P0915 Gear Shift Position Circuit Range/Performance

Ok, so I've got this fun P0915-00 (2F) gearshift position - circuit range/performance fault that I cant clear. Ok the story so far. Jumped in the D3 this afternoon and straight off the bat I had the low range green dash indicator flashing along with a few other fault lights lit up. Had a transmission fault message (cant remember excatly what it said). Low/High range lights at the selector flashing. Restarted the car a couple of times to no avail. During the restarting process I could hear clicking under the car. Anyway drove to the young fellas soccer training and while he was doing that I plugged in the IID tool and scanned the codes. Mostly my normal fault codes, but the transfer had a single P186D-00 (28) Clutch actuator stuck code logged. Had a quick google search and decided to attempt to calibrate the transfer clutch, but nothing. Anyway I get it home and due to the noises I heard and the original fault code I've pulled the transfer shift motor, which I found to have a worn gear wheel where the motor worn gear runs - that would be the clicking when the gear is skipping a tooth. Had a play around at it seems I've only got wear on one half of the gear wheel so figured I may be able to spin the gear to run on the other half while I get a spare ordered. Plugged everything back in and now that

P0915-00 (2F) fault is up on the transfer and I cant clear it. Any ideas?

I've tried to do another clutch calibration, but I cant calibrate the high/low shift as the fault code will not allow me to make the high/low selection.
Tried a hard reset, no luck there either

This is interesting Shane as I regularly get the same symptoms (multitude of warning lights flashing, low/high range and height settings unable to be used, and a bunch of different warning messages flash across the display). Sometimes I have tried a hard reset, lock/unlock car 3+ times (is this an urban myth created by someone with some PC reset sense of humour), and even plugged in the IID tool and had no luck tracking down. And then after a day or two it would clear as if nothing ever happened.

The next time my 3 amigo buddies have invited their friends over for a disco party I will dive back in with the IID tool to see if I get the same error codes. I have been wanting to resolve this one for some time now. It does seem that different types of faults all come up with the same warnings and throw our Mexican Disco buddies into a spin.

Well, its just gotten worse - just put everything back together, now theres no drive at all. Definatly heard the shift motor grinding this time however. And the clutch actuator stuck fault code is back again. Now to go and pull the shift motor and hope I can replace it tommorrow

Sounds like going from bad to worse Shane. Are you having any wins yet?

We'll find out this afternoon as I haven't had a free moment to look at it

Feedback, new shift motor installed, ignition on and fault lights still up until the high/low switch used and everything cleared. All fault codes cleared with no issues and high/low and clutch calibrated. All good to go again. Rovacraft had the new motor to me the day after I ordered it (they had one in stock in Melbourne) so I'm happy there wasn't a long wait to get it
