Low Wash Indicator

The amber LOW WASH indicator turns on in order to indicate to the driver that the washer fluid level is low. The low washer fluid level switch is a discrete input to the BCM which closes when the washer fluid level is low. The BCM commands the instrument cluster to illuminate the indicator when the input has been active for a calibratable time (at least 30 seconds). The BCM commands the instrument cluster to turn the indicator off, if the switch input goes inactive for a calibratable time (at least 30 seconds). If a Class 2 data link fails, the LOW WASH indicator does not illuminate unless the indicator was illuminated prior to the Class 2 data link failure.
