Hi I have a MP3 lt 300 2011 with a Engine management light on ! Where is the code reader plug 😅

If any of you good people can help in any way ! Engine management Light just came on bike running fine , it had been sitting for two months as the fuel pump went ! Also is there a way to clear it without a code reader ! I have one just can’t find where the socket is on my bike or if I need special lead , any help would be amazing

Thanks 😀

Does it stay on all the time - or only when revving above idle? Regardless, the first step is to monitor your battery voltage at idle and then at higher revs - the usual culprit is a regulator that's given up its smoke, and is sending out a voltage that is far too high.

Morning
Ok thanks it stays on all the time, what should the voltage be I think it said 13.5v on idle ?

Thanks for your help

👍🏻

Hi also is ther a code socket you can plug into like on a car ?

Thanks

Yes there's a diagnostic connector - No, it's not like a car ODBII, it's a Piaggio exclusive system. You need a dealer or some serious electronic know-how to access the codes.

Voltages (with a known good fully charged battery): at idle, anywhere above 12.6V, at 3,000 rpm or higher over 13.8V but less than 15V. Higher than 15V means a bad regulator, as does less than 13V at high revs.

Thanks for your help I will check tomorrow! If the voltage is ok what should I look at next , maybe get it on a code machine

Thank

Good day to you, Mr. Robrjh and Mr. jimc: allow me to chime in here as I have the same issue with the yellow engine management light coming on, not at idle but at higher revs. The bike is running fine and I chose to ignore it but it needs correcting nevertheless whatever it is.
The machine has only done 6800km and should not need a regulator transplant surely? But, as I have found out to my chagrin, these things are like petulant little children and the complaints never end.

Hi mines the same runs fine but the light is always on

Phone around and find a dealer who'll put it on the diagnostic unit for a reasonable price. If you get your servicing done at your local dealer then they should do this for free as part of a standard service.

that would be correct IF you have it in for normal service or maintenance, if your just bringing it in for that alone you probably will pay for the diagnostics.

True - I thought that's what I had implied...

Wait, bluetooth OBD2 transceiver works with Piaggio's connector. I bought an Fiat's adapter and installed a program to my Android phone, and it connected and showed some data.

Most Generic OBDII readers only can read standard codes, not manufacture specific candles.

Going by your location, if you can get to two wheels ahead in Croydon they charge £30 to hook it up to the diagnostic machine and they seemed pretty honest when they done it to my yourban.
I’ve been quoted by other piaggio dealers £80 for that pleasure.

Hi everyone

I have an abs fault on my MP3 where is the best place to start

Thanks
Rob

Hi the fault code is U1705 as says
ABS NODE CAN line diagnosis - no node
Help please please 😜

Its guesswork but you could start at the fusebox. Check the ABS fuses and see if removing them changes the diagnostic message. After that its a matter of going through all of the electrical connection that might be related to the ABS system including wheel speed sensors and ABS override switch ( if there is one). A dealer would test ABS components by substitution but that is a luxury you probably don't have.

My mp3 dose not have abs they didn’t put it on till 2016 , there is. No fuse or no abs light ?

My MP3 is 2011 only 11k on clock

ABS fault (no ABS) on a bike with no ABS is puzzling. In my mind that's not actually a fault. Maybe the code is different for that year? Or somebody replaced the ECU with a different one from an ABS bike? Or there's a wire missing/broken/disconnected that tells the ECU that there's no ABS on this model?

What technology did you use to obtain this code? I am pretty damn sure the Piaggio PADS diagnostic software wouldn't come up with that on a 2011 bike that wasn't fitted with ABS...

Not shore it was at a garage but they agreed I don’t have abs so have no idea got it booked in at another garage in Croydon now

I take it you’re taking it to in moto? Someone who has worked on my bike has said good things about them.

No I’m taking it to two wheels ahead hope they can sort it 😢

Hi all I’ve been told my MP3 not well if your not sitting on the seat and Rev the bike would move of ie the cut out sensor dose not work so the bike is not talking to the other ecu can anyone help

Thanks

So it’s to do with the Electronic parking unit.

If it’s a break in the wire loom then that could be a really expensive job unless you can find the fault yourself.

Did they say much more as I’m sure the more information provided, someone could give you a pinpoint response to the problem.
