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.

a) The temperature detected by the ambient air temperature sensor is lower than the indicated tem-
perature 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.)
Calibration Procedure For Compass
The difference between magnetic North and geographical North
can sometimes be great enough to cause false compass readings.
In order for the compass to operate accurately in a particular zone,
it must be calibrated using the following procedure.
1. Determine your location on the worldwide magnetic variation
map on next page. Record your zone number.
2. Turn the ignition switch to ACC or ON position.
3. Push the ``Mode'' switch continuously for ®ve seconds until the
current zone entry number is displayed.
4. Press the ``Mode'' switch repeatedly until the desired zone num-
ber is displayed.
Once the desired zone number is displayed, stop pressing the
``Mode'' switch and the display will show compass direction after a
few seconds.
CORRECTION FUNCTIONS OF COMPASS
The direction display is equipped with automatic correction func-
tion. If the direction is not shown correctly, carry out initial correc-
tion.
INITIAL CORRECTION PROCEDURE FOR COMPASS
1. Pushing the ``Mode'' switch for about 10 seconds will enter the
initial correction mode. The direction bar starts blinking.
2. Turn the vehicle slowly in an open, safe place. The initial cor-
rection is completed in one or two turns.
NOTE:
In places where the terrestrial magnetism is extremely
disturbed, the initial correction may start automatically.

sion stroke, as shown.
5. Remove the starter motor and wipe off the liquid gasket remain-
ing on the connecting part.
6. Install the ring gear stopper using the bolt holes for ®xing the
starter motor.
7. Remove crankshaft pulley using puller.
Be sure to securely attach puller jaws. Attach jaws only to the
rear side of pulley.
8. Remove front cover.

10. Remove timing belt.
After removing timing belt, do not turn crankshaft and cam-
shaft separately, because valves will strike piston heads.

SYSTEM DESCRIPTION
Intake door motor
The intake door motor is installed on the intake unit. Using a link it
opens and closes the intake door.
When RECIRCULATION switch is at REC, the ground line of the
motor is switched from terminalj
14toj13. This starts the motor
because the position switch contacts built into it make current flow.
When RECIRCULATION switch is at FRE, the ground line is
switched from terminalj
13toj14. The contacts turn along with the
motor. When they reach the non-current ¯ow position, the motor will
stop. The motor always turns in the same direction.

Operation
The auto ampli®er receives data from each of the sensors. The ampli®er sends air mix door and mode door
opening angle data to the air mix door motor LCU and mode door motor LCU.
The air mix door motor and mode door motor read their respective signals according to the address signal.
Opening angle indication signals received from the auto ampli®er and each of the motor position sensors are
compared by the LCUs in each motor with the existing decision and opening angles. Subsequently, HOT/
COLD or DEFROST/VENT operation is selected. The new selection data is returned to the auto ampli®er.
Transmission data and transmission order
Ampli®er data is transmitted consecutively to each of the door motors following the form shown in ®gure below.
Start: Initial compulsory signal sent to each of the door motors.
Address: Data sent from the auto ampli®er is selected according to data-based decisions made by the air mix
door motor and mode door motor.
If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decision. If the opening angle data is normal, door control
begins.
If an error exists, the received data is rejected and corrected data received. Finally, door control is based upon
the corrected opening angle data.
Opening angle: Data that shows the indicated door opening angle of each door motor.
Error check: Procedure by which sent and received data is checked for errors. Error data is then compiled.
The error check prevents corrupted data from being used by the air mix door motor and mode door motor.
Error data can be related to the following problems.
+Abnormal electrical frequency
+Poor electrical connections
+Signal leakage from transmission lines
+Signal level ¯uctuation
Stop signal: At the end of each transmission, a stop operation, in-operation, or internal problem message is
delivered to the auto ampli®er. This completes one data transmission and control cycle.
