CRUISE CONTROL SYSTEM OUTLINE [MZI-3.7]

id0120c2100100

•  The cruise control system enables driving at a constant speed by setting the vehicle speed with the cruise control switch instead of operating the accelerator pedal.
•  The PCM controls the throttle valve actuator to maintain the vehicle at a constant speed.

Component and function

Component

Function

Installation location
RSC(CAN communication: Vehicle speed signal)
The vehicle speed signal is sent to the PCM from either the RSC.
Engine compartment
Cruise control switch
ON/ OFF
ON
The cruise control system main switch. The cruise control system goes into stand-by with the operation of the switch.
Steering wheel
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 24km/h {15 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 24km/h {15 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 24km/h {15 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.
Brake pedal
TCM/CAN communication: gear signal)
If the following operation is performed during cruise control, the cruise control system goes into stand-by (Pre-set vehicle speed is stored).
•  The selector lever is shifted from the D range to the N position.
Engine compartment
Parking brake switch
If the parking brake is operated during cruise control, the cruise control system goes into stand-by (Pre-set vehicle speed is stored).
Parking brake pedal
PCM
The cruise control system is executed or stopped according to the cruise control switch signals. The throttle valve actuator is operated so that the vehicle speed is the pre-set vehicle speed during cruise control system.
Engine compartment
Throttle valve actuator
The duty signal sent from the PCM adjusts the throttle valve opening angle.
Throttle body
Cruise main indicator light (Amber)
This illuminates light while the cruise control system is in control status.
Instrument cluster
Cruise set indicator light (Green)
This illuminates light while the cruise control system is in control status.
