0.467mA Parasitic Draw - Never mind

:icon_redface:

When I checked the owners manual instead of the sticker on the interior fuse box door it said the fuse that was drawing current was for the keyless entry and luggage light. I don't have keyless entry and sure enough, when I pulled the fuse the luggage light won't work. Problem solved as the luggage light is basically useless.

I sure wouldn't be concerned with a parasitic draw of 0.457 mA.
My Honda Goldwing motorcycle has a maximum acceptable (designed) parasitic draw of 5 mA, which is 10 times greater than what your Subie is drawing.
Have you tried hooking a digital ammeter (multimeter) in series with the negative battery cable and terminal instead of a clamp-on?
Clamp-ons are generally not as accurate as actual current testing with a good multimeter.

Thanks for the reply and suggestion. Since the fuse doesn't do anything useful for me, I'm just going to leave it out and go with the lower parasitic draw.

The luggage light should only come on if the door is opened? It should not affect the parasitic draw (dark current) when the car is unattended. 0.4mA (0.0004A) is essentially nothing. Some draw is normal in order to keep various electronics awake - clocks, receivers, etc. Nothing at all to be worried about.

Was that "parasitic" draw with the cargo light off (i.e., the hatch was closed)?

I can't think of why an OFF light would draw any current.

The keyless entry would refer to the remote buttons on the key wouldn't it? Not the smart key. The system would need constant power to receive signal from your remote.

Try test if you can remote unlock the doors with the fuse removed.
