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.




RTU7Z0SH019601

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 Switch Assembly
The cruise control switch assembly is located on the end of
the wiper and washer switch assembly.
• For harness routing from the cruise control switch
assembly to the powertrain interface module, refer to
8A Electrical – Body and Chassis.
• For wiring and to see how the switch integrates into
the system, refer to 2.3 W iring Diagrams.
Figure 8C – 2
Instrument Cluster Assembly
The instrument cluster assembly displays the status of the cruise control system as well as other information via the
warning indicators.

Figure 8C – 3
Clutch Pedal Switch (Manual Only)
This switch assembly is attached to the clutch pedal support bracket. The switch is normally closed when the clutch
pedal is at rest, opening when the pedal is pressed. Activation of this switch removes the signal to the ECM, which will
then deactivate the cruise control.
Stop Lamp Switch Assembly
The stop lamp switch assembly is located on the brake pedal support bracket. This switch has two sets of contacts with
two independent functions. The function of the switch assembly in the cruise control system is to deactivate the cruise
control when the brake pedal is pressed as well as an initial safety check of the switch operation prior to activating cruise
control.

Cruise Control – HFV6 Page 8C–7
Activated and Deactivated
When the cruise control is enabled, the vehicle speed must be above 40 km/h and the cruise control switch assembly
pressed to SET–COAST, the cruise control will be activated and the vehicle will maintain the set speed. When
deactivated by the methods described within this section, the vehicle will no longer maintain the set speed, but the cruise
control will still be engaged.
Cruise Active
When the cruise control is activated via the cruise control
switch assembly, the cruise set warning lamp will illuminate
the instrument cluster assembly.
Cruise Deactivated
Upon receiving a signal to deactivate the cruise control the
ECM will provide a signal to the instrument cluster, via the
PIM, to inform the user the cruise control is deactivated.
When the cruise control is deactivated via the cruise control
switch assembly, the brake pedal, or the clutch pedal, the
cruise set warning lamp will turn OFF within the instrument
cluster assembly.
Figure 8C – 5
Enabling the Cruise Control
Refer to 2.3 Wiring Diagrams for the following description.
W hen the cruise control ON-OFF button is pressed, 12 V is applied to the powertrain interface module (PIM) connector
B – 97 pin 14. This informs the PIM the user has requested the cruise control function be engaged or disengaged. This
signal is then output by the PIM as GM LAN protocol along the bus to the engine control module (ECM). The ECM
recognises the command from the PIM to engage the cruise control. The PIM then provides a ground signal to B – 97 pin
13 the cruise control ON-OFF switch indicator lamp, to inform the user the cruise control is engaged.
Brake Before Cruise
Before the cruise control can be activated the driver must have applied the brakes and the system received a valid
response at least once per ignition cycle. If the driver manages to drive the vehicle without having used the brakes before
pressing the cruise control ON–OFF button, the cruise control cannot be activated.
Activating the Cruise Control
The user activates the cruise control at a desired speed above 40 km/h by pressing the cruise control switch assembly
SET–COAST button. This provides a 12 V signal to the PIM through connector B – 97 pin 15. The PIM then outputs this
signal as GM LAN protocol through the data bus to the ECM. If the ECM already has cruise control engaged, upon
receipt of the message from the PIM, the ECM will activate cruise control and set the speed. The ECM receives all the
various inputs required to maintain the correct speed and then controls the throttle actuator control assembly depending
on the load on the engine (ascending or descending hills, etc).
Deactivating the Cruise Control
When the cruise control is activated, it can be deactivated by any of the following:
Pressing the Brake Pedal
When the brake pedal is pressed, two signals are sent directly to the ECM by the circuits from the brake pedal switch
assembly. The cruise cancel circuit will open (normally closed) thus dropping the supply voltage from the ECM connector
C – 56 pin 46. Simultaneously, the stop lamp circuit will close (normally open) and supply 12 V to the ECM at connector
C – 56 pin 10. This is a double redundancy system so that if either switch or circuit from the brake pedal switch assembly
fails, the cruise control will still be deactivated.

11A-46 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
The ICU is installed to the steering lock. The ICU
controls the immobilizer system by authentication of the
transponder key and the ECM. An antenna coil is a part
of the ICU and it is located around steering key lock
cylinder. An antenna coil is energized when the ICU is
performing an authentication of the transponder key.
Engine Control Module (ECM)
Legend 1. ECM (4JK1/ 4JJ1)
2. ECM (HFV6)

The ECM is located inside of engine compartment via
mounting bracket and is behind air cleaner case (4JK1/
4JJ1) or attached to the engine (HFV6). The ECM
mainly controls the engine control and also exchanges
a request signal and a response signal to an ICU. If
fault occurs on immobilizer system, the ECM sets
DTC(s) and illuminates the service vehicle soon (SVS)
lamp or the malfunction indicator lamp (MIL). Powertrain Interface Module (PIM)
The PIM is located behind the driver’s side lower hinge
pillar trim. The PIM acts as the communication gateway
between the CAN communication protocol and other
protocol. The PIM converts analog signals from some
switches into serial data. The PIM upon inputs received
from the ECM, TCM and ICU controls the operation of
instruments and indicator lamps. (HFV6)
Transponder Key
Legend 1. Transponder chip

The transponder key accommodates a transponder
chip in the grip portion. The transponder keys have no
conventional power supply. The transponder chip is
energized via a radio wave supplied from an antenna
coil fitted around the steering lock cylinder. Only
transponder key that is correctly programmed key is
possible to engine run. Maximum five transponder keys
can be provided by additional programming.
