ECU Reset issue
« on: July 03, 2012, 08:36:06 AM »
I just came home from a four day trip and about half a dozen times my ECU reset. I would start the bike up just fine and after about 2 seconds it would stall. Restart with no problem, but the clock, trip odometers, mileage etc now all read zero. Other than that the bike ran just fine. I haven't had a chance to look yet, but am going to start with the battery connections and then look at the ECU connector.

Does anyone know if the information displayed on the LCD screen is stored in the instrument cluster or it is stored in the ECU? Has anyone had a similar problem? Bike is 2008.

I've had this same issue happen with my 2011. What helped was to clean the grounds and the addition of adding some dielectric (sp?) grease at those connections. I still need to check a secondary harness ground that's under the fuel tank. Not exactly sure where it's located, but it was mentioned by someone else.

Hope this helps.

The data that you mentioned are all stored in the cluster.

Sounds like an iffy battery connection to me.

 When my bike was doing this (a little over a month ago), I pulled my battery all the way out, cleaned both + & -, cleaned & sanded the frame grounding point that's there near the battery, cleaned & sanded all of the terminal on the wires and applied dielectric grease to all electrical connections as I put it all back together.
 Up until yesterday, it hadn't happened again. But sure thing it did it again. But that "may" have been brought on by me going thru the engine mounting bolt torque sequence. By undoing the bolts and retightening them, I "may" have disturbed a grounding connection to one of the components. Not sure thou. But like I said in my earlier post, there is suppose (so I’ve been told) to be another harness grounding point somewhere under the tank. That grounding point "may" be less than ideal. So as soon as I get time and have little fuel in the tank, I'm going to try and find it. But up until then, I’ll just have to live with it resetting every once in a while.

Thanks. If that data is stored in the cluster, then I don't have to worry about the ECU.
