as per your readings made by ohmmeter, standswitch is OK ...

find somewhere piece of copper wire and remove sidestand switch cable connector ... you should see two wires ... blue/green one you should connect with the copper wire to some bolt (not painted and not corroded) on your bikes frame or even if you can reach negative pole on your battery ... the idea is to bypass bad contact due corrosion or broken black wire on your sidestand switch ... you can also measure with ohmmeter resistance between black wire on cable connector and bikes frame or even negative pole of the battery ... do that and send us readings ... it should be 0 or near 0

when you are trying to erase malfunction history by using diag code 62, engine kill switch must be set to RUN position before entering code 62 ... then turn it to STOP and back to RUN ... memory should be erased
