Washer Fluid Level Indicator Malfunctions:

CIRCUIT DESCRIPTION
The Low Washer Switch is a discrete input to the Body Function Controller (BFC) which shall close when the washer fluid level is LOW. The BFC shall send out a Serial Peripheral Interface (SPI) serial data message to the Instrument Cluster to illuminate the low washer fluid indicator when the input has been active for at least 30 seconds. The indicator shall be commanded off by the BFC over the SPI serial data bus if the Low Washer Switch input goes inactive for at least 30 seconds.
