Low Fuel Warning Light Symptom DiagnosisS6RW0D9304005
NOTE
• Confirm that fuel meter is in good condition before referring to the following possible causes.
• When fuel level sensor circuit is open or short, fuel level meter indicates empty even if fuel tank
does not empty.
• The low fuel warning light comes ON when fuel level is lower than specification below.

Installation
Install fuel pump assembly referring to “Fuel Pump
Assembly Removal and Installation in Section 1G”.
Fuel Level Sensor InspectionS6RW0D9306005
• Check that resistance between terminals “a” and “b”
of fuel level sensor changes with change of float
position.
• Check resistance between terminals “a” and “b” at
each float position in the following.
If the measured value is out of specification, replace.

Oil Pressure Switch InspectionS6RW0D9306007
1) Disconnect oil pressure switch (1) lead wire.
2) Check for continuity between oil pressure switch
terminal (2) and cylinder block (3) as shown.
If check result is not as specified, replace oil
pressure switch (1).

BCM Reception Data
Theft Deterrent LightS6RW0DA201003
The information display or clock (1) of this vehicle includes a theft deterrent light (2) for the theft preventive purpose.
The BCM makes the theft deterrent light flash at certain intervals after the ignition switch is turned off until it is turned
on again. Also, DTCs stored in BCM can be checked by reading the flashing patterns of the theft deterrent light when
diagnosing troubles.
Security Alarm Description (If Equipped)S6RW0DA201005
Operation
The security alarm system provides a warning of an abnormal condition to those who are around. Its operation is as
follows. While the system is in the stand-by mode (when 20 seconds or more elapsed after the door is locked using a
keyless entry transmitter or door request switch), BCM monitors door lock status, door switch status and battery power
supply voltage. When it detects an abnormal condition (door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily), it activates the
warning buzzer (located in BCM), theft deterrent light, hazard warning relay and horn relay.
The security alarm system has 2 selectable modes.
• A mode: No operation
• B mode: Theft deterrent light blinks, hazard warning lights blink, warning buzzer (located in BCM) sounds and horn
sounds
