COMPASS AND THERMOMETERPFP:24835
System DescriptionEKS00BCE
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 mode switch when the ignition switch is in the ON position. The outside temperature will be displayed
in “°F”.
Selecting the indication range
Push the mode switch to change from °F → °C → OFF → °F.
The indicated temperature on the thermometer is not readily affected by engine heat. It changes only
when one of the following conditions is present.
–The temperature detected by the ambient sensor is lower than the indicated temperature on the thermom-
eter.
–The vehicle speed is greater than 20 km/h (13 MPH).
(This is to prevent the indicated temperature from being affected by engine heat during low-speed driv-
ing.)
–The ignition switch has been turned to the OFF position for more than 2 hours. (The engine is cold.)
DIRECTION DISPLAY
Push the mode switch when the ignition switch is in the ON position. The direction will be displayed.

Trouble DiagnosesEKS00BCG
PRELIMINARY CHECK FOR THERMOMETER
1. COOL DOWN CHECK
1. Turn the ignition switch to the ON position.
2. Cool down the ambient sensor 2 with water or ice.
Does the indicated temperature drop?
YES >> GO TO 2.
NO >> The system is malfunctioning. Refer to DI-28, "
INSPECTION/COMPASS AND THERMOMETER"
.
2. WARM UP CHECK
1. Leave the vehicle for 10 minutes.
2. With the ignition switch in the ON position, disconnect and reconnect the ambient sensor 2 connector.
Does the indicated temperature rise?
YES >> The system is OK.
NO >> The system is malfunctioning. Refer to DI-28, "
INSPECTION/COMPASS AND THERMOMETER"
.
NOTE:
The indicated temperature on the thermometer is not readily affected by engine heat. It changes only when
one of the following conditions is present.
The temperature detected by the ambient sensor is lower than the indicated temperature on the thermom-
eter.
The vehicle speed is greater than 20 km/h (13 MPH).
(This is to prevent the indicated temperature from being affected by engine heat during low-speed driv-
ing.)
The ignition switch has been turned to the OFF position for more than 2 hours. (The engine is cold.)

Symptom Possible causes Repair order
No display at all 1. 10A fuse
2. Ground circuit
3. Compass and thermometer1. Check 10A fuse [No. 12, located in fuse block (J/B)].
Turn the ignition switch ON and verify that battery positive volt-
age is at terminal 2 of compass and thermometer.
2. Check ground circuit for compass and thermometer.
3. Replace compass and thermometer.
Forward direction indi-
cation slips off the mark
or incorrect.1. In manual correction mode (Bar and
display vanish)
2. Zone variation change is not done1. Drive the vehicle and turn at an angle of 90°.
2. Perform the zone variation change.
Compass reading
remains unchanged.1. Vehicle speed signal is not entered
2. Compass and thermometer1. Check harness for open or short between combination meter
terminal 29 and compass and thermometer terminal 8.
2. Replace compass and thermometer.
Displays wrong tem-
perature when ambient
temperature is between
−40°C (−40°F) and
55°C (130°F). (See
NOTE above.)1. Check operation
2. Ambient sensor circuit
3. Vehicle speed signal is not entered
4. Ambient sensor 2
5. Compass and thermometer1. Perform preliminary check shown above.
2. Check harness for open or short between ambient sensor 2 and
compass and thermometer.
3. Check harness for open or short between combination meter
terminal 29 and compass and thermometer terminal 8.
4. Replace ambient sensor 2.
5. Replace compass and thermometer.
Displays SC or OC. 1. Ambient sensor circuit
2. Ambient sensor 2
3. Compass and thermometer1. Check harness for open or short between ambient sensor 2 and
compass and thermometer.
2. Replace ambient sensor 2.
3. Replace compass and thermometer.

Calibration Procedure for CompassEKS00BCH
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 cali-
brated using the following procedure.
CORRECTION FUNCTIONS OF COMPASS
The direction display is equipped with automatic correction function.
If the direction is not shown correctly, carry out initial correction.
INITIAL CORRECTION PROCEDURE FOR COMPASS
1. Pushing the Mode switch for about 10 seconds will enter the initial correction mode. The compass display
will begin to flash.
2. Turn the vehicle slowly in an open, safe place. The initial correction is completed in approximately 1.5
turns.
NOTE:
In places where the terrestrial magnetism is extremely disturbed, the initial correction may start automatically.
