Disconnect the level sensor from the reservoir and test to see if the warning goes off.  Get a new or known good multifunction sensor and plug it in, if the warning stops keep it, if not return it.  

If neither is at fault check wiring for continuity.  When this doesn't get any results pull the cluster, clean and coat all connectors with stabilant 22 or some such product.  If/when that doesn't work, price out a new autocheck board. BTDT
