DTC 12 - ACTUATOR MAGNETIC CLUTCH CIRCUIT

DTC 12 Magnetic Clutch Circuit:

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 vehicle speed sensor, etc. during cruise control, the rotor shaft between the motor and control plate is released.


When the brake pedal is depressed, the stop light switch 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 15 kph (9 mph), the ECU turns the magnetic clutch OFF. If the vehicle speed later drops to within 10 kph (6 mph) above the set speed, then cruise control at the set speed is resumed.
