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.

NOTE Defined
A NOTE statement immediately precedes or follows an operating procedure, maintenance practice or condition that
requires highlighting. A NOTE statement also emphasises necessary characteristics of a diagnostic or repair procedure.
A NOTE statement is designed to:
• Clarify a procedure,
• Present additional information for accomplishing a procedure,
• Give insight into the reasons for performing a procedure in the recommended manner, and / or
• Present information that gives the technician the benefit of past experience in accomplishing a procedure with
greater ease.
1.2 System Components
The main components of the electronic cruise control system are:
• cruise control ON / OFF switch (in dash panel).
• cruise control switch assembly (incorporated into wiper and washer switch assembly),
• instrument cluster assembly (cruise set lamp),
• clutch pedal switch assembly (manual transmission vehicles only),
• stop lamp switch assembly,
• powertrain interface module (PIM),
• engine control module (ECM),
• throttle actuator control (TAC) assembly, and
• electrical wiring (incorporated into the main wiring harness).
