Same old problem!!
Hey DYNA riders. I am still searching for a problem with my 2012 DYNA Switchback A,B and Range trip meter indicators not reading accurate. I can reset both A and B readings to 0 and within minutes, they both go to a reading of 3812 (more or less) . Does the same thing whether the engine is running or not. I have left the battery disconnected for days and when reconnected, the meters do the same thing. The Range meter does something similar. The speedometer seems to be accurate when riding the bike. The bike cranks and runs good and I have cleaned all the ground connections that I can find and or course, rechecked the battery connections. There are no DTC codes. Bought the bike used and have put several thousand miles on it before this started happening.. I have also disconnected both the ECM and BCM connectors and cleaned the pins and the battery is relatively new but I did have it load tested and it came out good. I figure that either the speedometer, ECM or BCM might be bad. Checked the speed sensor also. Which do you guys think? The modules are about $300.00 each, so too pricey to just replace, and can the modules be swapped with another bike to test???Not sure about speedometer price. Do you guys have any SERIOUS suggestions? I've already heard plenty of BS suggestions about it but will probably get some more. Thanks

What a strange problem. Electrical issues are usually the hardest to track down. Wish I could offer some more help but I really have no idea about this one, you've already checked the stuff I would have suggested. Might be worth checking with the dealership maybe it's something common they've seen?

Somethings amiss with your ECM, that's where all the data is stored that gets displayed. The fact that it keeps changing back... means it's not any connection you have, but in the ECM itself.
