3. DTC CLEARANCE
(a) After completing repairs, the DTC retained in memory can
be cleared by removing the ECU−IG fuse for 10 seconds
or more, with the ignition switch off.
(b) Check that the normal code is displayed after connecting
the fuse.

When 2 or more codes are indicated, the lowest numbered code will be displayed first.
If the inspection ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue check.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
(*) When the vehicle speed decrease on uphill roads, the speed can be set again and driving continued. (This
is not a malfunction.)

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.

INSPECTION PROCEDURE
1 Check STOP fuse.
PREPARATION:
Remove STOP fuse from fuse block.
CHECK:
Check continuity of STOP fuse.
OK:
Continuity
NG Check for short in all the harness and compo-
nents connected to the STOP fuse (See at-
tached wiring diagram).
OK
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.
OK

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)
