Auto-cruisecontrol unit13A0366Description of operation
When the brake pedal is depressed during constant-speedtravel, the stop light switch’s (NC) contacts for the cruise-control system open, with the result that the current to the
auto-cruise vacuum pump is interrupted, thus canceling the
constant-speed travel.
At the same time, moreover, the closing of the (NO) contacts
for the stop light results in the sending of the cancel signal to
the control unit, so that the auto-cruise vacuum pump current is
discontinued within the control unit, thereby canceling the
constant-speed travel.
The flow of current is from the sub fusible link
@I to fuse No. @
of the junction block, the stop light switch, and the control unit.Troubleshooting hint

The inhibitor switch also functions as the switch for the starter.If the selector lever is moved to the “N” position during
constant-speed travel, current flows to the control unit, inhibitorswitch, theft-alarm starter relay (vehicles with theft-alarm
system), starter motor, and to ground; the cancel signal istherefore input to the control unit, thus canceling the constant-speed travel.5Troubleshooting hint

OPERATION
TROUBLESHOOTING HINTS
-.l If the inside lock knobs of the doors are placedin the LOCK (or UNLOCK) position, the switch inthe door lock actuator will be “OFF” (or “ON”),
and the output transistor will be “ON” for 0.5
second according to the timer function in the
door lock control unit (or theft-alarm control unit).As a result, the LOCK side (or UNLOCK side) of
the door lock relay will be “ON”, operating the
actuators of all of the doors.
NOTE
The door lock actuator contains a PTC thermistor
to prevent damage caused by overheating of the
motor. If the central door lock is frequently used,the actuator may temporarily fail to operate. If it
returns to normal in a few minutes, it is not
defective.

2.One of the door lock actuators fails to operate.
l Check the door actuator which fails to
operate.Cannot be placed in the LOCK or UNLOCK
position by the inside lock knob on either driver’s
or front passenger’s seat side.0 Check the switch in the actuator.0 Check the door lock control unit (or
theft-alarm control unit).
