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
