After long,hard day off road I did the normal shift out of D-lock low and back to normal high range(diff lock light stayed on) so I backed up a ways and took off figuring it would go out.Drove for a while(light still on) and pulled over(shifted in and out multi times and backed up until my neck hurt) still won't go out.Drives and steers like normal high and shfted right in high.Had to drive it couple hundred miles with it like this.Any more tricks to try getting light out and anything to worry about?(until I get it fixed).
