The lens contacts are the row of small gold buttons just inside the lens mounting plate on the camera body. Check for and remove any visible contaminants. If you can't see anything that would be likely to cause a loss of contact, you could try cleaning the contacts. I would try a lens tissue moistened with isopropyl alcohol (or some other lens/sensor cleaning solvent) first. The other thing to try is rubbing the contacts with a pencil eraser, but watch you don't get debris falling into the camera body.
If neither of these solutions work, then the issue is likely to require a trip to Canon at Elstree.
Another thought, before you try cleaning the lens contacts:
How have you eliminated the lens as the problem? And, are you sure that the lens is locking onto the camera body? In my experience this error has always been to do with the contacts not making proper contact due to the lens mounting plate being out of spec.
My process of elimination consisted of a/ changing lenses. b/ changing bodies. No problem with my original 350 body. The conclusion being its the 1D3 body as the error message persists.
If the error message persists on the 1D3 with multiple lenses, and there is nothing physically interfering with the body contacts, then it is probably the mounting plate. Using long lenses can put quite a strain on the mounting plate and it can distort, especially when used hand-held. Send it or take it in to the Canon service centre in Elstree. I seem to remember a cost of somewhere in the £100-£150 range for that repair, but that was some years ago.

I think you have diagnosed the problem spot on. Thanks
