Parasitic drain - not HFT

Son has got a 2007 EX, but battery keeps dying. Put an ammeter on it and it's drawing 0.3 - 0.5A - pulling the fuse 16 "Back-up" eliminates the problem.
We've already disconnected the HFT module and all the doors lock OK.
We checked on the Honda website and there are no outstanding recalls (so presumably the MICU work has been done - how can we confirm that?)
Is there another likely culprit?

Have you checked out the interior lights.
Sometimes the switch may show "off" but the circuit still be live, thus draining battery.

As in the light still being on? - We did check interior lights were turned off (and actually went off) when we did the 10 min wait for the MICU to shut down.

No, the lights go out but for some reason the circuit stays live.
Need to check with meter.

OK - fuse 17 is listed as interior light, If I remove that and it stops the current draw, how do I then solve the issue - short circuit across a switch somewhere presumably?
