That's normal for a 1D MK IV. Read page 96 of your manual (the note at the bottom)


"With AI Servo AF, the beeper will not sound even when focus is achieved.

Also, the focus confirmation light <o> in the viewfinder will not light."

The confirmation light is the little green light down in the lower right corner. It doesn't illuminate in AI Servo AF with any Canon EOS body.

That's an entirely different thing than the actual AF points lighting up or not. Some models do, some don't.
