Ts Terminal Circuit
CIRCUIT DESCRIPTION
The sensor check circuit detects abnormalities in the speed sensor signal which cannot be detected with
the DTC check. Connecting terminals Ts and E1 of the DLC1 in the engine compartment starts the check.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
PREPARATION:
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Ts and E1 of the
DLC1.
OK:
Voltage: 10 − 14 V
OK If ABS warning light does not blink even after Ts
and E1 are connected, ECU may be defective.

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 vehicle speed sensor, etc. during cruise con-
trol, 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
magnetic clutch OFF. If the vehicle speed later drops to within 10 km/h (6 mph) above the set speed, then
cruise control at the set speed is resumed.

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
When the brake is on, battery positive voltage normally applies through the stop fuse and stop light switch
to terminal STP− of the ECU, and the ECU turns the cruise control off.
A fail−safe function is provided so that cancel functions normally, even if there is a malfunction in the stop
light signal circuit.
If the harness connected to terminal STP− has an open, terminal STP− will have battery positive voltage and
the cruise control will be turned off, also SET not occurring.
Also, when the brake is on, the magnetic clutch is cut electrically by the stop light switch, turning the cruise
control off. (See page DI−338 for operation of the magnetic clutch)

Idle Switch Circuit
CIRCUIT DESCRIPTION
When the idle switch is turned ON, a signal is sent to the ECU. The ECU uses this signal to correct the dis-
crepancy between the throttle valve position and the actuator position sensor value to enable accurate
cruise control at the set speed. If the idle switch is malfunctioning, problem symptoms also occur in the en-
gine, so also inspect the engine.
