So all's been well for a couple weeks, but today after driving down state and about half way home the CEL lit up. Once home put the GAP on it and found it had one code U-0102-00 - Lost Comms with Transfer Case Control Module (TCCM). Was cruising about 75-80 at the time. Not sure if this is a common connector issue (or not) under the hood (bonnet) with LR4s due to cabling/connector issues that develop over time as does happen with some other vehicles.

2 things come to mind - I glaced down at the dash as I had heard a "DING" Go off, which turned out to be the speed warning which was set at 80 (OK, maaaybe I was going a bit over). The other thought is I just installed a console cooler the other day (and it worked great today) which meant I had to raise the center console. Perhaps one of the connectors that control tranny/ride height/off road came a bit loose.

Any others with experience on the TCCM throwing a fault and first simple things to check?
TIA
