It is getting worse , sometimes the cruise control is completely without function , then i turn of the ignition and start again and mostly the cruise control does work correctly . Talked with the dealer he wants to order and change the speed sensor , to try whether this is the fault . Anybody has the same problem ?

Do you lose speedometer when you lose cruise control?  Speedo sensor signals both.

done a diagnostic check for p-codes??

No speedometer loss
no diagnostic code check yet ( can i do this on my own or just the dealer ? How ? )

[5.56mm]

It happened to me too!  I'm thinking maybe it's something with the Power Commander V... I don't know.

No speedometer loss
no diagnostic code check yet ( can i do this on my own or just the dealer ? How ? )

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting should illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.

9 - Press and release the odometer reset button to continue to the next module.

10 - Turn Ignition switch to OFF.

Holy cow . 

[TN]

Holy cow . 

don't involve religion in this.

so you get any codes?

TN

[Highjagger]

i will try tomorrow

[kraut]

usual cause would be faulty wiring - btw: who installed your ape hanger?

[Highjagger]

But when there would be a loosely wiring then the problem would appear often and not so rare i guess but i am thinking about this possibility too .

[Highjagger]

The cruise control lost completely its function and i noticed that my rear brake light allways was illuminated (during a one-week tour in the mountains of italy-switzerland and france) , my guess was that the brake contact at the hand control got a damage (maybe when they swapped the handlebar to the ape ), we found the Grenoble dealer , stopped , bought a t-shirt and asked the tech whether this could be the reason and he cut the wiring at the hand-brake-contact (he had no contact-switch at the shop available to change it ), now the cruise control did his work again , the brake light only lights up by using the foot-pedal . Back at home i told this to the ape-change-garage but the hand-brake-contact-switch are in backorder , they should arrive maybe next week.
He told me that they will test whether the switch is really damaged or just not placed exactly at the inner of the hand-control (this also could be cause a malfunction ) but i guess that in this case the brake-light would never lights up, in comparison to the fault at my bike where it allways lights up.
What is the usual malfunction when damaging the hand-brake-switch by changing the hand-controls not correctly ?
Allways no brake-light or allways brake light ?

[Highjagger]

Now i made the diagnostic check and found the following codes :
P 1511
P 2107
PN 31844-09 ( don`t know whether this is a code or something else )
no rSP (what does this mean ) ?

Does somebody know the meaning of the codes i found ?

After clearing the codes and fired up the engine and check again there where no codes to find besides this "no rSP"

[04se103]

P1511 Throttle actuator control power management failure of throttle control actuator
P2107 EFI Module Processor Internal Fault
No Rsp" (no response) will also appear if the run/off switch is in the off position when doing this procedure.

[Highjagger]

P1511 Throttle actuator control power management failure of throttle control actuator
P2107 EFI Module Processor Internal Fault

Does this mean anything important or do i have to worry about (the codes did not return after clearing ) but where did they come from ( perhaps when the dealer did the supertuner and the dynos ) ? Thank you for the quick answer .

[Highjagger]

You may be on the right track. My friend had the exact same problem, no cruise, rear brake light always on. It turned out to be a broken brake switch inside the right hand brake assembly. He had it replaced, cruise and brake lights now work perfectly. 

replaced on warranty ? Is there an issue with the hand brake switch ?

Probably were  historic codes

[Cvostu]

I had a probelm with my cruise control on my 04 and even replaced the "cruise set/resume" switch on the handle bar. After soldering it all in and putting it all back together, it still didn't work.. That was 3 hrs of a waste and a 60 dollar switch. I then tried unplugging one of the wires that are connected to the thottle cable down by the gas tank.  That connection lets you roll the throttle forward to turn off the cruise. Well I did that and now it works perfectly.  I know that was my problem all along now. Oh well,  I had nothing better to do on a lovely Saturday afternoon anyway.

[Highjagger]

Thank you , i will try my best and ask about the warranty for this switch .

Sounds to me like whoever swapped out your handle bars did not deal with the brake lever switch correctly. There is a little button/switch inside the brake lever assembly that gets depressed when you grab the brakes. This switch is what cancels cruise if it happens to be on. I'm not sure about the newer bikes but the same thing happened on my '03 Road King. If the handlebar controls are to be removed, one is supposed to put a small shim in between the brake lever and the cruise switch to keep the switch depressed. If this is not done, the switch can get broken quite easily.

Good luck getting this fixed under warranty, especially if you've swapped the handlebars. It is not a warranty issue... it is failing to follow the correct procedure during the handlebar swap. If you paid someone to swap your handlebars, you should get them to fix it because they should know better.

[Cvostu]

if it is the brake light switch, it is held in place with a small brass insert that should be held inplace with a small amout of sillicone. That would make the cruise act up for sure. Easy fix if you can find that insert.

I know this procedure but the mechanic perhaps didn`t i guess , hmm , but then the brake light would not lights up again after the handlebar-change , but at mine the brake light allways lights up so i guess that the brake switch wasn`t damaged but had an issue . We will see , no big business , just a switch , how many could this cost , the switch and the work , Important is that i found the reason and that it is not a wiring problem , puh , would be a big job to check all wiring extensions inside the new ape .Better this way .

That is a good indication that the switch is broken. I've seen the same thing on a couple of bikes... brake light on all the time, cruise not working... it was always the switch and always after a handlebar swap.

Good info , thank you .

[evilapes]

I tried the code thing & all my letters showed none. But, after none appeared pn followed by numbers appeared. What is this? Is this normal? Should I worry?

[04se103]

Its normal

Same at mine PN........ seems to be the tach-number perhaps

[Hotrod50]

Just had this same problem on a trip this past week.  It was the front brake switch.

[coolmac]

I had my cruise working intermittently.
I would also get a check engine light intermittently.
HD changed the cruise switch assembly on the handle bars.
All is well for 5K miles now.
My brake light did work normal.

[solitary]

Had the same problem.......

Would be out cruising', stop for some reason (turn, red light) get moving again and hit the restart on the cruise control.

Problem was I had the cruise set for 80 and I was in second or third gear.  When the engine rpm's neared the rev limiter it cancelled the cruise control.  Just happend to be looking at the tach when it dropped out.  Up-shifted to a higher gear problem hasn't reoccurred.

If you had someone mess with your wiring (ape Hangers ?) that might be the place to start looking.

[ultrafxr]

That is the part number of the ecm in your bike.  Normal for this to appear after you have checked all the DTCs.

I've had my 2001 SERG for about a month now. All is great but just noticed that the Cruise Control does not work.
The Cruise power light switch works but the "C" in the tac does not light up at all.
The brake light works fine.
Any ideas what I should check?
Thanks

Just because the brake light works isn't an absolute.  Make sure someone hasn't put an LED bulb in it at sometime.  If so the bike can think those are a bad bulb.  Not likely perhaps.  But worth checking since it's a free and easy check.  Aside from that there's not a lot to cause absolutely no function. 

Master switch on the nacelle, engagement switch on the right grip, a busted or frozen stepper cable or a bad module (assuming there's no harness problem.  There's just not that many pieces to those system.  The switches you can test with a multimeter or a test light.  The cable you can test by feel (once you've got the end of it accessible).  If everything else is good you've narrowed it down to the cruise module.

There is a roll-off switch in the idle cable.  It serves to disengage the cruise under forced throttle though.  You can completely unhook it and the cruise will still work.

[Denial]

Go figure, it works now. I went for a long ride today and kept engaging the "set" switch on the right handle bar. All of a sudden the green "C" light came on for a second or two. after about a dozen times it came on and cruise worked fine.
I'm guessing it was the switch. The previous owner never or rarely used the cruiser in the past couple years.

In that case....

As part of my spring maintenance every year (ok, maybe every other year sometimes) I hit the handlebar switches with a squirt of electrical contact cleaner then blow them out well.  Sounds like a dirty switch.  It happens.  Gotta love simple solutions.

[Denial]

Thanks, I'll give that a try.

[rganz]

Sounds like my issue too. I started a thread a few days ago because I noticed my brake light stayed on , but I did not notice I had no cruise control at that time.  I checked and sure enough no cruise and brake light stays on.  Can't get mine into the dealership until the middle of May due to work commitments though. Good thread gents and great info from all .

Mine did this a while back.... I was also having intermittent ABS issues... dealer found one of the wires for the front ABS sensor severed in the insulation... causing an intermitent issue...

fixed wire OK now...

Got the same problem with the same bike, did you solved it?
