Does anybody know what OBD connector this is?

[lobbo]

Hi, already asked this in a few other places but had no luck yet. I'm new to this forum though so hi everyone!

I have been trying to diagnose an EML with my Lexmoto Milano (i know...). Having determined that this is meant to be the OBD port under the right side wheel arch, I have no idea what connector it is.

I had bought a 6pin lexmoto OBD adapter anticipating it to be that but once I had actually taken it apart i discovered it didn't fit and that the connector in the bike is the 9 pin as seen here.

Does any body know what this is or perhaps has a link to the correct adapter to use? Or is it not OBD at all?

It's a 2020/21 Lexmoto Milano 125 EFI, the Euro 4 version.

Does the EML flash when you turn on the ignition?

TBH Lexmoto manages to be reeally difficult to find any info on.

I can find the recommended torque amount for literally every bolt on my bike and it has a proper OBD2 socket...

No flashes. It's just a solid light

6-pins out of 9 so could be the connector. That being said Google doesn't seem to know anything like it for OBD connectors. The majority of bikes have somewhere between 3 and 6 pins.

I'd look again. Something with a blanking plug probably. The blanking plug could be attached to the frame and trying to fool you into thinking it connects somewhere useful

Bikes don't have to follow the OBD standards, so it's probably some sort of OBD adjacent thing. Both of my Suzukis have different pinouts on their connectors, and you can get some detail from the 2012 bike, but nothing from the 2017 bike... It's crazy.

Ok I'll take another look for another connector. Thanks

As Nobby says, getting info on chinese stuff is often a total ball ache.
My first thought was "Clean that feckin connector" !!
then "Clean all the others while yer at it!"
Include No 1 the main power connector from the Stator to the RR

Well done supplying pics, always a good start

I did some quick crude fotoshoppy on yer pic
and we now know its uses the Delphi MT05 system which is
pretty much standard for 1-2 cylinder chinese bikes

Get:
Notepad and pencil/pen
Meter for voltages and continuity
can of switch cleaner
old stiff toothbrush or similar for cleaning contacts
take lotsa pics

That 9 way connector only uses 5 pins from what I can see
2 of these will be for 12v and ground so use a meter to find out which ones
then we have 3 to identify
I'll guess these will be K-line hi and K-line low and signal ground
but some further tests will be needed so I'd start by tracing them back to the ECU
then a patch cable can be rigged up to get it talking to your OBD reader
thassal for now

No has let me play with their MT05 system so be aware I'm making guesses here
but had a quick butchers at my notes and have a theory you can get it to talk to an OBD reader using the 12v, Ground and the diag pin on J1-16

I'm reminded that on some Delphis if you turn the ignition on-off 3 times, the display will flash out error codes so its worth a try

With the bike off:
Turn the ignition On-off, On-off, On. in one second intervals and watch the eml light to see if it starts to flash error codes

if this works it will flash 10 times to indicate a zero
(they all start with zero) then follow by 1 flash for one, 2 flashes for 2
and so on etc
for instance
10
1
2
2
will indicate P0122 a TPS signal problem

What OBD reader do you have?

[Nobby the Bastard]

An OBD reader is an OBD reader. A lot of bike have non-standard connectors so need a patch cable between it and the OBD reader.

An OBD reader is useful on something complex, like a modern car. Great when you have 12 ECUs and 150 sensors.

That thing is not complex. An ECU problem is highly unlikely. There are probably less than four sensors on the entire engine, and if any of the other connectors look like that one, they're probably the problem.

Make sure that the electricity has a nice clean path to move around, see if the problem goes away.

Thanks for everyones help.
I'll give all the connectors I can find a good clean and follow the advice of diagnosing from the symptoms and give up with the OBD route.

High/unstable idle, and the smell of running rich so my guess would be IACV and/or Lambda sensor.

Did you do the on off test to see if it worked or not?

You cant buy them in the shops y'know
very rare them secret hidden relays are
very small y'see? eensy weensy tiny little things.
Fit a new O2 sensor and I'll see if I can acquire one for you
