Air compressor - anyone tried a Switch? & where is the fuse?

[BertRemington]

Suspension failed on the drive home from the selling dealer who assembled the Spyder incorrectly and is apparently NOT the local dealer performing warranty service.

I picked up a new 2021 RT Limited today. On the way home about 100 miles I got on the dash about 5 times a message Suspension failure. ... The dealer where I purchased the bike is a 100 miles away. https://www.spyderlovers.com/forums...1-RT-Limited&p=1624037&viewfull=1#post1624037

15psi is the comfort pressure

I put 15 pounds of air in the air bag and that took care of my suspension failure and the ride is much better. ... I really like it over my 2019. https://www.spyderlovers.com/forums...1-RT-Limited&p=1624184&viewfull=1#post1624184

And then the suspension broke

Yes the dealer is trying. Especially I didn't purchase the bike from them. https://www.spyderlovers.com/forums...ock-leak-oil&p=1635139&viewfull=1#post1635139

When I got it I put 15 lbs in it and it rode great. ... The compressor just doesn't shut off. https://www.spyderlovers.com/forums...ock-leak-oil&p=1635177&viewfull=1#post1635177

I called the dealer today and they haven't found the compressor problem yet. They replaced the shock but have not found why the compressor keeps pumping up the airbag. They have had it 2 1/2 weeks now. https://www.spyderlovers.com/forums...ock-leak-oil&p=1636091&viewfull=1#post1636091

I called the dealer this morning to see what they found out.They said when the shock bolt dropped out it damaged the sensor to the compressor. https://www.spyderlovers.com/forums...ock-leak-oil&p=1636307&viewfull=1#post1636307

The dealer that is doing the work is not the dealer I purchased the Spyder from. They are doing it under warranty. https://www.spyderlovers.com/forums...ock-leak-oil&p=1636460&viewfull=1#post1636460

They said they replaced the censor that regulates the compressor. Same as before they must not have test rode it. It does the same as before. Ride it a short ways and it will have 90 lbs of air in the air bag. https://www.spyderlovers.com/forums...ock-leak-oil&p=1637422&viewfull=1#post1637422

Mine just pumps up 90 lbs in the air bag. I like to keep the air bag about 20 lbs. ... I would like to just have 20 lbs in the air bag. https://www.spyderlovers.com/forums...-is-the-fuse&p=1637427&viewfull=1#post1637427

==========

Based on this history:

(1) 15-20psi is the comfort pressure

(2) the rear suspension including the leveling system is not fully functional

I've posted this before, and I've posted this in the other thread running atm asking about air bag pressure, but I'll copy it in here just for the helluvit, it might help some to understand what's going on with their ACS & the air bag pressure.... :dontknow:

I dunno why people are worried about the ACS Air Pressure!! :gaah:

On Spyders with ACS, the air bag pressure automatically adjusts to maintain the pre-set Ride Height.... so the fact that you've got 5 psi in the bag or 95 psi in the bag is purely incidental & a direct result of your Spyder's pre-set Ride Height. :lecturef_smilie: . Nothing in the ACS will allow you to adjust that pressure for a given Ride Height & it might even vary significantly to maintain that given ride height in response to any of the variables that can otherwise cause changes in ride height, but you (or your dealer) can use BUDS to get your Spyder's Ride Height re-calibrated if you feel the need to vary that!! :lecturef_smilie:

So unless your Spyder's suspension is bottoming out or topping out all the time, which implies that the pre-set Ride Height is basically OK, then you really should just ignore the specific air bag pressure & just

Ride More, Worry Less - particularly about the air bag pressure,

cos that air bag pressure's probably gonna change either a little or maybe a lottle all the time in response to any variations in things like the load; the temperature; how hard you're braking; how hard you're accelerating; where you &/or your 'load' is placed on the bike, etc, etc, etc!!

The only real reason you might want to be bothered about the air bag pressure is to watch it to see if it fairly rapidly drops to zero, cos that means there's an air bag puncture, a dud relief valve, a dud compressor, or a dodgy height sensor; or to watch it to see if it starts climbing up over 100 psi & stays up there, cos that means you've got a dud height sensor or a dud relief valve! But apart from those extremes, the air bag pressure is purely incidental & can vary anywhere between about 5-10 psi & 90-100 psi AND STILL BE NORMAL!! It's simply trying to maintain your Spyder's pre-set ride height! :thumbup:"

The only thing I don't like is after I go about 6 milesI get a message on the dash, suspension fault. Fault code C21E1. Shut the bike off for a little while the fault code is gone. I go about 6 miles and it is back on and message on the dash off and on.

The only thing I don't like is after I go about 6 milesI get a message on the dash, suspension fault. Fault code C21E1. Shut the bike off for a little while the fault code is gone. I go about 6 miles and it is back on and message on the dash off and on.

As I may have mentioned earlier, I don't have a code list that includes that particular code, but I believe it's reporting a Suspension Air Leak Plausibility Test failure; and if this is the case, it's very likely that it's simply telling you that:

• there's likely an air leak somewhere that is triggering the compressor to add air all the time;
• the height sensor switch has failed & is triggering the compressor to add air all the time;
• the bleed valve is leaking & is triggering the compressor to add air all the time; or
• you keep on lowering the air pressure in the bag so much that it's triggering the compressor to add air all the time and as a result the system thinks there's an air leak problem!!

There could be more, BUDS might even have Test Procedures attached that could narrow it down a bit; but that Code is almost certainly just trying to get you to look at the ACS & check for air leaks & rectify them or whatever's causing the compressor to run all the time! By shutting your Spyder off every time you see that code, the system can't measure any more height loss while it's switched off, so the code clears; then after you start up & ride on, it takes about 6 miles or so before it gathers enough data again to tell it the ride height is too low before it retriggers the same code again!! :lecturef_smilie:

If you don't want to take it to a dealer to get that sorted under warranty, then it's up to you to either fix any air leak or whatever's causing the system to 'think' there's an air leak (because the ride height is too low ) or completely bypass the 'automatic' bits of the ACS & set your air bag's pressure manually, altho that is effectively negating the system's ability to adjust & maintain your Spyder's ride height in response to any changes while you ride....

But as I've said previously, the Air Bag PRESSURE itself is purely incidental & has no real bearing on this - and you continually playing with it & dropping it down to a level well below what the system believes is necessary to maintain the preset ride height may well be at least contributing to the problem!! :dontknow:

However, as other's have mentioned, I too believe that your shock issue has damaged something more than just the shock/shock bolt under there, probably either the sensor itself, the sector arm, or the bracketry that holds it all; and until you get all that damage sorted and the pre-set ride height recalibrated, so that you can leave the ACS alone to do it's thing, OR you bypass the ACS 'auto' bits completely, then you're going to have ongoing problems like this! :lecturef_smilie:

Just Sayin' :cheers:

It's a NEW bike that they &$#@#$ up!!!! Take it back and tell them to fix it, it's really not that hard if they know what they are doing!!! Don't lay down and take it like this, fix it right, or find some one that will help you to make it a manual fill!!! good luck!!

I took it back to the dealer this morning. They looked up the Fault code C21E1 and called BP and was told it is probably an air leak making the compressor to keep pumping. That raises the pressure. I don't really know but told them to keep it till they have it fixed.

Add my 22 RTL with 1600 miles to the list of ACS failures. My wife and I were riding Saturday on a road with a few dips when "suspension failure" message popped up. I stopped, shut it off and it was gone...at least for a few miles down the road. Got back home and checked the sensor linkage, it was connected. It still had air in the bag. I bleed it off and then started, put in gear and released the p brake. Still no compressor. Checked all the fuses, none popped. I removed the rear seat and had a look nothing that I could tell was disconnected but couldn't tell which connector was for the compressor. I used a bicycle tire pump to pump in around 70psi and done the start, in gear ect ect. The air did bleed off to normal suspension height. Took it for a ten minute ride one up and no message. Now after my ramble... Where and which connector is for the compressor? I want to do a preliminary electrical check before taking it to the dealer. Thanks in advance

Were is the fuse located?

There is no separate fuse for the air compressor. I have a 2014 RTS. My air compressor would not stop running until there was about 150psi in the air bag. Just take the cover off the Left side fuse box and remove the "R4 Suspension Relay". The diagram on the cover of the fuse box will show you the correct relay. The air compressor will no longer run but the control switch in the dash will still function as normal. There will be no error codes. I weigh 170lbs. I manually put 40psi into the air bag with a battery powered small air pump through the Schrader valve under the seat on the right side of the spyder. This gave me a much better ride than the auto settings before it stopped working. Hope this will help answer your questions.

Thanks for the reply Nighthawk, but you really do need to check the dates before posting a reply in any thread!! ldpost:

Unless you've been continually posting in any given thread from its inception, then it ALWAYS pays to check AT LEAST the START date of the thread (on the first post) AND the dates on the last few posts in the thread.

In this particular case, those last few posts were made back in July of 2022, so I'd really hope they've got it sorted by now! :thumbup:

That said, thanks for making the effort to tell everyone about the fuses or lack there-off anyway!
