Cruise Control System

DTC 12 ACTUATOR MAGNETIC CLUTCH CIRCUIT

CIRCUIT DESCRIPTION

Detection Item:

This circuit turns on the magnetic clutch inside the actuator during the cruise control operation according to the signal from the ECU. If a malfunction occurs in the actuator or speed sensor, etc. during the cruise control operation, the rotor shaft between the motor and control plate is released.

When the brake pedal is depressed, the stop light switch is turned on and the power supply to the magnetic clutch is mechanically cut, and therefore the magnetic clutch is turned OFF.

When driving downhill, if the vehicle speed exceeds the set speed by 15 km/h (9 mph), the ECU turns the safety magnet clutch OFF. If the vehicle speed later drops by 10 km/h (6 mph) from that speed, cruise control at the set speed is resumed.
