Checking the Washer Fluid and Coolant Levels

1 If they are in proper working order the right message should appear on the SID unit display when the level sensor switch is open.

WASHER LEVEL LOW

COOLANT LEVEL LOW

If the BLACK PANEL is activated the display should light up.

2 Connect a ISAT Scan Tool and select the "READ VALUES" menu and then "INPUT SIGNALS".

3 Unplug the connector of the sensor that is suspected of being faulty. The corresponding message should now be activated on both the SID and Scan Tool.

If this works, the sensor is faulty and must be replaced.

If no message is displayed, continue with point 4.





4 Check the wiring for continuity/shorting by taking a reading across:

SID Function Sensor
pin pin

1 Washer fluid 1
level

3 Coolant level 1

Note: If a message is always displayed, check the sensor's grounding cable.
