HEADLIGHT HIGH-BEAM INDICATOR LIGHT
id091800013600
Purpose
• The headlight high-beam indicator light notifies the driver that the headlights HI are turned on.
Function
• When the instrument cluster receives the headlight HI signal sent from the BCM via CAN communication, it turns the headlight high-beam indicator light on.
Construction
• The headlight high-beam indicator light is built into the instrument cluster.
Operation
1. When the light switch is moved to any of the following positions, the start stop unit sends (1) a headlight HI signal to the BCM via CAN communication.
-
― Light switch at HEAD position and dimmer switch at HI position
― Dimmer switch at FLASH-TO-PASS position
2. When the BCM receives the headlight HI signal with the ignition switched ON (engine off or on), it sends (2) a headlight HI signal to the instrument cluster.
3. The instrument cluster turns the transistor on (3) based on the headlight HI signal.
4. When the transistor turns on, a ground circuit with the headlight high-beam indicator light is established, and the headlight high-beam indicator light turns on (4).
