Washer Fluid Level Sensor

Washer Fluid Level Sensor












General
The level sensor consists of a magnetic float arm and a sensor mounted in the washer fluid reservoir

SID sends B+ to the level sensor via pin 6, and the sensor is grounded at grounding point G30. At normal level, the float arm is level with the switch, the magnet in the float arm closes the circuit and pin 6 of the SID is grounded. At low levels, the circuit to ground is broken.

The function gives the CHECK message on the SID display (70 second delay). Check Messages

Diagnostics
If the circuit to the washer fluid level sensor is broken, the text message "WASHER FLUID LEVEL LOW" will be shown despite a correct washer fluid level.

If a short-circuit to ground occurs, the CHECK message will not be shown even if the washer fluid level is low.

The SID will not generate a diagnostic trouble code.
