Construction

• The LDWS warning alarm sounds using the buzzer built into the instrument cluster.

Operation

1. The instrument cluster receives (1) a warning sound request signal from the forward sensing camera (FSC) via CAN communication.

2. The instrument cluster turns the transistor on (2) based on the warning sound request signal.

3. When the transistor turns on, a ground circuit with the LDWS warning alarm is established and the LDWS warning alarm sounds (3).
