Safety Recall N23 for WH anyone had it done yet?

[Clarky]

It's already locked out by the stored code and only the light is triggered at the attempt to engage.

Hi Hanna, Clarky has answered it, but just to be double-clear...
The computer only actually checks the signal from the transfer case motor when the car is started, not each time you shift into 4Lo.

So to try to cause the error like you asked the prev. owner to do, you need to actually turn the car on, shift to 4lo, shift back, turn car off (which means waiting some time for the computers to power down fully.) and repeat.
If the transfer case motor is 'border-line', testing repeatedly like that may eventually give the error.

Testing while everything is hotter (say after some 4wding) would also increase the chance of it happening (because there'll be more electrical resistence and maybe some movement in the position sensor.).

You're picking the car up today ay?
Try 4lo a few times on the drive back, maybe each time you stop for a break (if you do.) then again before you start driving again.

Enjoy the drive anyway. I got my WH from Melbourne, the drive home was good bonding time .

After my first post in 2013 about the N23 recall i was on the way to the airport to drop my wife off when she said i forgot to tell you a service 4wd system light has come on in the jeepwhen i got home checked jeep and sure enough no 4low done the fuse trick checked connectors on TC still no good,plugged in GDE scanner to check for codes and got P0671,P0673,P0676.but i can't find a listing for those codes,all the list that i've found seem to skip the P067 range,if anyone knows what my next step should be your input would be very much appreciated thanks Mike.

P067X are glow plug codes. So that's plugs on cylinders 1, 3 and 6.
Probably unrelated to the service 4wd message.

I don't think the GDE scan tool can display the fault codes related to N23, but James is right, the codes you are seeing are related to glow plugs.

I believe that they relate to the glow plugs:

Testing: To test a glow plug put on an ohmmeter and check resistance. If the resistance is low (3 ohms or less) then they are good but if it goes up to a high number 100+ then it is bad and needs to be replaced.

OBD2 Codes: The following CEL codes you will get if one goes bad: P0671 (plug 1), P0672 (plug 2 and so on), P0673, P0674, P0675, P0676.
