P1875 4wd low switch -What could this be the dash swich or another switch?

What is your question?

This code came up when the check engine light came on. I'm guessing something to do with the 4wd. Anyone know what to check? thanks

Most likely this would be a dash switch fault in your 2001 GMC Sierra 1500. If not I would suspect a wiring issue from the switch to the transfer case control module.

Thanks for the help! - I'll do some wire and switch checking then.
