2001 Traxter won’t go into Diagnostic mode

Anyone come across this?

Bike starts up and drives but won’t auto shift. It will shift manually.

I’ve searched all over and found nothing. Bike is in Neutral and first gear, put in the jumper (brand new from the parts store) underneath the LF connector and the bike in the off position. I turn the bike to on and no diagnostic mode.

Bike starts up and runs, if I push the start button.

Am I missing something? Any help would be great. Thanks
