System Description
CIRCUIT OPERATION
[Example]
Aiming switch ``0''
+When the aiming switch is set to ``0'', the motor will not start.
This is because the power terminals are positioned at the non-
conductive section of the sensor's rotary unit.
Aiming switch ``0''®``1''
+When the aiming switch is moved from ``0'' to ``1'', the sensor's
conductive section activates the relay. Power is supplied
through the relay to the motor. The headlamps will then move
in the ``DOWN'' direction.
+The motor continues to rotate while the rotary unit of the sen-
sor moves from point A to point B.
+The power terminals will then be positioned at the nonconduc-
tive section, disconnecting the power to the motor. The motor
will then stop.
Aiming switch ``1''®``0''
+When the aiming switch is moved from ``1'' to ``0'', the sensor's
conductive section activates the relay. Power is supplied
through the relay to the motor. The motor will rotate to move the
headlamps in the ``UP'' direction.
+When the rotary unit of the sensor moves from point B to point
A, the motor will stop.

System Description
This unit displays the following items:
+Earth magnetism and heading direction of vehicle.
+Outside air temperature.
+Caution for frozen road surfaces.
OUTSIDE TEMPERATURE DISPLAY
Push the switch when the ignition key is in the ``ACC'' or ``ON'' position. The outside temperature will be dis-
played in ``ÉF''.
+Selecting the indication range
Push the switch to change from ``ÉF'' to ``ÉC''.
+When the outside temperature drops below freezing point, ICE is displayed on the unit.
+When the outside temperature is between 55ÉC (130ÉF) and 70ÉC (158ÉF), the display shows 55ÉC
(130ÉF).
+When the outside temperature is lower than þ30ÉC (þ20ÉF) or higher than 70ÉC (158ÉF), the display shows
only ``- - -'' though it is operating. This is not a problem.
+The indicated temperature on the thermometer is not readily affected by engine heat. It changes only when
one of the following conditions is present.
a) The temperature detected by the ambient air temperature sensor is lower than the indicated temperature
on the thermometer.
b) The difference in temperature detected during a period of 40 seconds is less than 1ÉC (1.8ÉF) when vehicle
speed has been greater than 24 km/h (15 MPH) for more than 100 seconds.
(This is to prevent the indicated temperature from being affected by engine heat or cooling fan operation
during low-speed driving.)
c) The ignition key has been turned to the ``OFF'' position for more than 4 hours. (The engine is cold.)
DIRECTION DISPLAY
Push the switch when the ignition key is in the ``ACC'' or ``ON'' position. The direction will be displayed.

HEADLAMP WIPER MOTOR CHECK
When wiper motor is locked, a protective circuit built into
wiper motor activates to stop wiper motor. If wiper motor will
not restart even after cause of problems has been eliminated,
turn ignition switch OFF and leave it off for approx. 1 to 3
minutes.
1. Turn headlamp wiper switch OFF.
2. Connect ohmmeter and check continuity.
