It's called the Central Junction Box (CJB), and is part of the inside fuse box, behind the glove box.
What is wrong with it?

Not sure there is anything wrong with it, today my jlr sdd diagnostic arrived gave me several faults the main one being B10A2 crash signal permanent. I am having a lesson tomorrow eve from the seller of diagnostic. I thought with the other re occuring faults it may have water ingress. The faults all started around my purchase mileage so wondering if selling garage jet washed it to the death.

The CRASH warning is normally generated by a sudden drop in battery voltage to below 8 Volts, this can happen if the battery suddenly dies while cranking the engine.
It's easy to clear the crash code with SDD.
SDD can do a full vehicle diagnostic, but it doesn't remove any stored codes, as those build a running history of errors, which SDD can use to pinpoint future faults.
Clearing codes of historic items isn't helpful or recommend, as any potential help from intermittent or minor faults is lost.
SDD isn't too difficult to use, at least not if you've had past experience with dealer level diagnostic equipment.

The crash code won't effect anything, after the ignition was cycled after it was first generated.
Each item that isn't working will generate its own code.
