CRUISE CONTROL SYSTEMA6E404018881205Outline
•The cruise control system has been adopted for MZR-CD (RF Turbo) engine models.
•Cruise control module has been equipped into the PCM. Due to this, the PCM controls cruise control system.
•Function of the cruise control system is basically the same as that of the Mazda6 (GG) L series engine model,
except for the following:
—The PCM controls the fuel injection amount to maintain vehicle speed.
.
Operation
Operating condition
•The PCM can excute cruise control when the following conditions are met:
—Cruise control main switch is on
—Brake pedal is released (brake switch 1 is off, brake switch 2 is on)
—Clutch pedal is released (clutch switch is off)
—Gear is not neutral position (neutral switch is off)
—Vehicle speed of 27 km/h {16.7 mph} or more
—No DTC is memorized
Driving at set speed
•Once the desired speed has been set, the PCM determines the target fuel injection amount based on the
vehicle speed signal.
•If the actual vehicle speed goes below the set speed, the PCM increases the fuel injection amount, and if it
goes above the set speed the PCM decreases the fuel injection amount.
Tap up/Tap down operation
•When driving at a set speed, if the SET/COAST or RESUME/ACCEL signal is input to the PCM for a very short
interval, the set speed will be increased or decreased respectively by 6 km/h {3.7 mph}.
