    John Deere 690ELC Excavator Instrument Panel Unidentified Warning Light

    Thank you! It's been driving me crazy that I couldn't match that icon with anything. The filter is about 600 hours since replacement and the oil was drained and replaced then. It makes sense the viscosity is probably on the upper end of the range with 15w40 and a few cold mornings.

    John Deere 690ELC Excavator Instrument Panel Unidentified Warning Light

To test, I start engine, put in "P" mode and operate about 2 minutes until the machine throttles back to idle while in use (not auto idle). The power setting remains in "P"...

    John Deere 690D LC System Controller Mode not working

    It is a 690E LC, not "D" I had a 690D previously, force of habit. I don't see a way to edit the original post though, unfortunately. I'll observe the mode and system voltage today and report back.

    Sorry about piggybacking, the original thread was never resolved here and my issue seems very similar. I will start a new thread now. :)

    I just purchased a John Deere 690DLC Excavator that has a similar issue to what the original poster described. It works useable with the computer control bypass switch on. When in computer control mode it will work properly for a few minutes before idling down to low idle and engine speed...
