Washer Fluid Indicator

Instrument panel cluster illuminates low washer fluid indicator when the following occurs:

• Body Control Module (BCM) detects a low washer fluid condition (signal circuit is low) for greater than 30 seconds. BCM sends a message to instrument panel cluster via serial peripheral interface (SPI) requesting illumination. BCM also sends a class 2 message to radio in order to activate an audible warning.
• Instrument panel cluster performs display test at start of each ignition cycle as commanded by BCM. Indicator illuminates for approximately 3 seconds.
