My cruise control stopped working on my 08 RG today(I have almost 3k miles). I noticed yesterday I had to be running above 50 for it to engage then this morning I was cruising along about 65 with cruise set, suddenly it shut down and now won't reactuate. Red cruise indicator light is on but the green light doesn't activate. The service manual has virtually no mention of the cruise I can find. I know my bike is still under warranty but I don't trust the dealers around here at all plus they are gonna want to keep it for days also a pain to get it there, closest dealer 50 miles! I discounnected the battery and removed the maxi fuse for awhile, checked all fuses no change. I know the cruise on the FBW bikes is in the ecm now but I'll be damned if I can even think of a way to start troubleshooting this thing. The check engine light is working normally. does this mean there are no codes? I have checked to make sure the brake lights aren't activated.
Anyone got any ideas? I have serious carpel tunnel and other wrist probs so I have to have my cruise!
TIA

 

Here is how to pull the cruise control dropout codes and what they mean. They tell you why the cruise control disengaged. The module stores the last 8 dropout codes starting with the most recent dropout. You may also need to do a cable lash adjustment.

To invoke the readout:

Engine OFF, cruise switch OFF

Push cruise set/resume switch to SET and HOLD it there while switching to IGNITION (do NOT start engine)

RELEASE the set/resume switch and watch the cruise enabled lamp....it will flash out 3 digits encoded as a series of pulses in the following pattern &gt\\;\\; the first digit is string of 1/4 second flashes, then a one second pause\\; then the second digit is string of 1/4 second flashes, then a one second pause\\; then the third digit is string of 1/4 second flashes and it stops.....write down the number of flashes in each of the three segments and you will get a three digit code

If you want to verify the flashes you just saw, then push the switch to RESUME and it will repeat the three digit code that you just read.....

To get the next three digit code that is stored, push the switch to SET and three more digits will be pulsed out in the same format as above.....continue advancing the codes by toggling to the SET (or verify them using RESUME)

There are 8 codes stored and once the buffer is empty, the cruise engaged lamp stays on solid.........if you want to repeat all 8 again, then toggle the switch to SET

To exit the readout mode switch the ignition to OFF

111 No Codes, memory clear
112 Throttle roll off
113 Cruise switch turned off
122 frt or rear brake applied
211 Coast interval longer than 6 seconds (S/C button)
212 speed dropped below 30 mph while s/c button held
213 speed below 26 mph or above 90 mph
221 speed drops more than 15 mph below speed set point
222 speed decrease exceeds 20 mph per second
223 vehicle speed sensor input
231 rpm exceeds 5000
232 tach signal lost
242 high rate of engine rpm change (e.g., hit ice or slipping tire)
341 low voltage
internal failure if code 311, 312, 313, 321, 323, 331, 332, 333, 342, 343, 351, 352, 353, 361, 362, 363, 371, 423, 432, 777

 

Thanks for the reply Glide, This method does not work to pull codes from my bike. Bike is 08 FBW, I notice that you mentioned cable lash so maybe you are looking at the older bikes. The 08 FBW bikes cruise is handled through the ECM instead of having a seperate module for cruise like the&nbsp\\;older models. Using the method above does not illuminate the cruise light nor does it cause any other&nbsp\\;reaction.&nbsp\\;

 

Check the 2 wires that hook to the brake switch. I had one broken and it quit working on mine too. Does your brake light work?

 

I had a similar problem the dealer needed to hook the bike up to a computer and bascially reboot the computer. Also if the cruise unit thinks your brakes are being applyed cause of a pinched wire cruise will not engage. Dealer put new bars on my RK and pinched a wire crusie didnt work for awhile took bike in for first service found the pinched wired fixed it flashed the computer works great now.

 

I found it guys, thanks for all the ideas. It was the Dakota Digital speedo recalibration unit. No matter what Dakota Dig tells you, I spoke to them on several occasions,&nbsp\\;IT WON'T WORK on an 08 fbw bike without messing up the cruise control! The module works GREAT for recalibrating your speedo but on the new bikes, I'd wait for a re-engineered unit to come out! Anyhow, removed it(it was hardwired, whet a major PAIN!) and the cruise works fine!

&nbsp\\;Thanks for the feedback, I was just looking at the Dakota Gadges today. Guess I'll wait awhile.
