Welcome to the site!
So, what were the conditions for you to see the overtemp warning? What were you doing? The "HI" indication isn't an FI alert, it's an overtemp warning. Not good.
First thing to check is to be sure it's actually the fan that isn't working. You need to put 12vDC directly to the fan to see if it activates. Once you know that the fan is working after you bypass everything else, then you can troubleshoot from there.
I don't know what you mean by a "multi-function" relay, since there isn't one. The fan works from a dedicated relay in the relay box, so I'm not sure what you swapped exactly. If you verify the fan is working, the only other things are the relay, the fuse, the ECU, and the temp sensor. One or more of those are bad.
The overtemp warning requires an immediate shutdown to prevent engine damage. There might be other things going on besides the fan depending on when that came on.
I may not be perfect, but at least I don't ride a Suzuki.
