Daughter is driving the LR3 and said she is getting this message.

She says it makes a beep noise and then the message pops up.

I'm thinking she changed the range dial. She is going to check.

If not, any other things that can cause this?

 

Only thing I know of is switching from high/low range on the transfer case that causes this.

Only time I get the message is when I hit the lever when I’m still in gear. It hung around one time so I went back to neutral and cycled it back to low than into high. That cleared it

 

That message usually involves "Lo Range" on the transfer case. So either the T/Case switch is getting bumped or its shorting out (spilled fluids, left open sunroof, etc...)

 

OR....if she tries to select Rock Crawl maybe while driving???

Since Rock Crawl requires you to be in Lo Range.

 

Ok, so the "select neutral before range change" went away before she got me the truck. Now, when ever the truck starts off it is getting the "HDC fault system not available" message. And it is consistent.

Related?

 

Check where the terrain response dial is pointed to out of curiosity

 

It was all the way to the left, on Normal

 

I would try putting it in rock crawl on the terrain dial, put the trans in N, select low, drive it a few yards in a strait line then put it back to standard mode on the dial and put the t-case back in high range. Sounds like the dial or the t-case lever was messed with and now something is out of sync. It probably also wouldn't hurt to turn HDC off and back on while in rock crawl mode. If that doesn't take care of it it might be worth it to spend the money on a half hour of diag at a shop that can properly pull Land Rover faults.
