CRUISE CONTROL
SYSTEM OUTLINE
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
With the ignition SW turned to on, current flows through the GAUGE fuse to TERMINAL (C) 7 of the combination meter and
the current through the ECU–IG fuse flows to TERMINAL 9 of the cruise control ECU.
When the ignition SW is on and the cruise control SW is turned on, a signal is input from TERMINAL 5 of the cruise control
SW to TERMINAL 11 of the cruise control ECU. As a result, the cruise control ECU functions and the current flows from the
ECU–IG fuse to TERMINAL 9 of the cruise control ECU to TERMINAL 16 to GROUND, and the cruise control system is in a
condition ready for operation.
At the same time, the current through the GAUGE fuse flows to TERMINAL (C) 7 of the cruise control indicator light to
TERMINAL (C) 10 to TERMINAL 4 of the cruise control ECU to TERMINAL 16 to GROUND, causing the cruise control
indicator light to light up, indicating that cruise control is ready for operation.
1. SET OPERATION
When the cruise control SW is turned on and the set SW is pushed with the vehicle speed within the set limit (Approx. 40
km/h, 25 mph to 200 km/h, 124 mph), a signal is input to TERMINAL 10 of the cruise control ECU and the vehicle speed at
the time the set SW is released is memorized in the ECU as the set speed.
2. SET SPEED CONTROL
During cruise control driving, the cruise control ECU compares the set speed memorized in the cruise control ECU with the
actual vehicle speed input into TERMINAL 12 of the cruise control ECU from the speed sensor, and controls the cruise
control actuator to maintain the set speed.
When the actual speed is lower than the set speed, the ECU causes the current to the cruise control actuator to flow from
TERMINAL 15 of the cruise control ECU to TERMINAL 1 of the cruise control actuator to TERMINAL 2 to TERMINAL 7 of
the cruise control ECU. As a result, the motor in the cruise control actuator is rotated to open the than the set speed, the
current to the cruise control actuator flows from TERMINAL 7 of the cruise control ECU to TERMINAL 2 of the cruise control
actuator to TERMINAL 1 to TERMINAL 15 of the cruise control ECU.
This causes the motor in the cruise control actuator to rotate to close the throttle valve and return the throttle cable to
decrease the vehicle speed.
3. COAST CONTROL
During cruise control driving, while the coast SW is on, the cruise control actuator returns the throttle cable to close the
throttle valve and decrease the driving speed. The vehicle speed when the coast SW is turned off is memorized and the
vehicle continues at the new set speed.
4. ACCEL CONTROL
During cruise control driving, while the accel SW is turned on, the cruise control actuator pulls the throttle cable to open the
throttle valve and increase the driving speed.
The vehicle speed when the accel SW is turned off is memorized and the vehicle continues at the new set speed.
5. RESUME CONTROL
Unless the vehicle speed falls below the minimum speed limit (Approx. 40km/h, 25mph) after canceling the set speed by the
cancel SW, pushing the resume SW will cause the vehicle to resume the speed set before cancellation.
6. MANUAL CANCEL MECHANISM
If any of the following operations occurs during cruise control operation, the magnetic clutch of the actuator turns off and the
motor rotates to close the throttle valve and the cruise control is released.
∗ Placing the shift lever except D position (Park/Neutral position SW except D position). "Signal is not input to TERMINAL 3
of the cruise control ECU" (A/T)
∗ Depressing the clutch pedal (Cruise control clutch SW off). "Signal input to TERMINAL 3 of the cruise control ECU" (M/T)
∗ Depressing the brake pedal (Stop light SW on). "Signal input to TERMINAL 2 of the cruise control ECU"
∗ Pushing the cancel switch (Cancel SW on). "Signal input to TERMINAL 10 of the cruise control ECU"
∗ Pushing the cruise switch off "signal input to TERMINAL 11 of the cruise control ECU".
