Hi,

That ECU part number requires the 6-Pin Type 11 Bike Side Harness. That ECU is also not natively readable. Please use th ecorrect harness to avoid any damage to your ECU

Sorry，i gave wrong information. I use the 6-Pin Bike Side Harness Type 11.

The ECU Part Number 2DR-8591A-20(JP) can't supply for ftecu now ?

If i provide this part number ECU, the software soon can supply for this ?

Hi,

We have a file for that ECU part number. It is under MT09>2014-2020 folder.

If you are still getting the no response message please make sure your Bike Side Harness is installed correctly and perform the 6-Pin Harness Test located on the front page of the forum. Also when flashing using a bike side harness you do not have to unplug anything during the process. Just use key on/off when prompted.

HI,

Bike Side Harness is installed correctly, and perform test return message 36( Tested is ok )。

I can't start my bike when Bike Side Harness installed, bike instrument panel show error code（err h1）.

I can start my bike when disconnect the harness 34pin (Black wire ) 。

Hi,

The Bike Side harness test is a more concrete test than the interface test.

Sounds like you may have a short when you plug in the black wire. Please send me images of your connectors and bike side harness installation to review. From behind and front of the connectors as well as the black wires connections please. You can send them to me directly.
