very good point Jim.

With a test light, I found which wire energized with the button. I cut that wire and sent it to the Stebel relay-either #85 or 86-other one to ground, can't remember which. #87 to + on Stebel, - on Stebel to ground.

There is only 1 wire connected to OEm horn.

This is why I wonder if it was just some sort of temporary glitch

there are 2 wires that went into 1 connector. you would have had to cut 1 of the 2 and then do a continuity test to see if you cut the proper on. 50/50 shot. if you cut the wrong one then you have to cut the other side and repair the connector to the first one.

then that wire goes to #86 of the relay, power from the battery goes to #30, ground is #85 and the output #87 goes to the horn.

Hey Guys,

I have a 2009 MP3 500 IE. When I leave the bike parked, I usually turn the bars and lock the forks. Suspension is locked, kickstand down and parking brake engaged.

The bike will be left like this for up to 2 weeks at a time as I do not get to ride it often.

I the bike is left like this for more than an hour or so, the horn will start beeping whenever I insert the key and turn to the on position. The only way I can get it to stop is to start the bike and twist the throttle. It's rather embarassing and I cannot seem to figure out why.

Any ideas?
Go Look at this Video and see if this helps you...

My interpretation of your text is you have a DOT4 Pressure issue with your Tilt-Lock... But if you have a Beep... Beep... Beep... issue, its your Battery.

With my test light poked thru the insulation of a wire chosen at random, I pressed the horn button and it lit up. This is the one I sent to the relay. Didn't bother to check the other one-figured I'd guessed right. I'll check the other wire this weekend, but I don't see how I could have screwed up, but then again, who knows

OK, got to thinking about it-IF? I had cut the wrong wire and sent it to the Stebel relay, then the Stebel wouldn't honk when I pressed the horn button-right? Only when the bike was tilting to extreme.

I think I'm vindicated! ?

FWIW, bike is till upright after 5 days.
I call a glitch!

Low fluid alarm
Okay tried all - then removed the windshield assembly to check and sure enough my fluid was low or empty!! I have 25k miles and honestly don't know if the was ever serviced by the dealer I have been taking it to...especially with all the dust etc. anyway filled the reservoir replaced the cap started and drove a couple of miles but the horn still honks 5 times every time I engage the tilt lock!! If it ran dry is there a process to bleed this system? I don't see any leaks or signs of oozing etc but I will keep watching since it is now full of fluid!

Any suggestions would be great!!

Since it's raining buckets, I decided to restrip the tupperware off the front to get a look at the tilt lock reservoir- it only had about 1/8" of brake fluid in it-well below the minimum line. On top of that the rubber seal with its keeper had been installed with the rubber seal pinched down inside of the reservoir. No damn wonder it was losing pressure over a weeks time. It was a little tougher to get there as I have a windshield with its attendant brackets to remove to get to it.

BTW, the nose piece with the center light-it says to remove 1 screw and lift it out. I removed the screw, but it didn't want to "lift out" and I didn't see any other attachment. I didn't want to break any tabs so didn't force it.

How does it attach/detach?

On the way out, I found a few speed nuts installed backwards, so corrected that. Guess it's hard for some people to be smarter than a nut, huh?

Hopefully, my tilt lock bleed down is corrected.

I got the same Problem
The bike starts fine but will not disengage the Tilt Lock. Double tapping the tilt lock lever also will not disengage the Lock. If i try to accelerate or double tap the Tilt lock I get a continuously beeeeeeeeeep (not horn honking). Since it wont unlock, it will not go.

First, I trickle charged my battery to full. But this changed nothing.

So, I pulled the front plastic off the bike to check the Tilt Lock fluid level. It was totally dry. I filled it. But the problem persist. Also the tilt lock seems mushy. Like i can push the bike over right or left while locked. I don't remember it being like this before.

Maybe it needs to be bled. I might try that or take it to a dealer. I will update this as i go.

If anyone is interested here is an Exciting video of how to get to your Tilt Lock Oil Container. https://www.youtube.com/edit?video_referrer=watch&video_id=N3tpZ4N-UXw

Yup, it probably has air in it. But since your tank was empty you also have a leak somewhere. You could try to bleed it, and if it works at least you know it isn't a pressure sensor failure or something like that. In all likelihood it's just due to the pressure sensor working properly, and you have no pressure. But, you do have a leak.

If it was me, I'd probably bleed the system and see what happens from there.

I wonder if brake fluid contains luminophore (a substance that emits light when ultraviolet light is applied). If so, finding the leak is much easier.

I have seen A/C refrigerant with UV dye, but never brake fluid.

Some coolants contain that thing too. They have "acid green" color.

i've read the post for the third time and he's n't talking about a lock unlock fault so the beeping sound can also be from the speaker then its a low voltage alarm

when you hear the horn 9 out of 10 times you need to unlock manualy or can't lock the front

when you hear a beeping sound and have to give full throttle to start it's 6 out of 10 times a low voltage battery

it has a electronic fuel injection the ecu needs also power to read the mapping, when you give full throttle you override the mapping a littlebit, but it still needs power to respond

that's why modern electronic fuel injected scooters don't have a kickstarter iff the battery is to low it wont start even with a kickstarter the startermotor will draw all the power then there isn't enough for the ECU
The Beep... Beep... Beep... Etc... Definitely a battery.
I just had a Earth-X ETX-36C go bad on me.
Switched to the Motobatt.
I have had to many bad experiences with the Lithium-Iron can going back to cheaper and more valued alternative.

Hi, let me introduce. My name is Ruben, I'm from Russia, I've been riding motorcycles since 1984.
I apologize for posting in the old thread, but apparently a lot of people are facing this problem.

2. Push the "CLOCK" button for less than 1 second and the icons are displayed sequentially. he icon selected remains ON and the other is no longer displayed.

3. Press the "CLOCK" button again for more than 3 seconds to reset the relative maintenance step and the icon is no longer displayed.
I have Gilera Fuoco 2009 (like MP3 500 for USA) and the same problem. Qouted above did not help me and I still hear the horn 5 times.

I bought a used scooter recently and the horn did not work. Today I visited a electrician who saw that the positive wires was removed from horn. When he was put the wires on the contact, the problem with 5 horn signals was begun.

Why a electrician, but not dealer: there is only one Gilera scooter service station in my country, 900 miles (≈1500 km) from me. The situation is about the same with other brands, so we use narrow specialists (like doctors): one knows motors and variators, second knows about electricity, third plastic and bodywork, fourth paint after an road accident, etc.

2 weeks ago, another technician (mechanic) changed the hydraulic fluid, extracted an air (correctly, from bottom to top) and the tilt lock keeps the scooter rigid. I am confident that the hydraulic system is sealed and there are no leaks.

I guess I have no hope to replacing the pressure sensor and therefore I'm planning to take Buzz1956's advice and cut the red / yellow wire near the horn of the device.

Horn Alarm goes off every time I turn it on. Solution.
Today I read the wiring diagram of the scooter and found a simpler solution than Buzz1956.
No need to cut the wire and remove the bottom plastic to see the horn. Remove the top shield and you will see 4 relays. One of these relays will be "Horn remote control switch".

Gilera Fuoco, which is sold in the European market, will have it second from the left. Remove it.

This relay makes the scooter horn sound if your scooter's hydraulic system is low pressure or the pressure sensor is dead. It doesn't do anything else, and this is a relatively easy way to remove the annoying signal.

Unfortunately, I do not have a circuit diagram for Piaggio MP3 and you will have to find this relay yourself.

Thanks to my avia friend Buzz1956 for your research!
