DTC C140F.... What does it mean?

So while playing with my new Superchips Flashpaq I decided to check the DTC code list. I have no engine lights or anything telling me something may be wrong. So when I saw this I got a little worried. Here's a screenshot of what the flashpaq had to say... Any input is greatly appreciated.

That's the code you get with the N23 recall issue.

It could also be genuine, but most likely it's an erroneous error being caused by a bad N23 flash. Have the dealer do the most recent update to the N23 procedure, make sure they know to follow the instructions to the letter.

Do I have to return to stock with the flashpaq before bringing it to them?

yes if they flash it with the tune in you will lose it. Then you will have pay i think 100 bucks to unlock tuner.

You should be able to clear the code with your flashpaq but if N23 related it will come back. C140F is a transfer case alignment error.

Taking it to the dealer to get it re-flashed with the N23 procedure updated 7/29/14 has worked for most and should be no charge but some have had to also have the transfer case actuator replaced as well.

You have to push a bit to get the actuator covered as they are still trained to say there is no connection but with bad circuit boards in the actuator causing the recall in the first place.....

As per Kman09JGC - you should return to stock before you take it in.
