The four wheel drive light started flashing 4 times, and now the four wheel drives doesn’t work. Does anybody know what this means?

You've lost voltage. First thing, you'll need a good working battery in the bike. Check the fuses, check the ground cables and battery cables connections. There is a frame ground and a motor ground... take them loose and clean the metals up & retighten them. See the attached image. Better yet, get a free copy of the FSM and read it. Have fun!

Welcome to the forum Trevor , I have a 2002 450 with the electric selectable front diff like you , I really don't know about the flashing lights as I have never seen them go off before , I had a problem with the connection at the front diff coil , wasn't getting flashing lights but would loose the front diff and blow a fuse , I cleaned out the plug ends with WD40 and compressed air , then packed them with dielectric grease and it been ok for a long time now


from what I know about the system , a speed sensors doesn't engage the front diff while going to fast and cause damage , a coil on the front diff that engages a collar on the splined pinion shaft

check your speed sensors at the front differential.
