Check Engine Light Came On

I am posting this hoping that the learned collective on this forum can help me figure this out without having to take it to the dealer. So. A few weeks ago I rode my 2013 K1600GTL with 20,500 miles (bought from the dealer in November last year) to work. Fairly cool in the morning (mid-50's) and warm in the afternoon. No issues riding to work. Leaving work with the temp in the mid-80's, the check engine light came on. Not flashing and no perceptible change in sound or performance. Got home and checked it over. Oil is good. The 18K service was done before I bought the bike from the dealer. This past weekend I was thinking about it so I started it in the garage and let in run until it warmed up. No light. I didn't ride it at that time. Fast forward to yesterday. I rode to work in the morning with similar morning temps as before and no engine light. Left work with temps in the mid-80's again and the engine light came on. I need to mention it does not come on at the start. Only after riding for a bit. Then it stays on. Again, no perceptible change in sound or performance. The engine is running at the same temperature in the morning as it is in the evening. The only difference is the outside ambient temperature. Why would that cause the check engine light to illuminate? What else could it be? I do not have a GS911 and would prefer not to buy one if I don't have to. So before I take it in, what could the cause be? Any thoughts?

How old is your battery?

Is it still the factory AGM battery?

Some people see the gas tank as half empty. Some see it as half full.
All I care is that I know where the next tankful is coming from...

Ken, I really don't know. It starts very well and very quickly even after sitting for a month. So I think it's pretty good but. not entirely sure. Why would that cause the Check Engine light to illuminate and only in the afternoon and not in the morning?

When I've had batteries start to go bad, sometimes the bike can read the voltage dip and flag it, even if everything looks OK to the rider. It also makes it harder to restart a warm bike.

Your best bet is still a dealer or GS-911 reading.

Maybe someone near you has a GS-911 they can use to check your fault codes?

Is there anybody on the forum that lives in the Tucson area? That has a GS911 that can be used to check codes?

You need to pull the codes either from the dealer or GS911wifi.

As Duane said you need to get the codes one way or another. There's hundreds of things it COULD be and only guesses if you don't have a place to start from.

Without a GS-911 or the dealer computer, I suspect you have an intermittent ignition coil failure. I experienced the same symptoms you described - solid check engine light and no noticeable degradation in performance. It was an intermittent coil failure. Outside temperature played no factor in the fault.

I get I need to take it in. I guess I was hoping that one of you would say "Hey, that happened to me and this is what it was." Give me a place to start.

A great time to both take it to the dealer (still under warranty) and buy a GS911. In my case it was a faulty side stand micro switch. In your case it could be one of so many causes, only the bike will tell you what’s wrong
