Possibly, but as the centre diff is shown locked the rear may also start-off locked. However the point is that mine also shows a green rear diff lock yet I know that mine does not have an e-diff, so the green symbol is not an indicator of the presence of an e-diff on these vehicles. I know that later D4s don't show the rear diff green if no e-diff whereas earlier D4s do, same as D3s.
