Venting: It’s important for my use the transfer case Neutral position functions, because I bought this truck to tow behind our motorhome.
I tested it before I bought it in December.
I have operated it a few times since.
Today I hook it to the tow bar for a test run and when I put the selector to N I get “Service four wheel drive system”.
Leave it sit for five minutes and the message disappears. Everything works; 2H, Auto, 4H, 4L. Except when I try neutral again and the error message pops up. Rinse and repeat several times, same thing every time.
So, back in the garage. I’ll check the connectors in case the dealer left something loose when they replaced the transmission recently. No, the connectors look good, they even put dielectric grease in them. So, I cleaned out the plugs and sockets with contact cleaner, just in case there’s some grit or foreign material held by the grease that may inhibit a good contact. Aaaaand success! In and out of every position including neutral, just like clockwork. Repeatedly.
Back to the tow bar I go. Hook up the bars and all the umbilicals. Shift into neutral. “Service four wheel drive system”.
