Anyone having issues with their cruise control with the PCV on the bike?  My cruise will work fine and then the 6th speed light will go out and the cruise will disengage.  After the bike is turned off and sits for a while the cruise will work for a while again and then the same problem. 

The cruise and 6th speed work fine without the PCV in, so the dealer has of course came to the brilliant deduction that it's the PCV causing the problem.  So, put in a new PCV and guess what...same problem.  Oh by the way, the dealer also informed me that the clutch pin was either broken already, or broken during the 1k service, could that have something to do with it?  Now the left blinker is out as well

Any ideas of what could be going on here?

First thought was that if they (or someone) got rough enough with it to break the clutch lever pin that the clutch switch might be boogered a bit also.  That wouldn't cause the sixth gear light to disengage though.  Don't have a clue.  Shouldn't have posted.  Never mind.

No problem, no one seems to know why this is happening.  I just talked to another dealer in WI that does PC instead of SERT on their bikes and he was confused as well, but felt that it wasn't the PCV that was causing the problem.  He offered to work on the bike if my local dealer wants to put the blame back on the PCV.

The weird part is that I don't seem to have the problem when running with just the stock ECM

12000 miles and no issue here.  I use hte cruise a lot.

I might have had two threads confused each asking about cruise issues.  Only realized that after posting in the other one.  In any case......


Thanks to Chip's knowing how his 09 works and Jerry asking the right questions to make us think of the right answers it now seems to be known your combination of losing cruise and sixth gear light could be caused by a problem with the little interlock switch at the clutch lever.  It will disengage cruise when you pull the clutch lever.  Chip just confirmed that it will cause the sixth gear light to go out immediately upon pulling the lever too.  So anything with that switch or its contact with the clutch lever is also worth checking.

If the clutch switch was an issue I would think that the stock ECM would fail the cruise at the same rate as with the PC-V hooked up. Let's face it, it has no idea the PC-V is there right?

[Badger Mike]

That's what I've been told, but I'm wondering if the PCV puts some additional electrical load on the system.  Just enough to make it trip

pcv has no control over cruise

Some time ago there was a thread dealing with this issue.  Try doing a search you may be able to find it.

pcv has no control over cruise

When I have my PCV in autotune the 6th gear light will go out (or on) just about every time I hit the throttle hard and the trims change. If I turn off
the auto tune function, it will go for about 10 minutes before the cruise and 6th gear light cycle either off or on. I think it's a data timing issue between
the PCV and the ECU.

I was chatting with Gary at TTS while inquiring about the CVO convertible. The 6th gear light didn't work after a flash. The light will go out when you flash with a SEST as well. He mentions how to fix the 6th gear light by reprogramming the Primary Ratio on the TTS, easy fix. Can't fix the light using the SEST. Another forum member here complained to HD about them selling a defective SEST product and HD gave him his money back. http://www.cvoharley.com/smf/index.php?topic=49972.0  He then purchased a TTS from Doc.

Here is the note from Gary...

We have seen this occasionally in the 2010 Dynas - the issue is that HD switched to a helical gear for the speedo pickoff, and the VSS sensor now occasionally misses pulses due to the different gear tooth shape.  Most have no issue at all; a few others exhibit the problem. 

The ECM uses the ratio of the VSS output pulses to engine RPM to compute which gear is selected.  When the pulses are out of the expected range, the 6th gear light does not activate and the cruise control may not work.

The workaround is to go into the MasterTune primary gear setting and reduce the ratio a bit.  The stock setting is 1.353 - try reducing this to 1.330 or so.  You can experiment a bit to find where it starts working "solidly"; some customers have set this as low as 1.324.

This will not affect the speedo calibration, only the 6th gear light.  The speedo calibration setting is completely separate form the primary gear calibration, although they both work off the same VSS sensor!

He was correct and this fixed our light issue. Since Bagger removed his PVC his light and cruise has been working fine. I can only estimate there are no other mechanical/electrical issues with his bike and the PCV is the issue. I am not aware of a "Primary Ratio" fix or adjustment on the PCV although I have read of this issue on several web site threads when using the PCV. No one has posted a fix at this time. Other issues that have caused the 6th hear light to go out was the clutch switch and/or a brake switch being touchy. I read there was a clutch slipping that caused this issues as well and a braided lever cover that would catch the wind and signal the brake lights thus turning off the cruise.

I hope this helps a bit even if to point you in the right direction.

Thank you, this is very helpful.  I'll give this a try and see if this solves the issue.  I'm asking the dealer to work on their end to check the cruise modules/connectors as my left blinker is shorting out as well.  Wondering if there is some moisture in the housing that is causing some issues in there.  Although, my cruise and 6th speed light seem to work fine without the the PCV, so the problems may not be related.

Took my bike back into the dealer last week for a number of issues:

1.  Wrong back rest installed - HD Warrantied it.
2.  Wrong back rest tore new seat...still waiting on HD.
3.  Left blinker malfunctioning, sometimes just goes on on its own, sometimes doesn't work at all.
4.  6th speed light and cruise control work intermittently w/ PCV hooked up, no problems without PCV.
5.  Broken clutch retainer pin...no idea how that happened?

Got a call from the dealer the next day saying that bike was done, come get it.  Drove the 30 miles to my dealer to pick the bike up only to find that they put on the new back rest, fixed the clutch pin and "could not duplicate" the other items.  This is the 3rd time the bike has been into the shop for the PCV/cruise issue.

When I questioned the service tech his comment was that nothing showed on the computer as a problem with the blinker, and that he was "tired of f$%*ing with the PCV/Cruise Control problem, that's my fault for using a bad product like the PCV."  Needless to say, I had a meltdown of epic proportions in the service area, so much that the service manager on duty walked me out of the service area to my car, where my wife was waiting for me.  I told him to keep the #$%@!%& $32,000 piece of crap until it was fixed.  The next day...no call, no apology, nothing.  The day after the head of the service department called to confirm that they are able to duplicate both problems, but can't figure out why on either of them.  He did apologize, recognized that he felt that the two items were unrelated (another push back on the PCV), but IMO, too little too late.

I even had the mechanic who installed the PCV call them to offer to help work on the problem together, and the Service Manager refused to do so.  So here I sit on a nice Sunday afternoon, no bike again...and no fix to my problems.

Sorry for the rant, but I'm more than a bit frustrated at this point   I think I'll give them until Wednesday this week and the go get the bike and try a dealer that is willing to work with me on both problems.  After a call to HD Customer Service.

[Mr. Wizard]

I think the blinker issue is in the hand control wiring.

Take off the PCV, sell it. Buy a TTS, do your own VTune calibrations and enjoy each mile with a smile.

[Badger Mike]

I'm close to doing that, just have a lot of $ and time put into the Power Commander, and I feel that we have a good map for it.  So I hate to waste either.
