Trans fail safe

Have this message at start up but clears if I restart. Battery good and I’ve stripped xyz switch and all looked good. Box changes fine. Anything in the box that fails to cause this?

A faulty transfer box shift motor potentiometer is a possible cause (although, usually, it's the battery). Does the transfer box shift into low range and then back into high range okay?

When you say "the batteries good" how have you checked sir?

Phil & Craig are right about the battery.

I'd take it a bit further and advise you to change it if older than 2 years, regardless, before looking into anything else.

Those times you get the message, upon turning the key, do you have selector position indication displayed on the dash (P or N) ?

I had the same issue and was so convinced it was the xyz switch that I purchased another one, luckily at a bargain. My battery appeared to be holding its charge until it didn't...New battery and all was magically cured Thumbs Up

Battery is new and I’ve charged it to make sure. Not sure about lights on dash. Wonder what happens to potentiometer.....

I wonder what goes on the potentiometer to only effect it when cold? Put the inhibitor back on and still the same. No display on dash.
