Rear Diff Fault

Quote:
P186D-00
Clutch actuator is stuck
General failure information - no sub type information

Possible causes:
Actuator fault

Quote:
U1A4A-68
Invalid data received from differential control module - rear
Algorithm based failure - event information

Possible causes
Event Information
Actions Required:
Check for rear differential control module diagnostic trouble codes. Refer to the relevant section in the workshop manual.


The history:

Back last November I was getting numerous faults and poor starting in the morning due to a failing battery. I got a couple of TRANSMISSION FAULT, HDC FAULT, SUSPENSION FAULT, SUSPENSION LOWERING... errors, but put this down to the battery.

Changed the battery. Still got the faults.

No noticable problems / noise apart from that. If I stop the car, remove key, wait a little and restart all is fine.

There was a TSB for the rear diff some time ago - did you have it done.

It may be totally unrelated, but worth checking..

Thanks Duncan Thumbs Up I'm not sure I've had that. Off to check...

Edit: Can't find any paperwork for it. Gotta wait until tomorrow to ask, unless anyone is bored can look up a VIN for me?
