Motorshield

Hi I have recently bought a VE wagon and noticed it has a small Motorshield device mounted in the engine bay.
Does anyone know what this might be for?

What does it look like? my guess would be some sort of electronic rust protection unit.

Oh yeah, that makes sense considering its connected to two earth points. Its about the size of a matchbox. It has an LCD but I cant read it.
Thanks axemurderer101
