NOTE
After replacing or disconnecting the driver
side power window regulator (motor), power
window main switch, battery and/or fuse,
make sure to execute the initial setting, (to
have the door glass closed position learned)
refer to “Power Window Main Switch
Initialization (Pinching Prevention Function
Model)”.

Pulse Sensor Circuit Diagram1) Remove driver side door trim referring to Step 1) to
3) of “Front Door Glass Removal and Installation”.
2) Remove power window main switch from driver side
door trim, and them connect connector to power
window main switch.
3) Disconnect power window motor connector.
4) Turn ignition switch to ON position.
5) Check that “SV” wire terminal voltage of power
window motor connector is 10 – 14 V. If voltage is
not satisfied, check power window main switch
circuit for open, short and high resistance. If circuit is
OK, replace power window main switch.
6) Connect power window motor connector.
7) Connect oscilloscope to power window main switch
connector terminals.
8) Check pulse sensor signal by using oscilloscope. If
pulse sensor signal is not satisfied, check pulse
sensor 1 and 2 circuit. If circuit is OK, replace door
window regulator (motor).

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
