How do I get my Canon 70D to detect my Tokina ATXAT-X 400mm not detected on 70Dlens?

I have recently purchased a used (but remarkable condition) atxTokina AT-X 400mm f5f/5.6 with an efEF mount. This works on my 6D, allowing for aperture and focus control from the body.

However, my 70D doesntdoesn't register it at all: the display shows an aperture of 0.0 and selects manual focus in drive menu. While the lens is functional, it would be nice for it to work with the higher frame rate of the 70D. I also have the atxAT-X 300mm f4f/4 which works perfectly on both (hence this purchase).

What should I check / examine / investigate to get this working on my 70D? Has anyone experienced this or similar (old lens ->→ new body)?
