I took my Brutale 910 for a ride yesterday. Everything seemed normal at first. After a few kilometres the coolant temperatures on the display just went berserk in a couple of seconds. It went from normal operating temperatures to 120 C, and then to the three blinking lines that indicate that the temperature is very low. I stopped immediately, but there was no indication of a high engine temperature, or lack of coolant. The ride home went well, but with the three lines indicating very low engine temperature still blinking.

When I took the bike out later in the evening, the 3 blinking lines wouldn’t go away even if normal engine temperature should have been reached after a few kilometres.

Has anyone else experienced this, and know the cause of the problem?

Yep....failed sensor...that's where i would head. Maybe just a bad wiring connection.

I would also try dissconnecting the clocks for 30 seconds. I had something similar on my KTM and that cured it. Failing that then as the others have already said prob a faulty sensor or connection

hi - did anyone else have any more thoughts / cures over this ? my 989r just over a year old, 3k has done exactly the same today, starting flashing unrealistic and erratic temp then went to three flashing lines where it has stayed all day..... bike still under warranty but pain in the neck to take to nearest dealers so would like to fix it myself if poss.........., thanks amanda

my 1078 did this at 2500k's. It went crazy jumping all over the place then finally just gave up and wouldn't show anything. It was the temp sender, took nearly 3 months to get a replacement, but finally came in and all is good again.

BTW, not sure on your 910 or 989, but on the 1078, I have only one sender that is next to the thermostat in the head (it has 4 leads coming straight out of it that then go into a plug about 60mm away. The 910 has two sender units from what I've seen, one in the head (same position as mine) and an extra one in the radiator tank. I suspect it is the one near the thermostat that is the problem as that's the one that controls the temp guages (radiator tank switch controls the thermo fans - easy way to check is to see if your fans coming on normally).

Color pic is mine (1078) showing 4 leads coming out of it, diagram is probably what your's looks like.







Hope that helps.
