Door Unlock Detection Switch Circuit
CIRCUIT DESCRIPTION
The door unlock detection switch is built in the door lock motor assembly. This switch is ON when the door
lock knob is in the unlock position and OFF when the lock knob is in the lock position. The ECU detects the
door lock knob conditions in this circuit. It is used as one of the operating conditions for the key confinement
prevention function.

DTC 11, 15 Actuator Motor Circuit
CIRCUIT DESCRIPTION
The actuator motor is operated by signals from the ECU. Acceleration and deceleration signals are trans-
mitted according to changes in the Duty Ratio (See below).
Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity
in one cycle, and B is the period of non±continuity.

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.

INSPECTION PROCEDURE
1 Check cruise control actuator arm locking operation
PREPARATION:
(a) Turn ignition switch OFF.
(b) Disconnect the actuator connector.
CHECK:
Connect the positive (+) lead from the battery to the terminal 3
of actuator and the negative (±) lead to terminal 4.
NOTICE:
Do not connect the high tension cables to the wrong bat-
tery terminal. The cruise control actuator will be damaged.
Move the control plate by hand.
OK:
Control plate doesn't move.
NG Replace cruise control actuator.

DTC 21 Open in Vehicle Speed Sensor Circuit
CIRCUIT DESCRIPTION
The signal from the vehicle speed sensor circuit is sent to cruise control ECU as vehicle speed signal.
The rotor shaft is driven by the gear of the transmission.
For each rotation of the shaft, the vehicle speed sensor sends a 4±pulse signal through the combination
meter to the cruise control ECU (See the following installation).
This signal is converted inside the combination meter and sent as a 4±pulse signal to the cruise control ECU.
The ECU calculates the vehicle speed from this pulse frequency.
DTC No.Detection ItemTrouble Area
21Speed signal is not input to the cruise control ECU while cruise
control is set.
