Lan mode 2

[340valnt]

Has anyone completed mode 2 in self diagnostics 1: push defrost 10 time 2: step light comes on 3:push defrost again and hold while turning key on.Is that right? Do you keep holding it or let go .Then what's suppose to happen? I know it's checking switches are they supposed to be turning on. 96 q 45 Trying to fix locks locking automatically when door closes or just triggering when you hit the unlock they unlock and immediately they lock again . Also drive positioning not working. Everything works fine independently

I've had 3 Q's (91t, 92, & 94t) and even when everything worked, not all the tests worked.
I do recollect doing that on one or more of my Q's, (I have an M now), and that magic incantation worked.

Try this for the drive positioning:

AUTOMATIC DRIVE POSITIONER RESET

Before you start the procedure, remove the neg. cable from the battery,(for about 5 to 10 minutes has worked for me) put the cable back. I have used dielectric grease on the post( since I have not had the problem) make sure you have a better than good contact. Now you can start the procedure.

1. Open the driver's door
2. Turn the key to the Run position
3. Turn the key all the way back off, but don't remove the key
4. Close the door
5. Wait about 1 minute
6. Open the door; the memory function should work now.

The likely cause for that issue is the LCU in the door. I'm with Eric, I've had a fully functional Q and I've never been able to quite get the self diagnosis to work... My Q has locked itself twice, both times were in my driveway while I was washing her (the nerve!!)

I would imagine it has to be either of the front door LCU since the unlock/lock cycle is happening (that wouldn't happen with the rear door). I'm not sure those are available anymore through Infiniti, but it'd be worth a call to Dan at Infiniti of Scottsdale.
