2007 Road Glide - Cruise will not work
Midway through my AZ Bike Week vacation, my cruise stopped working. I have searched the forums and tried some things, to no avail.
I am getting a code 122 when I do the Cruise Diagnostic procedure. The bike allows me to do the cable lash set procedure; the bike revs up and does what it is supposed to do. I have disconnected one of the roll off plugs and it sitll didn't work; do I need to unplug both? Front and rear brake switches are working fine, no sticking. Any other suggestions? Thanks in advance. |
have you dissambled the throttle controls in the past?
Even if your brake lights work it don't mean that the microswitch in the front brake lever ain't broke.

They tell you why the cruise control disengaged. 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 Source: Private |
Need to find out what the code 122 is. Try removing both connections to roll off switch, I can't remember if it is a NC or NO switch. When you you say front and rear brake switches work fine, how did you check them?
|
As uweldit post shows 122 is brake is applied. I would check brake switches again.
|
The switches seem to function fine as the brake light works normally. I have broken the front brake switch before and the brake light was stuck in the on position.
|
Trust me, been through this B4. 122 means bad switch.
That bugger damages easily. My brake lights worked perfect but cruise would cut out even though green cruise indicator was still on. Your choice now, good luck! |
Another thing to consider, on my 07 RKC the switch wasn't bad BUT the plunger in the front brake master cylinder was sticking in just enough to not fully engage the switch all the time. Like when you were at speed and the wind was pushing the lever back just enough to disengage the switch. I didn't have cruise but the damn thing had brake lights when parked.
Had to rebuild the master cylinder. |
I had a problem on my 05 and 07 RG. The rear brake switch would close and not open if the air temp was in the high 80's. I think, somehow, the residual pressure in the rear was too high. The dealer replaced the pressure switch in both cases.
