P38A ABS FAULT, TRACTION FAILURE

Evening Everybody,
Switched on this morning, and got ABS FAULT follwed by TRACTION FAILURE on the display.
Switched off and on again, and everything was fine again.
I haven't had a chance to get it on the Nanocom yet, and the drivers manual just says contact your local Land Rover dealer.
Any idea what the most likely culpirit might be?

Check battery voltage its a common problem

Battery is reasonably new so I hadn't thought of that! I shall though, What voltage should I be expecting at rest?

It should be 12.6 after 24 hrs after being fully charged. it may be that on starting the voltage dropped and initiated the ABS/TC lamps when the motor had run for a moment,the battery voltage may have lifted enough to not switch on the lamps.when you restarted it.

If it repeats I'd tend to back Wammers diagnosis

Thanks all. The voltage and wheels sensors are the easy ones to check so I'll start there.
Not going to be near a Nanocom for two weeks, so that'll have to wait.

Brake light switch

As i recall when my brake switch failed it only ever gave ABS fault not a TC fault.

I used to get it when reversing in to a parking space. Haven't had it for a long time now though.

low voltage and outside temperature !!!!!!!!!!!! combination of both ,,,,, sit there for 5 min with temp up and all disappears , its seems to me to be when interior is cold and damp !!!!! first thing in morning !!!!! try it . it works for me ,,,, battery should be throwing out 14.2 at least at 2000 revs ,,, MAIN SUSPECT CRAP OR WRONG BATTERY !!!!!!!!!!!!!!! INMHO

I've had the same usually when reverse parking downhill, never lasts, and next time I move it the fault has gone, I put it down to a sticky sensor, nanocom never shows a fault though, I recently replaced the accumulator, and rear pads so everything ok brake wise, I look on it as more of a minor irritation than a problem.
