Here is how to pull the cruise control dropout codes and what they mean. The module stores the last 8 dropout codes starting with the most recent dropout.

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 >>> 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

You now have 8 three-digit codes written on your arm....their meaning is:

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

Bob, Peppi copied and pasted the information from the DIY section of the forum found here:

Not sure how much diagnostic support he can provide beyond the cut and paste; hope he's an expert.

The 122 code would be the last code stored indicating the unit is picking up a power source from tha brake light system somewhere. What have you done to the bike recently? Any wiring changes or additions? Check over the plug pins on the cruise and the plugs themselves to see if all the pins are clean and making a good connection in the plug. Also look under the rear fender for the condition of the wiring harness above the tire for signs of abrasions from the tire and that it is fastened securly in the wiring loom under the fender, a common source of a problem.
