Goldoxide i am very interested in your findings with the obd2 interface, i noticed different wire colors in the Honda dlc connector for the 2017 model but the same number of connections ( 4 ) in the red connector.
Just wondering what the difference in the manufacturing dates might be, are you able to see what the connection to the 2017 ecu is, the old version uses pin A30 "k-line" for data transfer via the orange/white wire.
And if anything has changed significantly did all Honda service departments upgrade their service devices?
Don't want to be difficult but just curious what has taken place and thanks very much for the picture and info you provided to us, cheers.
Hey max:
I wish I could help you more, but I did have a 2014 CB1100, but acquired the Honda-to-OBD2 adapter after I let go the bike. I use the Honda-to-OBD2 on a Honda Africa Twin, which I suspect also works on many mid-size Hondas 2017 and later. Since I did not own a 2017 CB1100 (or later), I cannot remark for certain. But the seller seems to suggest it works:

Of the four pins, only three are actually used. This is a serial port (I think CAN-based), so the pins are battery, ground, and signal.
My HealTech OBD diagnostic tool saga continues: I received correct Honda H01 model yesterday. Connected everything and started the tool. Got error message ""This ECM is not supported at this time, but we will resolve it as soon as possible Please send the ECM ID shown on the screen along with the bike model/year in an email to support@healtech-electronics.com". Maybe its time to move on to something else
Well that is strange. It should work just fine on a 2014. Why don’t you call Healtech and see what they say.
Did you go on-line and get the most current software version?
Bill , did I not tell you to have a refrigerator full of beer close by in your workshop to drink away your frustrations !
Bill this may help to understand how the " handshaking " works with the k-line pin on the obd connector;
https://www.obdclearinghouse.com/Files/v...ileID=1380
In brief; the k-line pin sits at +12volts and is not active ( no signal is present, just 12 volts )
The interface/computer sends a "wake-up message" by pulling the 12 v to ground in one of 3 ways.
When the e.c.u. receives this message it starts to "negotiate" a data speed setting and after that it responds with requested info/blurts out data for the interface.
The interface box translates the 12 volt level into a 5 volt level by-directional so the two can converse and understand with each other's language.
My guess is that this "wakeup message" has changed with new models ( the computer generates this message in the software program ) but the protocol of the k-line data should be the same since it is industry wide , i don't know.
All this will not solve your "not supported" message but may help to understand how things work, thanks for your very interesting updates.
OBD2 interface update.
Inspired by GO's bluetooth device i got myself an identical unit and cable but i could not get it to communicate with both the cb1100 ( 2010 model ) and my 2020 cb1000r.
The unit and cable plugs in and connects fine with the k-line pin and pulses it low as is the usual handshake method ( i checked this with my oscilloscope connected to the k-line ).
The "torque" app then connects with the device after it is registered on my android phone with the 1234 pass code.
The red led inside the blutooth interface lights up on ignition key-on and the green led indicates bluetooth traffic.
The app then checks roughly 10 different protocols ( according to the app ) but then stops and displays;
Connection could not be established.
Tried several times both engine off and running but the results remain the same and not sure if i missed something?
Just posting to inform others here that are tempted to do the same thing i tried and thanks GO for the picture and info , it no doubt works on your AT but not on my two bikes so far.
then no chance for the bikes before 2017?
Bad story.

That is a lunchbox let down - no success even for the 2020 CB1000R? That is a bit surprising. Early CB1100s is understandable. I would dig a bit deeper into the CB1000R - that is a "new generation" bike.
Hmm, the CB1000R isn't listed explicitly as tested by the vendor, however, a blanket statement is made at the end of the list:

Finally got my new HealTech OBD diagnostic tool working. HealTech had to send me a software update, but now I see pretty graphs and moving numbers. Now I have to spend some time figuring out what is all means
