Low Washer Fluid Indicator

Range: ON/OFF
This data indicates what message is being sent from the BCM to the instrument cluster in order to control the low washer fluid indicator illumination. When the BCM is commanding the low washer fluid indicator to be illuminated, ON is displayed. When the BCM is commanding the low washer fluid indicator not to be illuminated, OFF is displayed.

The low washer fluid switch is attached to the washer solvent reservoir. This switch sends a discrete input to the BCM that will close (provides a ground) when the washer fluid level drops below the switch for at least 30 seconds. The BCM in turn sends a SPI data message to the instrument cluster in order to illuminate the low washer level fluid indicator. The low washer level indicator will be commanded OFF when the low washer level switch input goes inactive (fluid level satisfactory for 30 seconds). In the event of a SPI data loss, the low washer level indicator will not illuminate unless the low washer level indicator was illuminated prior to the SPI data line failure.
