Monster 821 2015 missing information

Post by ThisMyUsername »

Hi

I tried to check error information on my Monster, but looks like I don't get enought information to request a license. When I connect to bike, the connection works but at one point I have to choose between 2011 and 2012 model year which both are wrong.

I used ELM 327 v1.5 interface (https://www.astools.eu/collections/elm3 ... -cable-usb) with default settings. If I tried with any other settings, I got error message about initiating ELM device.

Debug info below. Thank you in advance!

Guess I need a different ELM then. Recommendations? I saw a mention about v1.4 on some topic when I was trying to find information.

There are no markings on which side is HS and which is MS, but I got some kind of connection working with the switch being towards the cable. And yes, ignition was on.
