100 miles into 80 mph Sunday ride, 'chec' message appears. Flicks back and to between clock and chec for a couple of miles (nowhere to safely stop), then temp.bars shoot right to the top and back down to normal after a couple of seconds. Finally I found somewhere to stop and had a 15 min cooldown. Rode 30 miles to home at 50 mph and same thing happened twice, stopped for cool down again.
Going to work on her tomorrow. Will have to remove fairing and tank to check fluids (no leaks evident). Does anyone have any other suggestions? Thermostat, fan?

It's not an overheat situation. When a CHEC occurs, the right bars light to call attention to it. Turn the kill switch off and the ignition on with a completely cold engine and you'll see that. Since the CHEC appears on a running engine, no safety switch is involved. It's usually the sidestand or kill switch that generates a CHEC and they cut power to the fuel pump. If the engine runs with a CHEC present, it means the ECM signal to generate a normal signal is not making it to the instrument panel. The large connector under the rubber cover in the fairing and the instrument panel connection itself are common areas of poor contact. Make sure your headlights work. They are often subject to poor connections in the same areas.

Whew !!! Thanks Greywolf. I will investigate tomorrow. Will it harm anything to run with this fault?

 

[greywolf]

It won't hurt anything unless something else goes wrong and you can't tell because you don't have functioning instruments.

That was my thought - thanks for the confirmation.
