Update on "Coolant Low" message. After checking the Coolant level sensor to see if it read the correct Ohm reading (which it did), I proceeded to order the Windshield Washer level sensor. I spent a couple hours pulling the wheel well and removing the sensor wire to the Windshield Washer (not easy to get to). I connected my new sensor (without installing in washer bottle) and observed the dash messages as the senor level float was moved up and down. The messages displayed correctly along with the "Coolant Low Check" message. After observing the correct messages I ruled out the Windshield Washer level sensor as being the problem. I then ordered the Coolant level sensor and installed the new part. The "Coolant Low check" message no longer appears. I would recommend that you skip the ohm meter check of the coolant sensor and just replace the part. Save a lot of unnecessary work.
