mannic Posted October 29, 2018 Share Posted October 29, 2018 Over the past couple of weeks, I've noticed my ride mode changes randomly. I typically just ride in STD mode, but have looked down on quite a few occasions and it will have switched on its own to A or B. While I don't necessarily mind if it switches to A mode, B mode always makes me feel like the bike has gone into limp mode. Is there something that's causing the ECU to change on its own? Thanks for the help! Link to comment Share on other sites More sharing options...
koth442 Posted October 29, 2018 Share Posted October 29, 2018 That's seriously strange. Might be a loose wire in the handlebar cluster. '15 FJ09 Link to comment Share on other sites More sharing options...
jonno12345 Posted October 29, 2018 Share Posted October 29, 2018 Would suspect the switch before the ECU, a short whilst you're off the throttle could cause it to change mode. Have you had it remapped? Link to comment Share on other sites More sharing options...

mannic Posted October 29, 2018 Author Share Posted October 29, 2018 It's a 2015. ECU has not been remapped. Link to comment Share on other sites More sharing options...
skipperT Posted October 30, 2018 Share Posted October 30, 2018 It's a 2015. ECU has not been remapped. That’s some strange behavior. The ECM should prevent the ride mode from being changed if the throttle is in ANY position but closed (road speed doesn’t matter). The only thing that comes to mind is a sticking mode switch on the RH handlebar. You might try taking the switch off the bars and making sure there isn’t a bunch of water or other corrosion causing a short. After that, you’ll need to pull the fairing and possibly the air box, depending on where the switch harness connects to the main harness - in order to get to the RH switch connector for further testing. (It might connect up under the windscreen trim as well, not sure) Other than that, paying attention to whether it happens regardless of throttle position will help troubleshooting. -S Link to comment Share on other sites More sharing options...

mannic Posted October 31, 2018 Author Share Posted October 31, 2018 I assume It is just a faulty button. Today on my ride to work, just the lightest thumb pressure on the mode selector caused it to change modes with a closed throttle. I'll have to pull that apart and see what I can find out.

ChrisConnor Posted October 26, 2019 Share Posted October 26, 2019 I know it was a year ago, but what did you find out? My '15 FJ-09 started doing the same about a week ago. Link to comment Share on other sites More sharing options...

Mine seem to change modes at will, without even touching the button. Then sometimes, the button does not change the mode. Thoughts? Link to comment Share on other sites More sharing options...
TTR Ignition Posted November 23, 2019 Share Posted November 23, 2019 The button is the most likely culprit. Pull and strip that switch cluster, and get in there with the WD40.
