LDWS INDICATOR LIGHT (GREEN)/LDWS WARNING LIGHT (AMBER)

id092200029700

Purpose

LDWS indicator light (green)

•  The LDWS indicator light (green) notifies the driver of the vehicle lane lines being recognized or that the vehicle may be departing from its lane.

LDWS warning light (amber)

•  The LDWS warning light (amber) warns the driver that a malfunction is occurring in the Lane Departure Warning System (LDWS).

Function

LDWS indicator light (green)

•  The instrument cluster illuminates the LDWS indicator light (green) based on the system condition display request signal sent via a CAN signal from the FSC.

•  The instrument cluster flashes the LDWS indicator light (green) based on the warning indication request signal sent via a CAN signal from the FSC.

•  The flash pattern of the LDWS indicator light (green) is as shown in the figure.

LDWS warning light (amber)

•  The instrument cluster illuminates the LDWS warning light (amber) based on the system condition display request signal sent via a CAN signal from the FSC.

•  The instrument cluster flashes the LDWS warning light (amber) based on the malfunction indication request signal sent via a CAN signal from the FSC.

•  The flash pattern of the LDWS warning light (amber) is as shown in the figure.

Operation

LDWS indicator light (green)

1.  The instrument cluster receives (1) the system conditions indication request signal or warning indication request signal from the FSC via the CAN signal.

2.  The instrument cluster turns the transistor on (2) intermittently for a warning indication request signal and continuously for a system conditions indication request signal.

3.  When the transistor turns on intermittently, the LDWS indicator light (green) flashes (3) and when it turns on continuously, the LDWS indicator light (green) illuminates (3).

LDWS warning light (amber)

1.  The instrument cluster receives (1) the system conditions display request signal from the FSC or the system malfunction indication request signal via the CAN signal.

2.  The instrument cluster turns the transistor on (2) intermittently for a system malfunction indication request signal and continuously for a system conditions indication request signal.

3.  When the transistor turns on intermittently, the LDWS warning light (amber) flashes (3), and the when it turns on continuously, the LDWS warning light (amber) illuminates (3).
