Greetings fellow Alfisti! The other morning after cold start, I flipped the DNA to "A" as there was fog and the roads were wet. It did not change modes, so I attempted "D." The LED remained in the center and was white. The next time I drove it a message appeared on the display informing me of a DNA failure followed by a CEL that has remained each time I've started it since. I have not attempted to change mode again. I did not finds any threads in the forum about a similar problem. I hope it is a weak battery, corroded terminals, or an electrical connection as often occurs with the transmission switches. DIY troubleshooting starts Friday. If it is none of the above, it would have to be a wheel sensor or ECU issue, correct?

It shifts fine manually and otherwise no other issuesl. I've had it for a month, so I do not know the age of the battery or trickle charger status. I will check codes, battery terminals and more on Friday and report back.

19,889 miles. I believe the ECU is factory (I’ve had the car a month). Previous owner offered no details.
