Hello. Got a 2007 TSX with a great maintenance and owner history. Only aftermarket parts are depo headlight housings (factory bulb setup) and led interior lights (installed years back). A year ago the battery started dying, I replaced both the battery and alt (old-ish battery and factory alt, 240k miles). A few months later and it started draining again, so after some quick research I unplugged the HFL which solved the issue till now. Car draws about 1.2a when sleeping. Popping out fuse 6 and 7 drops the draw to ~20ma, each of them cut the draw in half. Found that the ground cable was loose and corroded, replaced that to no avail. Power locks, windows and trunk work just fine. One interior led doesn’t turn on, and a while back I noticed some water that had leaked into the trunk. Unplugging the trunk latch seems to drop the draw to about 900ma. I’m stumped at this point, and afraid I’ll have to dig into the MICU. I can’t seem to find much info on diagnosing it before spending the time and money to replace it, or where else to look other than tearing the car apart and seeing what else I can unplug.

Any input or advice would be greatly appreciated! Learning a lot here.
