Trouble Codes: C1803-01 and U1266-02

I finally had time to sit down and run a full diagnostics on my 2018 Armada. I use OBD Fusion and purchased the Nissan Enhanced Diagnostics. It returned the following two codes:

C1803-01: AIR SUSPENSION EXHAUST SOLENOID

U1266-02: TCU CONN

I can't find anything about them anywhere. Was going to call local Nissan dealer today but didn't find the time.

Anybody know what these are about?

Are those fault codes or pending or history?

Here is an old post with some info on the C code.

I don't know about the U code.

Your 2018 should be under warranty, no? I'd just let Nissan figure it out.

I called Nissan today to ask about these codes. The guy explained what I already knew; the C-code one has to do with the autolevelling solenoid, and the U-code had to do with the Transmission Control Unit. He basically said that if I didn't get a warning light there's nothing they're going to do. He said they're not going to swap out parts just because I got these messages. I said "so I have to drive it until it breaks?" He said, "yeah".

Are you having problems with the suspension and transmission? Is your check engine light on or not? If it's on, or you hare having problems, then you should take it in (under warranty I assume) to have it looked at.

If the light is not on then you probably just found what are called pending codes with your new scan tool. The CEL does not come on the second there is a problem. You car wants to see the problem present for X number of drives cycles or some combination of code setting conditions before it puts the money light on. If that is the case - then yeah, they are not going to look at it because there isn't a problem to look at.
