I have been searching the web for a place to buy the adapter that will go from the port under our seat to the ODB2 scanner to clear fault codes and the engine light rather than going to a dealer every time to do it. I can't find anything. I have a bluetooth ODB2 scanner already that connects to my android phone but still need the chord to connect to the bike. Can anyone please help me find that chord I am in dire need of it. I apologize in advance if this has been brought up many times on this forum.

These are the 2 connectors with some reference pins. The real pinout is here.
You connect
Pin 4 - Gnd - Pin D
Pin 16 - +12v - Pin C
I recommend you twist them as a pair
Pin 6 - CAN +ve - Pin B
Pin 14 - CAN -ve - Pin A
These you must twist as a pair.

Hello ausrobbo... Can you share the part numbers for the bike side connector and the pins that slide into it? Or what the brand and model is? There are many different types of automotive connectors; I want to make sure I get the right thing.![Image]()

For those who are wondering, I found the part number. It is Sumitomo 6188-0004 or 6180-4771 (not sure which is male or female). I ordered mine based on the picture from this website: Motorcycle MT .090 Sealed Series - Connector and Terminals
I got the "Male Half Only", listed as Male MT090-47. The heading on the website is "4 pin MT .090 - 2.3mm Male and Female locking connector." I hope this helps someone.

I have a 2014 FZ-09. No fault codes, but I decided to make an adapter following the info above just in case I need it in the future. Wired everything up, triple checked everything is correct. Purchased a Bluetooth dongle that works with my iphone and downloaded a few different apps. I got one app to connect to the dongle, but it won't communicate with the bike. I set it to ISO15765-4 CAN 11bit 500kbaud per a different thread here. I tried my wired OBD2 scanner and it doesn't work either. Finally, I purchased a wi-fi dongle that is also iphone compatible and downloaded their suggested app. I can connect to the dongle, but the bike doesn't communicate with it. Am I doing something wrong?

Hey, did you twist the wires as shown?

I found this, also from a UK seller, but it's a cable, not a plug.

There are a decent number stateside. Flash Tune, Woolich, Dynojet, and others all make a cable.

I twisted the wires and double checked all my connections. Still no communicating with bike. Any other clues?

In for more info on this as well. I bought the 4 pin cable a while back with my BT dongle and tq app. I know the dongle and app/phone work as I've used it on my car a number of times. Had no luck getting it to sync up with the bike.

I'm sorry; I can't really help any further other than pointing out the obvious :/.

I was successful erasing a code with these two items. Have to move the pins in the OBD2 connector to match the locations show above. I removed some insulation from the wires and wrapped the wire around a short piece of a paper clip then secured it with some heat shrink tubing. I'm not sure why twisting pairs is recommended or required but I did it anyway. Then just pressed the paper clips into the female connector on the bike.
At first the scan tool came on but did not connect and read. I unplugged it, then turned the ignition key to ON then plugged the scan tool back in. Pressing enter per the instructions still did not make it scan but then I held the enter and the scroll buttons at the same time and it read then allowed me to erase the code. Worked great.

I'm pretty sure FT (flash tune) sells these things for like $40. I got one for my ZX10R when the tip sensor re-installation threw a common code... otherwise the dealer is gonna charge you like $100+. $100 just to look and another $40 for "wear and tear" on the OBDII scanner lmao.

I made my own yamaha 4-pin to OBDII harness, and it worked perfect! I cleared the check engine light on my 2017 FJ 09 with ease.

What's the theory behind the twisting? So far as I can tell, it's not necessary. Having said that, I used paired wires that are side-by-side. Is it something to do with current induction?

I have a 2017 FZ09. After changing the spark plugs, I forgot to connect the fuel pump wiring harness and turned the ignition on so I got a check engine light. I removed the tank, connected the fuel pump wiring harness but the check engine light wouldn't go away.
I used these to view and clear the codes and it worked flawlessly:
