Door Key Lock and Unlock Switch Circuit (Unlock Side)
CIRCUIT DESCRIPTION
The Key±operated switch is built into the door key cylinder. When the key is turned to the lock side, the lock
terminal of the switch is grounded, and when the key is turned to the unlock side the unlock terminal is
grounded.
Furthermore, the door key lock and unlock switch circuit has terminal +B connected inside the theft deterrent
ECU, when neither the lock nor unlock terminal of the key lock and unlock switch are grounded, battery posi-
tive voltage is applied to the door key lock and unlock switch circuit of the wireless door lock ECU.
( Tr inside the ECU coming ON causes the wireless door lock ECU to output a signal to unlock all the doors.)

DTC 12 Actuator 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 speed sensor, etc. during cruise control opera-
tion, 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 km/h (9 mph), the ECU turns the
safety magnet clutch OFF. If the vehicle speed later drops to within 10 km/h (6 mph), cruise control at the
set speed is resumed.
