Well the saga continues, MOCO told the tech to replace ECM to correct the cruise control problem, that did not do the trick. The tech has worked on it off and on for 4 days no luck. The service tech at Harley is going on vacation so they won't be working on the bike until he gets back.[that is not what I want to hear] I have to think that they have issues with there ECM'S and maybe I can get them to try another one today.Have a trip planned for the 1st of August so hopping to resolve ASAP.

For what it's worth, I seem to have cured mine by tightening the (little extra) slack on the idle cable.... that's not going to help yours though!

I too have had cruise control problems this summer.

I've had the following problems...
Won't engage at all
Will only engage when I push resume but not set
From being off I turn the switch to on and the green cruise light will be on with the bike not even running
Cruise will be set and the light will stay green but the bike will begin decelerating
I press accelerate and it will disengage the cruise control

Fortunately I'm still under warranty.

With the exception of the 3rd issue you have , mine is exactly the same . I to am under warranty but being as we have such a short good weather riding season I would really prefer to be riding no waiting for Harley  to get it right.

Just got word the cruise is fixed. It turns out the ECM was bad and the guide for installing a new Ecm had a error and they re installed and it works now. LOLO pass here I come.

I had a problem with my cruise control yesterday.  I was going about 45 mph when I tried to set it.  The green light came on, but the bike started slowing down as if I hadn't really activated cruise.  The green light was still on so I tried to bump up the acceleration a couple of times, but it was like the cruise was off.  Then the green light went out.  I tried to engage it again, but no green light.  After I got out on the highway I kept trying to engage it, but no luck.  For some reason I thought I would try turning the accessory switch on and suddenly I was able to use my cruise!  I tried turning the accessory switch off, and my cruise still worked.  (The accessory switch shouldn't be related to the cruise anyway!)   The rest of the day the cruise worked fine, but I can't help but believe the problem will surface again.

That's the way mine started. If it just flat quits working then it's a new ECM module for you. I thought mine was ready to go but the new ECM won't accept my SERT so the dealer has to ask Harley to pay for a new one as it was their defect that was the original problem.

Hi Guys

Work and other stuff has kept me off the forum for a while but I'm still riding!!

I just had the bike back from the dealer after the 30,000 mile service and some stuff that they missed when it was in for repair after a gentle front end collision - stop go traffic, guy in front stopped - I didn't...

Anyway

I'm all set for a 500 mile trip the next day and just take the bike out for a shakedown when I find the cruise has stopped working.

I don't make that much use of it normally but this was going to be a long haul on the motorway system so I was looking forward to engaging cruise and maintaining a good speed average.

The symptoms were that when I operated the set switch on the RH grip the lamp in the Tach would change to green momentarily but flick back to red immediately.

I suspected it had to be one of the overrides causing the problem but I also checked the error codes as per the Clymer Manual

Error code showed "sudden increase in revs detected" (or similar) but of course this could be a historic code that hadn't been reset some time previous.

The brake light switches seemed to be OK - no lamps on when they shouldn't be - so then I was thinking it might be a connection from the Tach or something

While the bike had been in for service, the dealer had been inside the fairing to replace the inner suppport brackets which were both broken in the "incident" and I was concerned that a connector had been dislodged or similar.

So I was just about to pull the fairing off and go through all the connections, when I got smart...

I logged on here, did a quick search - and came straight to Eqcons' (Jim's) problem.

I read through the general advice and comments and went back to the bike and disconnected the "throttle close switch" on the throttle cable in front of the tank.

Problem fixed. 

I guess as part of the "service" the throttle and idle cables were adjusted but the operation of the cruise wasn't checked.

Either that or the switch coincidentally went faulty...

Either way it's not an issue - I don't rely on shutting the throttle to deactivate - I always use front brake - and now I have cruise back 

Cheers

I'd check the idle cable adjustment, and re-do the procedure for calibrating the cruise control Dave - only takes a minute.

I always use the fronnt brake to turn it off too - except that for some reason, the brake light has stopped working off my fronto brake (still works off the back) so now using the throttle rolloff to disengage...

Be Careful, Mine was doing all of the above as well, Dealer replaced the module, still would do the same as before, While riding i started playing with the on/off switch, green light came on, set cruise and has worked ever since and have not turned the switch off since. But, I can have cruise set then all of a sudden it will take off on its own, Last time that happened i had to shut it down at 90 mph and the cruise is not suppose to go above 80.

They SHOULD pay for a new SERT for you, and I'm glad to hear they did.  I hope they also pay for a new dyno tune.

Guy's I know this is a really old thread, but I'm havingsimilar  Cruise Control problems on my 2010 Street Glide.  Will work for a while and then cuts out.  Historical data shows clutch disengaging the cruise and the dealer has indicated that they had broken the clutch pin when doing the 1,000 mile service, but they feel that's not the problem.

The dealer wants to blame it on the PCV that's installed as the cruise and 6 speed light both work when we drive without the PCV, but I've recently had a Power Commander send me a new PCV and have the same issues, so that rules that out in my mind.

The only thing I can think of here is that there is a wiring problem.  It goes into the dealer tomorrow, so I'm trying to get the dealer pointed in the right direction instead of just blaming the PCV.  Any thoughts?

Did the cruise control problem exist before your dealer did the service?  Did it show up right after they did the service?  If you can answer no to the first and yes to the second question, then no matter what the turkey's want to blame it on, they need to go back and figure out what they did to screw up the clutch switch or it's wiring.  The code shows the cruise disengagement was due to the clutch disengagement, correct?  There is a switch in the left handlebar switch housing that tells the ECM when the clutch is disengaged.  I have no idea what "pin" they broke, but if it was the pivot pin for the clutch lever (how the heck can you break that?), or anything related to the clutch lever, then the number one suspect is the clutch switch. 

BTW, assuming the pin they broke is in the clutch lever/master cylinder/switch housing area, did they mention why they were screwing with it?  There is nothing in the 1000 mile service that requires disassembling anything in that area other than the reservoir cover to check the fluid level.  Sure hope the "tech" wasn't taking it apart to lubricate the nonexistent cable.

The problem was happening before and after the 1k service.  Their test was to run the bike on the Dyno without the PCV (about 50 miles) and the cruise worked properly.  Then the plugged in the PCV and in about 15 miles the cruise disengaged, so they blamed the problem on the PCV and sent me on my merry way, back to my local guy who they don't like anyways.

It was about a week later that the dealership left me a VM saying that my clutch pin was in.  When I called them to tell them that I didn't order a clutch pin, nor did i know what a clutch pin was, they said that the tech had written "clutch pin damaged" on the inspection report and put one on order.  They could not confirm if it was damaged by them or before they did the service.  I was a bit pissed when they told me to be careful because my bike could now be started in gear.  I guess that's something I would have liked to have known a week earlier as I drove the bike home

Based on that, it appears that they at least understand that the clutch switch can be affected by whatever "pin" they're talking about.  Wonder why they don't also understand that the clutch switch will also affect the cruise control.  I'd still suggest getting whatever "pin" they're talking about fixed, and having them verify the clutch switch operation, before looking for problems with the PC.  The clutch switch is still the number one suspect, IMHO.
