CIRCUIT DESCRIPTION
Connecting terminals Tc and E1 of the DLC1 causes the ECU to display the DTC by flashing the ABS warning
light.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Tc and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Tc and E1 of the
DLC1.
OK:
Voltage: 10 − 14 V
OK If ABS warning light does not blink even after Tc
and E1 are connected, ECU may be defective.

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.

DTC 11, 14 Actuator Motor Circuit
CIRCUIT DESCRIPTION
The actuator motor is operated by signals from the ECU. Acceleration and deceleration signals are trans-
mitted by changes in the Duty Ratio (See note 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, then.

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.

NG Check for short in all the harness and compo-
nents connected to the STOP fuse (See at-
tached wiring diagram).

2 Check actuator magnetic clutch.
PREPARATION:
(a) Remove cruise control actuator.
(b) Disconnect actuator connector.
CHECK:
Move the control plate by hand.
OK:
Control plate moves. (Magnetic clutch off)
CHECK:
(a) Connect positive + lead to terminal 5 and negative − lead
to terminal 4 of actuator connector.
(b) Move the control plate by hand.
NOTICE:
Do not connect the high tension cables to the wrong bat-
tery terminal.
You will damage the cruise control actuator.
OK:
Control plate does not move. (Magnetic clutch on)
NG Replace actuator assembly.

DTC 21 Vehicle Speed Sensor Circuit
CIRCUIT DESCRIPTION
The vehicle speed sensor signal is sent to the cruise control ECU as the vehicle speed signal.
The rotor shaft in driven by the gear of the transaxle.
For each rotation of the shaft, the speed sensor sends a 4−pulse signal to the combination meter.
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.
