Glad to hear your bike is back. Hope it remains stable from here out.

Update:
Received the bike back fixed.  Service Dept. stated it was my induction module that took a crap this time.  Hmmmmm....  Anyways, picked my SERK up last night and rode it home in the rain.  No issues so far.  Bike is running strong.  Time will tell.  Naturally, I have all the service history logged, with supporting documents just in case.  Stay tuned for my next episode... :nixweiss:

Maybe ignition module rather than induction module.  Doubt they really replaced your induction module since, well; the bike doesn't have one.

Throttle-by-wire does not scare me much ... it is well proven.

The MoCo's implementation of this technology has me a bit concerned.
There simply CANNOT be a "field test" with this stuff; it has to be bullet-proof from day one.

It's a technology I love to hate if you know what I mean.

Really?  I thought the induction module kit was all the components behind my air filter?  The service dept. printout said it is an Induction Module part# 27685-08A $485.95, that they replaced....  along with a Filter Element gasket p#29645-08 $3.95, and Intake Manifold Seal P#26995-86B $7.90.   So what gives???  :nixweiss:   Are they trying to pull the wool over my eyes?

Induction module is another term for throttle body.  I was under the impression that the throttle actuator was a separately replaceable part that attaches to the throttle body, and that would be what I would expect them to replace, not the complete throttle body.  Maybe not.

I assume on the previous attempts at repairs they replaced the grip sensor.  Now that they've replaced the entire system except for the ECM, what is their plan if it fails again?  I assume a complete diagnostic including tracing all the wiring to see if there might be an intermittent open or short is out of the question, at least until you find a real tech and not a part changer.

Good luck, and I hope your ETC problems are behind you.  If they aren't, and it happens again, I definitely suggest having an attorney contact the MoCo for you to facilitate a buy-back of an obviously unsafe vehicle.  These bikes aren't worth risking your life for.  As someone else on the site says quite often, this stuff isn't rocket science.  However, somehow between the MoCo and the dealerships they seem to be able to make it all seem that way.

No they're not trying to pull something on you.  That was a case of something that seemed funny in my head not translating to text on a bare screen.  Just a jab at the Harley's inconsitency in parts naming sometimes.  My bad.  Sorry for the confusion.

Guess what.....  The issue with my Throttle by wire has returned!!!!!!!!!!!!   Throttle cuts out mid ride, and most of the time won't work on startup during idle.  Bike will be enroute to DIFFERENT dealership to find cause.  About to take the gun to this CVO and put it out of it's misery....

Yes, I read your post and started wondering if there was any relation?  I am furious right now because I was nearly stranded yesterday with throttle issues.  We need to find a fix to this nonsense!

I just read an article on line about someone finding the cause of some throttle by wire issues.  It stated the wiring harness under the seat was being crushed by the riders weight and causing the harness wires to break/disconnect under the shrink wrap at the zip tie where it plugs in.  Anyone ever heard of this?  The article spoke about maybe carving out an indentation under the seat to make a pocket, or get an aftermarket seat with more space....

That's another one I'll have checked.

I had that happen with the audio harness to my headset on one bike. Very plausible.

Another GOOD reason for the MOCO to put a decent seat pan on their seats!!! :soapbox:

I had the same problem with new '08 ultra. Start the bike up and all it would do was idle regardless of throttle input. In order to clear it, I had to cycle the bike on/off a few times. Check engine light would stay on afterward.  After 4 trips back to dealer and a threat to get a lawyer involved, dealer bought the bike back for what I paid in an exchange for an '09 ultra. I had to pay some extra $$$ on the trade because the '09 had a special paint job.  Overall, this was a very frustrating experience that definitely didn't build any confidence in H-D nor the dealers service department. So far the '09 hasn't been plagued with that problem, but it has been troubled with a transmission leak because they didn't tighten the side cover bolts on the transmission not to mention the tank recall.

I hate to say this but Toyota uses throttle by wire. Hope this isn't going to be an issue for us too.
