Advice Please! - Diff Lock button blinking!

[Adamcolorado]

Along those same lines, we have activated our diff lock multiple times over the last few weeks, with no problems. Stereo is still acting possessed, but the diff lock error has not come back. Temps have been below freezing almost constantly, with lows dipping into the single digits.

Hi. I’m looking at buying a 570 that subs like the previous owner reports radio buzzing and diff lock error. Are these correlated?

My driveway is very steep.
Sometimes when I park I’ll let it roll back and settle right where the driveway meets the street and in the am when I start it the 4LO and diff will blink. Until I shut car off and restart.

I wonder if the cold or the tilt or the loading of axle triggers a fault when you start it in the morning.
