Defender 2009 HI/LO range indicator

Forgot to add to my last comment how to use the info given:

Without a nanocom you can tell if the signal is getting through.

Go into lo range. Select 1st gear and let the clutch out with no applied throttle. You are now puttering forward slowly at idle revs, and just a few seconds after the clutch is fully out your idle revs should go up from around 800rpm to about 1100rpm. If so the signal is getting through.

Just to be clear there are three conditions that need to be met to see the idle jack feature kick in (idle revs raised):
- Lo range selected
- 1st or reverse selected
- clutch pedal fully up

If you were to now give it a bit of a thrash through the gears while in lo range you should notice that the throttle response is quite different to when in hi range. Again shows the signal/switch are all working as they should.

Great advice, I'll give that a go!

I plugged my nanocom in this morning and scrolled through every possible screen, as far as I can tell there is nothing to say whether the transfer is in high or low.

As others have said, no high-low light on my 2009, but there is an indicator for the centre diff lock.
My TC is definitely working and I have seen it stop spinning wheels. When you start and drive off the TC light should be on and then it goes off at about 8 km/h I think from memory.
Is there a fuse specifically for the TC? I haven't looked.
Putting it in low range changes various characteristics.
Idle up definitely works in low range on mine. I can take my feet off the pedals and it will idle over obstacles without stalling. Great feature - my BIL with his 80 series really envies it, since he stalls a lot.
Hope that helps.
