Red neutral light coming on

[H2005]

For a few days now my red neutral light has been coming on when I start my H2. Yesterday it did it again except this time when I hit the 4wd open button it flashed and completely locked me out of everything except 4wd open.

Then after that the dreaded service 4wd came on my DIC. So I turned it off and restarted it and everything is fine now. Anyone else ever experience this?

Help to have it scanned for codes in the tccm, b2725 i suspect it may be setting which would indicate a mode switch malfunction
