I have been having a parasitic draw on my 2006 GS300. The battery will either be dead within 3 days or sometimes overnight. I put a multimeter in series on the negative terminal. I was measuring DC amps of 1.3A while car is off. I began pulling fuses and didn't see any change until I got to the DC Cut fuse on the passenger side fuse compartment in the engine compartment. After I pulled the fuse out the amps dropped to .1A. Does anyone know what the DC Cut fuse feeds? Does anyone have a schematic or wiring diagram? Any suggestions?

But before looking for what that DC fuse is for, do you know what is the Gs 300 normal current draw? Or ruled out a defective battery?

There is a fuse box diagram from the website, below --

The information in there seems accurate to me, but I am no means an expert. The D/C Cut appears to be Fuse 6 in the engine compartment, and is rated for 20 AMPS.

Have you checked your steering auto lock and auto retract mechanism? Is it moving freely?

The tjing is that fuse controls the mpx-b which consists in a bunch of components. Try getting yourself locked in the car and listen to noises. Playvspexial attention to the steering column. Probably it's getting stuck and keeps on trying until it frains your battery. That's what occurs to me

It has been a few days of rain so I was not able to test. I was however able to start the car without any issue since pulling the fuse. So it looks like the issue is somewhere in this circuit. I closed the door and turned off the car. The steering wheel went back in fully and then stopped. I did not hear any other noises.
