• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Where is the Height sensor arm located?

Had the Suspension Fault code come up yesterday and I can tell something is wrong. Been reading on here about a height sensor arm maybe coming loose. Do you take the passenger seat off and take an access cover off to check it or is it something that is visible from under?
 
You didn't mention what model your talking about. Have to lay down on floor and look at swingarm. The linkage bolts up to swing arm. That is first place to look at, report back and we go from there for next problem to fix

Sorry. 2020 RTL

On my 2012 RTS the arm in mention ( I hope this is what you have in mind) is located here by the arrow.
No worries, all my panels was off for another job, this can be inspected by just getting down there and look.

If the arm is in place there is a schrader valve located under the seat where you can add air to the air bag. Check the air pressure. If its below 30 you may be bottoming out. if over 75 or so it may feel like it wants to launch you off the seat everytime you it a bump. You don't say what model you have but it could be a blown fuse for the air compressor, bad compressor, leaking tubing or a hole in the air bag if it's not the arm.
 
It’s a 2020 RTL. Thanks for the replies. I think this is it and it looks fine. My next question was going to be how much air should be in the bag but sounds like I’ll pump it up to 30 lbs tomorrow. The compressor is working by the way. I can’t figure out how to add a photo.

If you've got a height sensor that's working as part of the Suspension Height setting, then just as long as there's SOME air in the airbag (it needs about 10psi minimum), you don't need to and really shouldn't worry about 'how much' air/air pressure is in there, just that there's SOME! :lecturef_smilie:

Quite simply, regardless of how much air you put in &/or might want to have in it, the moment you start to ride, the automatic system will adjust whatever pressure is in there to meet & maintain its specified/hard-coded preset ride height!! So if you add more air than it wants/needs to do that, it'll very quickly be bled out! Similarly, if you lower the pressure to something you think works best for you/your riding comfort - I'm sorry, but tough, cos as soon as you start riding, the system will add air to return the bag to a pressure that'll achieve its preset ride height level! :rolleyes:

If you have access to BUDS/BUDS-II, you might be able to go thru the process of changing the preset ride height to something you prefer, but otherwise, you're wasting your time doing anything apart from checking that it's still got some air in it and that it's not leaking down overnight/to nothing while you ride; &/or ensuring that none of those other things Ed mentioned aren't causing you issues! ;)

Just Sayin' :thumbup:

:agree: If in fact your bikes throwing a code, you may want to just take it into the shop and have them put it on the computer and make sure that sensor that you were looking for is in fact working the way it should, and that the systems not leaking down. You will burn your pump up then you'll ether have a big bill to change your pump or be back to us asking how to go to a manual fill!! Good luck!!
 
I will take it in but I’ve had bad experiences and heard so many horror stories about dealers that it scares me. In the meantime- Put some air in last night and took a ride and no suspension fault. It did lose some air overnight but wasn’t flat.
