This are voltages read live using my Gap II diagnostics of the ride hight sensors. When the 4 corners are calibrated to the correct ride heights. the most obvious thing is that the voltages on the RHS front & rear of the vehicle are markedly lower than those on the LHS.

This is off a RRS 3.0L diesel, MY2011.

Any ideas why this should be so and if there is anything that I should be so concerned about.
