I started up my 2012 LR4 w/rear diff this morning and noticed a "service required" message flash on the display for a few seconds - I think I just forgot to reset the service reminder in my last oil changes, but the message prompted me to plug in the GAP IIDTool and look for faults. Unfortunately, I'm seeing this one:
P0807-00 (7F) Clutch position sensor - circuit low
(RDCM-Rear Differential module)
I cleared faults and this triggered again right away. Any ideas about diagnosis from here? Searches don't reveal much of anything LR4-specific about this code; I do see LR3 threads though with similar rear diff codes discussing issues ranging from control module to rear diff replacement.
No check engine light or performance issues of any kind on my end, newish battery, 117K miles, no other clues. FWIW there was one other electrical fault on the IIDTool, B1163-15 (2E) for left mirror heater output "general electrical failure - circuit short to battery or open", triggered a few days ago.
Thanks for any ideas!
