On the EFi 250 GV , any OBD plugs will be near the fuses , otherwise some models do not come with it , especially here in UK , i’ve had models that only had a 2pin plug to trick the ECU to output code on the dashboard Display – I have noticed older models don’t make it easy to try to hook up to a software on phone or PC to read anything unless you have a “official hyosung scan tool” which is only reserved for authorized dealers , they don’t normally sell them to the public.

Thank you bro but i saw on youtube ms 309, ms 309 pro obd2 we can scan Hyosung gv 250 ecu. And just elmm327 again i saw it perfectly scan with gv 250. But i dont know gv 250 s ecu 4 pin socket diagram. If i would, i would connectöto elm 327 with manually. Do someone know 4 pins diagram for elm 327?

Nice to meet you from Japan. I’m also struggling with the same issue. And, as Marcel says, failure continues. It’s a difficult task.
I’d like to see that YouTube video. Could you please introduce the URL here?I will tell you my results.
Regarding the 4p coupler, mine is Daewoo ECU. It seems to be the same. The 2015 GV250 probably does not have a 2P coupler. I think the orange line is 12V, the light blue line is the ECU signal line, and the black and white line is the negative line.Then I thought it might be an ISO9141 K-Line or SAE J1850 VPW pattern.
Therefore, I ordered a 4P⇒ODB conversion connector from Ukraine that was written to be exclusively for Hyosung. The conversion was orange ⇒ No. 16, light blue ⇒ No. 7, black & white both connected to No. 4 and No. 5.
Unfortunately, I could not connect it to the ECU.
Similarly, my friend’s 2012 Delphi ECU could not establish a connection to the ECU.lastly.
Some people have had success with past topics on this forum, so I’ll introduce them to you.

Thank you mate. I learned Hyosung ecu is delphi system and thats why with obd2 normal systems intel, impossible 🙂 only delphi obd2 system can diagnose this fckn brand s ecu. And there is no need to 4 pin use k-line, +12v and ground that we use. Other 1 pin is for updating ecu

Did you ask the Youtube person who uploaded the video ? if they did any software hacks/tricks to do it ?
As here in UK , Garages use the official Hyosung Scan tool

Thank you again bro. I reseted ecu. It was soo easy. In a 2 seconds, i made on of key 5 times and ecu reseted. Since 3 days i am geting just o2 sensor 1 high voltage, o2 sensor 2 high voltage. Bike is super. Everything is super but f1 light is lighting but there is no problem on driving. Is this f1 ignore important or never mind? And how can i solve this problem?

It means replace the parts soon because if O2 sensors fail, the bike will stop running = FI/F1 warning is telling you the ECU thinks there is a part that is almost going to the grave soon (not in good spec anymore) or part is loose
Also make sure regulator is always 14v (idle) and (5,000 rpm) – If it is 16v , it will fry a lot of parts and the ECU is very sensetive and expensive part to replace than a carby CDI

Bro hi. I measure voltage. Battery 12.7v when engine off, when bike works 14.3v 14.5v. 🙠but this fckn sensors problem 🙂
Everything is perfect with my bike(starting, driving, sound) just f1 light my problem. Why it is lighting?
By the way, today i measure o2 sensors sockets voltage.
Female ecu side ( -,-,-,- )
outside (-,,-) 2 pin 14.3v,
inside (,-,-,) volt 4.3v -
Yes yes, i checked bro. Between 13.3 and 14v. My bike at 52.000km need new 2 sensors. From aliexpress i gave an order. Hyosungwholesale bastards selling very expensive. Many parts of this bike really cheap in aliexpress. 1/3 less price from hyosungwholesale web site. Those bastards are really very clever. But i found more cheaper

Look for a 2nd hand sensor in your country and replace it ?
or take it to a garage , ask them to clean the 02 sensor for you and try again.
Make sure to reset ECUÂ (unplug battery for 24hrs)

Noooo this way is jurk bro. If you want put battery 1 year like that, nothing happening. I found factory’s way for reseting ecu. In 2 seconds on and off ingation 5 times. Gear N possition, red switch On possition and on of, on off, on off, on off, on off. x5 times in 2 seconds. I did it and Yesssssss. It done. But may be 10 15 20 times ı tired. But at the end it has done.

I bougt 2 new one from aliexpress. Waiting for them.
As long as it is a genuine Hyosung part, then it should be OK, as we tend to avoid chinese parts for a reason.
Good luck!

Which ones were they ? Pictures ?  I mean as long as its not some “knock off” , then you won’t have to worry about being stranded again.

ET sensor has different connector.
I will find more in UK that does not involve cutting customer harness.
I have never bought anything fron Aliexpress in my life. Usually i get most parts from wholesellers where i live😬
