LMM: Service 4wd and Co 396 code?

[Big Chris]

I lost 4wd and I get the code Co 396. Switch lights up when I start the truck. Nothing when I shift to 4 hi or low. Any ideas? I replaced the switch and that didn't help.

This is an all data for a 07 but should be the same

Thanks. Looks like I have some troubleshooting ahead of me.
