any door is opened, or timer does not operate
properly.
Does room lamp turn on when room lamp
switch is in ``ON'' position?
Ye s
cNo
Check the following.
+Bulb
+10A fuse [No.
20,
located in the fuse block
(J/B)]
+Harness for open or
short between fuse and
room lamp
+Room lamp ground con-
dition
Does key warning chime operate prop-
erly?
Ye s
cNo
Check ``WARNING
CHIME'' system.
(Refer to EL-135.)
Does power door lock operate using driver
side knob lock switch?
Ye s
cNo
Check ``POWER DOOR
LOCK'' system.
(Refer to EL-204.)
CHECK ROOM LAMP OUTPUT SIGNAL.
1. Turn room lamp switch to ``DOOR''
position.
2. Disconnect control unit connector.
3. Check voltage between control unit ter-
minalj
17and ground.
Battery voltage should exist.
OK
cNG
Check harness for open or
short between room lamp
and control unit.
CHECK DOOR SWITCH INPUT SIGNAL.
1. Connect control unit connector.
2. Check voltage between control unit ter-
minalj

Trouble Diagnoses
PRELIMINARY CHECK FOR THERMOMETER
Turn the ignition key switch to the ``ACC''
position.
Cool down the ambient air temperature
sensor with water or ice, so that the indi-
cated temperature falls.
Does the indicated temperature fall?
Ye s
cNo
The system is malfunction-
ing..1
Leave the vehicle for 10 minutes, so that
the indicated temperature rises.
With the ignition key in the ``ACC''
position, disconnect and reconnect the
ambient air temperature sensor connector.
Does the indicated temperature rise?
Ye s
cNo
The system is malfunction-
ing..1
The system is OK.
.1: Check the system following ``INSPECTION/COMPASS AND THERMOM-
ETER''.
INSPECTION/COMPASS AND THERMOMETER
Symptom Possible causes Repair order
No display at all 1. 7.5A fuse
2. Ground circuit
3. Compass and thermometer1. Check 7.5A fuse [No.
9, located in fuse block (J/B)].
Turn the ignition switch ON and verify that battery positive
voltage is at terminalj
2of compass and thermometer.
2. Check ground circuit for compass and thermometer.
3. Replace compass and thermometer.
Forward direction indication
slips off the mark or incorrect.1. In manual correction mode
(Bar and display vanish.)
2. Zone variation change is not
done.1. Drive the vehicle and turn at an angle of 90É.
2. Perform the zone variation change.
Compass reading remains
unchanged.1. Vehicle speed sensor is not
entered.
2. Compass and thermometer1. Check harness for open or short between combination meter
terminalj
26and compass and thermometer terminalj8.
2. Replace compass and thermometer.
Displays wrong temperature
when ambient temperature is
between þ30ÉC (þ20ÉF) and
55ÉC (130ÉF). (See NOTE)1. Check operation
2. Ambient air temperature
sensor circuit
3. Vehicle speed sensor is not
entered.
4. Ambient air temperature
sensor
5. Compass and thermometer1. Perform preliminary check shown below.
2. Check harness for open or short between ambient air tem-
perature sensor and compass and thermometer.
3. Check harness for open or short between combination meter
terminalj
26and compass and thermometer terminalj8.
4. Replace ambient air temperature sensor.
5. Replace compass and thermometer.
NOTE:
+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 ``- - -''.
+The indicated temperature on the thermometer is not readily affected by engine heat. It changes
only when one of the following conditions (shown on next page) is present.

System Description
The warning chime is combined with the smart entrance control unit.
Both the ignition key and light warning chime will not sound, when ignition switch in the ON or START posi-
tion. (When power supply exists at smart entrance control unit terminalj
12.)
IGNITION KEY WARNING CHIME
With the key in the ignition key cylinder, the ignition switch in the OFF or ACC position, and the driver's door
open, the warning chime will sound. A battery positive voltage is supplied
+from key switch terminalj
1
+to smart entrance control unit terminalj1.
Ground is supplied
+through driver side door switch
+to smart entrance control unit terminalj
7.
LIGHT WARNING CHIME
With ignition switch in the OFF or ACC position, driver's door open, and lighting switch in 1ST or 2ND position,
warning chime will sound. A battery positive voltage is supplied
+from lighting switch terminalj
12or daytime light control unit
+to smart entrance control unit terminalj
14.
Ground is supplied
+through driver side door switch

Power door lock/unlock operation by lock knob
+With lock knob on driver or passenger door setting to LOCK while all doors are closed will lock all doors.
When one or more door is opened, with lock knob on passenger door setting to LOCK will lock
passenger door only. (Power door lock system will not operate.)
+With lock knob on driver or passenger door setting to UNLOCK while all doors are closed will unlock all
doors.
Lock knob operation cannot control super lock.
Key reminder system
+If the ignition key is in the ignition key cylinder and any door is open, setting lock/unlock switch or lock
knob on driver or passenger door to ``LOCK'' locks the door once but then immediately unlocks all doors.
System initialisation
+System initialisation is required when battery cables are reconnected. Conduct one of the followings to
release super lock once;
Ð insert the key into ignition key cylinder and turn it to ON.
