Not that one. There is another one named, literally, "Generic Warning Light." It covers low oil level, oil level sensor fail, time to change oil and a host of other things. Reading between the lines it looks like the rest of the message shows up in the "EVIC."
I will play with mine some, but since I do not have an illuminated lamp, probably can't help. All of the MOPAR products I have had you can get the trouble code by turning the ignition on and off 3 times in rapid succession, leaving it on the third time and the code shows up on the dash. Worked for all 3 of my Caravans, Intrepid and 2 Chrysler 300s (one of each body style, so really different cars). You don't need the spendy tool.
