When plugged in, this factory Husqvarna ABS dongle enables additional features in the ABS control unit that can make life with the 701 so much better. See below.
ABS mode 1 is automatically activated when the dongle is inserted
THIS DONGLE DOES NOT SAVE ABS SELECTION ON 701 ENDURO and SUPERMOTO MOTORCYCLES
After the ignition is switched off and back on, the bike will automatically revert to ABS mode 1 "Supermoto" if the dongle is connected

Installed this on my 2018 701 supermoto. I like having the rear ABS off and not having to hold the button down every time I start the bike. - 1 star because the light blinks yellow every once in awhile. I may be weird but it bugs the heck out of me. Overall great product.
