9. Auto Cancel Function
A) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, current flow to
the magnetic clutch is stopped and the cruise control is released, (CRUISE SW turns off).
When this occurs, the ignition SW must be turned off once before the CRUISE SW will turn on.
∗
When current continues to flow to the motor inside the actuator in the throttle valve ”OPEN” direction.
∗
The motor does not operate despite the motor drive signal being output.
B) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, current flow to
the magnetic clutch is stopped and the cruise control is released. (CRUISE SW turn off).
When this occurs, the cancel state is cleared as the CRUISE SW will turn on again.
∗
Over current to transistor driving the motor or the magnetic clutch.
∗
Open circuit in the magnetic clutch.
∗
Momentary interruption of vehicle speed signal.
∗
Short circuit in the cruise control SW.
C) If any of the following conditions occurs during cruise control operation, the set speed is erased and the cruise control is
released. (The power to the magnetic clutch is cut off until the SET SW is ”ON” again.)
∗
When the vehicle speed falls below the minimum speed limit, approx. 40 km/h (25 mph)
∗
When power to the cruise control system is momentarily cut off.
10. Automatic Transaxle Control Function (A/T)
∗
In overdrive. If the vehicle speed becomes lower than the overdrive cut speed (Set speed minus approx. 4 km/h, 2.5 mph)
during cruise control operation, such as driving up a hill, the overdrive is released and the power is increased to prevent a
reduction in vehicle speed.
∗
After releasing the overdrive, if the vehicle speed becomes higher than the overdrive return speed (Set speed minus
approx. 2 km/h, 1.2 mph) and the ECU judges by the signals from the actuator’s potentiometer that the upward slope has
finished, the overdrive is resumed after approximately 2 seconds.
∗
During cruise control driving, the cruise control operation signal is output from the cruise control ECU to the engine control
module. Upon receiving this signal, the engine control module changes the shift pattern to normal.
To maintain smooth cruise control operation (on a downward slope etc.), the lock–up release of the transaxle when the
idling point of the throttle position is ”ON” is forbidden.
