is enabled / disabled by pressing the cruise control ON–OFF switch mounted on the lower right hand
side of the dash panel. When cruise control is enabled, the cruise control ON–OFF switch illuminates and the cruise
control is ready for a speed to be set (cruise control activated). W hen the cruise control is disabled, the cruise control
cannot be activated.

Cruise Enabled
1 The cruise control ON–OFF switch (1) supplies 12 Volts to the Powertrain Interface Module (PIM) when it
is pressed.
2 The cruise control ON–OFF switch lamp (2) turns on.
Cruise Disabled
1 W hen cruise control ON–OFF switch (1) is pressed again, power is removed from the PIM disabling the
cruise control.
2 The cruise control ON–OFF switch lamp (2) turns off.
