Dubuque Posted October 23, 2006 Share Posted October 23, 2006 I was coming home today from a 700 mile weekend trip and the gear indicator display on my 2004 R1150RT started acting up. Gears 1 thru 3 displayed just fine but when in 4th gear the display would cycle between 0 and 4 about twice per second, when in 5th gear it would flip between 1 and 5 and when in 6th gear it would flip back and forth between 2 and 6. Occasionally it would just stay on one or the other number for a few minutes. When I would shift it would display the right gear for a few moments then start acting up again. Anyone have this problem? Is this a know problem? With a dealer fix? Thanks for any info! Tom Link to comment
Ken H. Posted October 23, 2006 Share Posted October 23, 2006 The gear position sensor/switch on the rear of the transmission that sends position info to the RID has been problematic. Look there first. Link to comment

Tom Tom, It is 'probably' Item #15 here: http://tinyurl.com/tqnzx Not knowing your warranty "in service" date, it might be covered under warranty. I'm sure Iron Horse will take care of you. You have a 'slow' or dirty 4-bit on the switch. The switch is just a 4 position encoder..... 1 2 3 4 .....they use the binary combinations (1=1st gear, 2=2nd gear 1+2=3rd gear 4=4th gear 4+1=5th gear 4+2=6th gear) As you can see, your 4-bit is dropping now and then.

Dubuque Posted October 24, 2006 Author Share Posted October 24, 2006 Thanks guys! I was hoping that someone would be able to ID the sending unit and its location. The link was just perfect Mick , thanks. I am still under warranty and will call Iron Horse tomorrow but now I know what to tell them to look for and in case it is not a warranty item I can do it myself. As you can tell I am not an IT guy! But can do some wrenching. Tom Link to comment
EricJRW Posted October 24, 2006 Share Posted October 24, 2006 Let us know how it goes... Having an '04, I'm curious. Thanks Link to comment
Dubuque Posted October 25, 2006 Author Share Posted October 25, 2006 I have an appointment with my dealer (Iron Horse) this Friday and they said over the phone that as long as the bike is under warratny and it is a part that failed they will cover the repair. We'll see. It has been my experience that something like this will work just fine while at the dealers but go haywire as soon as I leave. Thanks again for the info guys. Tom Link to comment
bmwmick Posted October 25, 2006 Share Posted October 25, 2006 Tom, I'm sure John will take care of you. Recreating the error is 90% of the battle. Just tell him the exact conditions it failed under. Mick Link to comment
groundeffect Posted October 25, 2006 Share Posted October 25, 2006 The exact same thing happened to my 2002rs at around 20k miles....turned out to be a dirty connection from the tranny output wiring. A little hard to get at..but an easy fix! Link to comment
