Toyota Corolla (E120): Circuit description
This circuit turns on the magnetic clutch inside the actuator during cruise control operation according to the signal from the ecu. If a malfunction occurs in the actuator or speed sensor, etc. During cruise control operation, the rotor shaft between the motor and control plate is released.
When the brake pedal is depressed, the stop lamp switch assy turns on, supplying electrical power to the stop light. Power supply to the magnetic clutch is mechanically cut and the magnetic clutch is turned off.
When driving downhill, if the vehicle speed exceeds the set speed by 8 km/h (5 mph), the ecu turns the safety magnet clutch off. If the vehicle speed later drops to within 5 km/h (3 mph) above the set speed, then cruise control at the set speed is resumed.
