•  The cruise control system is controlled by the PCM.
•  The PCM controls the fuel injection amount based on the input signals to maintain vehicle speed.

Component and function

Component

Function
DSC/ABS (CAN communication: Vehicle speed signal)
The vehicle speed signal is sent to the PCM from either the DSC.
Cruise control switch
ON
ON
The cruise control system main switch. The cruise control system goes into stand-by with the operation of the switch.
OFF
OFF
The cruise control system main switch. The cruise control system is turned off with the operation of the switch.
SET+/ SET-
SET+
If the switch is pressed upward when the vehicle speed exceeds 25 km/h {17 mph} with the system in stand-by, the vehicle speed at the point when the switch is pressed upward is stored in the PCM and the system initiates the cruise control.
The PCM controls acceleration by the pressing of the switch upward (tap-up operation) or when the switch is continuously pressed upward during cruise control.
SET-
If the switch is pressed downward when the vehicle speed exceeds 25 km/h {17 mph} with the system in stand-by, the vehicle speed at the point when the switch is pressed downward is stored in the PCM and the system initiates the cruise control.
The PCM controls deceleration by the pressing of the switch downward (tap-down operation) or when the switch is continuously pressed downward during cruise control.
RESUME
RESUME
If the switch is pressed when the vehicle speed exceeds 25 km/h {17 mph} with the system in stand-by and the previous pre-set vehicle speed stored in the PCM, the system initiates the cruise control so that the vehicle speed is the pre-set vehicle speed stored in the PCM.
CANCEL
CANCEL
If the CANCEL switch is pressed during cruise control, the cruise control system goes into stand-by (Pre-set vehicle speed is stored).
Brake switch
Depressing the brake pedal during cruise control switches the cruise control system to standby status.
CPP switch
Depressing the clutch pedal during cruise control switches the cruise control system to standby status.
Neutral switch
Shifting to neutral during cruise control switches the cruise control system to standby status.
PCM
The cruise control system is executed or stopped according to the cruise control switch signals. The fuel injector is operated so that the vehicle speed is the pre-set vehicle speed during cruise control system.
Fuel injector
The input signal sent from the PCM adjusts the fuel injection amount.
