FRONT FOG LIGHT INDICATOR LIGHT
id091800041100
Purpose
• The front fog light indicator light notifies the driver that the front fog lights are turned on.
Function
• When the instrument cluster receives the front fog light signal sent from the front body control module (FBCM) via CAN communication, it turns the front fog light indicator light on.
Structure/Construction
• The front fog light indicator light is built into the instrument cluster.
Operation
1. When all of the following conditions are met, the start stop unit sends (1) the front fog light signal to the front body control module (FBCM) via CAN communication.
-
― Ignition switched ON (engine on)
― Light switch position: TNS (parking lights) or HEAD
― Fog light switch position: F.FOG
2. The front body control module (FBCM) sends (2) the front fog light signal to the instrument cluster.
3. The instrument cluster turns the transistor on (3) based on the front fog light signal.
4. When the transistor turns on, a ground circuit with the front fog light indicator light is established, and the front fog light indicator light turns on (4).
