95 GC "service 4wd switch"

i am hoping someone can help me. My wife's GC keeps notifing us to service
the 4wd switch. What exactly is it telling us?

Thanks in advance

For some reason the cluster can not tell what position your transfer case is in.
It's not a critical thing if your transfer case is shifting properly.
(i.e. you haven't been in a wreck or bounced off something
that could have smacked the transfer case) Like a big rock

Shift it through the settings and back to see if that fixes the problem
then get under and disconnect/reconnect the plug at the sensor on the transfer
case. Should be a oval four conductor up on the transfer case.
