Bike: '23 FLHP. This is NOT how to steal any bike I walk up to.

Have been living with the security system for over a year, have read the book, can do the PIN and still find the system annoying even though I keep the FOB in the saddlebag and the system is practically "invisible". It is personal preference, not open for discussion. I am contemplating taking the bike in and having it put in the Maintenance Mode so I never have to deal with the FOB/security system again, yet can easily reverse that if a family member or second owner wants the security to work again.

The "Money Question": Is there a "Side Benefit" (for me) that a partial or total failure of the security system will NOT lock me out of using my own bike while it is in the Maintenance Mode? That would be the icing on the cake as far as my personal preference goes. I understand that if the antenna lead breaks or the system fails, I can no longer reactivate the system by brining the active, assigned FOB back in range, and that is fine as long as I am the owner. Will let the next owner work that out if he wants to.

I ask here first because often the techs who can repair a system don't necessarily know how the system is designed or the fine points of its operation.

 

There’s always a chance of a partial or total failure of the security system whether it’s in normal mode or service mode. How much of a chance? There really is no sure way of knowing when an electronic device might fail.

 

I switched the BCM out in my '16 RGU, and forgot to put a pin # in when I was setting the new BCM up (so no pin number at all)... I didn't even think about it until a day later when I was in the garage, without my FOB, and started the bike up and then realized I didn't have a fob on me. I left it like that for a few days until I got around to putting a Pin in, then it was back to "normal".

Your dealer should be able to turn off the auto arming without issue, if that is what you want.

 

What happens if you set the code to all zeros. Know the Exported Harleys as far back as 2004 could not be set to not auto set.

Now that is the ones without a BCM and everything was interlinked with TPPS, speedometer and ECM.

The TPPS is also the bankangle kill system. If that fails, bike will not start.

And there have been 4 cases in the last few months of this. And there is no replacement parts to be had. You can jump the TPS non alarm bike.

You loose signals, and bank angle switch but least the bike is not totaly junk.

The mother ship wants to sale new. After a certain point, first poster's thought is a real concern. Especially if you keep stuff a long time and live were it's safe to park a Harley.

Seen a few BCM failures here lately. Is that what happened to yours?

Harley saved a lot of money eliminating parts with the BCM and throttle by electric wire. Just how vernable they are is still up in the air.

 

I believe maintenanced mode is turned off next time you turn on the switch with a FOB near by.

I’m splitting hairs, but technically, it’s called service mode. The dealer has to set it with the DTII and, yes, service mode is canceled when a fob is within range.

FWIW, the security system can be turned off with the TechnoResearch SuperPro. Most dealers and indy's have one. Or if you want, ride to Vegas and I'll do it for you.

 

Best I can tell a immobilizer system is now require on any motorcycle over 125cc.

It's interesting that for older Harleys, Harley still makes the European TPPS. I had assumed it would work on a US bike.

However, a USER said when he ask, his US dealership didn't have the European software to do it.

The standards for part available is determined by the country. Go figure .

 

Thank you, one and all. The correct term is important (service mode) to avoid confusion and not sound like an idiot in the service department, thank you. Also did not know the security system could be disabled, shut off with certain "tuners". Zeros are not an option in the PIN, only digits 1 through 9. Still don't know if, while in the service mode or disabled, a security system failure will or will not disable the scooter. If I can find one, this gives me a few more things to discus with a knowledgeable technician.

The few times my fob is out of range and I am surprised by the need to enter the PIN, I am slow to get started and run out of time. That 2 minute wait for the second try chaps my posterior. Thanks again for the help.

 

Op, a dealer can get to those same settings with Digital Tech.. and I don't think its that big of a deal to shut it off, if you are ok with it and it's what you want (turn the ignition switch on and go). BCMs going bad can happen no matter what your settings are, but it is an infrequent occurrence, and how you set this isn't going to influence the reliability of the BCM. If you are up in the NE part of the state (Tulsa area), I'd recommend the dealer on Brookside... my experience is that they are more user friendly when seeking out of the box ideas.

Jack, no my BCM didn't go bad... I wanted to add TPMS to my 2016 RGU, so I needed to change the BCMs to the #41000341x BCM to do so (stock BCMs on non-CVO's touring bikes prior to 2017 were not capable).
