Washer fluid level sensor

The junction box electronics monitor the washer fluid level sensor from terminal status "terminal R ON". The washer fluid sensor is integrated in the washer fluid reservoir and is switched to ground.

The junction box electronics receive a low signal when the washer fluid reservoir is full. The switch opens when the fluid level in the washer fluid reservoir drops below a certain level. The low signal changes to a high signal. The junction box electronics consequently generate a message indicating the low level in the washer fluid reservoir.
