Hi, Marcel.
Wow
That’s right, it was in “SINNIS.”
Our leader, Marcel!
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.



Long time no see. Marshall.
Let me explain about the GV250DR.GV250DR was scheduled to be released in Japan. However, there was no explanation from Hyosung Motorcycle Japan regarding the cancellation of the sale.
In the end, it wasn’t released.
(I was sad)The obvious ones are China and South Korea.
My guess is because Honda’s Rebel 250 (CMX300) was released around the same time.
Although it is in Korean, you can officially download the parts list.
GV125S.GV300S is also available.It is difficult to find the service manual because the Chinese site is a black box.
This is the KR Motors website.
Please take a look if you like.
I would also be happy if it was helpful.http://www.krmotors.com/board/board.php?bo_table=parts&page=1

Hyorider from Japan.
2011 DAEWOO ECU GV250Recently, I was unable to start the engine due to an ETS sensor failure.
With the DAEWOO ECU, the ETS sensor error is C15
The new item was out of print in Japan, so I attached the used item.

↑ This is my exchange article. Please take a look. If you can see it, please translate it into Japanese.There are 3 types of FI manuals, so it took me a while to understand.
①SENTEC ECU
②DAEWOO ECU (Complementary to SENTEC ECU)
③ DELPHI EUC “manual name Dspec”probably not very well known
Write the link of the second manual

Want a GV250DRA?
If so, I’m going to ride from Japan to the UK.The price of the vehicle is … 638,000 Japanese Yen…
Including expenses…700,000 Japanese Yen
Converted to approximately £4,000! !Haha! it was a joke
In Japan, the GV250DR and GD250R were scheduled to be released, but they were never released.
GT125R is also very valuable.yeah, that’s good news
I opened the Hyosung Owners Club in Japan last year.
We still have about 30 members, but I hope someday the number will increase like this club.By the way, can I ask Marshall a question?
Do you know the existence of the GV125S/GV300S service manual?
I got some old Hyosung model manuals. But I can’t find the manual for S.I look forward to your reply.

Dear Marcel: Long time no see. Sorry for my late reply.
After that, I became friends with him (ACE-K) on Japanese SNS.
He said he was happy with the parts he purchased from HyoRiders.I will upload it to the photo sharing form.
