System Wiring Diagram

Operation

1. When the washer fluid level in the washer tank decreases, the BCM detects (1) a washer fluid-level sensor on signal.

2. The BCM sends (2) a low washer fluid level warning light on request signal to the instrument cluster via CAN communication based on the washer fluid-level sensor on signal.

3. The instrument cluster turns the transistor on (3) based on the low washer fluid level warning light on request signal.

4. When the transistor turns on, a ground circuit with the low washer fluid level warning light is established, and the low washer fluid level warning light turns on (4).
